A multi-pass thermal treating system for food products which comprises at least first and second zones of thermal treatment; a first zone providing a film contact conveyor comprised of a thermal surface, a traveling thin film, a drive for moving the thin film across the thermal surface, and a control for controlling and monitoring the drive; and a second zone underlaying the first zone providing a second conveyor comprised of a product conveyor, a second drive for the second conveyor and a second control 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. The second and subsequent conveyors may be film contact conveyors, like the first zone film contact conveyor, or they may be open-mesh endless loop conveyors. The first zone film contact conveyor may be maintained at ambient temperature, an elevated temperature, or a lowered temperature. The subsequent thermal treatment zones are refrigeration zones that may be film contact refrigerated conveyors, or updraft, cross-draft or impingement jet refrigerated air open-mesh endless loop conveyors.
