This patent application is a continuation-in-part of U.S. patent application Ser.

No. 16/974,284, entitled, “Clear ice cube making device,” filed Dec. 16, 2020, which claims the benefits of U.S. Provisional Ser. No. 63/102,512 , entitled, “Popsicle device,” filed Jun. 19, 2020, which are incorporated herein by reference in their entireties.
The present invention generally relates to the field of ice production, specifically to an apparatus and method for producing large, hard one directionally frozen ice that is void of visible bubbles. The invention also encompasses novel methods to freeze the ice using an undersized liquid refrigeration line in combination with agitation and an ultra-low temperature refrigerant.
The invention solves the problem of making clear ice cubes without bubbles and a visible dimple measuring over 1.70 inches, by over 1.70 inches by over 1.70 inches and less than 2.5 inches by less than 2.5 inches by less than 2.5 inches, without cutting the ice or breaking impurities from the ice piece after it is formed and where all the water in the cavity is frozen. There is no clear ice machine that makes clear ice pieces for human consumption without a dimple in the above measurements without cutting ice where all the water in the cavity is frozen from only the bottom of the cavity to a top open position of the cavity.
Large clear ice cubes sell at a premium price and the largest clear ice cube made without cutting the ice cube or breaking impurities from the ice after it is formed and that has no dimple is about 1.5 inches cubed. The present invention is a major breakthrough in clear ice cube making technology. The Hoshizaki Service Manuel incorporated herein by reference in its entirely makes the largest clear ice cube in 2025 without cutting the ice. The introduction of the system in the marketplace has had mixed results due to the large visible dimple as depicted in item 2710B herein in the ice cube where water that is warmer than the forming ice piece contacts the ice being formed in the cavity. Page nine shows the Hoshizaki release opening to about scale having a diameter that is much smaller than 30 percent of the diameter of the cavity. The present invention substantially reduces or eliminates the dimple. On page nine the water release opening of the Hoshizaki is shown to direct water impacting just the center of the cavity which would have an ice cube being formed creating a rather larger visible dimple such as seen in 2710B. Hoshizaki does not fairly suggest using water that has less than 188 milligrams per liter of water. This is a critical feature of the present invention. In making normally frozen non-one directionally frozen ice water is placed in a cavity and frozen. High concentrations of calcium carbonate over time found in most cities water supply changes the continuous waterflow of water into the cavity resulting in a less than superior ice piece that commands no premium pricing over multi-directionally frozen ice cubes. The cubes also become cloudy. Kold Draft Ice Company specification sheet entitled Kold Draft Cocktail Ice Machines is incorporated herein by reference in its entirely is thought to be the largest producer of clear cocktail ice in the US. The largest clear ice cubes made by Kold Draft is 1 inch by 1 inch by 1¼ inches. The picture on page 2 shows a huge dimple in the ice piece.
To reduce a dimple size the release opening of the present invention has a diameter over 30 percent of the diameter opening of the cavity which is not fairly suggest in the art except for the present invention. To eliminate the dimple the release opening is sized having a diameter sized about 80 percent, or at the same size, or larger than the size of the diameter of the cavity diameter opening. This allows the ice piece to freeze outwards from a bottom wall of a cavity about uniformly. One or more release openings collectively or separately have a diameter sized of 80 percent of a diameter size of a top opening of the cavity. One of ordinary skill in the art would know how to accomplish this goal from reading this disclosure. The present invention forms freezes all water in a cavity to form the ice piece which is not known in the art for making clear ice with vibration.
Adding further safety an embodiment uses a food safe lubricant. “Food safe” goes beyond using just “food grade” and should not be confused or used in place of food safe. While all food-safe materials are food-grade, not all food-grade materials are considered food-safe in every situation. The term “food-safe” elevates the criteria, focusing not just on the material's composition, but also on its performance under specific conditions. Embodiments provide that even the lubricant inside the water pump in addition to just providing the lubricant to water touching aspects outside the pump is food safe. While one of ordinary skill in the art knows the difference between food grade and food safe the present invention is the only one directionally frozen ice machine that makes one directionally frozen dimple free ice from the bottom of a cavity for human consumption that teaches or fairly suggests the entire system and method is food safe.
The present invention is not only food complaint the blades are configured for mass production cutting of hundreds of ice cubes at a time while providing a superior cut over other food complaint blades. The present inventions configured blades are the only sanitary blades that mass cuts over 500 ice cubes without having to stop the blades from cutting to cool the blades. They cut over 100 of the cubes without needing to sharpen the blades. And they cut hundreds of cubes without visible chips and visible internal cracks in an ambient air temperature range of 40 to 90 degrees Fahrenheit without causing thermal shock to small ice cubes that result in visible internal cracks.
The quest for creating the perfect transparent ice cube 1.70 to 2.50 inches that is legally sold in the United States to commercial venues without a dimple, lacking visible cracks, lacking visible chips without cutting the ice has been fraught with challenges, particularly in the context of mass production of ice for human consumption and legal sale within the United States.
Traditional methods of ice production have often fallen short in delivering ice that meets the high standards of clarity and purity demanded by consumers and high-end establishments and for legal human consumption sale. The present invention ice commands a premium price over other ice cubes. Consumers seek large, flawless ice cubes over 1½ inches cubed that are devoid of bubbles, cloudiness, cracks, crystallization, and any milky appearance and dimples which can otherwise detract from the visual appeal and taste experience of beverages.
Existing ice-making technologies have struggled to control the freezing process adequately, resulting in ice cubes with visible imperfections. These imperfections are often due to the entrapment of air and impurities within the ice as it freezes, a common issue that prior art has not effectively addressed without cutting impurities from the ice. Moreover, the process of cutting larger blocks of ice into smaller cubes has been problematic, with a tendency for the ice to chip and crack especially when mass cutting many ice cubes at a time.
Prior art, such as the teachings of Lawrence in Patent Cooperation Treaty Patent Application PCT/US2007/084787 filed on Nov. 15, 2007, which is hereby incorporated by reference in its entirety, discusses the concept of clear ice and suggests methods for its production. However, Lawrence's disclosure reveals inherent limitations and misunderstandings in the approach to creating truly transparent ice cubes with vibration. For instance, Lawrence's method does not adequately prevent the formation of visible bubbles within the ice, nor does it suggest a means to maintain thermal communication between the refrigeration pipe and a freezing surface having a refrigerant therein having a boiling point colder than about −30 degrees C. at 1 atmosphere pressure, which is crucial for achieving a high-quality large transparent ice cube over 1.70 inches by over 1.70 inches by 1.70 inches over 1.70 inches with the desired density in the mass production of ice for human consumption and legal sale within the United States. There is no prior art that fairly suggests using an ultra-cold refrigerant to make the present inventions desired ice piece size without cutting the ice. Lawernce is shown placed in a refrigerator/freezer for home use which is not known to use a refrigerant with a boiling point of the present invention. There is no clear ice that is made without cutting the ice that utilizes a refrigerant with a boiling point as low as the present invention. Lawrence further subjects the vibrator to freezing temperatures as it is shown in an enclosed compartment of a refrigerator/freezer. Lawernce does not fairly suggest a refrigeration pipe is insulated to prevent extreme below freezing temperatures to contact the outside surface of the Lawernce vibrator that houses internal moving parts. Freezing temperature from ultra-cold refrigerants creates frost on the warmer internal moving parts making amplitude and frequency erratic creating the visible bubbles in the Lawernce ice. Lawernce teaches away from keeping the temperature above the top surface of the water between 50-90 degrees F. because it is placed inside a freezer so the top surface of the water would freeze before water under the top surface freezes. Therefore, it is impossible for Lawernce to make clear ice void of bubbles. There is no suggestion that as a standalone unit Lawernce would be able to make a clear ice cube without bubbles. It takes the proper vibration amplitude and frequency throughout the freezing cycle together with insulating the pipe so not to freeze or inhibit the movement of the vibrator internal moving parts and keeping the ambient air temperature above the surface of the water between 50-90 degrees F. It takes all these together with the present inventions unique refrigeration system to make large clear ice without bubbles and dimples.
Devices such as that disclosed U.S. patent application Ser. No. 18/253,706 filed on Nov. 19, 2021, which is hereby incorporated by reference in its entirety, cause chipping when cutting the ice as it discloses collecting or discarding ice chips. As those in skilled in the art would appreciate, the aesthetics associated with ice that has been chipped such as the ice portions created in association with the invention disclosed in the '706 patent application mentioned immediately above are of a much less desirable quality than ice portions that are created lacking any visible cracks and any visible chips. For the most dense ice the water used to make the ice has less than 220 milligrams of calcium carbonate per liter of water and most preferably less than 188 milligrams per liter of water.
Additionally, the Kirkpatrick reference, U.S. Pat. No. 2,414,264 filed on Apr. 3, 1945, which is hereby incorporated by reference in its entirety, presents its own set of problems and challenges in the realm of transparent ice cube production. Kirkpatrick purports to provide an apparatus for making crystal clear ice cubes, yet the method outlined therein fails to incorporate a critical aspect of ice cube production—unidirectional freezing. Without this key process, it is scientifically implausible for Kirkpatrick's apparatus to produce truly transparent ice cubes. Lawrence does not suggest all the water in the cavity is frozen and Kirkpatrick and others suggest this is where visually impurities accumulate. Therefore, Kirkpatrick does not make clear ice because the top of the ice is disclosed as having impurities. While the present invention can provide a layer of water on top of the ice piece this layer of water is not necessary in the preferred embodiment. The vibration amplitude and VPM and cavity configuration and refrigeration system is such that all the water is frozen in the cavity and the only frost may appear on top of the resulted ice due to humidity impacting the top of the ice after the ice is formed. This frost melts or is brushed away and is not an integral part of the ice.
The prior art also includes varying characterizations of what constitutes “clear ice.” In particular, Lawrence provides a definition of “clear ice” allowing for a certain degree of visible internal impurities, such as bubbles and cloudiness, up to approximately 25% by volume. This tolerance for imperfections would not meet more stringent standards, which aim for ice cubes that are devoid of visible crystallization, visible bubbles, visible cracks, and a dimple ensuring a higher level of clarity and surface esthetics.
When cavities are filled with 20 pounds of water the outside walls move outwards. This increases processing of an ice piece. To solve this problem the present inventions cavity is made of rigid silicone having a Shore hardness harder than 30A when making large blocks of ice. The sidewalls have a thickness over one half of an inch and the bottom wall has a thickness range of one eight of an inch to five eights of an inch so the sidewalls do not flex outward when the cavity is filled with over twenty five pounds of the water. The thickness range provides that heat is drawn from the water through the thickness of the bottom wall to freeze the water to make the ice piece.
An ice tray that freezes water from the top down does not provide the density of ice made with a refrigeration pipe under a cavity freezing water from a bottom position of a cavity to a top position of the cavity as the present invention provides. They more importantly trap visible impurities. Those systems do make 2″ cubes, however, they require cutting or breaking off the impurities from the formed cubes after all the water in the cavity is totally frozen. See for example Antarctic Clear Ice Maker page 2 that is incorporated herein by reference in its entirely. “The design was engineered to force water to freeze from the top down pushing impurities down into a reservoir tank below the ice mold.” The frozen impurities in the reservoir are cut or broken from the ice piece.
A key aspect of the invention is the utilization of a refrigeration system that includes a refrigeration pipe measuring over 25 equivalent feet in length, over ½ inch of an inch in diameter, with a refrigeration compressor assembly that outputs over 1,000 British Thermal Units per hour and extending from a refrigeration expansion valve an undersized diameter liquid line that has a diameter of less than ⅜ths of an inch. The cavity is in thermal communication with the refrigeration pipe or a plate (freezing surface). The system using vibration is designed to vibrate the refrigeration pipe, or agitating the water in such a way that droplets jump significantly above the water surface. The frequency is between a range of 700 and 3,000 vibrations per minute, and the refrigeration pipe is insulated so freezing temperatures do not reach the vibrator. With vibration an ambient temperature is subjected 1-5 inches above the surface of the water in the cavity. The present invention makes ice lacking visible bubbles, visible crystals, visible cracks, and visible chips. Due extremely cold boiling point of the refrigerant between a range −40° C. and −62° C. the ice is denser which makes superior ice. With this range the refrigerant suction temperature is colder than −10 degrees F. The present invention makes clear ice over 1.50 inches by over 1.50 inches by over 1.50 inches and more preferably over 1.70 inches by over 1.70 inches by over 1.70 inches and less than 2.5 inches by less than 2.5 inches by less than 2.5 inches without a visible dimple in the ice and without cutting the ice. The Holy Grail the present invention achieves is making the most premium priced sought after multiple ice pieces that are a full 2 inches cubed compared to other machines on the market where the ice is not cut that can only achieve freezing water from the bottom wall up a little over 1.5 inches when making multiple ice pieces.
