Animal raw material is comminuted, heated to 40 DEG to 60 DEG C and pressed to form a liquid phase and a solid cake. The fat is separated from the aqueous phase which is concentrated by evaporation, the concentrate optically being added to the press cake. The cake is subjected to drying and sterilization, at least at 110 DEG C (preferably at 120 DEG to 130 DEG C) for at least 10 minutes, before it leaves the dryer and is comminuted to feed meal. |
