Abstract
Various aspects of the disclosure relate to methods and systems for extracting plant oil from plant material. A system may comprise a microwave emitter, an extraction chamber, and a cooling chamber. Microwave radiation emitted by the microwave emitter may dielectrically heat a microwave absorbing agent, which may heat the plant oil of the plant material. Plant oil of the plant material may be volatized in the extraction chamber and may be directed into the cooling chamber to be condensed.
Claims22
A method of extracting oil from plant material, comprising:
- providing a system for extracting oil from plant material, wherein the system comprises (a) a microwave emitter, (b) an extraction chamber in communication with the microwave emitter such that microwave radiation emitted by the microwave emitter is directed into the extraction chamber, and (c) a cooling chamber in communication with the extraction chamber such that volatized oil in the extraction chamber is directed into the cooling chamber;
- combining a plant material and a microwave absorbing composition comprising a microwave absorbing agent, the microwave absorbing composition comprising a mixture of solids sized from about 50 μm to about 5 cm, wherein at least some solids of the mixture of solids comprise the microwave absorbing agent, and wherein the microwave absorbing agent is not water;
- inserting the plant material and the microwave absorbing agent into the extraction chamber;
- irradiating the microwave absorbing agent with microwave radiation emitted from the microwave emitter, thereby either dielectrically heating the microwave absorbing agent or heating the microwave absorbing agent by interfacial polarization, heating the plant material, and volatizing a plant oil from the plant material to produce a volatized oil;
- condensing the volatized oil in the cooling chamber, thereby producing a condensed oil;
- and
- collecting a portion of the condensed oil, thereby producing a collected oil that is suitable for human consumption.

A method of extracting tetrahydrocannabinol (“THC”) and/or cannabidiol (“CBD”) from hemp or cannabis, comprising:
- providing a system for extracting oil from plant material, wherein the system comprises (a) a microwave emitter, (b) an extraction chamber in communication with the microwave emitter such that microwave radiation emitted by the microwave emitter is directed into the extraction chamber, and (c) a cooling chamber in communication with the extraction chamber such that volatized oil in the extraction chamber is directed into the cooling chamber;
- combining a plant material and a microwave absorbing composition comprising a microwave absorbing agent, the microwave absorbing composition comprising a mixture of solids sized from about 50 μm to about 5 cm, wherein at least some solids of the mixture of solids comprise the microwave absorbing agent, and wherein the plant material is hemp or cannabis and the microwave absorbing agent is not water;
- inserting the plant material and the microwave absorbing agent into the extraction chamber;
- irradiating the microwave absorbing agent with microwave radiation emitted from the microwave emitter, thereby either dielectrically heating the microwave absorbing agent or heating the microwave absorbing agent by interfacial polarization, heating the plant material to a temperature of about 314° F. to about 450° F., and volatizing THC or CBD from the plant material to produce a volatized oil comprising the THC or CBD;
- condensing the volatized oil to a temperature of about 70° F. to about 365° in the cooling chamber, thereby producing a condensed oil comprising the THC or CBD;
- and
- collecting a portion of the condensed oil, thereby producing a collected oil comprising THC or CBD.

A system for extracting oil from plant material, comprising:
- a microwave emitter;
- an extraction chamber in communication with the microwave emitter such that microwave radiation emitted by the microwave emitter is directed into the extraction chamber;
- a microwave absorbing composition disposed in the extraction chamber, wherein the microwave absorbing composition comprises a microwave absorbing agent, and the microwave absorbing composition is not food, the microwave absorbing composition further comprising a mixture of solids sized from about 0.1 μm to about 5 cm and, wherein at least some solids of the mixture of solids comprise the microwave absorbing agent;
- a plant material disposed in the extraction chamber;
- and
- a cooling chamber in communication with the extraction chamber such that volatized oil in the extraction chamber is directed into the cooling chamber,
- wherein:
- the system is configured to either dielectrically heat the microwave absorbing agent or heat the microwave absorbing agent by interfacial polarization by microwave radiation emitted from the microwave emitter;
- the system is configured to heat the plant material by thermal radiation emitted from the microwave absorbing composition, thereby volatizing oil of the plant material to produce a volatized oil;
- and
- the cooling chamber is operable to condense at least a portion of the volatized oil.