The system is designed to vibrate or oscillate the refrigeration pipe, agitating the water in such a way that a droplet jumps significantly above the water surface, thereby mitigating the formation of visible bubbles within the ice cube. The preferred system is designed to vibrate or oscillate the refrigeration pipe, agitating the water in such a way that droplets jump significantly above the water surface, thereby mitigating the formation of visible bubbles within the ice cube. The agitation device is not subjected to freezing temperatures to disrupt the amplitude. The present invention makes one directional frozen ice to a specification. Embodiments make ice lacking visible bubbles, visible crystals, visible cracks, visible chips and visible bubbles (impurities) and has six side surfaces that each measure 1½ to 2½ inches meeting all codes for commercial legal sell or commercial legal charge for the ice in the United States. It allows commercial bars and the like to legally place the ice in a beverage. In one embodiment of the present invention the ice is formed in the same cavity the ice is sold. This save in having to package the ice it. There is no invention where the cavity (mold) is configured specifically for this dual purpose making and selling the ice in the same mold except for the present invention. The specifics of each cavity herein used with vibration are outlined giving material and thickness to achieve this goal.
A distinctive aspect of the preferred embodiment is an ice tray that serves a dual purpose: it not only forms the ice cubes but also functions as the final packaging for the end user. This dual functionality streamlines the process by removing the need for additional repackaging, which is a standard practice in the bulk non-one directional frozen ice cube industry. This approach not only reduces packaging costs but also addresses a common issue in ice cube distribution, ice cubes sticking together after packaging. In accordance with the preferred embodiment, the present inventor has recognized that when larger ice cubes are sectioned into smaller sizes, these smaller ice cubes are then placed into a specially designed package. This package features individual cavities tailored to each ice cube, effectively preventing the cubes from fusing back together during transport or storage. This aspect materially differs from known prior art that offers transparent ice cubes sold directly in the manufacturing tray, and therefore represents a significant departure from traditional practices.
Embodiments utilizing a water pump reduce or eliminate a visible dimple in the ice piece.
In summary, the present invention provides a novel and non-obvious method and apparatus for making and legally commercially selling in the United States 1½ to 2½ inch transparent ice cubes that are structurally sound, clear, and energy-efficient, with a significant improvement over the prior art.

The present invention employs specific terminologies to define various aspects of the disclosed embodiments. The term “visible” refers to what can be seen by a human with 20/20 vision in both eyes without any visual enhancement when exposed to sunlight. An “ice cube” or “cube” is not confined to any particular size or shape and encompasses any shaped or sized ice, unless specifically claimed otherwise. The terms “includes” and “including” are intended to be inclusive, similar to the term “comprising.” The term “or” is also intended to be inclusive, meaning “A or B” should be interpreted as “A or B or both.” Approximating language is used throughout the specification and claims to modify quantitative representations that could vary without changing the basic function they relate to. Such language includes terms like “about,” “approximately,” “substantially,” and “substantial,” which are not limited to the precise values specified. These terms may correspond to the precision of an instrument for measuring the value, potentially being within a ten percent margin. “Food safe” means meets or exceeds all United State codes for processing food. “Human consumption” herein means the present inventions method and apparatus meets all United State codes to make an ice cube for human consumption and legal commercial sale within the United States. Further that the materials used are not only food grade but also food safe for making one directionally frozen ice. A “motor” refers to any suitable drive motor and/or transmission assembly. A “seam” is defined as a line of junction formed between two surfaces. An “ice mold” is any structure in which water is frozen. The “center” of an “ice cube” refers to the absolute center point of the cube, unless claimed otherwise. “Substantially” or “about means 90 percent or more. “Agitate,” “agitation,” or “agitated” refers to any water movement in a cavity, including water released into a cavity during the water freezing process. The term “one directional” or “one directional freezing” means water is frozen in a cavity from only the bottom wall of the cavity towards an open end of the cavity. The term “impurities” means visible bubbles and visible crystallization. This term and this meaning is widely used in the art.
Code approved ice making machines for clear ice in the US use a refrigerant such as R134A. It has a boiling point of −26.3° C. (−15.3 ° F). The present invention preferred embodiment uses a blend refrigerant such as but not limited to R452A having a boiling point of −47° C. 1 atmosphere (atm) pressure. R134a is a single-component refrigerant with lower pressure and capacity used in medium-pressure applications like automotive and domestic refrigeration/freezers. They have different pressure levels, boiling points, and system component needs, making them incompatible. Using the wrong refrigerant will damage the system and lead to costly repairs. See AL Generated Low Boiling Point vs Higher Boiling Point Refrigerant which is incorporated herein in its entirety.
In the context of the vibration, the term “vibrations per minute” (VPM) refers to the rate at which vibration or oscillation occurs within a given time period. It is a measure of how often the water in the ice mold is agitated back and forth or up and down during the freezing process. VPM is a relevant parameter in the process of making transparent ice cubes as it influences the movement of water molecules and the release of air bubbles trapped during the freezing process. However, VPM does not correlate directly to amplitude in the context of the invention, as VPM and amplitude are independent parameters that describe different characteristics of the agitation process used to create transparent ice cubes in the context of the invention. While VMP relates to the number of oscillations per minute, amplitude pertains to the strength or extent of those oscillations. The invention's focus on amplitude, particularly the critical amplitude and VMP combination necessary to achieve transparent ice cubes, sets it apart from the less effective attempts and represents an innovative step in the field of ice cube production. There is no prior art that fairly suggest this amplitude and VPM combination for vibration and this combination is critical to make the superior ice.
“Amplitude” refers to the measure of the intensity or the magnitude of the vibration or oscillation. It describes the height of the wave or the maximum extent of the vibration from the resting position. In the preferred embodiment, amplitude and the VPM is specifically controlled to ensure that water droplets are propelled at least one-eighth of an inch above the water's surface. This precise control of amplitude and VPM is essential for preventing the entrapment of visible bubbles within the ice cube, which is a key aspect associated with the preferred embodiment of the invention. This amplitude and VPM is critical to the process associated with the preferred embodiment, as it ensures that the induced water droplets contribute to the one-directional freezing necessary for creating transparent ice cubes without the undesired crystalline structures. It is also a key factor in disrupting the molecular alignment that leads to visible crystallization. In the context of the preferred embodiment, “amplitude” may refer to the magnitude or intensity of the vibration or oscillation cycles applied to the water within the ice mold, which is distinct from “VPM,” the term that describes the number of vibration or oscillation cycles occurring per minute. An aspect of one embodiment of the present invention is having the right amount of water amplitude and VPM to make a transparent ice cube with a center void of visible crystallization, void of a visible bubble. Unlike amplitude, VPM alone, regardless of its value, does not guarantee the desired elevation of water droplets in the context of embodiments of the invention; it is the amplitude's role to provide the necessary energy to propel the water droplets upward. VMP is the number of vibration or oscillation cycles (usually per minute) and amplitude refers to the violence of each cycle. Therefore, the invention carefully distinguishes between these two parameters, in the preferred embodiment optimizing both to achieve the highest quality of clear ice cubes.
For further clarity, VPM pertains to the rate at which vibrational cycles occur. However, the mere count of these cycles is insufficient to induce the necessary movement in water; it is the amplitude and VPM that provides the essential energy to propel water droplets within a range to make bubble free cubes. Without adequate amplitude, even with a high VPM, water droplets will not achieve the requisite elevation of at least one eight of an inch above the water's surface and less than seven inches above the water's surface. Higher amplitude could result in the undesirable trapping of air bubbles within the forming ice cube in the context of embodiments of the invention. The optimal frequency is in a range of 700 to 3000 vibration per minute. The amplitude is configured so nearly all water droplets (over 70 percent) are observed to leap the specified one eighth of an inch but no more than seven inches, and then return to the water, ensuring the formation of a transparent ice cube without visible air bubbles and other visible impurities.
The distinction between VPM and amplitude is crucial in differentiating the invention from less optimal attempts present in the prior art. While such attempts are associated with methods of agitating water during the freezing process, it has been left to the present inventor to discover the critical amplitude and VPM required to achieve the desired level of transparency in ice cubes. In the context of the preferred embodiment, specificity regarding the amplitude and frequency necessary to prevent the formation of visible bubbles and crystallization within the center of the ice cube is a key differentiating aspect of the invention. It is further the combination of the present inventions specified one directional freezing together with the present inventions cavity configuration and refrigeration system that makes the present inventions superior ice.
The preferred embodiment of the present invention not only recognizes the importance of VPM in the agitation process but also emphasizes the precise control of amplitude. The method associated with the preferred embodiment ensures that the agitation is vigorous enough to cause water droplets to jump above the water's surface, which is a key factor in producing transparent ice cubes devoid of visible impurities. The criticality of the measured range of amplitude in association with the preferred embodiment cannot be overstated, as it is a pivotal factor in achieving the desired quality of transparent ice cubes. The preferred embodiment specifies that the amplitude and frequency of the water agitation must be such that water droplets are propelled at least one-eighth of an inch above the water's surface and less than seven inches. This precise amplitude is essential for ensuring that air bubbles, which are naturally present in water, are released and do not become trapped within the forming ice cube. If the amplitude is too low, the water will not be agitated sufficiently to release these bubbles, resulting in ice cubes with visible impurities, as is evidenced by prior art attempts. Conversely, if the amplitude is too high, it could lead to excessive turbulence, causing the formation of visible bubbles in the ice. Therefore, the specified amplitude range and specific frequency range is critical for the process, as it directly influences the expulsion of visible air bubble impurities from the water, leading to the production of ice cubes with the highest level of clarity and structural integrity. This requirement for a specific amplitude range and frequency range to achieve transparent ice cubes devoid of visible crystallization, clear bubbles, and cracks is a distinctive aspect of the invention that differentiates it from prior art and underscores its innovative approach to ice cube production.
To achieve the present invention goal of making large one directionally frozen clear ice, the preferred embodiment is equipped with approximately 66 equivalent feet of ½ inch diameter refrigerant pipe, which is integral to the efficient transfer of thermal energy. The compressor assembly outputs over 1,500 British Thermal Units per hour (BTUH). A liquid line measuring less than ⅜ths of an inch extends from an expansion valve. FIG. 2805 shows a refrigeration pipe size chart that recommends not less than a ⅜ths of an inch diameter liquid line for refrigeration pipe with a diameter ½ of an inch or larger and an equivalent length over 25 feet with a compressor assembly outputting over 1,000 BTUH. Further the Hussmann Refrigeration Line Sizing, which is hereby incorporated by reference in its entirety shows that for any ½ or larger diameter piping requires a minimum ⅜ths in diameter liquid line. These charts as all refrigeration charts teach against using a liquid line that is less than ⅜ths of an inch in diameter for the refrigeration system configuration of the present invention. While some piping charts might vary slightly depending upon the exact specifications of the manufacture of the compressor assembly, all show a ⅜ths inch or larger diameter liquid line for immediately preceding configuration of an embodiment of the present invention.
The preferred embodiment specifies a refrigeration system that delivers sufficient BTUHs to produce transparent ice with a Moh hardness of 2-6. The refrigeration system itself in the context of embodiments of the invention is designed to deliver substantial cooling power, providing over 1,000 BTUs in embodiments and, in association with the preferred embodiment, in between 2,200-5,000 BTUH. This configuration serves as an illustrative example and is not intended to limit the scope of the invention. For comparison, brass—a metal known for its relative softness—has a Mohs hardness of 3. Those skilled in the art will appreciate that the hardness of ice varies with temperature: at its melting point, ice exhibits a Mohs hardness of 1.5, but this hardness can increase significantly under colder conditions. For instance, at −44° C. (−47 ° F.), the hardness of ice approaches 4, and it can reach a hardness of 6 at −78.5° C. (−109.3 ° F.), which corresponds to the sublimation point of solid carbon dioxide, commonly known as dry ice.
