Abstract
An apparatus for extracting an oil from plant material includes an extraction chamber for plant material. The plant material is exposed to a heated gas stream with a temperature sufficient to volatilize on oil from the plant material. The gas stream is rapidly cooled to liquefy the oil into entrained droplets. The oil is collected with a collection solvent.
Claims20
A method to extract an oil from a plant material, comprising:
- providing a system comprising an extraction chamber and a collection chamber;
- providing a plant material comprising an oil;
- inserting the plant material into the extraction chamber;
- producing a heated gas stream in the system;
- directing the heated gas stream through the extraction chamber to convert the oil of the plant material into an extracted oil that is entrained in the heated gas stream;
- directing the extracted oil that is entrained in the heated gas stream from the extraction chamber and into the collection chamber;
- providing a collection solvent, wherein the extracted oil is soluble in the collection solvent;
- contacting the extracted oil that is entrained in the heated gas stream with the collection solvent in the collection chamber to dissolve the extracted oil in the collection solvent;
- and
- collecting the extracted oil.
