A method includes introducing a biomass and a solvent into an extraction vessel to form a mixture, controlling process conditions to increase extraction of target cannabinoids and decrease extraction of impurities, the process conditions including at least one of temperature, solvent composition, and agitation, moving the mixture from the extraction vessel to a separation vessel through a filtration system, balancing a solvent-solute ratio of the mixture as needed, crystallizing the target cannabinoids from the mixture in the separation vessel to produce cannabinoid crystals, separating a mother liquor out of the separation vessel, recovering any residual solvent, and removing the cannabinoid crystals from the vessel.

A method for improving a cell biomass includes de-ashing the cell biomass by applying pulsed electric field (PEF)- or constant electric field (CEF)-treatment to the cell biomass in a solvent, optionally under pressure higher than the ambient pressure, to thereby extract an ash fraction from the cell biomass into the solvent.

A method of extracting at least one cannabinoid from a biomass comprises the following steps (i) contacting the biomass with a solvent formulation which comprises a C.sub.1-4 fluorinated hydrocarbon or a C.sub.1-4 hydrofluorocarbon ether, thereby to charge the solvent formulation with an extract from the biomass; and (ii) separating charged solvent formulation from the biomass.

The present disclosure includes a nozzle and methods for using the nozzle in ways that may increase the efficiency of extraction of essential elements from plant matter. The nozzle may also be used to increase the efficiency of drying solvent saturated plant matter after an extraction has been completed. The nozzle may include an elongated tube with a plurality of holes that allow solvent and/or a gas to be provided or pumped/provided into an apparatus that includes plant matter. Nozzles consistent with the present disclosure may be optimized for extracting cannabis from cannabis plant matter or from other types of plants that include cannabinoids. In certain instances, nozzles may also be used when processing cannabinoid containing concentrates that were extracted from plant matter using any type of extraction technique.

Methods and apparatus for the improved extraction of compounds from a charge material are disclosed. The improved extraction is achieved at least a bypass line that permits the transfer of sCO.sub.2 and/or CO.sub.2 to an extraction vessel and a hopper that achieves greater productivity in loading the extraction vessel.

Controlling the production of an extract using solid-liquid extraction that improves the exchange of material during the extraction process and allows a controlled dehumidification of a raffinate with residual moisture in order to obtain additional valuable extract is described. The steps include providing a first mass in an extraction container, supplying a second mass to the first mass without spatial constraints and distributing and mixing the second mass into and with the first mass, discharging a mixture of the extract and the raffinate from the extraction container, separating the discharged mixture into the raffinate with residual moisture and extracts released from the raffinate with residual moisture, and further treating the raffinate with residual moisture at least such that the residual moisture consisting of the extract is at least partly removed from the raffinate with residual moisture by dehumidification and is supplied to the already separated extract.

A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.

The invention concerns a method and a device for retrieving, from an object A, elements G present in a matrix M, characterized in that it comprises at least the following steps: bringing said abject A into contact with a dense fluid Fd with a molar mass greater than 2 g mol.sup.−1 under temperature T.sub.1 and pressure P.sub.1 conditions suitable for transforming the intergranular phase and for releasing the elements G, (302), modifying the temperature T.sub.2 and/or pressure P.sub.2 values to stop the reaction transforming the intergranular phase, (303), and recovering the elements G separated front the matrix M (304).

The present invention relates to an extraction apparatus for extracting at least one constituent in a substance. The extraction apparatus comprises an extractor, an extraction separator and an extraction condenser. The extractor is used to mix the substance and an extraction fluid, wherein the extraction fluid is a subcritical fluid. The extraction separator is connected to the extractor for receiving and heating the extraction fluid to gasify the extraction fluid and to separate the constituent and the gasified extraction fluid. The extraction condenser is connected to the extraction separator and the extractor for receiving and liquefying the gasified extraction fluid from the extraction separator and sending the liquefied extraction fluid to the extractor.

A system for extracting components from sample material includes a multi-port extraction vessel and an extraction basket that is configured to hold the sample material and to be rotated within the multi-port extraction vessel. The extraction vessel may include multiple ingress ports and multiple egress ports to allow a liquid solvent to flow through the extraction vessel during an extraction process. The extraction basket is permeable to allow liquid solvent to flow through the extraction basket and distribute throughout the sample material held within the extraction basket. A rotation mechanism, such as a motor, may rotate the extraction basket within the extraction vessel during the extraction process. The multi-port extraction vessel, in combination with the rotatable extraction basket, promotes even distribution of the liquid solvent throughout the sample material.