The present invention uses a refrigerant with a boiling point of about −40° C. to about −62° C. These variable are known in the art and are not fairly suggested in prior art for freezing one directionally frozen ice that is made in a clear ice machine for only making ice cubes for human consumption without cutting the ice. Code approved food safe ice machines specifically made to make one directionally frozen ice use a refrigerant with a boiling point generally about −11° C.—about −26° C. (12° F.-14.8° F.) with running pressures about 10-120 psi, 1-5 or 80-90 psi, and a discharge pressure of about 1-5 or about 80-90 psi. Hoshizaki Service Manuel and Kold Draft Cocktail Ice Machines brochure which are both incorporated herein in their entirely purport to make one directionally frozen clear ice cubes without cutting the ice. They both use a lower boiling point R134A refrigerant. In one embodiment the present invention does use a refrigerant with a warmer boiling point, however, the overall quality of the ice is inferior. Moreover, the density of the transparent ice cubes produced in accordance with the invention makes them significantly more dense than the average cloudy non-one directionally frozen ice. This denseness not only contributes to the longevity of the ice when placed in a drink but also requires a specialized approach to cutting the ice into non-spherical shapes.
The present invention addresses this need by employing a cutting mechanism that is tailored to handle density without causing damage to the ice cubes, differentiating it from prior art attempts. It is known in the art that to cut material as hard as brass requires generally a blade that has 7-23 teeth per inch. It depends upon the thickness of the brass being cut. The present invention optimal teeth per inch is 1-4 and cuts ice up to the hardness Moh 3 ice block of one directionally frozen ice without chipping the ice. See as an example The Sennartz Website which is incorporated herein in its entirely by reference.
A configuration of cutting module in an embodiment comprises one or more chromium blades. A chromium blade in the context of the invention is defined as a metal blade comprising sixteen to twenty two percent chromium content and a carbon content of not more than 0.016 percent. One embodiment adds about one to three percent Molybdenum. Besides various codes that govern how food stuff is cut one of ordinary skill in the art knows that blades cannot be made of any material that is harmful to people. As an example a blade having over 22 percent Chromium is brittle and is subject to shattering, which poses a health risk. Occupational exposures and failing metal-on-metal (MoM) hip prostheses both release metal ions cobalt into the body, causing potential health effects like local tissue damage, inflammation (metallosis), and systemic issues such as cardiac problems, neurological symptoms, and organ dysfunction. Therefore, cobalt is not used in blades form cutting ice for human consumption in the United States.
The configuration of the present inventions blade with specific blade thickness, tooth count and material composition, feed cutting rate all are important aspects to mass cut ice into smaller ice cubes without cracking or chipping the ice cubes. Among other advantages, the present inventor has found that use of a steel chromium and carbon blade with less than 6 teeth per inch dissipates heat faster than alternative blades. The dissipation of heat during the cutting process has been found by the present inventor as important for maintaining the integrity of the ice cubes. The steel chromium/carbon blade's rigidity and resistance to flexing and heat dissipation allow for precise cuts without causing chips or cracks, making it an important component of the preferred embodiment to facilitate cutting hundreds of one directionally frozen ice cubes without stopping the blade from spinning to cool the blade. The present invention's blades are not only configured to meet food handling codes they are further configured so they are the only blades that safely mass cuts hundreds of cubes measuring in a range of 1½ to 2½ inches without visible cracks and without visible chips. The blades are superior to other food complaint blades.
The cut rate, or the speed at which the ice passes through the blade, ranges from approximately 60 inches to 180 inches per minute weighing in a range of 20-40 pounds with a preferred rate of about 80 inches per minute. There are no cutting charts for cutting one directionally frozen ice and the present invention teaches a preferred rate. This rate may be adjusted based on the specific conditions of the ice being cut, such as size. In accordance with the performance of the invention, attention is also given to the blade's teeth count, which affects the smoothness and precision of the cut and heat dissipation. The blade in the preferred embodiment features an optimal range of one to four teeth per inch which cuts cubes with no chips in the ice, and most ideally three teeth per inch. One directionally frozen ice has a colder temperature at the bottom of ice than the top of the ice. This temperature difference can be more than 20 degrees F. Therefore, the blades are configured to cut through ice that has the same temperature or layers with different temperatures in the ice. The blade thickness in the preferred embodiment is maintained at about ¼ of an inch or narrower to ensure clean cuts without excessive material removal that could lead to structural weaknesses in the ice. This thickness also dissipates heat faster from the blade than thicker blades. The thicker the blade the more a blade will retain heat. Prior art entitled Sennartz Website, which the pertinent part is incorporated herein by reference in its entirety shows to cut brass which is a Moh hardness 3 and about 130 mm (4.33 inches thick) takes 14 teeth per inch. The thinner the brass the more teeth recommended. The present invention preferred ice cube thickness is about 2 inches by about 2 inches by about 2 inches.
In some embodiments of the invention, multiple blades are utilized. In configurations where multiple blades are utilized, the spacing between the blades is carefully considered. Adequate spacing is necessary to prevent the ice cubes from vibrating excessively, which could lead to cracking or chipping. The spacing further contributes to heat dissipation.
The quality of the ice itself is also a consideration directly associated with the cutting process in accordance with the invention. In the preferred embodiment, the ice cubes have a calcium carbonate content within the critical range of less than 260 milligrams per liter, with lower concentrations preferred of less than 188 milligrams per liter to reduce the risk of cracking or chipping during cutting.
An important feature with vibration is that a heat source (not shown) but known in the art, heats the ambient air temperature to between 50 and 90 ° F. 1 to 5 inches above a top surface of the water during a portion of a freezing cycle. The heat source is the sun, or electric heater, or gas heater, or a heating light, or a furnace or other heating source. One of ordinary skill in the art would know how to supply the aforementioned temperature range between 1 to 5 inches above a top surface of the water during a portion of a freezing cycle from reading this description. If this temperature is colder than about 40 degrees F. 1-5 inches above the water in a cavity, the water will freeze from the top down in addition from the bottom up creating an ice cube that with numerous visible imperfections such as but not limited to crystallization. If the temperature exceeds 90 degrees F., the ice will have visible impurities which would prevent charging a premium price over other ice.
An integral aspect of the preferred embodiment is the stringent adherence to the use of Food Grade or Food Safe materials for all components that come into direct contact with water during the ice-making process. This commitment ensures that the transparent ice cubes produced are not only aesthetically pleasing but also fully compliant with the health and safety standards required for human consumption within the United States.
An embodiment of the invention provides a method to prevent visible crystallization within the center of a transparent ice cube. It involves controlling the water movement pressure within a properly configured ice cavity to prevent the alignment of water molecules into visible crystals as the water transitions from liquid to solid state. An integral aspect of the preferred embodiment is its approach to preventing visible crystallization within the center of a transparent ice cube, a common issue that detracts from the desired aesthetic quality of the ice.
The preferred embodiment addresses the solubility of atmospheric gases, such as nitrogen and oxygen, in water-a factor influenced by the water's temperature and the atmospheric pressure at the air/water interface. Typically, colder water under higher pressure can dissolve more gas, while warmer water under lower pressure dissolves less. In the liquid state, water molecules are in a state of constant motion, but as freezing occurs, these molecules slow down and begin to align in structured formations, leading to crystallization. This system in accordance with the preferred embodiment is designed to maintain constant thermal communication with the ice mold for the duration of the freezing cycle for ice for human consumption and legal sale within the United States. This precise control of water movement from a code compliment agitation device is critical for achieving the high-quality transparency of the ice cubes, as it allows for the consistent and controlled freezing that is essential for preventing the entrapment of air bubbles and other impurities. The refrigeration pipe is maintained contacted with the ice mold ensures that the temperature is evenly distributed across the entire mold surface, leading to a uniform freezing process that is not addressed by the prior art for a system that complies with food codes in the United States. This level of code compliant control distinguishes the present invention from prior art methods by providing a reliable and repeatable process for producing clear ice cubes, free from the cloudiness and structural weaknesses commonly associated with less controlled freezing techniques for ice for human consumption and legal commercial sale in the United States.
The ice mold itself is configured to maintain the water under the necessary pressure conditions, ensuring that the freezing process yields ice cubes with the desired clarity and quality. This controlled environment ensures that water molecules do not align excessively during the freezing process, thereby avoiding the formation of visible crystallization. The invention further employs a method where water droplets are induced to jump at least one eight of an inch to seven inches above the water's surface before landing back in the water, promoting substantially one-directional freezing. In an embodiment comprising a refrigeration (vapor line) pipe 119 that further comprises a refrigerant flowing therein and a substantially flat freezing surface 109 comprising a metal bottom wall of a bin 108, wherein the bin 108 comprises four sidewalls, the mold or a related aspect comprises a removable mold insert 110 having only four sidewalls walls and no bottom. The insert has thermal insulators, with values ranging from 0.1 to 1.5 watts per meter Kelvin (W/(m·K)). It is imperative that the freezing plate has a thickness of 1/16th of an inch to ⅜th of an inch thick with an ideal thickness of about ⅛th of an inch and it is made with a food grade metal having a thermal heat conductivity of 230 and 461 watts per meter Kelvin to make ice pieces or cubes that measure in a range over 1.70 inches by 1.70 inches by 1.70 inches.
A cavity herein inserts into the insert 110. This allows the cavity to be removed from the insert so the ice and cavity is sold together saving the cost of repackaging the clear ice. There is no prior art that fairly suggests an ice maker where the ice is sold in the cavity the ice formed in except for the present invention. Packaging clear ice is different that non-directionally frozen ice. Clear ice requires separating the ice with a divider so when the ice starts to melt and is refrozen the ice will not refreeze together. One of ordinary skill in the art would know how to accomplish this goal from reading this description. A refrigeration pipe 119 generally having a diameter of at least ½ of an inch to 1¼″ and an equivalent length over 25 feet, and most preferably over 66 equivalent length. The removable mold insert 110 is therefore insertable into the bin 108, the four sidewalls of the mold insert 110 and the metal bottom wall 109 of the bin therefore form a cavity which may be placed into another cavity. In one embodiment the cavity is a liner made from a polymer that is formed into a cavity inside the bin. In an exemplary embodiment, the cavity that may be placed within another cavity has four sidewalls and a bottom wall comprising a polymer. The cavity in an embodiment if preformed, meaning it has four walls and bottom wall as opposed to a liner. In an embodiment, a US code compliant non-submersible vibrator 115 is provided for use in ice making or a US code complaint oscillator vibrates or oscillates the water so water droplets nearly all jump at least one eight of an inch and less than seven inches vertically above a top surface of the water and then back into the water, the refrigeration system is configured with refrigeration fittings such as refrigeration fitting 703 as depicted by FIG. 8 that are attached to a segment of the refrigeration system in such a manner so the refrigerant will not leak from the refrigeration pipe throughout a vibration cycle or an oscillation cycle. In one embodiment refrigeration the refrigeration pipe insulator 119D goes over pipe 119 so the freezing temperatures created by the refrigeration pipe does is not subjected to a surface of vibrator 115 that has moving parts therein or behind the surface so the moving parts do not develop frost affecting the amplitude. Insulated refrigeration pipe is known in the art but not known in combination with an offset vibrator so extremely freezing temperature from the pipe does interfere with the waters agitation that creates visible bubbles. The pipe 119 is in thermal communication to the metal bottom wall to maintain the refrigeration pipe in contact with the metal bottom wall throughout a vibration cycle or an oscillation cycle. Vibrator 115 in one embodiment has an internal balance (not shown). The balance (not shown but known in the art) inside 115 is adjusted to increase or decrease the amplitude by increasing or decreasing the offset vibrator to achieve the desired vibration to make visually bubble free ice. Therefore, the offset vibrator 115 has internal moving parts behind an outside surface, a segment of the refrigeration pipe is insulated so a below zero Fahrenheit temperature generated from the segment of the refrigeration pipe does not contact the outside surface of the offset vibrator 115. One of ordinary skill in the art from this description would know how to adjust the balance in offset vibrator 115 so a water droplet jumps ⅛th to less than 7 inches above water in a cavity. In one embodiment a refrigeration pipe 119 contacts and is in thermal communication with the bottom wall of a cavity herein. The offset vibrator is the only vibrator that achieves the amplitude and frequency need to eliminate a visible bubble in ice. The preferred embodiment offset vibrator 115 is attached directly to the substantially flat surface plate 109. One of ordinary skill in the art would know how to accomplish this goal from this description and drawing herein.
