Abstract:
Provided herein are systems and methods for the facile extraction and purification of oils from plant material, including cannabis and hemp. The systems and methods herein are versatile, and may utilize a wide range of solvents to extract oils from a variety of plant-based material. Further, the provided systems and methods are closed loop, reducing the loss solvent and decreasing the risk of safety concerns such as human exposure to solvent chemicals or explosion of volatiles. In some embodiments, the systems and methods remove impurities from the extracted oils, for example waxes or other precipitates, and provide a higher purity and higher quality extract.

Claim (Index 19):
A closed loop extraction system for extracting oils from plant material; said system comprising:\n a solvent; a solvent vessel; an extraction vessel for housing a plant material, said extraction vessel removably connected to said solvent vessel; a collection vessel positioned vertically below said extraction vessel and removably connected to said extraction vessel and said solvent vessel; wherein said solvent flows from said solvent vessel to said extraction vessel containing said plant material thereby extracting oils from said plant material; wherein said solvent flows from said extraction vessel to said collection vessel and said solvent is converted to a vapor, separating said solvent from said oils, and said solvent flows from said collection vessel to said solvent vessel thereby completing a closed loop; and wherein said solvent flows by a pressure differential generated by temperature difference between two connected vessels, by gravitational force or by a combination thereof.
