  • Carcass chilling process and apparatus
    Patent number: 6550267
    Abstract: A method for chilling an animal carcass comprises spraying the outer surface of the carcass with a liquid, preferably water, which will freeze on the outer surface of the carcass to form a solid shell to prevent moisture loss from the carcass. Preferably, the liquid is sprayed onto the outer surfaces of the carcass at a critical point in the chilling process at which the outer surface of the carcass reaches a temperature close to the freezing point of the liquid. The liquid is preferably sprayed onto the carcass within a spray cabinet which is preferably positioned along a conveyor line in a refrigeration chamber through which the carcass is conveyed. The spray cabinet comprises heated side walls which maintain a temperature inside the cabinet greater than the freezing point of the liquid, which is sprayed onto the carcass by a plurality of nozzles located within the spray cabinet.