Optimizing the freezing time is crucial for producing high-quality transparent ice cubes. The preferred embodiment comprises specific refrigeration pipe lengths, refrigerant types, and compressor BTUs that, in combination with the cavity configuration, achieve the desired freezing time and ice cube quality. The compressors employed in the system are chosen for their ability to deliver a substantial cooling effect, with BTU ratings that typically range from 1,000 to over 3,500 BTUs. Examples of compressors suitable for this purpose in association with embodiments of the invention include the Copeland Scroll Compressor, which is known for its reliability and efficiency in delivering the necessary BTUs for optimal freezing. Another example is the Tecumseh Reciprocating Compressor, which offers a range of BTU outputs to match the required refrigeration needs and is compatible with various types of refrigerant, including low-temperature and cryogenic options. Additionally, the Danfoss Scroll Compressor could be utilized for its precise control capabilities and high performance, ensuring consistent production of clear ice cubes within the desired freezing time frame. This range of 1,000 to over 2,500 BTUs is critical to ensure that the water freezes at a rate that prevents the formation of visible crystallization and air bubbles in association with the preferred embodiment, resulting in the production of high-quality transparent ice cubes. Compressor herein means a compressor assembly known in the art with various other components. The present invention also uses a warmer refrigerant but the ice would is not as superiorly densely frozen which affects the quality and price of the ice.
Reducing fluoride in water provides health benefits. In one embodiment water having fluoride is used. The fluoride then through known methods removed before the water is placed in a cavity herein.
With vibration it is paramount that an ambient air temperature between 40 and 90 degrees Fahrenheit and most preferably 60-75 degrees is in a portion of an area between ½ to 5 inches above a top surface of the water in a cavity herein. This is critical to offset the refrigeration created by a refrigerant having a boiling point of colder than −40° C. The temperature of the refrigerant reaches colder than −40° C. during a portion of a freezing cycle, which is the amount time it takes to totally freeze the ice. The ambient air temperature is accomplished by various means such as not limited to setting of a rooms temperature within the range. An insulated electric heat wire or heated blower or a light, is also subjected to the surface of the ice maintaining this temperature range. All ways to keep this range of an ambient temperature are contemplated and fall into the scope of the present invention. The water is frozen one directionally from only the bottom of the cavity to the towards the top open end of the cavity herein to form multiple ice pieces per freezing cycle. Freezing water from the top down produces an inferior ice piece because the refrigeration pipe is not in thermal contact with the bottom wall of a cavity or is not in thermal contact with a plate the cavity sits atop. Additionally, freezing from the top down requires a flexible mold that stretches to remove the ice from the mold. Lastly, system that freeze water from the top have two compartments. One is an ice cube and the other houses the impurities. The impurities are then removed by various means from the ice cube. See for example prior art entitled Antarctic Clear Ice Maker, which is incorporated herein by reference in its entirety. Page two notes the impurities that require removing. Therefore, not all clear ice machines produce clear ice without crystallization and bubbles without having to manually remove impurities after the ice if formed. The present invention embodiment with a water pump releasing water into a cavity from a reservoir or the vibration embodiment form a piece of ice that requires no need to remove impurities after the ice is formed.
The present invention encompasses all conceivable variations that fall within the scope of the invention.
The preferred embodiment introduces a user-friendly feature that significantly enhances the versatility of the transparent ice machine. It is designed to allow users to efficiently switch out ice molds, thereby enabling the production of transparent ice cubes in a myriad of shapes and sizes. This aspect of the preferred embodiment eliminates the need for tools or the disassembly of any part of the ice maker, which is a marked departure from conventional automatic ice makers that typically require manufacturer intervention for mold changes. The ice molds are designed in accordance with the preferred embodiment to be easily removable from the transparent ice machine without the necessity of detaching any component of the water movement system, which is often integrated within the freezer compartment of a refrigerator.
An additional aspect pertains to the refrigeration system's configuration, specifically the sizing of its components, which in accordance with the vibration or water flow within a cavity it is critical to mass production of cubes that measure 1½ to 2½ inches without having to cut the ice. If these small cubes are frozen to fast or to slow they have visible imperfections. The embodiment incorporates a refrigeration system that is meticulously calibrated in terms of the dimensions and capacities of its piping and compressor to ensure efficient operation. In accordance with an embodiment having vibration or directing water into a cavity during the freezing process, the refrigeration system includes a suction line segment of the refrigeration pipe that is notably sized between one-half and one inch in diameter. This segment extends over 25 feet in equivalent length and is capable of delivering over 1500 British Thermal Units (BTUs). Complementing this, the system features a liquid line segment with a diameter less than ⅜ths of an inch, which is particularly significant given that standard refrigeration piping charts recommend a liquid piping line diameter of three-eighths of an inch for systems providing over 1500 BTUs with equivalent lengths of 25 feet or more for pipes with a diameter of one-half inch or larger. This tailored design in accordance with the preferred embodiment for vibration is not depicted in standard refrigeration line sizing chart in FIG. 28. Further see prior art entitled Hussman Line Refrigeration Guide which is hereby incorporated by reference in its entirety discloses a minimum of a ⅜th inch in diameter liquid line for all piping they disclose. One of ordinary skill in the art would know how to extend a liquid line that measures less than ⅜ths of an inch from an expansion valve by reading this disclosure.
The aforementioned aspects of the invention, along with the detailed descriptions provided, demonstrate the novel and non-obvious nature of the disclosed embodiments, and evidence significant advancements over the prior art in the field of ice cube production. Turning now more specifically to the figures, various aspects of the invention are more particularly presented.

In one embodiment the substantially flat surface 109 does not tilt from side to side or tilt back and forth to make an ice cube herein. A liquid line extending from the expansion valve has a diameter less than ⅜th of an inch.
If the refrigeration pipe were not in thermal communication throughout a vibration or oscillation cycle an air space between the cavity and the pipe would not allow the ice cube to freeze over 1½ of an inch from only the bottom wall of the cavity. Even if the air under the cavity were extremely cold to initially freeze the water, the water in the cavity would warm the air right under the cavity to the degree the ice cube would never freeze over 1½ inch from only the bottom wall of the cavity.

Within the scope of the preferred embodiment, an aspect of the invention is characterized by the incorporation of a vibration mechanism, denoted as vibrator 115, which is securely affixed to a rigid metal plate, referred to as plate 115B.
Referenced in FIG. 2 is the freezing surface 109, which is integrally associated with the refrigeration pipe 119. In the referred embodiment, a vibrator, designated as item 115, is strategically positioned beneath the member plate 119A. The plate serves as a foundational element to maintain the refrigeration pipe 119 in consistent thermal communication with the surface 109, thereby facilitating the freezing process. With respect to making one directionally frozen ice which herein means freezing water in a cavity from only the bottom of the water in a cavity to a top open end of the cavity. It is also imperative that the that the refrigeration pipe 119 is in contact with the plate 119A or directly against a bottom wall of a cavity shown herein. “Contact” means the pipe touches the cavity bottom wall or freezing plate 119A and includes in the definition that a conductive substance is in between the pipe and the cavity bottom wall or plate 119A. The cavity further requires sidewalls that do not allow water to be frozen through the sidewalls which prevents only one directional freezing of the water. The bottom wall must either me of an approved metal that meets codes or is made from a polymer. When made from a polymer the polymer must meet code and have a thickness specific to the polymer to allow freezing water to form an ice cube that measures over 1.70 inches by over 1.70 inches by over 1.70 when coupled with a proper refrigeration system. The ambient air temperature 1-5 inches above the top surface of the water in the cavity must be kept within a temperature range of 40-90 degrees Fahrenheit using the refrigerant boiling point or refrigerant temperature during a portion of a freezing cycle. If not the water would start to freeze from the top down which prevents only one directional freezing from the bottom up.
Member plate 119A is located under refrigeration pipe 119 and therefore refrigeration pipe 119 in one embodiment located between member 119A and freezing surface 109 keeping refrigeration pipe 119 in thermal communication with freezing surface 109 and 119A. Offset vibrator 115 is shown under member 119A which in one embodiment of the preferred embodiment vibrates refrigeration pipe 119, a refrigerant (not shown) inside refrigeration pipe 119 and surface 109 simultaneously. In an embodiment, a vibrator 115 or an oscillator shown herein vibrates or oscillates the water so water droplets jump at least ⅛th of an inch vertically above a top surface and less than seven inches above the water and then back into the water.
FIG. 3 shows transparent ice cube mold 130 made from an inorganic food safe polymer or a thermoplastic good grade polymer having sidewalls 131 and bottom wall 132 having a thickness of less than 0.090 inches or more preferable less than 0.070 inches and most preferably less than 0.040 inches when made out of a polymer. In one embodiment of the present invention bottom wall 132 is substantially smooth without creases. In one embodiment of the present invention, the depth of mold 130 is sufficient so when the stated amplitude is achieved water 133 will not jump outside mold 130 when mold 130 is oscillated and mold 130 is not covered by lid 130A. Transparent ice cube 133A has air bubble molecule 133B which is actually microscopic so it cannot be seen but blown up to see for this disclosure, and center 134C. Text W 134 D is behind transparent ice cube 133A and is clearly visibly void of visible crystallization in the center 134C and center 134C is void of a visible bubble. Handle 135C goes into water 133 as water 133 phase-transforms or is attached to water 133 after it phase-transforms into ice 133A. 135D is a 19 flavor added to water 133. Standard ice cube 140B has crystallization 140C in its center portion. This represents the crystallization found in an ice cube made without one directional freezing. In one embodiment, lid 130A is calibrated to compensate for opposing BTUs and the thickness of the lid is less than 0.040 inches and more preferably less than 0.020 inches where the lid is made from a thermoplastic polymer having a thermal conductivity less than 0.055 watts per meter Kelvin. This allows heat to go through the lid keeping the top surface of the water from freezing before water under the top surface freezes. As shown in one embodiment of the present invention sidewalls 131 is “formed” in the molding process to be about ninety degrees in relationship to bottom wall 132. Another way to explain it is the sidewalls 131 and bottom wall 132 make about an L shape. Sidewalls 131 are smooth and therefore the ice cube (not shown) will have substantially smooth and level sidewalls without cutting as seen with systems that use “liners” for a mold. This mold configuration saves a considerable amount of time in producing a transparent ice cube. In one embodiment of the present invention bottom wall 132 is made out a polymer having a thermal conductivity of more than one hundred watts per meter-Kelvin and a thickness of less than about two inches and stretchable and therefore reusable as it can be pealed from the ice cube (not shown) therein. In one embodiment of the present invention mold 130 is configured without sidewalls 131. In one embodiment of the present invention Lid 130A is hinged to mold 130. In one embodiment mold 130 and lid 130A are used as packaging for smaller ice cubes disclosed herein. Mold 130 keeps smaller ice cubes when warmed and refrozen from sticking together. In one embodiment mold 130 is made out of a fibrous substance. In one embodiment of the present invention sidewalls 131 are packaging dividers to keep ice cubes herein from joining together when warmed and then refrozen. The word “formed” herein means made through a vacuum forming or press process.
