ABSTRACT:
A method of cooling coated foods, particularly confectionery and baked goods, wherein the goods are moved by a conveyor belt through a cooling duct, and wherein air is used as the cooling agent. Alternatively, the goods are conveyed by a conveyor belt through a cooling duct above base plates forming heat exchangers, wherein a liquid cooling agent flows through the heat exchangers. The method includes adjusting a delta-T (actual value) between cooling agent exit and cooling agent entry for a certain product to be coated by regulating the cooling agent flow speed, entering this delta-T as nominal value in a computer as the parameter for further cooling of this product, and regulating the cooling agent entry temperature, particularly in the case of production interruption or restart of production, by the difference determined in the computer between the delta-T determined as the nominal value and the actually measured value.
