All oleaginous materials have a somewhat different cell structure and, therefore, a different time required for the miscella in the cells of the oleaginous material to come into equilibrium with the miscella outside of the oleaginous material. Soybean flakes have a cellular structure (16) that will allow equilibrium to occur within approximately 5 minutes at each extractor wash, whereas sunflower cake requires approximately 9 minutes and rapeseed cake requires approximately 12 minutes.
