US 2014/0193303 A1 · Apparatus for Extracting Oil From Oil-Bearing Plant Material

Abstract

A system for extracting oil from oil-bearing plant parts has an extraction vessel supported by an upright stand and a separator vessel mounted below the extraction vessel. A source of hydrocarbon solvent supplies liquid gas to the top of the extraction vessel, while a recycling pump connected to the separator vessel facilitates transport of the solvent through the plant material in the extraction vessel. The solvent is recovered and re-circulated, while extracted oil is removed from the separator. A thermal jacket is mounted on the separator; the thermal jacket supplies heat and cold to the interior of the separator and helps evaporate and condense the solvent.
