FREMGANGSMAATE TIL FREMSTILLING AV FORMEL OG FETT FRA ANIMALSKE RAASTOFFER.

摘要

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 DEG to about 135 DEG 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.
