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.
