procedure and installation for improving the quality of fat or oil plant or animal raw materials for the manufacture of naerings and feed materials

摘要

Process and device for improving the quality of Fat- or oil-Containing plant raw Materials (FCM), or their residues, intended as foods or feeds. By thermal treatment in the presence of water or steam in a continuous process the material is introduced in a first step with a temperature of approximately 100 DEG C into a pressure treatment chamber (4) and remains there for approximately 3.5 to 10 minutes at max. temperatures of 135 DEG C and a max. pressure of 5 bar. In a second treatment chamber (8) the material is reduced in pressure to 0.1 to 1.0 bar and is removed from there after a residence time of approximately 30 seconds at a temperature of less than 100 DEG C.
