<p>Process for preparing low fat stabilized bone which can be used for producing high quality gelatin. Trimmed raw bone is fed continuously to a screw type press, mounted within a cage having a choke and perforations in the wall of the cage through which soft non-bone material is extruded. The pressed bone is heated in an oven to crisp the fat and meat tissue adhering to the pieces of bone such that the crisp fat and meat tissue is readily separated from the bone during the heating, tumbling and screening thereof. The baked crushed bone is subjected to dry separation by first passing it over a sizing screen and then passing the exiting material having a selected particle size range to a gravity separator. The above enables production, in an economical manner, of a clean low-fat bone in which the bone protein is not degraded. </p> |
