Abstract

Extrudable food products are deep frozen by applying them on a moving solid steel belt. The surface is frozen by applying a liquid coolant to the products and to the underside of the belt to such a depth that the extruded shape is retained. The products separate readily from the belt when it passes over a return pulley. A second belt conveyor carries the products through the final freezing zone. This is a coat saving process to deep freeze extrudable food products with a minimum of distortion. The strand is easily separated from the conveyor belt.
