This disclosure describes systems, methods, and devices for phytochemical extraction. One example extraction system includes two solvent columns, a material column, and a dewaxing column. The solvent columns store and provide solvent for stripping target chemicals from plant material in the material column. The solvent mixed with target chemicals passes into the dewaxing column, where the target chemicals are separated from waxes and lipids. Cooling is applied to elements of the system by way of an open-loop CO2 refrigeration method. Solvent is moved from the solvent columns to the material column by creating a pressure differential between the two solvent columns.

A component extraction apparatus includes a rack placement part, a heater, an extraction medium supply part, a needle assembly, and a temperature sensor. When the container rack is mounted on the rack placement part, a heater is configured to heat the sample containers in direct or indirect contact with sample containers held by the container rack. The needle assembly holds a needle with a tip thereof pointing downward, and the needle being configured to connect a flow channel by inserting the tip thereof into a needle port provided on an upper surface of each of the sample containers. The temperature sensor is included in the needle assembly and is configured to detect a temperature of the upper surface of any one of the sample containers when the tip of the needle is inserted into the needle port of the one of the sample containers.

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.

An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.

A method of producing an extract of an animal-derived or plant-derived biological material includes: extracting a component in the biological material using liquefied dimethyl ether for the biological material to obtain a liquefied dimethyl ether solution including the component; separating the solution from the biological material; and volatilizing or separating the liquefied dimethyl ether from the solution.

The present invention provides for a method for obtaining an oil extract of cannabis. The method includes: (a) contacting cannabis biomass and an edible oil; (b) pressing between a pair of plates to provide spent cannabis and an oil extract of cannabis; and (c) separating the spent cannabis biomass and the oil extract of cannabis.

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.

A process (100) for the recovery of solvent (1) from solvent-containing cellulosic particles (2) is shown, the process comprising the steps: a) extracting the solvent (1) from the cellulosic particles (2) by means of a liquid extraction medium (3), thereby obtaining a solvent-enriched extraction medium (5), and b) obtaining the recovered solvent (6) from the solvent-enriched extraction medium (5). In order to improve the efficiency of the process, it is proposed that in step a) the solvent (1) is extracted from the cellulosic particles (2) in a continuous flow extraction reactor (4), wherein the extraction medium (3) continuously flows through the extraction reactor (4) to extract the solvent (1) from the cellulosic particles (2).

Disclosed are effective methods for activating, washing, specifically extracting and purifying cannabinoids from Cannabis plant tissues using heat activation, washing impurities away with a polar solvent, optionally modified with an organic acid, base, surfactant or inorganic salt, extracting the activated non-polar cannabinoids with a potable selective solvent such as ethanol. The extracted active ingredients may be purified by chromatography and detected and quantified by mass spectrometry with external or isotopic or otherwise labelled standards.
