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. Subsequently, all of the output is passed into means for retaining the same, and heating the same, while introducing water or other fluid on which the fat will float in order to separate the fat from the particles. Thereafter, the fat product may be dried in an additional step.
