Abstract

An automated food processing system and method that allows food to be dispensed, fried and packaged in a suitable container, such as an individual portion-sized container. The system includes separate automated modules for dispensing, frying and packaging the food. The food is fried and thereafter it is dispensed from the fry device to an automated packaging device. The automated packaging device dispenses food to a container that may be an individual portion-sized container that is retrieved, erected and filled by an automated container handling and filling system. After a food container is filled, an automated device transports the filled container to a suitable pick-up location.

8. The food packaging device of claim 2 further comprising a movable gate located between the discharge end of the inlet chute and the holding bin and movable between a raised position for retaining French fries on the French fry inlet chute and a lowered position for permitting French fries to travel from the French fry inlet chute to the holding bin.

9. The food packaging device of claim 8 wherein said movable gate comprises a plurality of spaced apart fingers reciprocable in up and down directions to restrain French fries from sliding down the inlet chute when in an up position and for declumping French fries when the fingers are reciprocated up and down when French fries are traveling past the reciprocating fingers.

10. The food packaging device of claim 2 further comprising a sensing device associated with the French fry holding bin for determining whether a desired quantity of French fries are contained in the French fry holding bin.

11. The food packaging device of claim 10 wherein the sensing device is a weighing device.

12. The food packaging device of claim 1 further comprising a French fry carton storage and erection device for open-top individual portion-sized French fry containers.

13. The food packaging device of claim 12 wherein the French fry carton storage and erection device comprises an automated, unerected French fry carton retrieving device for retrieving and grasping an unerected, open-top individual portion-sized French fry container.

14. The food packaging device of claim 13 wherein said automated retrieving device comprises a grasping member for selectively grasping and releasing the French fry container.

15. The food packaging device of claim 14 wherein the automated retrieving device further comprises structure for generally horizontally linearly moving said movable member in two generally horizontal dimensions.

16. The food packaging device of claim 15 wherein said structure for linearly moving comprises a carriage.

17. The food packaging device of claim 15 wherein said structure for linearly moving comprises a carriage for each of said horizontal dimensions.

18. The food packaging device of claim 13 further comprising a magazine for holding a plurality of the individual portion-sized French fry containers in an unerected state.

19. The food packaging device of claim 13 further comprising a magazine for holding a plurality of segregated groups of individual portion-sized unerected French fry containers, each group in the plurality being of a different size container.

20. The food packaging device of claim 19 wherein the magazine holds each group of unerected containers in a horizontal stack.

21. The food packaging device of claim 20 wherein said container retrieving device is positionable to retrieve containers from the front of each stack.

22. The food packaging device of claim 14 wherein said grasping member comprises a suction device for grasping and releasing the French fry container.

23. The food packaging device of claim 22 wherein said suction device comprises a suction cup located on the grasping member that is capable of said grasping and releasing by applying and releasing a vacuum, respectively.

24. The food packaging device of claim 23 wherein said suction device comprises two suction cups that are disposed adjacent each other on the grasping member.

25. The food packaging device of claim 14 wherein said retrieving device is capable of grasping and releasing a French fry container on one side and further comprising means for erecting the unerected French fry container.

26. The food packaging device of claim 25 wherein the container has a bottom and further comprising urging means for urging the container to an erected position and for urging the container bottom upwardly relative to the sides of the container when the retrieving device grasps the container and retrieves the container from the stack.

27. The food packaging device of claim 26 wherein said urging means comprises an inclined ramp.

28. The food packaging device of claim 27 further comprising means for applying a stream of compressed air into the top end of the container and towards the bottom of the container.

29. The food packaging device of claim 26 further comprising an elevator for moving an erected French fry container from a first location proximate said retrieving device to a second location.
