Abstract
546,876. Freezing food &c. HIRSCH, M. Oct. 24, 1941, No. 13691. [Class 29] Meat and other solid or liquid food products, with or without previous wrapping, are placed in containers or between smooth surfaces of metal conveyer belts and quickly cooled or frozen by the circulation of cold gas or air outside the containers or belts, the surfaces exposed to the gas having heat transfer ribs or corrugations. A package a, Fig. 1, of the product is placed in a container b having a smooth inside wall and transverse or longitudinal ribs d or corrugations d<2> on the outside. For liquid products several can like containers may be connected together as a single element by the ribs. In the case of irregularly shaped bodies such as meat carcases a ribbed casing in hinged parts may be folded and bent over the product. The casings may be placed on or hung from a conveyer belt ribbed on the inside surface, or may be fed between two such belts f, Fig. 5, from a delivery opening a<1> to a discharge a<3> of a chamber. Baffles m are fitted in the chamber to guide the circulating air or gas. Containers b may be fixed in a chamber q, Fig. 7, provided with an air cooler k and a fan i.
