ABSTRACT:
A continuous process for preparing stabilized fat, stabilized protein meal and low fat stabilized bone for producing high quality gelatin and glue from raw organic material containing fat, soft proteinaceous tissue and high density proteinaceous material by crushing the raw material in a rough sizer and continously feeding the crushed raw material to a press to form a soft low density proteinaceous material and a major proportion of the fat. A pressed high density material is discharged from the press separately from the soft wet low density material. The fat is separated from the soft wet low density material, dried and the suspended solids therein removed to provide a stable light colored fat product. The separated pressed high density material and the wet low density material having a low fat content are heated to reduce the moisture content below about 10 wt. percent moisture and effect crisping any fat and tissue adhering to the high density material. The dried low density material and crisped fat and meat tissue are recovered as stable protein meal product. High density proteinaceous material can be separated from the dried material to provide a high quality gelatin bone material.
