The invention relates to a method and a device for deep-frying products to be deep-fried with hot fat. Fat that is conveyed in a circuit by a pump is heated, brought into contact with the product to be deep-fried and filtered. The quantity of fat circulating in the circuit is kept to a minimum by us
The invention relates to a method and a device for deep-frying products to be deep-fried with hot fat. Fat that is conveyed in a circuit by a pump is heated, brought into contact with the product to be deep-fried and filtered. The quantity of fat circulating in the circuit is kept to a minimum by using a heating device in which a minimal volume of fat reaches the required temperature as quickly as possible for heating the fat and by using lines with as small cross-section as possible and which are as short as possible for transporting the fat.

A method according to claim 1, wherein at least one tier comprises a conveyor which is configured to define a first and at least a portion of a second travel track thereon, the second travel track being laterally spaced apart from the first, and wherein the at least one food item travels over the first and at least a portion of the second travel track to travel greater than one revolution in the tier before moving to the next selected tier. 13. A method according to claim 12, wherein the first and second travel tracks are configured from a looped conveyor. 14. A method according to claim 12, wherein the conveyor defines a spiral travel surface pattern thereon. 15. A method according to claim 1, wherein the at least one food item travels greater than one revolution in a plurality of the tiers. 16. A method according to claim 1, wherein the at least one food item travels at least about 1.5 revolutions in a first tier before moving to a second tier where the at least one food item travels at least about 1.5 revolutions before moving to a third tier where the at least one food item travels at least about 1.5 revolutions before moving to a fourth tier. 17. A method according to claim 9, wherein one of the conveyors runs at a first speed and another of the conveyors runs at a second speed different from the first speed on at least one of the tiers. 18. A method according to claim 2, further comprising alternating the lateral travel pattern of the at least one food item as it moves between adjacent tiers such that the food item travels from an inside to an outside perimeter on a first tier and then an outside to an inside perimeter on an adjacent tier. 19. A method according to claim 1, wherein each tier has a desired temperature associated therewith and the at least one food item is exposed to the tier temperature for a time corresponding to the conveyor speed as it travels through that tier. 20. A method according to claim 1, wherein the at least one food item is an elongated food item. 21. A method according to claim 1, wherein the at least one food item is a substantially continuous length elongated meat product. 22. A method according to claim 1, wherein the food processor comprises an inner column of tiers and an outer column of tiers, each column defining a separate travel path for a desired at least one food item, and wherein the outer tier is configured to encase the inner tier. 23. A method according to claim 22, wherein different food items are concurrently directed to travel through the inner and outer column of tiers. 24. A method according to claim 22, wherein the inner column of tiers correspond to an inner oven and the outer column of tiers correspond to an outer oven, and wherein each of the inner and outer column of tiers at each tier level are separately regulated for desired operating environments. 25. A method according to claim 1, wherein the at least one food item is an elongated meat product having a length which extends over a major portion of the predetermined travel path. 26. A method according to claim 1, wherein the at least one food item is an elongated meat product with a length which is sufficient to extend over a predetermined portion of the travel path corresponding to at least a plurality of tiers. 27. A method according to claim 26, wherein the at least one food item is an elongated meat product which has a length which extends over substantially the entire predetermined travel path in the food processor. 28. A food processing apparatus comprising: a housing defining an enclosure and having a food inlet and a food outlet; and a plurality of stacked tiers residing in said housing, each of said tiers including at least one conveyor configured to move a food product in a predetermined travel path over a primary surface of a respective tier such that the food product moves in a first path having a first perimeter and then to a second path having a second perimeter different from the first perimeter so as to travel greater than one revolution in each tier. 29. An apparatus according to claim 28, wherein said at least one conveyor for each tier comprises a conveyor which is configured to define greater than one revolution and to define a serial portion of the travel path for a respective tier thereby directing the food product to travel greater than one revolution on the same conveyor. 30. An apparatus according to claim 28, wherein said at least one conveyor comprises a conveyor which is configured to move the food product more than one revolution on the same conveyor. 31. An apparatus according to claim 28, wherein the first and second paths are substantially circular, and wherein the first path has a first radius and the second path has a second radius different from the first radius. 32. An apparatus according to claim 31, wherein at least one tier is disk shaped, and wherein the conveyor comprises two separate food exchange ports, one located outside the outer perimeter of the disk and the other located inside the inner perimeter of the disk, and wherein the first and second paths are arranged to define a spiral travel path. 33. An apparatus according to claim 28, wherein the at least one conveyor comprises a plurality of side-by-side cooperating conveyors. 34. An apparatus according to claim 28, further comprising a heating chamber disposed in said housing so as to direct heat to at least one of the tiers, said heating chamber configured to heat the food product as it moves through said heating chamber on the at least one conveyor. 35. An apparatus according to claim 33, wherein said plurality of side-by-side cooperating conveyors are first and second conveyors configured to define a cooperating pair of conveyors, and wherein each tier further comprises a transfer junction operably associated with each pair of conveyors which directs the food product from the first conveyor to the second conveyor. 36. An apparatus according to claim 28, wherein each tier is configured with a food transfer region to move the food from one tier to the next selected tier. 37. An apparatus according to claim 35, further comprising a food transfer region which includes a drop zone extending about a portion of the second conveyor, wherein, in operation, the food product moves about a first revolution on the first conveyor and is diverted to move about a second revolution on the second conveyor in the tier and then approaches the transfer region to travel therethrough to the next underlying tier for further processing. 38. An apparatus according to claim 35, further comprising a food transfer region, wherein, in operation, the food product moves about a first revolution on the first conveyor and is diverted to move about a second revolution on the second conveyor in the tier and then approaches the transfer region to travel therethrough to the next overlying tier for further processing. 39. An apparatus according to claim 28, further comprising a food transfer region operably associated with each tier, said food transfer region configured to direct food to travel from one tier to another tier, and at least one food diversion means which helps direct the food to change travel paths on each tier. 40. An apparatus according to claim 28, further comprising a cooling chamber operably associated with at least one of said tiers. 41. An apparatus according to claim 28, wherein said inlet is configured to direct a continuous length of an elongated food product therein. 42. An apparatus according to claim 39, further comprising at least one intermediate conveyor positioned in communication with a selected portion of said at least one conveyor so as to define a minor portion of at least one of the first or second paths in said tiers. 43. An apparatus according to claim 28,
