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.
Claims25
An apparatus for extracting essential oils and oleoresins from a plant material, comprising:
- a circulation pump;
- a discharge pump fluidly connected to the circulation pump;
- an extraction module including at least one extraction vessel for receiving the plant material, the at least one extraction vessel having a lower part fluidly connected to the discharge pump and an upper part fluidly connected to the circulation pump, wherein the lower and upper parts are configured with a lower filter and an upper filter, respectively;
- a reservoir fluidly connected to the discharge pump, wherein the reservoir is configured to store a solvent containing a C1 to C4 fluorinated hydrocarbon;
- a first evaporator fluidly connected to the circulation pump;
- and
- a first condenser fluidly connected to the circulation pump, and to the reservoir;
- wherein the apparatus is configured to operate in a short loop circulation mode, and in the short loop circulation mode the discharge pump pumps a solution comprising the solvent and one or more active components of the plant material dissolved in the solution 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.
An apparatus for extracting essential oils and oleoresins from a plant material, comprising:
- a circulation pump;
- a discharge pump fluidly connected to the circulation pump;
- an extraction module including a first extraction vessel and a second extraction vessel, the first extraction vessel having a first lower part fluidly connected to the discharge pump and a first upper part fluidly connected to the circulation pump, and the second extraction vessel having a second lower part fluidly connected to the discharge pump and a second upper part fluidly connected to the circulation pump;
- a reservoir fluidly connected to the discharge pump, wherein the reservoir is configured to store a solvent containing a C1 to C4 fluorinated hydrocarbon;
- a first evaporator fluidly connected to the circulation pump;
- a second evaporator fluidly connected to the first evaporator;
- a first condenser fluidly connected to the circulation pump, and to the reservoir;
- a second condenser fluidly connected to the reservoir;
- and
- a vapor pump for facilitating vaporization of the solvent, the vapor pump being fluidly connected to the first upper part of the first extraction vessel, to the second upper part of the second extraction vessel, to the circulation pump, to the first condenser, and to the second condenser.
