Abstract
The disclosed embodiments include systems and methods for the solvent extraction of a substance from a material. The disclosed systems include multiple tanks and an extraction chamber in communication with the tanks. Solvent transport is accomplished by heating and/or cooling selected tanks to cause the solvent to be transported between tanks.
Claims33
An extraction system for extracting compounds from an oil-bearing plant material, the extraction system comprising:
- a first tank adapted to store a solvent and defining a solvent outlet for providing a liquid solvent;
- a second tank defining a solvent-oil mixture inlet that is arranged for receiving a solvent-oil mixture from an extraction column;
- the extraction column defining a hollow expanse that is adapted to hold the oil-bearing plant material, wherein the extraction column further defines a fluid inlet operably coupled with the solvent outlet and a fluid outlet operably coupled with the solvent-oil mixture inlet;
- a first fluid jacket in thermal communication with the first tank;
- a second fluid jacket in thermal communication with the second tank;
- a warm fluid reservoir arranged in selective fluid communication with the first and second fluid jackets for at least one of evaporating the solvent from the solvent oil mixture and transporting the solvent;
- and
- a cool fluid reservoir arranged in selective fluid communication with the first and second fluid jackets for at least one of condensing the solvent and transporting the solvent.
