ABSTRACT:
A controlled atmosphere broiler has a horizontal tunnel mounted on a frame and enclosing one run of a continuous, open-work conveyor traveling from an inlet end toward an outlet end. An air fan near the inlet end supplies air through a supply air duct to nozzles near the outlet end and discharging into the tunnel, both from above and from below, toward the conveyor. The supply air duct air is heated and provided with hot water vapor. The air is further heated by infrared heaters in the tunnel above and below the conveyor. Infrared radiation is reflected toward the conveyor by a reflector, preferably a common wall between the tunnel and the supply air duct. Air from the tunnel is aspirated through a return air duct by the fan. There is a damper control vent from the tunnel to the atmosphere, and air flow in the supply air duct is also controlled by a damper. The conveyor is supported by water-cooled cross tubes, and there is a drain pan below the conveyor.