FIG. 4 shows impact vibrator 126 having pistons 127. In one embodiment of the present invention, the number of pistons 127 is equal to the number of cavities 128 having water therein (not shown) in ice mold 129. In other words, if there are 100 cavities 128, there are 100 pistons, 127. In one embodiment of the present invention, substantially flat surface freezing surface 109 is located between transparent ice mold 129 and pistons 127. Pistons 127 are configured to hit freezing surface 109 at the exact spot cavities 128 are located above at the exact same time or at different times or to directly impact the bottom of a mold disclosed herein. This provides that the amplitude is delivered to each of the multiple cavities 128 about uniformly. Opening 129A receives pipe 119 in 20 FIG. 2 or a refrigerant (not shown). In one embodiment, vibrator 115 is shown attached to freezing surface 109. In one embodiment, pistons 127 are controlled by a microprocess (not shown) so all the pistons 127 fire at different times. The present invention contemplates all ways to fire pistons 127 at different times or at different forces and all ways fall into the scope of the invention. In one embodiment of the present invention pistons 127 are configured to provide an amplitude to water so a droplet of water jumps above over ⅛th of an inch above the top surface of the water and then back into the water.
FIG. 5 shows bin 120 has cavities 121. Fill source 125 may be configured to add water (not shown) in a continuous water flow to cavities 121 and in one embodiment in a metered dose. Refrigeration pipe 122 is shown configured to turn over 90 degrees as in one embodiment cavities 121 also turns over 90 degrees or more to help release an ice cube (not shown) in cavities 121 without the refrigerant therein leaking. In one embodiment of the present invention, refrigeration pipe 122 is shown under each cavity 121 and is further configured to turn over 90 degrees with inline refrigeration pipe swivel fitting 123. In one embodiment refrigeration swivel fitting 123 is made out of the same material as refrigeration pipe 122. This prevents the corrosion associated with joining two dissimilar material together and that material may be copper, aluminum or other similar material. There are no refrigeration fitting that allow a refrigeration pipe to spin over 15 degrees clockwise or counterclockwise without the refrigerant leaking from the swivel fitting except for the present invention. In combination with a swivel refrigeration fitting a preferred embodiment utilizes a cavity comprising rigid silicone having a Shore hardness harder than 30A.

In one embodiment bottom wall 207 has only one or two or three or four sidewalls 205 and inserts into any cavity shown within this disclosure. In one embodiment bottom wall 207 inserts into another cavity herein so it contacts the bottom wall of another cavity shown within this disclosure. In one embodiment bottom wall 207 has a thickness of 0.070 inches or less 0.040 inches. From position top AB to position bottom BB there is at least a one-degree tapper and most preferably two degrees tapper but less than four degrees tapper. In one embodiment of the present invention, the distance between AB to BB is calibrated to an amplitude so water droplets do not jump outside ice tray 200 when vibrated or oscillated. As an example, and not limitation, if a water droplet jumps four inches the depth from position AB to position BB is over four inches deep. When describing the height of the ice cubes in certain embodiments of the Preferred embodiment the height of the cubes is measured from freezing an ice cube from a bottom position 22 BB to a top position AB within an ice mold such as but not limited to ice mold tray 200.

As depicted in FIG. 8, the preferred embodiment showcases ice molds, designated as item 700, containing water, item 701. These molds are strategically positioned atop a freezing surface, item 702, and are maintained within a close proximity of one half of an inch from the freezing surface, ensuring optimal thermal transfer. A notable feature of this embodiment is the refrigeration pipe, item 703, which is designed with an angular configuration exceeding two degrees, connecting to an elbow refrigeration fitting, item 704. This allows the refrigeration pipe, item 705, to adjust its angle by at least two degrees, and more preferably about forty-five degrees, in either an upward or downward direction relative to elbow 706. This unique configuration, referred to as the “W refrigeration pipe pattern,” is ingeniously crafted to maximize the equivalent length of piping situated between the freezing surface 702 and the bottom structure 707, thereby enhancing the efficiency of the cooling process. In a specific embodiment, the refrigeration pipe 704 is positioned directly beneath the water 701 within the ice mold 700. To ensure the integrity of the system during dynamic operations such as vibration or oscillation cycles, the refrigeration pipe 704 is securely joined to elbow 706 using a brazing technique that incorporates an alloy containing 3% to 15% silver, complemented by a nitrogen flush to establish a leak-proof seal. This meticulous assembly process ensures that the refrigerant does not escape from the refrigeration pipe during the critical freezing cycle. The preferred embodiment provides for two segments of pipe 702, spaced between 1-3 inches apart, which align with the innovative “W configuration” of the refrigeration pipe 703. This arrangement permits a minimal spacing of one inch between pipe segments, contributing to the system's high energy efficiency. In an alternative embodiment, the refrigeration pipe 705 is a continuous element that lies beneath a flat surface without the need for elbow fittings, item 704. By curving the pipe, the preferred embodiment eliminates the necessity for multiple elbow fittings, item 705, thereby streamlining the design for enhanced heat transfer efficiency. The absence of joints in this configuration not only prevents potential refrigerant leakage but also reduces the costs associated with additional fittings and their installation. The present invention encompasses all conceivable methods to achieve these objectives, with each method falling within the scope of the invention. The innovative approach to refrigeration pipe design, as presented in this embodiment, represents a non-obvious advancement in the field, offering a superior solution to the challenges of efficiently freezing water in ice molds.
FIG. 9 shows electric motor 800 having arm 801 attached to cam 803 which when arm 801 spins cam 803 moves arm 804 which moves freezing surface 805 up and down agitating water 806 in ice mold 807. Chop 806A is shown on surface of water 806. In one embodiment, when using ⅜ths inch refrigeration pipe or smaller diameter refrigeration pipe (vapor not liquid line) there are two segments of refrigeration opening 808 under the cavity 807 and water 806 and this provides more piping surface area that allows the water 806 to freeze more uniformly from the bottom of the cavity to the open end of the cavity. Therefore a water pump pumps water 806 from a reservoir (not shown) into a cavity 807 through a water release opening and the two refrigeration piping segments 808 each having a diameter of ⅜ths of an inch or smaller, the bottom wall of cavity 807 measuring less than 2.5 inches by less than 2.5 inches, the two segments of the refrigeration piping are parallel to each other and are under cavity 807 and is in thermal communication with the bottom wall cavity 807. The water 806 is frozen only one directionally from the bottom wall of the cavity towards a top open end of the cavity. The parallel piping under the small cavity 807 allows water in cavity 807 to freeze more uniformly from the bottom of the cavity towards the open end of the cavity as opposed to a single ⅜ths diameter refrigeration pipe and is not known or fairly suggested in the art except for the present invention. See for example FIG. 21 pipe 2103 placement and how the ice 2107 freezes non uniformly. Two pipes under a single cavity freezes the water so the resulted ice piece is denser than using a single refrigeration pipe. A denser ice piece lasts longer in drinks.
There are no clear ice makers that fairly suggest to refrigeration pipes under a single cavity to make a single ice cube that measures less than 2.5 inches by less than 2.5 by less than 2.5 inches except for the present invention.

A specialized thermo-conductive paste, identified as item 1003, is applied either to the top surface of pad 1000 or to the underside, labeled FF, of the freezing surface 1002. This application is not intended to enhance thermo-conductivity but rather to serve as a protective barrier against corrosion that may occur when two dissimilar metals, such as copper pipe 119 and a different material of plate 109, come into contact. The transparent ice cube, item 1004, crafted in this embodiment, is characterized by its lightweight nature, being less than six ounces. The cube, item 1007, exhibits a minimal draft, less than ten percent, and more preferably less than five percent, and optimally less than three percent, from the top position GG to the bottom position XX. The upper portion of the cube, item 1008, maintains a draft of less than five percent, and more desirably less than three percent, from top position FO to top position FT. This precise geometric control is in stark contrast to the standard nontransparent ice cube, item 1009A, which is typically produced without the benefit of one-directional freezing and often contains crystallization, item 1009. In stark contrast, the ice cube produced by the Preferred Embodiment, as evidenced by the center portion 1011 of ice cube 1007, is devoid of any visible crystallization and bubbles, and devoid of dimples showcasing the non-obvious nature of this invention when compared to the prior art. The resulting ice cubes possess a center portion that constitutes at least 85% to 100% of the entire cube, free from visible bubbles, crystallization, cracks, dimples and any cloudiness or milky appearance that could be attributed to high levels of calcium carbonate in the water.

This ice tray exemplifies the versatility of the design, accommodating a multitude of shapes and sizes within a single tray, which is not limited to the examples provided but extends to encompass all conceivable geometric configurations. The transparent ice cube, denoted as item 1204, is crafted to have a draft of less than five percent, with a more preferred specification of less than three percent, and optimally less than two percent, transitioning from top position AZ to bottom position AX. Additionally, the transparent ice cube 1205 is fashioned into the shape of the initial “N,” demonstrating the capability of the preferred embodiment to produce ice cubes in the form of any letter or shape, including but not limited to nonagons, octagons, heptagons, various triangles, parallelograms, rhombuses, squares, pentagons, circles, ovals, hearts, crosses, arrows, cubes, cylinders, stars, crescents, and an array of animal shapes. In a specific embodiment, a food grade water pump, item 1206, is employed within bin 1208, utilizing an inlet pipe 1207 and an outlet pipe 1209, to circulate water and facilitate the formation of ice cube 1008. The bin 1211, which houses the cavity, is equipped with a hinge, item 1211A, ingeniously designed to open and provide an egress for the ice cube. This embodiment allows for the cavity to have a wall that opens, thereby releasing the ice cube. Furthermore, bin 1208 is engineered to tilt, enabling the ice to slide out effortlessly, a feature that underscores the non-obvious innovation of this design. This disclosures clarifies the present invention over previous disclosures and therefore is the most accurate.

FIG. 17 presents a transformative process associated with an embodiment, where a transparent ice cube, item 1700, is segmented into smaller ice cubes, item 1704, by the action of rotating mechanisms, item 1701. These mechanisms are designed to divide the ice cube without inducing visible crystallization or encapsulating visible bubbles within the center, item 1705, of the resulting smaller ice pieces. In a specific embodiment, a heated surface, item 1706, descends upon the transparent ice cube, item 1707, effectuating a division without the traditional sawing motion. This distinctive approach, which may involve heating the mechanism 1701, ensures a smooth and clean separation of the ice cube into smaller fragments, item 1710, each maintaining a pristine center, item 1711, free from imperfections. An embodiment also introduces a saw, item 1709, which is positioned to cut the ice cube either horizontally or vertically. The saw is equipped with a circular blade that features less than 10 teeth per inch and has a slender thickness of approximately ¼ of an inch or less. The blades cut over 1,000 of the smaller ice pieces without having to sharpen or replace the blade. Circular blades dissipate heat faster than other blades increasing the ambient air temperature one directionally frozen ice is cut without thermal shock cracking. Further enhancing the versatility of the system, in embodiments the blade is capable of multidirectional movement, allowing for intricate cutting patterns, including but not limited to five-axis cuts. The arm, item 1712, or a segment of the ice machine, is programmable to automate the cutting process, leveraging a microprocessor to precisely control the blade's trajectory. The present invention contemplates a comprehensive range of configurations and combinations to cut transparent ice effectively, ensuring that the integrity of the ice is preserved during the cutting process. This includes the utilization of artificial intelligence to further automate the production of transparent ice cubes. The saw, item 1709, and the grid, item 1706, are exemplified as potential methods for transforming larger ice cubes into smaller ones, utilizing concentrated streams of water or air to achieve the desired segmentation. The grid 1706 is also capable of handling smaller ice cubes, item 1710, each weighing less than six ounces, and ensuring that all eight sides of the ice cube, item 1713, remain substantially level. In one embodiment, the arm, item 1712, is programmed to extract ice cubes from a bin, such as bin 108 in FIG. 1, or to feed ice cubes into blades, item 2301 in FIG. 23, at a controlled rate of five to fifty feet per minute, with a preference for speeds over ten feet per minute.

