An apparatus and a method for plant extraction are disclosed. The apparatus of the present invention comprises an extraction module, a separating module and a reservoir. The method essentially includes plant material preparing, decarboxylating, active components extracting and separating. By using liquid tetrafluoroethane as the solvent in the apparatus of the present invention, the active components of the plant material are efficiently extracted under low pressure extraction and high pressure extraction conditions.

A powdered, water-soluble Full Spectrum Hemp Oil is formed using organic materials and natural products to form a non-GMO, fast acting, whole plant hemp extract without harsh chemicals such as hexane. The Full Spectrum Hemp Oil may be extracted using CO2 concurrent gas extraction to avoid use of chemical additives.

A method and apparatus for extracting active components from a plant material by: introducing the material containing the active components in an extraction chamber: introducing a hydrofluorocarbonated compound in a tank at a pressure between 482.6 kPa and 1,447.9 kPa (70 psi to 210 psi): introducing ethanol in a receptacle; mixing the hydrofluorocarbonated compound with ethanol; allowing the mixture to reach the plant material; allowing the mixture enriched with ethanol and the hydrofluorocarbonated compound to flow out of the extraction chamber and into a tank; allowing the ethanol to evaporate and become separated from the residual mixture slower than the hydrofluorocarbonated compound; optionally, the hydrofluorocarbonated compound is recovered by condensing and returning it to the pressurised tank; optionally, the ethanol is recovered by condensing and returning it to the mixing receptacle.

Systems and methods for extracting solute from a source material in multiple canister systems are shown and described.

Embodiments of the inventive technology may be described as a plant biomass extraction apparatus for production of liquid extract from plant biomass, using carbon dioxide, including one or more of: carbon dioxide chiller, extraction chamber, extract collection chamber, at least one valve, and fluid conveyance componentry, configured to define a closed loop for passive, pump-free extract production. Certain embodiments may avoid saturation of the extractant, and the resultant compromise of process effectiveness that may be seen in those apparatus relying on mechanical pump(s) for flow and/or may present a tabletop, closed loop liquid carbon dioxide extraction apparatus for the production of an extract from plant biomass or other matrix.

A cryogenic solid-liquid extractor comprises a reboiler for evaporating an extraction solvent; a cryogenic heat exchanger for condensing the vaporized extraction solvent to a liquid extraction solvent by passing the vaporized extraction solvent through a container cooled by a cryogenic cooling agent comprising a mixture of a cryogenic solvent and a compressed, liquified or solidified gas to cool the extraction solvent to a temperature below the freezing point of water and above the freezing point of the extraction solvent; a cryogenic extractor for passing the condensed liquid extraction solvent through a solid organic material to extract solvent-soluble material, but not water-soluble material, from the solid organic material, wherein the cryogenic solid-liquid extractor returns the condensed liquid extraction solvent containing extracted material to the reboiler to repeat the vaporization and condensation cycle.

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 column in communication with the tanks.

A system is provided that includes a solvent source; a canister adapted to contain plant material and positioned downstream of the solvent source; an extract container positioned for receiving and collecting at least a portion of an extract solution from at least the canister, the extract container further positioned to separate at least a portion of the solvent from at least the portion of the extract solution, thereby providing a recycled solvent; a solvent collection line for directing the recycled solvent; and a coolant line positioned for directing coolant that is thermally coupled to at least a portion of the solvent collection line for cooling the recycled solvent that is flowing through the solvent collection line.

This disclosure pertains to markers and methods useful in identifying Cannabis plants that have a day length neutral phenotype, and methods of breeding plants having a day length neutral phenotype.

Electric jacket systems and methods for extraction are described. A system may be arranged or arrangeable for electrically controlling a temperature of one or more extraction system components. The system may include a first plurality of thermoelectric devices, the first plurality arranged or arrangeable for coupling with a first extraction system component at multiple locations along the first extraction system component. The system may further include a controller operably coupled to the first plurality of thermoelectric devices, with the controller configured or configurable to establish or maintain at least a first target temperature by selectively applying or causing the selective application of electrical power to the first plurality of thermoelectric devices.
