System for providing a single serving of a frozen confection
A system for providing a single serving of a frozen confection, wherein the system comprises a pod comprising at least one ingredient for providing a single serving of a frozen confection; the system cools the pod; the system introduces water into the pod; the system simultaneously stirs the contents of the pod while scraping at least one wall of the pod to prevent a build-up of the frozen confection on the at least one wall of the pod; and the system ejects the frozen confection out of the pod.
1. A method for reducing a temperature of liquid ingredients in an interior of a pod disposed in an evaporator of a machine; the method comprising:
inserting the pod into a receptacle defined by the evaporator, the pod comprising a first end wall, a second end wall, and a sidewall extending from the first end wall to the second end wall;
engaging a mixing paddle with a driveshaft extending through an opening in the first end wall of the pod, the mixing paddle located inside the pod;
rotating the mixing paddle of the pod to force ingredients of the pod downward until contact with the second end wall of the pod churns the ingredients upwards within the pod through openings defined in blades of the mixing paddle by operating a motor mechanically coupled to the driveshaft;
cooling the pod with a refrigeration system of the machine; and
increasing overrun volume of the ingredients in the pod by mixing air flowing through the opening in the first end wall of the pod with the ingredients of the pod.
2. The method of claim 1 , wherein the pod has a wall thickness between 50 and 500 microns.
3. The method of claim 1 , wherein increasing the overrun volume comprises increasing the overrun volume by between 10% to 60%.
4. The method of claim 1 , wherein cooling the pod comprises cooling the pod to a temperature between −40° C. to 0° C.
5. The method of claim 1 , wherein cooling the pod comprises using a two-phase refrigerant.
6. The method of claim 1 , wherein cooling the pod comprises cooling at least a portion of the ingredients to below zero degrees Celsius in less two minutes.
7. The method of claim 1 , wherein rotating the mixing paddle forces the ingredients of the pod radially outward and downward.
8. The method of claim 1 , wherein the refrigeration system comprises a compressor.
9. The method of claim 8 , wherein the compressor is a rotary compressor.
10. The method of claim 8 , wherein the compressor is a reciprocating compressor.
11. The method of claim 1 , wherein the refrigeration system comprises at least one of R290, Freon, R134A, R407C, R404A or R410A.
12. The method of claim 1 , further comprising deforming the pod to provide for close contact with the evaporator.
13. The method of claim 12 , wherein deforming the pod comprises expanding the pod against the evaporator.
14. The method of claim 13 , wherein the pod has a wall thickness between 50 and 500 microns.
15. The method of claim 1 , wherein operating the machine uses a power of less than 1,800 watts.
16. The method of claim 1 , wherein the evaporator comprises aluminum.
17. The method of claim 1 , further comprising dispensing the ingredients from the pod by rotating the mixing paddle.
18. The method of claim 17 , wherein dispensing the ingredients from the pod comprises flowing air through the opening in the first end wall of the pod to the interior of the pod.
19. A method for providing cooled food or drink, the method comprising:
inserting a pod containing one or more ingredients and a paddle into a recess of an evaporator of a machine for providing the cooled food or drink, the pod comprising a floor, a sidewall extending from the floor to define an open end opposite the floor, and a lid attached to the sidewall extending across the open end defined by the sidewall;
connecting a motor of the machine to the paddle by a shaft extending through an opening defined in the lid of the pod;
rotating the paddle inside the pod to mix air flowing into the pod through the opening in the lid with the ingredients to increase a volume of the ingredients of the pod by forcing the ingredients of the pod downward until contact with floor of the pod churns the ingredients upward within the pod through openings defined in the paddle; and
dispensing the ingredients from the pod through an opening in the floor as air flows into the pod though the opening in the lid.
20. The method of claim 19 , wherein rotating the paddle inside the pod to mix air flowing into the pod through the opening in the lid with the ingredients increases the volume by between 10% to 60%.
21. The method of claim 19 , wherein cooling the pod comprises cooling the pod to a temperature between −40° C. to 0° C.
22. The method of claim 19 , wherein cooling the pod comprises using a two-phase refrigerant.
23. The method of claim 19 , wherein cooling the pod comprises cooling at least a portion of the ingredients of the pod to below zero degrees Celsius in less two minutes.
24. The method of claim 19 , wherein rotating the paddle forces the ingredients of the pod radially outward and downward.
25. The method of claim 19 , further comprising deforming the pod to provide for close contact with the evaporator.
26. The method of claim 25 , wherein deforming the pod comprises expanding the pod against the evaporator.
27. The method of claim 26 , wherein the pod has a wall thickness between 50 and 500 microns.
28. The method of claim 19 , wherein operating the machine uses a power of less than 1,800 watts.
29. The method of claim 19 , wherein a refrigeration system comprises a rotary compressor.
30. The method of claim 19 , wherein a refrigeration system comprises at least one of R290, Freon, R134A, R407C, R404A or R410A.
31. A method for providing cooled food or drink, the method comprising:
inserting a pod containing one or more ingredients into a recess of an evaporator of a machine for providing the cooled food or drink, the pod comprising a floor, a sidewall extending from the floor to define an open end opposite the floor, and a cap attached to the sidewall extending across the open end defined by the sidewall;
cooling the pod with a refrigeration system of the machine;
rotating a paddle in the pod using a shaft extending through an opening in the cap; and dispensing the cooled food or drink through an opening in the floor of the pod;
wherein rotating the paddle forces the ingredients of the pod radially outward and downward helping seat the sidewall of the pod against the evaporator; and
wherein rotating the paddle inside the pod mixes air flowing into the pod through the opening of a hole in the cap with the ingredients to increase a volume of the ingredients of the pod.