In FIG. 18, an embodiment of the invention introduces a series of tooth set configurations for raker blades, each designed to enhance the cutting process in a non-obvious manner when compared to the prior art. The tooth set raker, item 1800, features a three-tooth sequence with a uniform set angle, alternating between left, right, and straight positions. This configuration ensures a balanced cutting action and is suitable for a variety of cutting tasks. The modified raker, item 1802, expands upon this concept with a five or seven-tooth sequence, maintaining a uniform set angle that follows a left, right, left, right, and straight pattern. This arrangement allows for a more nuanced cutting experience, tailored to specific material properties. Further diversifying the blade design, the variable raker, item 1803, presents a tooth sequence that is independent of the tooth pitch and product family, offering a customizable approach to cutting that can be adapted to unique operational requirements. The alternate set in accordance with an embodiment, item 1804, demonstrates a pattern where each tooth is set in an alternating sequence, providing a rhythmic cutting motion that can reduce blade wear and improve the quality of the cut. For applications requiring a more complex cutting pattern in accordance with an embodiment, the wavy set, item 1805, incorporates groups of teeth set to each side within the overall pattern, with varying amounts of set in a controlled manner. This design is particularly effective for reducing vibrations and improving the finish of the cut. The variable set in accordance with an embodiment, item 1806, showcases a blade geometry where the tooth height and set pattern vary according to the product family and pitch. This versatility allows the blade to be fine-tuned for specific cutting applications, enhancing its performance across a range of materials. In the single-level set in accordance with an embodiment, item 1807, the blade geometry is characterized by a single tooth height dimension, requiring each tooth to be bent at the same position with an identical amount of bend. This uniformity is crucial for consistent cutting performance. Lastly, the dual-level set in accordance with an embodiment, item 1808, features a blade geometry with variable tooth height dimensions. The setting of this blade requires each tooth to be bent to variable heights and set magnitudes, enabling the creation of multiple cutting planes and thus facilitating complex cutting tasks.

FIG. 20 shows ice maker 2000 has a substantially flat freezing surface 2011 and a removable lid 2010 provide for an enclosed environment cavity 2007. In one embodiment lid 2010 opens from the top of cavity 2007. In one embodiment, stem 2004 is attached to lid 2010 that covers cavity 2007. When the lid 2010 is in the closed position as shown stem 2004 is submerged in water 2003. When the lid is in the opened position (not shown) the stem is removed from the water. In one embodiment it is critical that water 2003 is removed from the top of an ice cube (not shown) under the water 2003 prior to the ice cube (not shown) being removed from cavity 2007. In one embodiment stem 2004 has gas (air) release opening 2015 that starts out submerged in water 2003 and as the water 2003 freezes the stem 2004 is moved upwards in the water manually or automatically. Persons of ordinary skill in the art would know how to accomplish this goal from reading this disclosure. A lid 2004A in one embodiment covers cavity 2007 or another cavity herein and in one embodiment lid 2004A is configured as an air pump to release gas through opening 2015 and in another embodiment the lid is configured to spin stem 2004. A thermoelectric pad 2013 or refrigeration pipe 2013 having a refrigerant therein is held in thermal communication with substantially flat freezing surface 2011 during a freezing cycle. In one embodiment. Compressor 2008 cools gas or air to less than about 60 degrees Fahrenheit before the gas or air is released into water 2003. Microprocessor 2014 is configured to alert a user when to remove the ice cube from cavity 2007. In the context of the present invention, stem 2004 is ingeniously designed to perform dual functions: it not only spins to create agitation in the water 2003 but also moves vertically up and down. This vertical movement is synchronized with the position of opening 2015, which is an integral part of the stem. As the stem spins, it generates a vortex or stirring effect in the water, enhancing the agitation necessary for the formation of clear ice. The vertical motion of the stem, coupled with the opening 2015, ensures that as the water level decreases due to freezing, the opening remains at an optimal depth to continue effective water movement without introducing air bubbles that could mar the ice's clarity. The present invention's design allows for the incorporation of various components disclosed herein to support the functionality of stem 2004. For instance, a motor or a drive mechanism could be employed to control the rotational and vertical movements of the stem, while sensors could be utilized to monitor the water level and adjust the stem's position accordingly. Additionally, the invention could include a programmable control system to coordinate the stem's movements with the freezing cycle's stages, ensuring consistent agitation throughout the ice-making process. The versatility of the invention is further highlighted by the possibility of using different types of stems and openings, which can be selected based on the specific requirements of the ice mold size, shape, and desired ice clarity. Since stem 2004 is configured to move up and down within the context of embodiments, opening 2015 also correspondingly moves up and down. The spinning or gas (air) moves or agitates water 2003 in accordance with an embodiment. Cavity 2016 is made from food grade material. In one embodiment of the present invention, mechanism 2004A, which may be a gas/air pump or another type of mechanism, is equipped with internal components such as gears, pulleys, or alternative mechanical systems designed to rotate stem 2004, thereby agitating water 2017. The inclusion of such components within lid 2004A exemplifies the versatility of the invention in facilitating the movement of water necessary for the ice-making process. Stem 2004, depicted here for illustrative purposes, can adopt various configurations, including but not limited to designs with a flared end, paddles, or a width greater than its height. The present invention encompasses all possible configurations of stem 2004, with each falling within its scope. The gears, pulleys, and other mechanisms are cited as examples, not as limitations, and the present invention anticipates all conceivable methods for spinning stem 2004.

In one embodiment, water 2103 is vibrated or oscillated at a high intensity amplitude so water droplets 2104 jump at least ⅛th of an inch above water surface 2105. In one embodiment, water 2101 is vibrated or oscillated to create pressure region 2106 and pressure region 2107. The pressure at pressure region 2107 is such that it will not freeze a visible air bubble 2108 at pressure region 2107. In one embodiment the water 2101 is removed from atop cube 2102 before cube 2102 is removed from cavity 2100. The water 2101 on top of cube 2102 is a critical feature for one embodiment of the present invention. Modifications have been made in this disclosure to correct or clarify previously disclosed applications.
FIG. 22 provides a visual representation of an ice cube, designated as item 2200, where the alignment of air molecules, item 2201, leads to the formation of crystallization, item 2204, within the center, item 2203. The preferred embodiment introduces a novel configuration that effectively disrupts this molecular alignment in ice cube 2202, thereby preventing crystallization 2204 within the center 2206 of ice cube 2205. This results in a center, item 2207, that is devoid of visible crystallization 2204, visible air bubbles 2208, and any form of cracking. The preferred embodiment's approach to ice cube production is informed by references such as the CB300X2 Manual, which discusses the removal of water and impurities from the top of the ice block, and US Patent Publication No. 2022/0243971 to Harrell filed on Apr. 22, 2022, which is hereby incorporated by reference in its entirety, and which mentions devices suitable for removing excess water from the mold. The CB300 is not an in machine configured to make ice for human consumption and for legal commercial sale of the ice for human consumption in the United States. It is an ice machine that is configured to make ice for ice carving. These citations underscore the importance of maintaining purity during the freezing process to achieve high-quality ice. In accordance with the preferred embodiment, ice cubes are crafted with a center portion that constitutes between 30-100 percent of the entire cube, free from visible crystallization, cracking, and bubbles and visible dimples. Some embodiments go even further, completely eliminating all such imperfections. The most challenging aspect of ice cube production is attaining this high level of quality in the center of the ice cube. The preferred embodiment achieves this by ensuring that the center portion comprises 100 percent of the ice cube and is 100 percent free from visible crystallization and bubbles, without any milky appearance. This is accomplished through methods such as vibration, oscillation, or the upward release of water into a cavity above within a specific amplitude range.
FIG. 23 shows gang bandsaw/motor 2300 or reciprocal saw that has a motor with moving parts therein (not shown). The motor on the saws herein is made moisture safe by a watertight seam welding, motor encapsulation, Moisture Guard or an IP69k wash down. The present invention contemplates all ways so moisture from cutting the ice and the wet environment will not damage the motor. One of ordinary skill in the art would know how accomplish making the motor moisture resistant motor from this description. A moisture safe motor for bandsaw or circular saw for cutting one directionally frozen transparent ice in combination with the other precise engineering of the present invention is novel. Gang saw motor 2300 has blades 2301 and also blade 2304 that comprise 16 to 22 percent chromium and have 0.005 to 1.6 percent carbon. The gang saw is a bandsaw or circular saw. Blade 2304 is mechanically operated and substantially horizonal and blade 2301 is mechanically operated and is substantially vertical to cut ice cube 2306 into pieces 2307 having a center 2108 that is void of visible crystallization and void of a visible bubble and void of a visible internal crack and void of a visible chip and void of a dimple. Ice cube 2106 is also shown having a substantially level surface and no visible cracking inside the ice cube. Rod 2302 in one embodiment has circular saws 2303. Mechanically operated circular saw blades that spaced less than 3 inches apart on a rod and the rod is configured to move up and down. In one embodiment saws 2303 have a diameter over five inches. Blade 2308 is configured substantially vertically. In one embodiment blade 2308 has a width over three eights of an inch and less than one and one half inch. If the blade has less width is it won't last and if it has more width it will retain more heat. The thickness of blade 2308 is one quarter of an inch or less. A thinner blade will wobble and won't last and a thicker blade will retain too much heat. In one embodiment of the present invention either blade 2308 or blade 2303 have less ten angled teeth per inch with 1-3 teeth being the most preferred tooth count per inch. The less teeth the more space between them and the faster the blades dissipate heat. In one embodiment of the present invention two vertically posited blades 2308 are spaced less than three inches apart. If used with the rod, the rod is configured to keep the blades level and parallel to the ice during and after the ice is cut. If the rod for any reason is moved from the parallel arrangement before, during or after cutting the blades may not cut the ice without visible cracks or visible chips. Blades 2301 are configured to slip off the end of rod 2302 to replace blades 2301. The replacement of blades 2301 is shown by illustration and not limitation as the Present invention contemplates all ways to replace blades 2301 and all ways fall into the scope of the present invention. This includes but not limited to rod 2302 having various threaded sections that when unthreaded releases the blades 2301, snap on, screw on and two piece blades. In one embodiment blades 2301 has a width of one half an inch or more and a thickness of about one quarter of an inch or less. Ring 2303A hold blades 2301 on rod 2302. Ring 2303A are shown by way of example and not limitation as the Present invention contemplates all ways to keep the blades attached and removable from rod 2302 and all ways fall into the scope of the present invention. One embodiment of the ring is threaded and one embodiment of rod 2302 is threaded so ring 2303A screws onto rod 2302 to hold the in place. The ring also keeps blades 2301 from wobbling when they are spinning at over fifty feet per minute. In one embodiment a segment of rod 2302 and blades 2303 are configured to be replaceable. The swivel is shown by way of example and not limitation as Present invention contemplates all ways to move the release opening 2715 from under cavities 2710 to remove an ice cube 2719 from cavities 2710 and all ways fall into the scope of the present invention. One embodiment has a first recirculation non-submersible water pump 2724 that is configured to a first manifold piping 2716 and a second recirculation water pump that is connected to a second manifold piping 2716. In one embodiment release opening 2715 A is configured angled towards a sidewall such that water released upwards into the cavity impacts the sidewall 2700 before impacting the substantially flat surface bottom wall 2709 when the water is released into the cavity. The present inventor has recognized that this aspect helps to reduce a dimple on the underside of an ice cube. Again reference Hoshizaki Service Manuel August 2023. On page nine Hoshizaki release opening is smaller than the opening of the cavity and when it introduces water into a cavity the warmer water contacts the ice forming in the cavity making a huge dimple where the warmer water impacts the center of the ice cube or forming ice piece which is colder than the ice of 32 degrees Fahrenheit. The water is warmer than the ice and will create a dimple where the water contacts the ice unless the water release opening diameter is adjusted for the cavity diameter, which Hoshizaki does not do. The dimple is large enough on a 2 inch cube that ice does not command a premium price over multi-directionally frozen ice. Further, Hoshizaki does not use a combination of a ½ diameter or larger refrigeration pipe that has an equivalent length over 25 feet and extending a liquid line having a diameter less than three eights of an inch from a refrigeration expansion valve. In one embodiment the water release opening extends into the cavity and has a tip that is angled at over a 15 percent angle towards a sidewall of the cavity. One of ordinary skill in the art would know now to extend the release opening into a cavity herein from reading this description. Using multiple water release openings directing water into a single cavity the multiple release openings collectively have a combined diameter that over 30 percent or larger than a diameter of a top opening of the cavity. The preferred each of the multiple release openings have a diameter of 4-12 millimeters.
FIG. 24 shows in one embodiment steps to produce a transparent ice cube.
