Abstract: The apparatus for the production of fodder and fat from animal raw materials such as slaughter house waste includes a heating apparatus for heating the raw material, a pressing apparatus for separating the heated material into a solid material phase and a fluid phase, a drier for drying the solid material phase to remove water and an evaporator for evaporating the fluid phase. The evaporator receives waste heat from the drier to carry out the evaporation of the fluid phase.

Abstract: Process for the production of fodder and fat from animal raw materials, such as slaughterhouse waste. The raw material is subjected to heating to a temperature of from about 60.degree. to about 135.degree. and is separated thereafter into a solid material phase and a fluid phase. The solid material phase is subjected to a separate drying step and thereafter steps for the separation of fat and solid material individually. The fluid phase is subjected to separate evaporation the evaporation product being wholly or partially supplied to the solid material phase for separation of fat and solid material individually. Heat energy in the gases emitted from the drying step of the solid material phase is used in an evaporation step for the fluid phase.
