Apparatus (10) for converting liquid (60) in a container (50) to a semi-frozen slurry (61) or frozen ice particles, where a refrigerant (41) is contained within a refrigerant cavity (40) defined by two walls (20, 30), the flexing/deformation of at least one of the walls (20, 30) agitating the liquid
Apparatus (10) for converting liquid (60) in a container (50) to a semi-frozen slurry (61) or frozen ice particles, where a refrigerant (41) is contained within a refrigerant cavity (40) defined by two walls (20, 30), the flexing/deformation of at least one of the walls (20, 30) agitating the liquid (60) to assist the conversion thereof into the semi-frozen slurry (61) or ice particles.

The invention claimed is: 1. A method of converting a liquid into ice particles, using an apparatus including a first wall and a second wall sealably connected together to form a refrigerant cavity; a refrigerant material at least partially filling the refrigerant cavity; when the liquid is brought
The invention claimed is: 1. A method of converting a liquid into ice particles, using an apparatus including a first wall and a second wall sealably connected together to form a refrigerant cavity; a refrigerant material at least partially filling the refrigerant cavity; when the liquid is brought into contact with at least one of the walls, the liquid is at least partially frozen to form a semi-frozen slurry or frozen particles, or a combination thereof, including the steps of: cooling the refrigerant material below a freezing point of the liquid; applying the liquid to the second wall to freeze the liquid into ice particles; and deforming the second wall to release the ice particles from the second wall. 2. The method according to claim 1, wherein the liquid is applied to the second wall in a mist or spray form, such as by one or more spray nozzles; and one or more fans blow air over the second wall, as the second wall is being deformed, to cause the ice particles to fall as ice flakes in a shower-like pattern. 3. The method according to claim 1, wherein the walls include polyurethane, thermoplastic polyurethane, polyvinyl chloride, latex, vinyl, aluminum or foil, or a combination thereof. 4. The method according to claim 1, wherein the liquid includes a carbonated soft drink, a cordial, or a cocktail. 5. The method according to claim 1, wherein the liquid is a non-alcoholic beverage or an alcoholic beverage. 6. The method according to claim 1, wherein the first wall and the second wall each have a respective side wall portion and respective bottom wall portion, where the first wall is enclosed by the second wall and is sealed thereto, either directly or indirectly, to form the refrigerant cavity therebetween. 7. The method according to claim 6, wherein both the first and second wall are flexible; or one of the walls is flexible and the other wall is at least semi-rigid. 8. The method according to claim 7, wherein the walls are formed of polymeric material, rubber, or metal, or a combination thereof. 9. The method according to claim 1, wherein the refrigerant material is a refrigerant fluid or cryogenic material, and the refrigerant fluid includes brine; water/sugar; brine/propylene glycol (food grade); diluted food grade calcium chloride; a refrigerant or other hydrocarbon refrigerant liquid; and the cryogenic material includes dry ice (CO2), nitrogen or other suitable material. 10. The method according to claim 1, wherein the refrigerant material is cooled at least to below −12° C. 11. The method according to claim 1, wherein an agitator or stirrer is operably connected to at least one of the walls to cause agitation of the liquid in contact with one of the walls or to cause release of the ice particles from one of the walls, or a combination thereof. 12. The method according to claim 1, wherein the first wall forms a container to receive the liquid; and the first wall further incorporates an extension portion movable between a first position to enable the liquid to be inserted into the container, or the semi-frozen slurry to be extracted from the container, and a second position sealably closing the container, while the first wall is moved to agitate the liquid within the container. 13. The method according to claim 1, wherein to increase the cooling capacity of the apparatus, at least one cooling coil is provided in the refrigerant cavity, or an adjacent cavity, and is operably connected to a source of refrigerated coolant. 14. The method according to claim 9, wherein the refrigerant is R12, R22 or R134.
