ABSTRACT:
A food refrigerating apparatus comprising a spirally laid endless belt conveyor and an air cooler as the main constituents. The food is refrigerated on its belt-loaded vertically gyrating trip within a channel of cooled air as provided by said air cooler functioning on coolant gas passing therethrough, said coolant gas after attainment of its primary object spraying over said belt to add to the air-caused food refrigerating effect. A casing or casings cover the foregoing constituents for shutting them off from the atmosphere except for openings to place on and take out the food to be frozen from said belt conveyor. Characteristically, in this invention, the spiral and vertical extension of said belt conveyor aims at the elongation of the food conveying distance without a big horizontal space, further said air cooler enables dehumidified refrigeration so as to discard conventional frosting or freezing on the accommodated mechanism.
