An apparatus for gas treatment of products, especially food products, comprises a housing (12) having an inlet opening (18) and an outlet opening (19). A conveyor belt (8) transports the products through the housing along a path from the inlet opening to the outlet opening. A tunnel (13) encloses the conveyor belt at least along a part of the path from the inlet opening to the outlet opening, and has a perforated top wall (15). Gas suction means (14) communicates with the tunnel for creating a vacuum in the interior of the tunnel. Gas conditioning means (31) conditions the gas circulated by the gas suction means from the interior of the tunnel to the exterior thereof and back to the interior of the tunnel through the perforated top wall thereof. In this manner, gas sucked through the perforated top wall of the tunnel from the exterior thereof forms gas jets impinging upon the conveyor belt.
