ABSTRACT:
To separate animal raw material into fat and protein fractions, the material in finely divided form is circulated through a circuit which includes a heating zone where the material is continuously heated to a relatively low temperature of about 45.degree.-70.degree. C., and a stream of warm material from this circuit is then quickly heated to a higher temperature of about 85.degree.-100.degree. C. This quickly heated material is immediately subjected to centrifugal separation in one or more stages to provide the two fractions of fat and protein, respectively.
