A quick-freeze thermal treating system for food products which comprises a first zone (10) of thermal treatment. The first zone (10) provides a film contact conveyor (14) comprised of a thermal surface (16), a traveling thin film, a drive (26) for moving the thin film across the thermal surface, and a control (28) for controlling and monitoring the drive. The first zone also provides a convection refrigeration assembly (43) for refrigerating air for distribution onto the traveling thin film, and an air circulating assembly (44) for directing refrigerated air from the refrigeration assembly onto the thin film from above so that food products are crust frozen simultaneously from above and below. A second zone (30) underlaying the first zone (10) may be provided in the form of a second conveyor (34) and a second control (36) for controlling and monitoring the second drive. The second conveyor being located such that food products may be cascaded from the traveling thin film downward onto the product conveyor.
