Abstract: An improved animal by-products and hides chiller is provided for use in the packing plant for chilling fresh by-products and hides so that spoilage is minimized. The chiller generally includes a rotatable elongated tank having an inlet end for introducing the warm by-products or hides and an outlet end for removing the cooled by-products or hides from the tank. The side wall of the tank is void of apertures such that the need to clean the tank is minimized. As the tank rotates, baffle bars agitate the by-products or hides. The baffle bars are removably secured to the interior of the tank, and can be exchanged with other baffle bars so as to accommodate various types of by-products or hides being chilled. A strainer unit is positioned at the outlet end of the tank and receives the cooled by-products and the liquid coolant. The liquid coolant drains through a plurality of removable straining trays in a strainer unit so as to remove solids from the liquid.
