摘要： A drum contact freezer system which reduces or eliminates a stagnant layer of refrigerant on an interior surface of the drum freezers is provided. A boiling refrigerant is sprayed into the interior of the drum freezers to scrub an interior surface thereof having the stagnant layer. This scrubbing reduces or eliminates the stagnant layer and thus provides an enhanced rate of heat transfer. The boiling refrigerant is preferably in a temperature range of approximately -100.degree. F. to -40.degree. F. at or near atmospheric pressure. Additionally, the boiling refrigerant may be circulated within the drum freezers by providing troughs on the interior surface thereof to help lift the boiling refrigerant and prolong contact between the boiling refrigerant and the interior surface of the drum freezers to provide a further enhanced rate of heat transfer. The material to be frozen may be provided on an outer surface of the drum freezers using a drop nose feed conveyor, soft sponge rollers, or a sprayer assembly depending upon the type of material to be frozen.

摘要： A freezer system which partially freezes food products through conductive heat transfer with rotating contact freezers prior to complete freezing of the food products in an enclosed convection freezer. Food products sequentially contact outer surfaces of two rotating contact freezers, which partially freezes the food products to first and second predetermined depths. The partially frozen food products then enter an enclosed convection freezer for complete freezing. Partial freezing of the food products prior to a complete freeze of the food products provides for a greatly increased rate of production of high quality frozen food products.
