  • Patent number: 11766629
    Abstract: An apparatus for extracting essential oils and oleoresins from a plant material is disclosed. The apparatus comprises a circulation pump, a discharging pump, an extraction module, a reservoir, a first evaporator, and a first condenser. The discharge pump is fluidly connected to the circulation pump. The extraction module includes at least one extraction vessel. The reservoir is configured to store a solvent containing a C1 to C4 fluorinated hydrocarbon. In a short loop circulation mode the discharge pump pumps a solution comprising the solvent and one or more active components of the plant material dissolved therein from the bottom of the at least one extraction vessel, passing through the circulation pump, and then back to the top of the at least one extraction vessel.

  • Patent number: 10870069
    Abstract: This invention discloses an apparatus for extraction of constituents with extraction fluid present in a substance by means of an extraction fluid constituted by a water heated to high temperature known as super-heated water (SHW). According to this invention, in the heater the water is heated to a subcritical point and introduced to the extractor contacting takes place between the substance and the extraction fluid to dissolve the constituents in the fluid. The fluid leaving the extractor is then cooled in a cooler. The process is performed under constant counter pressure given by a Nitrogen tank. Separation of the volatile components is done in one or multistage countercurrent liquid-liquid system with any volatile solvent with proper solubility of the constituents or in a distillation column. distillation column.
