Artisan Ice System, Method and Apparatus

Abstract

In a system for production of artisan ice, a freezer receives an artisan ice production unit comprising a water bath, a mold bottom and a mold top. The mold bottom and top define a mold that is partially immersed in the water bath when the water bath and mold are engaged and filled with water. The water bath may be heated by a heat source to control freezing of the water in the mold. The water bath, and mold top define lips above the level of water in the mold to prevent leakage of water from the mold and water bath. The mold bottoms may be stacked when the mold bottoms contain artisan ice portions for compact storage of the artisan ice portions.

Description

I. BACKGROUND OF THE INVENTION

A. Field of the Invention

The Invention is a system for commercial production and storage of artisan ice, as defined below, and a method for the production and storage of artisan ice. The Invention also is an apparatus for production of artisan ice.

B. Statement of the Related Art

‘Clear ice’ is water ice that is substantially free of trapped gas bubbles or suspended particulate matter. As a result, clear ice is substantially transparent. In clear ice production, water freezes in a single direction. Freezing the water in a single direction allows gas bubbles and suspended particulate matter that are forced from solution during freezing to move ahead of the advancing ice so that the gas bubbles and particulate matter are not trapped by the ice.

Conventional clear ice production may utilize a cascade of water over the face of the freezing ice to wash gas bubbles and particulate matter from the ice. This technology can produce clear ice cubes of up to 1.25 inches on a side, which is a limitation of the water-cascade technology. Alternatively, conventional clear ice production may use mechanical mixing to strip the gas bubbles and particulate matter from the face of the freezing ice. This technology is suitable for producing large blocks of clear ice. Conventional clear ice production systems are not flexible as to the size or shape of the clear ice produced.

‘Artisan ice’ is a single-serving portion of clear ice that is larger than the 1.25 inch prior art technological limit for commercial production of single serving portions of conventional clear ice. Artisan ice is generally in the shape of a sphere of about 2.5 inches in diameter or of a cube about 2.5 inches on a side. Artisan ice is sized so that only a single portion of artisan ice will fit within a conventional drinking glass. Artisan ice is sought after to serve patrons of bars, nightclubs and restaurants. Patrons find artisan ice to be attractive and desirable and to justify the premium price for a beverage served with the artisan ice. When used to chill a beverage in a drinking glass, the large size and relatively small surface area of a portion of artisan ice results in longer life, slower melting and less dilution of the beverage than is the case for smaller pieces of conventional clear ice.

The problem of commercial production of artisan ice has not been solved using the conventional technologies of the water cascade or mechanical mixing. A common prior art strategy to produce artisan ice is to cut a large block of clear ice into smaller portions of clear ice using a band saw and then to mold the smaller portions into spheres or other shapes using a hand-operated mold or to manually carve the artisan ice using cutting tools. This process of hand shaping each individual portion of artisan ice is labor and energy intensive and hence expensive and not suitable for a commercial environment.

Damage to the artisan ice after it is created also is important to the commercial production of artisan ice. Artisan ice portions that are cracked or chipped are considered undesirable by patrons.

Efforts have been made to allow consumers to produce small quantities of artisan ice for personal use by retarding the rate of freezing of water in a mold and by controlling the direction of freezing. The consumer systems present issues of timing and storage of the artisan ice. In a typical clear ice system for personal use, the shaped clear ice must be removed from the molds in a narrow window of time. Otherwise, the shaped clear ice will freeze to the molds and be difficult to remove. The storage issue is that if two portions of ice are placed in contact with each other, the two portions of ice will tend to freeze together. The merging of the two portions is due to fluctuating temperature within the freezer and also due to pressure effects—the increased pressure of a portion of ice bearing on another reduces the freezing temperature of the water at the point of contact and melting the ice at the point of contact. The subsequent re-freezing of the water at the point of contact welds the two pieces of ice together.

What is needed is an artisan ice production system that can be used in a commercial environment such as a bar or restaurant, that allows ready removal of artisan ice portions from the molds, and that allows storage of the artisan ice portions without artisan ice portions contacting one another and without damage to the artisan ice portions. The prior art does not teach the apparatus, system and method of the Invention.

