Abstract: A fat recovery system for hide fleshings and trimmings is disclosed having a grinder for comminuting the fleshings and trimmings, the same being oriented to deliver its parts into a cooker having a steam jacket tube with an interior screw conveyor. After the particulate material has passed through the cooker, a drum type rotary screen is provided from which fat will drop, and the particulate materials pass into a press. Thereafter the solid particulates are removed and the liquid products are delivered into a settling vessel which is heated by steam pipes. Optionally, a drying tank may also be provided. The method of the subject invention essentially includes comminuting the fleshings and trimmings, passing the same through a confined passageway, and agitating the same simultaneously to prevent the particles from coalescing. Thereafter, the particles are screened, and the remaining solids passed into means for pressing the same.
