Abstract
For extracting undesirable components from vegetable tissues, more particularly from oil-bearing seeds having been stripped of the predominant fraction of their fatty components, a method is disclosed in which a number of serially arranged vessels equipped with stirring means is used in such a way that the materials to be treated are initially contacted by partially exhausted solvent and progressively with cleaner and cleaner solvent so that, when the solid materials are almost completely exhausted, they are washed with fresh solvent. The vessels are changed in rotational sequence, so that the system is continuous as regards the solvent and is discontinuous with respect to the solids.
