Animal raw material is boiled at least mainly by indirect heating and then divided into stick water and solids, the solids being separately dried to form a first meat meal fraction. The stick water, preferably after separating a sludge component and a fat component therefrom, is concentrated by evaporation and then divided into a sludge phase and a fat phase, the sludge phase being dried to form a second meat meal fraction. |
