ABSTRACT:
Apparatus for gas stunning of poultry in open top drawers (22) comprises a tank (10) holding a heavier than air stunning gas such as a mixture argon and carbon dioxide. A lowering conveyor (24) receives the poultry-containing drawers (22), lowers them into the tank and delivers them to the infeed end of a series of conveyors (28) which transport the drawers (22) through the tank to the base of a lifting conveyor (32) which lifts the drawers and delivers them to the infeed end of a conveyor (34) which transports the dead poultry away for slaughtering. The conveyors (24, 28) are provided with covers (26, 30) to prevent the poultry escaping from the drawers. The drawers (22) are moulded with apertured sides and bases to allow penetration of the gas into the drawers so that the poultry is exposed to the gas for a time sufficient to kill the poultry, or at least render the poultry anoxic.
