ABSTRACT:
A method and apparatus for processing animal byproduct materials is disclosed. In some embodiments, the apparatus includes a grinder for grinding the byproduct materials; a mixer for mixing the ground byproduct materials with an oil absorbing material and a backmix material; and a dryer for drying the mixed materials. In some embodiments, the apparatus also includes a cyclone for separating an air stream from the dried materials. The dried materials are transported to one or more presses for pressing the dried materials, thereby reducing oil content. The one or more presses includes a first opening for delivering pressed oil to a centrifuge and a second opening for sending the pressed materials to a screener. A portion of the screened material is sent back to the mixer (and/or the grinder) and the balance of the screened material are sent to storage as a finished product.
