Abstract
A packing plant by-products chiller includes an elongated tank having an inlet end for introducing fresh animal by-products and an outlet end for removing chilled by-products. The tank is rotatably supported on a set of trunnion wheels and is rotated by a chain and sprocket assembly operatively connected to a motor. A liquid coolant supply line from a coolant source introduces low temperature coolant into the tank. An elongated trough is positioned beneath the tank for receiving warmed coolant which drains from the tank through a plurality of apertures therein. A pump is operatively connected to the trough for recirculating the coolant back to the coolant source. The method of chilling fresh animal by-products comprises introducing the by-products and liquid coolant from the coolant source into the chilling tank located at the slaughter location and rotating the tank such that the by-products therein are tumbled for complete exposure to the coolant. The by-products are pushed through the tank by additional incoming by-products and by the incoming liquid coolant. The coolant drains through the apertures in the tank into the receiving trough and is then recirculated by a pump to the …
