A METHOD OF CONTINUOUSLY RECOVERING PROTEIN AND FAT BY LOW-TEMPERATURE MELTING OF ANIMAL FAT CONTAINING MATERIAL, COMPRISING THE STEPS OF (1) COMMINUTING SAID MATERIAL TO A PARTICLE SIZE NOT SUBSTANTIALLY EXCEED ING 3MM.; (2) HEATING SAID COMMINUTED MATERIAL TO A TEMPERATURE ABOVE THE MELTING POINT OF THE FAT CONTENTS THEREOF BY DIRECT ADMIXING FAT AT A TEMPERATURE OF ABOUT 70 TO 120* C., AND IN SUCH PROPORTION AND DISTRIBUTION THAT THE AVERAGE TEMPERATURE OF THE MIXTURE DOES NOT EXCEED THE COAGULATION POINT OF THE PROTEIN CONTENTS OF SAID ANIMAL MATERIAL AND IS REACHED BY ALL PARTS OF THE MIXTURE WITHIN A PERIOD OF FEW SECONDS; AND (3) SEPARATNG THE LIQUID FAT FROM THE PROTEIN OF THE MIXTURE.