II. BRIEF DESCRIPTION OF THE INVENTION

In the system of the Invention, a commercial upright freezer includes insulated walls and a door. The air within the freezer is cooled to below the freezing temperature of water by any conventional refrigeration system, such as Carnot cycle refrigeration. The freezer may be divided into a production portion and a storage portion. The production portion is for the purpose of freezing water into artisan ice portions. The storage portion is for storing the frozen artisan ice portions for use. The production and storage portions may be one and the same.

The production portion of the freezer includes a plurality of surfaces. Each of the surfaces is configured to support a single artisan ice production unit. Each surface includes a heat source configured to heat all or a part of the surface on which the artisan ice production unit will reside. Each heat source may be any heat-producing or heat transfer apparatus, such as an electrical resistance heater or a Peltier device.

The commercial freezer includes a control system to control the air temperature within the freezer, to control whether any or all heat sources are activated, and to control the amount of heat generated by each heat source. The commercial freezer may include sensors to inform the control system of the air temperature and the temperature of one or more of the heat sources. A sensor connected to the control system may be embedded in the water bath, mold bottom, or mold top.

The system of the Invention includes at least one artisan ice production unit. The artisan ice production unit is configured to be supported within the freezer by one of the surfaces of the production portion of the freezer. Each artisan ice production unit includes three components: a water bath, a mold bottom and a mold top. The mold bottom and mold top cooperate to define a mold.

As used in this document, the term ‘artisan ice portion’ is the single-serving piece of clear ice produced by the freezing of water in the mold. The mold defines the shape of the artisan ice portion. The mold top and bottom may be hemispherical to produce a spherical artisan ice portion. The mold top and bottom may define a plurality of the same shapes, for example eight shapes, so that a plurality of artisan ice portions will be produced at one time. The shapes defined by the mold top and mold bottom may be the same for the plurality of shapes or they may be different. For example, a single combination of a mold top and a mold bottom may define both spheres and cubes. The shape defined by the mold is not limited to spheres and cubes and the shape of the resulting artisan ice portion can be any three-dimensional solid, provided that the artisan ice portion can be released from the mold without damage to the artisan ice portion or to the mold.

The water bath is an open-top, watertight tray configured to receive and to support the mold bottom. When the water bath contains water and the mold bottom is supported by the water bath, at least a portion of the mold bottom is submerged in the water contained in the water bath. The watertight tray may define a plurality of chambers, with each chamber corresponding to one of the shapes defined by the plurality of shapes of the mold bottom. Alternatively, the watertight tray of the water bath may define a single reservoir.

The water bath defines a water bath lip about the periphery of the water bath. The mold top both defines a mold top lip around the periphery of the mold top. The water bath and mold bath lips are upstanding and extend upward to a lip level, which is above the level of water in the mold when the mold and water bath are filled with water. When assembled, the mold top lip fits within and mates with the water bath lip. This arrangement avoids the need to make the joints watertight between the water bath, mold bottom and mold top and avoids water leaking from the mold when the mold is filled.

The mold top defines a water fill hole at the top of the top of each mold top. The water fill hole is surrounded by a fill lip, which also extends in the upward direction to or above the lip level. The fill lip catches overflow or spillage of water from the mold and acts as a water level indicator—when water extends from the mold into the volume defined by the fill lip, the mold is completely filled.

In use, the mold top and water bath are releasably attached to the mold bottom by a clip to define the assembled artisan ice production unit. The mold bottom may define the clip. Clipping the mold top and water bath together prevents the mold top from floating when the artisan ice production unit is filled with water. The water-filled artisan ice production unit is placed in the production portion of the freezer, with the water bath in contact with a heat source. At least a portion of the mold bottom is submerged in the water of the water bath. The mold bottom defines a perforation below the level of water within the water bath so that the water within the mold is in communication with the water in the water bath.

