The seed, having been properly prepared, is separated into a crude oil fraction and a protein meal fraction by solvent extraction. The extractor utilizes a countercurrent, multi-stage washing with commercial hexane solvent to enable a reasonable quantity of solvent to extract a maximum quantity of oil. After washing, the solventladen meal drains by gravity and then discharges to meal desolventising. After washing, the oil/solvent mixture, commonly referred to as “miscella”, discharges to distillation.
