ABSTRACT:
A cryogenic freezer is disclosed for embrittling scrap material, such as random size pieces of automobile tires, prior to fragmentation of the embrittled scrap material in an impact mill. The freezer includes a product discharge gas lock which is designed to minimize the loss of cryogenic refrigerant while, at the same time, accomodating unusually large pieces of scrap material.
