ABSTRACT:
An individual quick freeze apparatus is presented which is designed to allow continuous production of high quality individually quick frozen product, for example food products, using a process which constantly alters the orientation and position of the product which is being frozen. The freezer includes an elongated freezing chamber having a product support extending from a product entrance end to a product exit end. In a preferred embodiment, a plurality of liquid cryogen injectors are provided which spray a cryogenic liquid directly on the product. At least one blower is positioned along at least one the side of the product support to blow cold recirculated gas across the product to cool and agitate the product. The direct liquid/gas contact with the product causes rapid heat removal allowing for more product throughput per length of freezer.
