ABSTRACT:
Edible fats and oils are extracted from oil-bearing materials by loading the raw materials onto an inlet end of a flat and fixed conveying surface having elongate slits therein. The materials are conveyed from the inlet end to the outlet end of the conveying surface by scrapers moved by endless chains. Oil extracting solvent is sprayed onto the material on the conveying surface, to produce miscella, which flows through the slits in the surface and into hoppers beneath the surface. The miscella is circulated back to additional sprayers located upstream of the solvent sprayers for spraying the miscella onto the upstream end of the conveying surface. The resulting concentrated miscella is collected in hoppers beneath the surface and delivered to a further use.