The cold air within the freezer chills the mold top. The mold top is un-insulated and heat moves across the walls of the mold top from the water in the mold to the cold air of the freezer. The chilled water adjacent to the mold top begins to freeze. Gas within the freezing water is forced from solution, along with dissolved solids. The water in the mold freezes from the top downward, with the growing ice forcing dissolved gas and solids out of solution and driving the resulting gas bubbles and suspended solids before it. When the gas bubbles and suspended solids reach the perforations, the gas and solids are expelled from the mold and are not incorporated into the clear ice of the artisan ice portion.

The water bath acts as a heat reservoir, warming the mold bottom and defining the temperature gradient through the mold from top to bottom. The water bath thus controls the rate of freezing of water within the mold. The heat source provides additional heat to the water in the water bath as necessary to control the rate of freezing of the water in the mold. The water bath buffers heat from the heat source to provide even heat transfer to the mold bottom. The combination of the water bath and the heat source, all under the control of the control system, provides an adequately slow rate of freezing for the water in the mold so that the advancing ice does not overtake the gas bubbles and suspended solids. As a result, the ice remains clear. The control of the temperature gradient across the mold allows the highest rate of freezing possible consistent with the production of clear ice.

When the water within the mold is frozen to define an artisan ice portions, a user may remove the artisan ice production unit from the freezer and remove the mold top and water bath. The user will leave the artisan ice portions in the mold bottom and place the mold bottom and artisan ice portions in the storage portion of the freezer, ready for use. Leaving the artisan ice portions in the mold bottom segregates the artisan ice portions from one another, avoiding damage to the artisan ice portions by cracking or by welding the artisan ice portions one to the other. The mold bottom and artisan ice portions combination may be stacked, allowing compact storage of the artisan ice portions.

The method of the Invention is the use of the system of the Invention to produce artisan ice portions. The apparatus of the Invention is addressed to the artisan ice production unit.

IV. DESCRIPTION OF AN EMBODIMENT

The artisan ice production system 2 includes a freezer 4, shown by FIGS. 1, 2 and 3. FIG. 1 is a front view of the freezer 4. FIG. 2 is a side sectional view of the freezer 4. FIG. 3 is a perspective of the outside of the freezer 4.

From FIGS. 1, 2 and 3, the freezer 4 includes insulated walls 6 and a door (not shown) to define a closed interior 8 of the freezer 4. The freezer 4 defines an ice production portion 10 and an ice storage portion 12. The ice production and storage portions 10, 12 may be one and the same. Air 14 on the interior 8 of the freezer 4 is chilled conventionally to below the freezing temperature of water.

Artisan ice production units 16 are filled with water 18. A user slides he artisan ice production unit 16 into the ice production portion 10 of the freezer 4, as shown by FIGS. 1 and 2. The artisan ice production unit 16 is supported within the freezer 4 by a surface 20, which may be a shelf. The surface 20 includes a heat source 22. Sensors 26 inform a control system 24 as to the temperature of the heat source 22 and the temperature of the air 14 within the production portion 10. The system 2 may include as many sensors 26 as required by the control system 24 to closely control the rate of freezing of the water 18 in the artisan ice production unit 16. Sensors 26 may be included to detect the temperature of the chilled air 14, the temperature of the heat source 2, and any other parameters that may be useful to the control system 24 to control the rate of freezing of the water in the artisan ice production unit 16. Sensors may be imbedded in the artisan ice production units 16.

FIGS. 4 and 5 are exploded views and FIG. 6 is a sectional view of the assembled artisan ice production unit 16. The artisan ice production unit 16 includes a water bath 28 and a mold 30. The mold 30 comprises a mold top 32 and a mold bottom 34. The mold 30 defines the shape 36 of the artisan ice portion 38. In the examples of FIGS. 1, 2, 4-8, and 10, the shape 36 is a sphere. The shape 36 may be any three-dimensional form where the resulting artisan ice portion 38 can be released from the mold top 32 and mold bottom 34 without damage to the artisan ice portion 38 or to the mold 30. Example suitable shapes 36 include a sphere, cube, and rectangular solid, but many other shapes 36 may be used.