FIG. 25 shows cavity 2500 having bottom wall 2505 and sidewalls 2504. Water is released into cavity 2505 through a closed 2800 of release stem 2600. Closed end 2800 has multiple water pass through openings 2800A to reduce or eliminate a dimple 2502 in the bottom portion 2503 of forming ice piece 2501 that is caused by water warmer than the ice 2502 impacting the center with dimple 2502. Release end 2900 is configured to spin when water passes through it. The spinning directs the water released to the sidewalls reducing or eliminating a dimple in the ice. 2601 is a release opening that is angles 15 degrees or more toward sidewall 2401A to reduce or eliminate dimple 2502. The present invention contemplates all ways to spin the end of the release opening and all ways fall into the scope of the present invention. Multiple release opening 2600 are configured to release water into a single cavity 2500. The opens together comprise an opening that is within 80 percent of the opening size of 2500 cavity. This prevents a dimple 2500. Screen 2901 is attached to water release stem (opening) 2600 so a water passes through the screen the screen reduces or eliminates dimple 2502. This embodiment further has a refrigeration pipe with a diameter of ½ or larger and a length of 66 equivalent feet, the compressor puts out over 1500 BTUs and a liquid line that measures less than ⅜ths of an inch in diameter where the line is over 13 inches and most preferably 4-6 feet in length. None of these methods in FIG. 25 are disclosed or fairly suggested in the Hoshizaki Service Manuel. The present invention is the only invention that mass produces one directionally frozen ice larger than 1.70 inches by larger than 1.70 inches by larger than 1.70 inches and less than 2.5 inches by less than 2.5 inches by less than 2.5 inches without cutting ice that helps solve the dimple problem except for the present invention. Additionally the release openings such as but not limited to water release opening 2600 are shown extending into cavity 2500. This is paramount to achieving not only the increased density of the present inventions ice but further in reducing or eliminating a visible dimple 2502. Extending a water release opening into a cavity so water is released upwards into the cavity is not fairly suggested in the art except for the present invention and is a notable improvement over prior art.
FIG. 26 shows in one embodiment steps to produce a transparent ice cube.
FIG. 27 depicts a transparent ice maker embodiment 2700A in accordance with an embodiment. Bin 2700 has a bottom wall 2709. In one embodiment bottom wall 2709 is made out of a material having a well-organized crystalline lattice structure and a corrosive penetration rate of less than five mils per year and a thermal conductivity over 14 watts per meter-Kelvin and more preferably over 200 watts per meter-Kelvin and most preferably over 300 watts per meter-Kelvin. Sidewalls 2703 in one embodiment are made out of an amorphous solid material that has a thermal conductivity of less than about 2 watts per meter-Kelvin and more preferably less than 1.7 watts per meter-Kelvin and in one embodiment a corrosive penetration rate of less than five mils per year. In one embodiment sidewall 2703 is about 1 inch thick and more preferably about ½ of an inch thick and most preferably about ¼ of an inch thick providing a distance of about 1 inch, or about ½ of an inch or about ¼ or less between the cavities 2710. In one embodiment bottom wall 2709 is made out of material having over fifteen percent chromium. In one embodiment sidewalls 2703 and bottom wall 2709 are chemically bonded together so they form cavities 2710 that holds water and in one embodiment a watertight seal. The chemical bonding is illustrated by way of example and not limitation as the present invention contemplates all ways to join to materials together so they form a seal or a watertight seal to hold water and all ways fall into the scope of the present invention. The member 2711 holds refrigeration pipe 2702 in thermal communication with bottom wall 2709 is shown by way of example and not limitation as all ways to hold pipe 2702 to bottom wall 2709 is contemplated by the present invention and fall within the scope of the present invention. In one embodiment pump 2721 circulates water 2708 and releases water 2708 through water release opening 2705 upwards into cavities 2710. In one embodiment the water release opening extends into cavity 2710. An embodiment of the invention addresses the issue of intermittent water flow, which traditionally results in the formation of a visible flow line, item 3002, on the ice cube where the water flow has stopped and then restarted. The preferred embodiment overcomes this challenge by ensuring a continuous upward flow into a cavity, thereby eliminating any intermittent flow lines within the ice cube. This continuous flow is essential for achieving the high-quality ice cube characteristic of the preferred embodiment, as it prevents the formation of flow lines that would otherwise indicate intermittent water flow. A pivotal aspect of this embodiment is the non-sprayed release of water into the cavity. The non-sprayed technique is crucial because spraying water into the cavity would not yield the desired quality of ice cube. Therefore, the present invention releases water in a flow compared to a spray. The water is released in a manner that avoids the creation of numerous tiny water droplets in a spray, item 2712, which is fundamental to the integrity of the ice cube's structure. An embodiment may incorporate two or more pumps, item 2721, to facilitate release of water. The release opening item 2705, is presented as an example of the inventive concept, which encompasses all methods of releasing water into the cavities, and these methods are within the scope of the present invention. Notably, bin 2700 is depicted in an inverted orientation compared to bin 108 in FIG. 1, further illustrating the versatility of the design. In one embodiment, the compressor, item 2712, operates within a specific temperature range. The release opening 2705 is sized having a diameter that is over 50 percent of the diameter of the cavity 2710. This reduces the size of the dimple 2710b. In an embodiment the cavity size is sized to freeze a cube 1.70-2.50 inches from a bottom wall of a cavity 2710 or another cavity disclosed herein.
In accordance with an embodiment, a novel approach to ice cube formation is provided, wherein each cavity within a series of cavities is strategically separated by a space containing gas at a temperature of less than 50 degrees Fahrenheit. The present invention uses a refrigerant that has a boiling point colder than −40° C. or a refrigerant outputting a temperature of −40° C. during a portion of a freezing cycle. “C” herein denotes Celius. This specific temperature-controlled environment is instrumental in keeping water in a reservoir colder than 50° C. during a period of time the water is released into the cavity.
In a particular embodiment, the release opening is ingeniously positioned to face a sidewall of the cavity. This orientation ensures that as water is released upward, it first contacts the sidewall, thereby cushioning the impact before the water reaches the bottom wall of the cavity. This method is pivotal in reducing the visible dimpling effect on the ice cube center portion where the water impacts the ice in the cavity, representing a non-obvious solution to a common problem in ice production. Further, the embodiment describes a cavity configuration where the separation between adjacent cavities is defined by the wall thickness of a second cavity, effectively eliminating any air space between them. These walls are constructed from a food-safe, amorphous solid material.
Reservoir 2707 holds water 2708. In one embodiment reservoir 2707 is made from food grade material. One embodiment has two or more release openings 2713 or release pipes 2705 for each of the cavities 2710. In one embodiment the released openings 2713 extend into cavities 2710. In one embodiment the opening tip 2713A is positioned facing sidewalls 2703 so water 2708 hits the sidewalls 2703 before hitting bottom wall 2709. In embodiment water pump 2706 is submersible having an outside surface made of food grade material. The food grade material on the outside of the pump is submerged in water 2708 inside In one embodiment this is important because it reduces the size of a dimple or eliminates the dimple in the ice cubes surfaces where warmer water than the ice cube impacts the partially formed ice cube. Ice cube 2710A shows dimple 2710B from water not shown) impacting in direction 2710C. The present invention contemplates all ways to reduce dimpling and all ways fall into the scope of the present invention. The different sized openings are shown by ways of example and not limitation as the Present invention contemplates all ways to provide about the same amount of water out each release opening 2713 and into cavities 2710. In one embodiment cavities 2710 has a substantially flat surface bottom wall. Regulator 2714 is shown by way of example and not limitation as the Present invention contemplates all ways to keep the temperature regulated in reservoir 2707 such as configuring the refrigeration system and other components together so when water 2708 in the reservoir 2707 contacts bottom wall 2709 water 2708 cools to 70 degrees Fahrenheit and more preferably less than about 60 degrees Fahrenheit in reservoir 2707 and most preferably less than 55 degrees Fahrenheit during a segment of time transparent ice maker 2700 is making ice cube 2719. One embodiment the surface area of bottom wall 2709 inside the sidewalls measures between about 6 to 9 square inches in cavities 2710. In one embodiment reservoir 2707 is configured to hold at least the same water volume as each of the cavities 2710. In one embodiment the transparent ice maker 2700A the superheat is set between 10 degrees Fahrenheit and 40 degrees Fahrenheit and the water released has at least enough pressure to contract the bottom wall 2709 and/or one of the sidewalls 2703. Reservoir 2707 is shown by way of example and not limitation as the. In one embodiment the release openings are sized so about the same amount of water 2708 flows out each release opening or flows into cavities 2710. In one embodiment there are two refrigeration pipes 2702 under bottom wall 2709 of cavities 2710 and in one embodiment they are within an area located between two sidewalls 2703. In one embodiment hot gas (not shown) is run through a refrigeration pipe herein to help release an ice cube from a cavity herein. One of ordinary skill in the art would know how to accomplish this goal from this disclosure. All ice cubes shown within this disclosure may be exchanged with another ice cube shown in other embodiments within this disclosure to create different embodiments. Ice cubes made with this embodiment have a center portion that represents at least 30%-100% of the ice cube and that portion is devoid of visible bubbles, visible crystallizing, visible cracks and visible cloudiness and milkiness. The multiple release openings 2713 or a single release opening are food safe. In one embodiment water pump 2706 is submersible and fits into or hangs on the side of any cavity or bin within this disclosure to agitate water. As the water freezes in the cavity or bin or mold herein the submersible water pump 2706 either is manually periodically moved upwards in the water or is moved periodically upwards automatically. From this description one of ordinary skill in the art will know how to accomplish this goal. In one embodiment reservoir 2707 is filled with water that has a calcium carbonate content less than 180 milligrams per liter of water and a combination of the water and the refrigeration pipe sizes and other components of the ice machine are configured so a portion of the water freezes with an energy efficiency of at least 1 pound of ice cubes per 0.245 kilowatt hours of refrigeration system energy. In one embodiment a water pump shown herein has a segment that touches water that is made of food grade material and in one embodiment of the present invention the water pump is made food safe. In one embodiment bin 108 having five walls made of metal and a lid 114 that provides an internal environment so the ice cube does not reach a temperature where the center of the ice cube cracks from thermal shock when the ice cube is in the bin.
A cavity in an exemplary embodiment comprises a bottom wall comprising a polymer having a thermal conductivity of less than 0.60 watts per meter-Kelvin. The bottom wall and a refrigeration pipe in such embodiment are configured such that the water freezes through the polymer providing that the ice cube extends the over 1¼ inch from the wall of the cavity, and at least a portion of the ice cube comprises a Moh hardness of 1.6 to 4.
A specific embodiment is described where the bottom wall, item 2709, exhibits a thickness ranging from approximately 1/16th of an inch to about ⅜ths of an inch, with the most optimal thickness being about ¼ of an inch. This precise thickness is crucial as it ensures the proper thermal dynamics required for the ice-making process. In this embodiment, the refrigeration pipe, item 2702, is constructed from a material akin to that of the bottom wall 2709, ensuring uniformity in material properties and thermal behavior. Additionally, the pipe 2705 is innovatively transformed into a water manifold, item 2716, equipped with one or more release openings, item 2715. These openings are designed to release water upward into each of the cavities, item 2710, and in certain configurations, there are two or more release ends, item 2715, for each cavity. This manifold system is instrumental in distributing an equal volume of water to each cavity, or at least four of the cavities, thereby promoting consistency in ice cube formation. The space between two adjacent cavities, item 2710, is defined by the thickness of the sidewall, which is meticulously designed to be less than 2 inches, preferably less than 1 inch, and most ideally ½ inch or ¼ inch or less. The proximity of the cavities enhances energy efficiency during the freezing process. In one embodiment, the space between the cavities, as depicted in FIG. 7, contains air with a temperature ranging from 35-85 degrees Fahrenheit. However, for optimal results, the air temperature is maintained as close to 35 degrees Fahrenheit as possible. This temperature control significantly contributes to the reduction of dimpling on the underside of the ice cube. The embodiment further details that the ice cube produced possesses a center portion that constitutes 85 percent of the ice cube, which is substantially free from visible crystallization, cracking, clear bubbles, and any cloudiness or milkiness. In another embodiment, the entire ice cube is completely devoid of these imperfections. Moreover, a cavity within this embodiment is crafted from a substantially flat liner made of food-grade or food-safe material. This liner, when placed in a bin or a larger cavity as shown herein, forms the cavity that is essential for the one-directional freezing of water. It is this one-directional freezing that is pivotal for the creation of quality transparent ice cubes, a materially significant departure from the teachings of the prior art. Therefore, one or more release opening combined or individually have a diameter over 30 percent of a top opening diameter of the cavity.
