Abstract: An apparatus for extraction of vegetable oil from vegetable solids, by treatment thereof with solvents, comprises a vessel separated into an upper zone and lower zones by means of a movable perforated plate, upon which the vegetable solids material for extraction can be supported. Suitable solvent is fed into the bed of vegetable material, and percolated therethrough, to extract the oil, the solvent and oil passing downwardly through the perforated plates to collect in a lower zone of the vessel. Another lower zone of the vessel is adapted to receive the treated vegetable solids after the solvent extraction process, this lower zone being provided with movable cover plates, so that solvent and oil does not fall into this vegetable solids receiving zone.