As shown by FIGS. 4-6 and 9, the water bath 28 defines one or more water reservoirs 40. In the examples shown, the water bath 28 defines a separate water reservoir 40 for each of the shapes 36 defined by the mold top and bottom 32, 34. Alternatively, the water bath 28 may define a single water reservoir 40 configured to receive all of the shapes 36 defined by the mold top and bottom 32, 34. The water bath 28 also may incorporate more than one reservoir 40 but fewer reservoirs 40 than the number of shapes 36 defined by the mold top and bottom 32, 34. The reservoirs 40 are in thermal communication with the heat source 22 when the artisan ice production unit 16 is on the support 20 in the production portion 10 of the freezer 4. In the example of FIG. 6, the heat source 22 warms a heat transfer plate 44 that in turn selectably warms the water 18 in the water bath 28.

From FIG. 6, when the mold 30 and water bath 28 are filled with water 18, the wall of the mold bottom 34 is in contact with the water 18 in water bath 28. The water 18 within the mold 30 therefore is in thermal communication with the water 18 in the water bath 28 through the wall of the mold bottom 34. The mold top 32 is exposed to the chilled air 14 in the freezer 4. The water 18 in the mold 30 therefore is in thermal communication with the chilled air 14 in the freezer 4 through the mold top 32. Neither the mold bottom 34 nor the mold top 32 is insulated.

When the artisan ice production unit 16 is filled with water 18 and is located within the freezer 4, heat flows from the relatively warm water 18 inside the mold 30 through the mold top 32 to the chilled air 14. The heat flow from the mold 30 is indicated by arrow ‘A’ on FIG. 6. As the water 18 inside the mold 30 cools and begins to freeze, heat flows from the relatively warm water 18 in the reservoir 40 through the mold bottom 34 into the relatively cool water 18 in the mold 30, indicated by arrow ‘B’ of FIG. 6. The flow of heat from the reservoir 40 to the mold 30 controls the temperature gradient in the mold 30 and hence the rate of freezing of the water 18 in the mold 30. The reservoir 40 and mold bottom 34 are configured so that the rate of heat transfer through the mold bottom 34 is such that the rate of freezing of water 18 in the mold 30 is adequately slow so that gas bubbles and suspended particulate matter forced from solution by the advancing ice are not trapped in the ice and continue to move in advance of the ice. As heat flows from the reservoir 40 to the mold 30 and from the mold 30 to the chilled air 14, the water 18 in the reservoir 40 cools. As the water 18 in the reservoir 40 cools, the transfer of heat from the reservoir 40 to the mold 30 slows and the reservoir 40 loses its control authority over the freezing of water 18 in the mold 30. The control system 24, informed by the sensors 26, then commands the heat source 22 to warm the water 18 in the reservoir 40, restoring heat available for transfer from the reservoir 40 to the mold 30 and restoring the control authority of the reservoir 40 over the rate of freezing of water 18 in the mold 30. The flow of supplemental heat from the heat source 22 to the mold 30 is indicated by arrow ‘C’ of FIG. 6. The water 18 in the reservoir 40 buffers and smooths the flow of heat from the heat source 22 to the water 18 in the mold 30

From FIGS. 6 and 7, the mold bottom 34 includes a perforation 42 so that the water 18 in the mold 30 communicates with the water 18 in the reservoir 40. When the clear ice freezing in the mold 30 reaches the bottom of the mold bottom 34, the gas bubbles and suspended particulate matter are expelled from the mold 30 through the perforation 42 and are not incorporated into the artisan ice portion 38.

As shown by FIGS. 6-9, the artisan ice production unit 16 includes features that prevent the artisan ice production unit 16 from leaking when filled with water 18 even thought the joints between the water bath 28, mold bottom 34 and mold top 32 are not watertight. The first of those features is an upstanding water bath lip 44 that is defined by a periphery 46 of the water bath 28, best illustrated by FIG. 9. The water bath 28 defines a watertight tray that will contain water 18 without leakage up to a lip level 48, shown by FIGS. 6 and 9. The lip level 48 is above the level of water 18 in the mold 30 when the artisan ice production unit 16 is filled with water 18. The mold bottom 34 does not define a lip and is submerged in water 18 when the artisan ice production unit 16 is filled with water 18.

