Abstract: Simultaneous slicing and washing of relatively firm raw vegetable or fruit products is accomplished in a vat of water into which a slicer apparatus is positioned such that the slices are formed and discharge directly into the water. An inclined takeout conveyor serves to receive the slices and remove them from the water. A circulating water current and fluid jets urge the slices to disperse onto the conveyor. A spray of water or air blast removes residual vegetable matter from the slice surfaces before leaving the takeout conveyor for further processing. Slicing and washing a vegetable in a flume volute where the slices are dispersed onto a takeout conveyor is disclosed where the water medium is collected in a tub and recycled back to flow in the flume to a level that covers the slicer's operative parts. The apparatus may be used for simultaneous slicing and cooking of raw vegetables where hot cooking oil is maintained in the system and recycled for reheating.

Abstract: An oven for continuous cooking of products carried upon a open mesh wire conveyor provides the impingement of a cooking vapor from air discharge structure having ports arrayed above and below the conveyor. The discharge ports extend laterally of the conveyor and communicate with upper and lower plenums each charged by blower fans which draw cooking vapor from low pressure corridors alongside the product conveyor. Gas, electric or thermo fluid heaters are disposed in the corridors. The discharge ports are in slot form disposed about the apex of a Vee shaped riser spaced from the adjacent riser to provide a low pressure flow channel communicating with the corridors giving a rapid velocity change of the cooking vapor from turbulent to a less turbulent flow. The distance for vapor travel between the upper discharge ports and the product carrying conveyor is variable. Temperature and moisture content of the process vapor can be changed to suit cooking conditions.

Abstract: A fryer for food products such as battered and breaded pieces of meat has a main conveyor with forward and return belt paths inside the fryer pan, the belt return dragging the pan bottom sweeping fines to one end for removal. A submerger conveyor prevents products from floating in the cooking oil which enters the fryer from above through oil inlet weirs. A plurality of weirs supply curtains of hot cooking oil in non-turbulent flow onto the food product covering the product as the product is conveyed on the main conveyor. The cooking oil is returned along defined lanes in the pan for reheating outside of the fryer. The food products are removed from the fryer in a cooked condition with the bread coatings intact.

Abstract: A process and apparatus for preparing a snack food product by baking and without the use of cooking oil, begins with preparation of potatoes, carrots, bananas, etc, into slices, which are surface de-watered before exposure to a high intensity heat source including infra red or open flame at about 1400 F. to blanch the slices and halt enzyme action before exposing the slices to hot, dry air impingement until the slices are reduced in moisture to about 10 to 35%, while the slices are maintained in a mono layer. Then the slices are aggregated into a pack and dried in hot dry air until the moisture content of the slices has been reduced to about 0.5 to 2%.The apparatus includes an insulated housing with a product conveyor belt extending therethrough. A combination of overhead infra-red burners and underneath open flame burners are positioned to create a high energy heat zone along one length of the belt.

Abstract: An oven with a box-like housing for efficient use of plant floor space encases a spiral food product carrying conveyor. A process vapor is circulated within the housing by "plug fans" with the inlet drawing vapor from the central axial zone of the spiral conveyor and exhausting into plenums along the periphery of the conveyor. The plenums have nozzles oriented tangentially to the conveyor for projecting the process vapor in a non-radial path over the food products.

Abstract: Apparatus for continous production of flake ice comprises one or more refrigerated discs mounted on a hollow shaft. Each disc rotates in the vertical plane and includes a plurality of narrow internal channels which extend substantially over all of the operative portion of the disc and are of substantially equal length. The discs form the evaporator of a refrigeration circuit, and an evaporative refrigerant is circulated to the channels in each disc via the hollow shaft. During each cycle, water is applied to both external flat surfaces of each disc at a first angular location and the film of water which adheres thereto freezes as the disc rotates. The ice sheet so formed is removed from both sides of the disc at a second angular location by scraper blades.

Abstract: Weighed, rod-like product is deposited into a receptacle having a bottom wall formed by an iris plate assembly, which may be vibrated and which opens on command to drop the product into one of two cylindrical holding canisters with clamshell doors on their sides. The canisters are mounted in an "L" configuration which toggles back and forth through a 90 degree rotation presenting each canister first in a vertical position to receive product from the receptacle and then in a horizontal position to release product via the clamshell doors into a pocket such as a timing hopper, or a paperboard tray carried by a conveyor to a packaging machine. Interlocks are provided to preclude release of the product or movement of the conveyor when synchronization is lost with respect to either the weighing or packaging machine.
