Abstract:
A system and method of extracting essential oils from plant material through the use of a low pressure alcohol-based closed system that includes a solvent chamber connected to a material column that is, in turn, connected to a kettle. Plant material in the material column and the solvent in the solvent chamber are cooled using a cooling liquid, such as nitrogen. A vacuum pump connected to the kettle creates a vacuum in the kettle to draw the cooled solvent through the cooled plant material and extract essential oils, which are collected in the kettle.

Claim (Index 18):
A non-pressurized, vacuum-only fluid extraction system that extracts plant oil from plant material, the system comprising:\n a solvent container capable of storing a solvent; a material container having an interior capable of retaining the plant material, the interior of the material container in fluid communication with the solvent container; a kettle in fluid communication with the material container to receive plant oil and solvent from the material container, the kettle including a heat jacket capable of heating the kettle; a vacuum pump coupled to the kettle and capable of providing a continuous vacuum to the kettle; wherein the system is capable of performing a process of extracting plant oil from the plant material in the interior of the material container using a continuous vacuum applied by the vacuum pump to the kettle, the process including:\n delivering a cooling liquid into the interior of the material container to mix with the plant material in the interior of the material container and cool the plant material; \n applying a continuous vacuum to the kettle via the vacuum pump without using pressure to thereby apply vacuum in the material container via the kettle; \n forming a mixture of solvent and plant oil from the plant material by pulling the solvent from the solvent container and through the plant material in the material container with the continuous vacuum to extract the plant oil from the plant material; and \n pulling the mixture of solvent and plant oil from the material container and into the kettle with the continuous vacuum.
