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 providing cooled food or drink, the method comprising:
inserting a pod into a recess of a machine for providing the cooled food or drink, the pod containing one or more ingredients and a paddle the machine comprising a refrigerant to cool the food or drink;
contacting a sidewall of the pod against a sidewall of the recess;
connecting a motor of the machine to the paddle by a shaft extending through an end wall of the pod;
rotating the mixing paddle inside the pod in a mixing direction to force contents of the pod downward until contact with a floor of the pod which churns the contents upwards within the pod through openings defined in blades of the paddle;
opening a seal closing an opening defined in a floor of the pod; and
rotating the mixing paddle inside the pod in a dispensing direction to force the contents of the pod through the opening in the floor of the pod.
2. The method of claim 1 , wherein the mixing direction and the dispensing direction are the same direction.
3. The method of claim 1 , wherein opening the seal comprises removing the seal from the pod.
4. The method of claim 1 , wherein opening the seal comprises opening a sliding gate of the pod.
5. The method of claim 4 , wherein opening the seal comprises rupturing a portion of the pod.
6. The method of claim 1 , wherein opening the seal comprises rupturing a membrane of the pod.
7. The method of claim 1 , wherein the pod also contains CO 2 or N 2 .
8. The method of claim 7 , further comprising releasing CO 2 or N 2 from the pod.
9. The method of claim 1 , wherein cooling the pod comprises using direct expansion of the refrigerant in the sidewall of the recess.
10. The method of claim 9 , wherein the refrigerant is a two-phase refrigerant and direct expansion of the refrigerant in the sidewall of the recess comprises direct expansion of the two-phase refrigerant.
11. The method of claim 1 , wherein inserting the pod into the machine comprises applying a force to enhance contact between the pod and the machine.
12. The method of claim 11 , wherein applying the force to enhance contact between the pod and the machine comprises closing a lid of the machine.
13. The method of claim 12 , wherein closing the lid of the machine applies force to drive the pod downward in a recess of the machine.
14. The method of claim 12 , wherein the pod expands slightly in application of force on the upper end of the pod.
15. The method of claim 1 , further comprising injecting a pressurized gas into the pod.
16. The method of claim 1 , wherein the cooled food or drink is a frozen confection.
17. The method of claim 1 , wherein the cooled food or drink is produced and dispensed in five minutes or less.
18. The method of claim 1 , wherein the pod contains two to eight ounces of the liquid ingredients.
19. The method of claim 1 , wherein the sidewall of the pod is between 50 and 500 microns thick.
20. The method of claim 1 , further comprising applying a radially-outward force to the wall of the recess by rotating the mixing paddle to force the contents of the pod in a radially outward direction.
