Abstract

A machine prepares semi frozen food products and/or beverages from pre-prepared (e.g. frozen) cups. A user chooses the desired frozen cup, inserts it into the machine, chooses how they would like it prepared from a range of thickness options, and the machine then opens a sealed chamber door and inserts the product upward into the chamber and prepares the product by blending it in the cup. Upon removal of the product and resealing of the chamber door, the cleaning mechanisms provide thorough cleaning of all food contact surfaces and the chamber interior. Automatic high temperature steam sanitation takes place in the chamber if the machine is not used for an extended period of time, thus greatly reducing or eliminating the need for manual cleansing and sanitation by an attendant and ensuring healthy food preparation at all times.

Claims

1. A food preparation apparatus comprising;

a chamber comprising a door which seals, the chamber when the door is in a closed position;

a carriage comprising a cup holder;

a motor that transports the carriage with the cup holder into the chamber from a starting position and returns the carriage to the starting position wherein said chamber door is opened when said carriage enters said chamber and closed after said carriage leaves said chamber; and

a cleaning system comprising a plurality of nozzles, a fluid reservoir and a fluid pump wherein, after said carriage leaves said chamber, pump pressurized fluid from said reservoir is sprayed into said chamber from said nozzles to clean said chamber.

2. The food preparation apparatus of claim 1, further comprising a flow meter to measure and dispense precise amounts of fluid.

3. The food preparation apparatus of claim 2, further comprising at least one fluid heater.

4. The food preparation apparatus of claim 3, wherein a fluid heater heats fluid to become steam.

5. The food preparation apparatus of claim 1, wherein said nozzles include both rotary nozzles and fixed nozzles.

6. The food preparation apparatus of claim 5, wherein fluid supplied to at least one of said fixed nozzles is heated.

7. The food preparation apparatus of claim 5, further comprising a manifold to distribute fluid to said rotary nozzles and said fixed nozzles.

8. The food preparation apparatus of claim 1, wherein said cupholder is capable of holding a cup with frozen food.

9. The food preparation apparatus of claim 8, further comprising a mixing blade.

10. The food preparation apparatus of claim 9, further comprising a lid that is placed over said cup during mixing.

11. The food preparation apparatus of claim 10, wherein said lid is connected to a rotary shaft which turns said mixing blade.

12. The food preparation apparatus of claim 11, wherein said lid tilts to allow it to be more easily cleaned when it is not in contact with said cup.

13. The food preparation apparatus of claim 8, wherein fluid from said reservoir is added to said frozen food as it is being mixed.

14. A food preparation apparatus comprising:

a chamber comprising a door at an underside of the chamber that seals the chamber when the door is in a closed position;

a carriage comprising a cup holder;

a motor that elevates the carriage and the cup holder into the sealed chamber from a starting position and returns the carriage to the starting position wherein said chamber door is opened when said carriage enters said chamber and closed after said carriage leaves said chamber; and

a cleaning system comprising a plurality of nozzles, a fluid reservoir, a fluid pump, a flow meter and at least one heater wherein, after said carriage leaves said chamber, a measured amount of heated and pump pressurized fluid from said reservoir is sprayed into said chamber from one or more of said nozzles to clean said chamber.

15. A food preparation apparatus comprising:

a chamber comprising a door at a lower portion of the chamber sealing to the chamber when the door is in a closed position;

a carriage comprising a cup holder;

a motor that elevates the carriage and a cup within the cup holder into the sealed chamber from a starting position and returns the carriage and cup to the starting position; and

a water delivery system that dispenses water into the cup as a blade mixes a product within the cup during a food preparation cycle,

the water delivery system further comprising one or more fixed scouring nozzles to automatically deliver water to an underside of a weighted cup lid following each preparation cycle when the door of the chamber is in a closed, sealed position and one or more rotary nozzles configured to spray water on walls of the chamber.

16. The food preparation apparatus of claim 15, wherein the water delivery system is further configured to activate and dispense water from a first rotary nozzle after a threshold period of time since a previous cleansing of the chamber has been met or exceeded.

17. The food preparation apparatus of claim 16, wherein the water delivery system is further configured to refill a water reservoir coupled to the first rotary nozzle after said rotary nozzle has dispensed the water.

18. The food preparation apparatus of claim 17, wherein the water delivery system is further configured to activate and dispense water from a second rotary nozzle after the reservoir has been refilled.

19. The food preparation apparatus of claim 15, wherein the water delivery system further comprises a reservoir and a pump located upstream of the one or more rotary nozzles, the reservoir sized to provide a water supply sufficient to allow the nozzles to dispense water at a rate of 3-5 gallons per minute for 1-3 seconds.

20. The food preparation apparatus of claim 19, wherein the pump is located between the reservoir and the one or more nozzles.

21. The food preparation apparatus of claim 15, further comprising a heater for heating the water that is dispensed into the cup.

22. The food preparation apparatus of claim 21, wherein the apparatus is configured to utilize the heater to generate steam for sanitizing the apparatus.

23. The food preparation apparatus of claim 22, wherein the heater is controlled to heat water up to 235 degrees Fahrenheit.

24. The food preparation apparatus of claim 23 wherein the apparatus comprises

a water line to deliver both the water dispensed into the cup and the steam used to sanitize the chamber.

25. A food preparation apparatus comprising:

a chamber comprising a door at a lower portion of the chamber that seals the chamber when the door is in a closed position

a carriage comprising a cup holder;

a motor that elevates the carriage and a cup within the cup holder into the sealed chamber from a starting position and returns the carriage and cup to the starting position;

a first set of nozzles within the chamber configured to spray water in a fixed position onto the inside of said chamber; and

a second set of nozzles within the chamber comprising at least one rotary nozzle to spray water in a rotating pattern,

wherein the apparatus is configured to activate the first and second set of nozzles when the chamber door is in a closed, sealed position.

26. A food preparation apparatus comprising:

a food preparation chamber which can be sealed for cleaning after food is prepared in the chamber and removed; and

,

a cleaning system to clean the interior of the food preparation chamber after sealing comprising a fluid reservoir, a fluid pump, a flow meter and a plurality of nozzles such that a measured amount of pump pressurized fluid from said reservoir can be sprayed by said nozzles to clean the interior of said food preparation chamber.

27. The food preparation apparatus of claim 26 further comprising a heater to allow one or more of said nozzles to spray heated cleaning fluid.

28. The food preparation apparatus of claim 27 wherein said fluid is water and said heater is capable of heating said water until it becomes steam.

29. The food preparation apparatus of claim 28 further including a steam port.

30. The food preparation apparatus of claim 26 wherein said nozzles include both fixed nozzles and rotary nozzles.

31. The food preparation apparatus of claim 26 further including a manifold to distribute fluid to said nozzles.
