Abstract
An apparatus for freezing of food products comprises an insulated housing, an endless, foraminous conveyor belt following a helical path for forming a belt pile having several tiers in the housing, and helical rail means for supporting the conveyor belt at one side thereof along the helical path. Cooled air is circulated through the belt pile. Nozzles for ejecting cooled, pressurized air are positioned between the tiers of the belt pile, such that a plurality of air jets are ejected from the nozzles for impinging upon both a top side and a bottom side of food products carried by the conveyor belt past the nozzles.