In one embodiment an expansion valve in FIG. 1 is incorporated into 2700A. In one embodiment a compressor or water pump 2706 is configured to be water cooled. In one embodiment compressor 2706 is either a scroll or reciprocating compressor. In one embodiment compressor 2706 is configured to cool air or a gas to about 60 degrees F. 2709A is a sideview of one embodiment of bottom wall 2709 having recesses 2717 sized to receive sidewalls 2703. In one embodiment the sidewalls 2703 and bottom wall are further joined together with a weld, or chemical bond or screw to create a leak resistant or leak proof seal between the materials. The joining of two materials together to form a watertight seal is shown by way of example and not limitation as the Present invention contemplates all ways to join two of the same materials together or the joining of two dissimilar together to form a watertight seal and all ways fall into the scope of the present invention. In one embodiment a solid or liquid gasket (not shown) in placed inside recess 2717. In one embodiment sidewalls 2703 are formed together in an injection modeling process and with a screw (not shown) is screwed to wall 2709. Preferably the screw is the same material as wall 2709 or the screw is made from a polymer to reduce or prevent corrosion when two dissimilar material contact each other. In one embodiment reservoir 2707 is configured to have more interior volume than all of cavities 2710. In In one embodiment release opening 2713 has a diameter of over ⅛th of an inch and more preferably over ⅜ths of an inch in diameter or larger. Ice cube 2719 has a solid center portion 2720 that is devoid of a visible bubble and devoid of visible crystallization and devoid of visible cracking and devoid of cloudiness. In one embodiment center portion 2720 is at least 30 percent the ice cube 271. In some specific embodiments, the center portion 2720 is at least 70-85 percent of the ice cube 2719. In some even more specific embodiments, the center portion 2720 is at least 98 percent of the ice cube 2719. In some very specific embodiments, the center portion 2720 is 100 percent of the ice cube 2719, In embodiment ice cube 2710 or any ice cube of the preferred embodiment disclosed herein has a calcium carbonate content less than 260 milligrams per liter of the water, more preferable less than 260 milligrams per liter of the water and most preferably less than 80 milligrams per liter of the water. A high concentration of calcium carbonate creates a visible milky appearance (cloudiness). In one embodiment there are two or more rows of cavities 2710 such as seen for example in FIG. 1. In one for most efficiency the water in the reservoir is chilled below 40 degrees in the reservoir. This helps in transferring thermal conductivity to the water reducing further energy consumption and achieves an energy efficiency of at least 1 pound of ice cubes per 0.245 kilowatt hours of refrigeration energy. One embodiment has pressure cut in/cut out 2718 and the pressure differential is set at less than about 100 pounds. In one embodiment refrigeration pipe 2702 or pipe 703 as seen in FIG. 8 has at least three or more segments 20 inches long that are parallel to each other and they are spaced between 1 inch to 3 inches apart. The term “refrigeration energy” herein means the electrical energy consumed by compressor 2706. In one embodiment during a segment of the freezing process water 2708 contact the sidewalls 2703 before bottom wall 2709. Refrigeration system energy means energy to freeze ice. In one embodiment ice cube 2719 weighs between about 2.5 and 5.5 ounces and in other embodiment 10 pounds. In one embodiment ice cubes 2719 extends downward from bottom wall 2709 between 1¼ to 3 inches. In one embodiment transparent ice maker 2700A is further configured to have a superheat between 5 and 40 degrees Fahrenheit during a segment of time it is operating. In one embodiment refrigeration pipe 2702 has a square, round, oblong, oval or a rectangular shape diameter. Non-round piping allows more surface area of the pipe to contact a freezing plate or bottom wall of a cavity. This further reduces the energy consumption as it provides better heat transfer which is important to making clear large cubes as opposed to multidirectional frozen cubes. Most ice makers use ⅜ths inch refrigeration pipe. As an example and not limitation to make 2 inches cubed clear ice a refrigeration pipe due to its round shape less than a 1/16th of an inch of the pipe contacts the underside of a 2 inch cavity bottom to make a 2 inch cube. By having a rectangular shape the refrigeration pipe will cover the entire bottom of the cavity. This provides more efficient heat transfer and allows the water to freeze about uniform which results in a more appealing ice piece. The other shapes mentioned above also provide better heat transfer than a round diameter pipe.
As shown pipe 2702 is formed with fittings such as but not limited to an elbow fitting (not shown). Fittings will not allow pipe 2702 to lay against a substantially flat surface shown within this disclosure. It is advantageous in one embodiment that no fittings are used under a substantially flat surface herein. This goal is accomplished in one embodiment by forming the piping without fittings under the substantially flat surface. In one embodiment ice cube 2719 has either 8 sides, is round, square, spherical rectangular, in the shape of a numeral or a letter of the alphabet or another shape. See FIG. 12 for additional shapes. In one embodiment refrigeration pipe 2702A is positioned in alignment under cavities 2710 so two, three, four or more segments of the refrigeration pipe 2702A are at least 24 inches long and parallel to each other and they are spaced between 2 inch to 4 inches apart between space 2727. Pipe 2702A is curved and without refrigeration fittings. A refrigeration pipe fits into a refrigeration fitting such as seen in FIG. 7 where pipe 703 fits into elbow fitting 706 forms a ridge keeping the refrigeration pipe 703 from being in thermal communication with a substantially flat surface herein. 2702A is configured to stay in thermal communication with a substantially flat surface herein because in one embodiment 2702A is curved using no refrigeration fittings under the substantial flat surface. The curved pipe is shown by way of example and not limitation. The Present invention contemplates all ways to keep a refrigeration pipe in contact communication with a flat surface throughout a vibration or oscillation cycle and all ways fall into the scope of the present invention. In one embodiment a refrigeration pipe 2702A that has at least four radii 2723 each having about a 180 degree radius, the radius provides for a distance of 2 to 4 inches between segments 2727 of the refrigeration pipe, and the refrigeration pipe contacts the substantially flat surface are there are no refrigeration fittings in contact with the substantially flat surface. In one embodiment refrigeration pipe 2702 is shown in alignment under the cavities 2710 and within the sidewalls. One embodiment has an invisible air component that surrounds the entire transparent ice maker embodiment 2700 A or a segment of transparent ice maker embodiment 2700 A and the air temperature is configured between 40 degrees Fahrenheit and 85 degrees Fahrenheit during a segment of time the transparent ice maker embodiment 2700 A is operating and more preferably about 70 degrees Fahrenheit. In one embodiment release opening 2715 is positioned so when water 2708 is released it impacts sidewall 2703 at about position 2700 so water 2708 first impacts the sidewall 2703 before hitting the bottom wall 27.09 when water 2708 is first introduced into cavities 2710. In this embodiment the cavities are 1 or more inches longer than the height of the ice cubes 2719 and more preferably at least 1-4 inches longer than the height of ice cubes 2719. Position 2700 is not to scale and only is meant to depict that water 2708 first hits the sidewall 2703 in one embodiment. In one embodiment wall 2709 is configured not to tilt back and forth or from side to side. In one embodiment the space between two of the cavities 2710 is the thickness of the sidewall 2703. A cavity as shown in FIG. 7 ice tray 200 has five walls and is configured to insert into of the cavities disclosed herein and in one embodiment one of the cavities 2710. In one embodiment the water flow out release opening 2715 can be increased or decreased by as an example and not limitation an adjustable version of recirculation pump 2706. In one embodiment the water 2708 in reservoir 2707 has a concentration of less than 180 milligrams per liter of 40 calcium carbonate at the after the ice cube 2719 is formed in cavities 2710. In one embodiment when water 2708 is released into cavities 2710 the bottom wall 2709 has a temperature above freezing. In one embodiment bottom wall 2709 is above a freezing temperature when water 2708 first contacts it. In one embodiment release opening 2715 is sized to be substantially the same size as cavities 2710. This reduces indented area in the bottom of an ice cube where warmer than freezing water 2708 releases upwards and contacts the ice cube. Transparent ice cube 2719 is generally frozen from bottom wall 2709 extending outward about 1½ and less than 2½. In one embodiment sidewalls of ice cube 2719 from position CD to DC has a draft less than about 3 percent and more preferably less than about 2 percent. It is further understood that refrigeration pipe 2702 has segments that are insulated. Utilizing water to minimize calcium carbonate concentration further improves energy efficiency, for example, such as by using water that contains no greater than 180 milligrams per liter calcium carbonate, no greater than 90 milligrams per liter, no greater than 45 milligrams per liter, or no greater than 20 milligrams per liter. mold insert 110 in FIG. 1 like all embodiments shown in other figures is used in one embodiment of this embodiment. Molds and cavities shown herein are used in one or more embodiments within this disclosure. The combination of both a non-spraying release of water upwards into a cavity combined with a reduced calcium carbonate concentration synergistically combines to improve energy efficiency and ice cube esthetics. Further, high amounts of calcium carbonate create a “cloudy” or “milky” look to a clear ice cube. In one embodiment the cavity is separated by a second cavity by the wall thickness of the cavity having no air space in between. In one embodiment water is released upwards in a non-sprayed fashion into a cavity and in a continuous water flow, and an attachment of the refrigeration pipe to a substantially flat surface is such that the pipe stays in thermal communication with the substantially flat surface during a freezing cycle. In one embodiment a cavity is separated by a wall thickness of a second cavity providing no air space between the cavity and the second cavity. In an embodiment wall is food safe and is made from an amorphous solid material having a thermal conductivity of less than 2 watts per meter-Kelvin. In an embodiment, the space between cavities, as depicted in other figures within this disclosure, is controlled with air at a temperature ranging from 35-85 degrees Fahrenheit. More preferably, the air temperature is maintained at less than 50 degrees Fahrenheit. This temperature regulation significantly contributes to the reduction of dimpling on the ice cube surface, enhancing the aesthetic and structural quality of the final product. In a specific embodiment, the construction of the cavities is such that one cavity is delineated from an adjacent cavity by the wall thickness of the second cavity, effectively eliminating any air space between them. This wall is composed of a food-safe amorphous solid material with a thermal conductivity of less than 2 watts per meter-Kelvin. The wall's thickness, in conjunction with a substantially flat surface, forms a seam. This seam is ingeniously designed to provide a seal, and in certain implementations, it achieves a watertight seal, which is critical for maintaining the integrity of the ice during the freezing process. Furthermore, an embodiment includes a first release opening and a second release opening. The first release opening is configured to release water upward into only one cavity in a non-sprayed manner, while the second release opening is similarly designed to release water into a second cavity. This targeted release of water is pivotal for freezing a portion of the water with an energy efficiency of at least 1 pound of ice cubes per 0.245 kilowatt hours of refrigeration system energy. The ice cube formation extends outward over 1.5 inch from the bottom wall of the cavity, demonstrating the efficiency and precision of this method. The provision of a dedicated release opening for each cavity, or approximately each cavity, ensures highly efficient freezing. This design ensures that the ice cubes are uniform in size because each cavity receives approximately the same amount of water at about the same time. This aspect addresses the challenge of achieving consistency in ice cube size and quality, which is not described in the prior art. In an exemplary embodiment, a first release opening 2715 is configured to direct water upwards into only one cavity 2710 in a non-sprayed manner and a second release opening 2715 directs water upwards into only a second cavity 2710 so there is one release opening 2715 for each cavity 2710. Extending the water release opening into a cavity is not fairly suggested in the art except for the present invention. This ensures water from the water release opening enters a single cavity and coupled with a water release opening sized having a diameter that is 30 percent of the diameter of the opening of the cavity results in large pieces with a reduced dimple size.
It is important to note that the components depicted in the figures throughout this disclosure, including the ice cubes themselves, are designed with interchangeability in mind. This flexibility allows for the various components from different embodiments to be combined, creating new and distinct embodiments within the scope of the present invention.