The mold top 32 defines a mold top lip 50 defined by the periphery of the mold top 32. The mold top lip 50 extends upward to or above the lip level 48 and prevents water 18 overflowing an over-filled water bath 28 from flooding the mold top 32. The use of the water bath lip 44 and the mold top lip 50 that extend above the water level of the mold 30 also provides that none of the joints between the water bath 28, mold top 32 and mold bottom 34 need be watertight. Watertight joints are not required to prevent water 18 leakage from the mold 30 or water bath 28.

The water bath 28 and mold top 32 must be selectably attached together to prevent the mold top 32 from floating on the water bath 28 when the artisan ice production unit 16 is filled with water 18. As shown by FIG. 4, the mold bottom 34 defines a clip 58. The mold top 32 defines a mold top latch 60 and the water bath 28 defines a water bath latch 62. When the artisan ice production unit 16 is assembled, the clip 58 engages both the mold top latch 60 and water bath latch 62, securing the artisan ice production unit 16 in the assembled condition and preventing the mold top 32 from floating on the water bath 28.

Although watertight joints are not required, it is desirable to prevent adjacent artisan ice portions 38 in adjacent molds 30 from freezing together. The mating surfaces of the mold top 32 and mold bottom 34 may feature mating crenellations 52 to prevent ice bridging between adjacent molds 30, as shown by FIG. 6.

The mold 30 may be filled through a fill hole 54 (FIGS. 6 and 8). The filling process may be either manual by a human operator or may be automatic. A fill lip 56 may surround the fill hole 54. The fill lip 56 also extends upward to the lip level 48, just as the water bath lip 44 and the mold top lip 50. The fill lip 56 serves to protect against spills of water 18 and overfilling of the water bath 28 and mold 30. The fill lip 56 also serves as a fill indicator. The presence of water 18 in the fill lip 56 informs a user that the mold 30 and water bath 28 are filled with water 18.

From FIGS. 1, 2, 7, 10 and 11, the mold bottoms 34 provide a convenient means to store completed artisan ice portions 38 without allowing the artisan ice portions 38 to touch and without damage to the artisan ice portions 38. When the freezing process is completed, a user removes the artisan ice production unit 16 from the freezer 4, depresses the clip 58 and separates the mold top 32 from the mold bottom 34 and the water bath 28. The artisan ice portions 38 may remain with the mold bottom 34, as shown by FIGS. 10 and 11. The mold bottoms 34, with the artisan ice portions 38, may be stacked as shown by FIGS. 10 and 11 and may be stored in the storage portion 12 of the freezer 4, as shown by FIGS. 1 and 2.

FIG. 11 is a sectional end view of a pair of mold bottoms 34 that are stacked and that contain artisan ice portions 38. FIG. 11 illustrates that each mold bottom 34 defines one or more artisan ice engaging features 68. The artisan ice engaging features 68 of a mold bottom 34 are configured to engage one or more artisan ice portions 38 supported by a lower mold bottom 34. The artisan ice engaging features allow the mold bottoms 34 and artisan ice portions 38 to be stacked without the uppermost mold bottom 34 from sliding from the artisan ice portions 38 supported by the lower mold bottom 34.

The water bath may be insulated against heat loss from its sides to prevent heat loss from the water bath 28 except through the mold bottom 34. Such insulation 64 reduces the energy requirements for the heat source 22. Insulation also may be disposed on the underside of the mold bottom 34, between the mold top 32 and the mold bottom 34 or on top of the mold top 32 to reduce heat loss from the reservoir to the chilled air 14 through the mold bottom 34 and mold top 32 between the shapes 36 defined by the mold 30.

An automated fill system may include a fill pipe 66, shown by FIG. 5.
