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 in turn is connected to a recovery chamber. 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 recovery chamber creates a vacuum in the recovery chamber to draw the cooled solvent through the cooled plant material and extract essential oils, which are collected in the recovery chamber.
Claims20
A non-pressurized, vacuum-only method of extracting oil from plant material, comprising:
- cooling plant material in a material container;
- extracting oil from the plant material, the extracting including:
- generating a continuous vacuum in a recovery chamber that is in fluid communication with the material container, the generating the continuous vacuum including using a vacuum pump connected to the recovery chamber only;
- continuously pulling solvent through the plant material in the material container by using only the continuous vacuum in the recovery chamber to extract oil from the plant material and generate a liquid containing extracted oil from the plant material and solvent;
- continuously pulling the liquid containing solvent and extracted oil into the recovery chamber with the continuous vacuum from the recovery chamber and leaving the plant material in the material container;
- and
- purging solvent from the liquid in the recovery chamber.
A non-pressurized vacuum-only method of extracting oil from plant material, comprising:
- introducing plant material into a material container;
- generating a continuous vacuum in a recovery chamber that is in fluid communication with the material container by using a vacuum pump connected to the recovery chamber only;
- continuously pulling solvent through the plant material in the material container by using only the continuous vacuum in the recovery chamber to extract oil from the plant material and generate a liquid containing extracted oil and solvent;
- continuously pulling the liquid containing solvent and extracted oil into the recovery chamber with only the continuous vacuum from the recovery chamber and leaving the plant material in the material container;
- and
- purging solvent from the liquid in the recovery chamber.
A non-pressurized vacuum-only process of extracting oil from plant-based material using an extraction system that includes a solvent chamber in fluid communication with a material column that in turn is in fluid communication with a recovery chamber via a filter, and a vacuum pump that is connected only to the recovery chamber, the process comprising:
- introducing plant-based material into the material column;
- introducing solvent into the material column;
- generating a continuous vacuum in the recovery chamber with the vacuum pump that is connected only to the recovery chamber to continuously pull solvent through the plant-based material and continuously generate liquid containing solvent and extracted oil;
- continuously pulling the liquid containing solvent and extracted oil into the recovery chamber from the material column with only the continuous vacuum from the recovery chamber and leaving plant material in the material column;
- and
- purging solvent from liquid in the recovery chamber.
