Title: ESSENTIAL OIL EXTRACTION, RECOVERY, AND PURGE SYSTEM
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 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.
