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 system for extracting an oil from plant material, the system comprising:
- a gas moving device operable to propel a gas stream through the system, the gas stream being a continuous stream of air or gas with or without entrained vapor, solids or droplets of liquid therein;
- a heater disposed such that the gas stream flows through the heater, the heater operable to heat the gas stream to a temperature sufficient to cause volatilization of an oil to be extracted;
- an extraction chamber having a receiving area for receiving plant material for extraction, the extraction chamber in communication with the heater such that the heated gas stream is directed through the receiving area, the heated gas stream volatizing the oil from the plant material such that the volatilized oil is disposed in the heated gas stream;
- a collection chamber in communication with the extraction chamber such that that the gas stream flows through the collection chamber, the collection chamber having collection solvent operable to collect at least a portion of the extracted oil from the gas stream;
- and
- a liquid collector in fluid communication with the collection chamber for collecting at least a portion of the collection solvent and extracted oil,
- wherein the extracted oil is safe for human consumption;
- and
- the system is configured such that the gas moving device is operable to propel the gas stream through each of the heater, extraction chamber, and collection chamber.
