Green bodies are safely, economically and efficiently debound in a dual quartz reactor by subjecting them to a steady laminar upward flow of freshly distilled solvent so that the concentration difference of soluble binder at the green body/solvent interface is at all times maximized for optimum binder extraction as per Fick's laws of diffusion. Binder extraction rate is monitored by inline spectrophotometry of the reactor overflow. Following solvent extraction, the residual insoluble binder is thermally extracted without the need to transfer the green bodies to a different vessel.

The system can include a shredder, a heating chamber operatively connected to the shredder, a condenser operatively connected to the heating chamber, a solvent tank operatively connected to the condenser, and a circulation unit operatively connected to the solvent tank and the heating chamber.

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.

Provided is an extraction method for extracting an extract from a mixture using liquefied gas that can dissolve the extract, the method facilitating extraction operations and enabling low cost operation. An extraction device that extracts a component dissolved in liquefied gas from material to be treated using continuous phase changes in the liquefied gas is characterized by being provided with: a compressor that feeds gas under pressure; a heat exchanger for generating liquefied gas by the gas flowing in a high temperature side flow path; a treatment tank into which the material to be treated is loaded and the liquefied gas flows; and a retention tank provided in series or in parallel to the flow path downstream of the high temperature side flow path in the heat exchanger.

A plant oil extractor includes a food grade tray with a removable lid that together define an evaporation chamber. A gaseous fluid pump has an inlet fluidly connected to the evaporation chamber and an outlet fluidly connected to an area outside of the evaporation chamber, which may be positioned in a freezer to recover condensed solvent leaving previously dissolved plant essential oil on the food grade tray. A vacuum sublimation freeze drying apparatus includes a container, which defines a drying chamber, is positioned in a freezer. A gaseous fluid pump has an inlet fluidly connected to the drying chamber and an outlet that opens outside the container. Water in fresh herbs positioned in the drying chamber initially freezes and then sublimates leaving behind freeze dried herbs.

Processes and systems for the recovery of solvents from a feedstock are provided, as well as processes and systems for the recovery of target botanical compounds. The processes and systems include a heated mixing device, in which a feedstock can be simultaneously mixed and heated to vaporize and release a solvent or botanical compound from the feedstock. The vaporized solvent or botanical compound can be condensed and collected as recovered solvent or a recovered botanical compound,

A system for processing essential oils includes a mixing tank, three winterization vessels, three respective filtering vessels, a fine filtering vessel, a holding tank, an evaporator, an essential oil reservoir, a solvent reservoir, and a solvent filtering vessel. The evaporator can include a heat exchanger configured to heat a plate down which a mixture including the oils flows, to evaporate other components of the mixture. Fluids can be advanced through the system using a pressurized inert gas.

Purified and modified Cannabis products and methods for producing the same. The purified Cannabis product comprises substantially no volatile organic compounds while retaining Total Potential cannabinoid content. The modified Cannabis product comprises a purified Cannabis product modified by at least one added volatile unsaturated hydrocarbon. The modified Cannabis product is formed by extracting a volatile organic compound from a Cannabis raw material to form a purified Cannabis product, and then adding the at least one volatile unsaturated hydrocarbon to the purified Cannabis product to form the modified Cannabis product and cause an enhanced user experience during combustion and inhalation of the modified Cannabis product.

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.
