  • Patent number: 9687754
    Abstract: A system for extracting oil from oil-bearing plant parts has an extraction vessel supported by an upright stand, a separator vessel mounted below the extraction vessel, and an expansion filter vessel mounted downstream from the separator 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 computer-based temperature control assembly having a cooling device and a jacketed injection coil regulates temperature of the solvent delivered to the extraction assembly. A thermal jacket is mounted on each of the separator vessel and the expansion filter vessel, with the thermal jackets supplying heat and cold to the interior of the separator vessel and the expansion filter vessel and helping evaporate and condense the solvent.
