This invention relates to the extraction of psychoactive compounds from psilocybin fungus for use in medicine. Raw psilocybin fungus is dried and ground. The solvent used for extraction is a lower aliphatic alcohol, water, a hydro-alcohol mixture, an acidic hydro-alcohol mixture, or an alkaline hydro-alcohol mixture. The extraction slurry is filtered and pH-adjusted if necessary. The solvent is then partially evaporated, or completely evaporated with water added back, to form a concentrated slurry. The concentrated slurry is then standardized to provide a known concentration of the psychoactive alkaloids that have been extracted. The standardized slurry may then be dried to result in a powdered psilocybin mushroom extract with a precisely defined purity.

Systems and methods for extracting a compound of interest from plant material, such as a cannabidiol (CBD) from cannabis, are provided. Particularly, the disclosed systems and methods utilize a crude oil to separate water and impurities including fats, sugars, resin glues, chlorophyll, and proteins prior to preparation of a CBD distillate. The systems and methods are operable to remove the impurities from the crude oil with a brine solution and at least one acid prior to distillation. The systems and methods are operable with conventional solvents containing between about 5 wt % and about 8 wt % water.

Devices and methods for the high-pressure treatment of bulk material by extraction and/or impregnation. The bulk material is arranged in the interior volume of a pressure vessel device and is treated at a high pressure while sealed off from the surroundings. The high-pressure treatment is performed batchwise in a closed system in the pressure vessel device in a pressure-tight fashion. The bulk material is fed batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level and, after the high-pressure treatment has occurred, being discharged batchwise from the interior volume with the pressure vessel device closed. The invention furthermore relates to the use of a supporting tray module with at least one treatment level for the high-pressure treatment in a closed system.

Processes for conditioning a dry tailings material from a non-aqueous extraction (NAE) process for extracting bitumen from oil sands ore are described. The process can include contacting a main stream of the dry tailings material with a re-wetted tailings seed stream to produce a combined tailings material, and subjecting the combined tailings material to re-wetting to produce a re-wetted tailings material. The re-wetting can include adding a wetting agent to the combined tailings material, and imparting mixing to the combined tailings material. Contacting the main stream of the dry tailings material with the re-wetted tailings seed stream can include recycling a portion of the re-wetted tailings material to the main stream of the dry tailings material as the re-wetted tailings seed stream to produce the combined tailings material, or subjecting a sub-stream of the dry tailings material to sub-stream re-wetting to produce the re-wetted tailings seed stream.

The present application relates to processing of cannabis material, particularly on a large scale, such as at an industrial level. Cannabis is typically a controlled and regulated substance, and has traditionally been processed in low quantities. A human-based manual and/or labour-intensive processing implementation is not scalable, and is therefore infeasible at an industrial level. Disclosed herein are systems and methods for facilitating industrial-scale processing of cannabis material.

The present disclosure provides an ultrasonic-microwave synergistic extraction method of total saponins in beautiful millettia root, comprising the following steps: S1, material treatment, S2, cold soaking, S3 enzymatic hydrolysis, S4 extract extraction, and S5 ultrasonic-microwave synergistic extraction. The extraction method of the present disclosure extracts relatively high content of total saponins, and has relatively high yield of saponins and low content of impurities, and each step acts synergistically to solve the problems of relatively low total saponin content, more impumayrities and bubbling in the extraction process.

Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.

A method of purifying cannabis derived terpenes includes first providing cannabis material having a detectable amount of tetrahydrocannabinolic acid (THCA), adding a solvent to the cannabis material, spinning the cannabis material in a centrifuge to separate crystallized THCA from a high terpene extract. Decarboxilating the THCA with heat to yield tetrahydrocannabinol. The high terpene extract is deposited into a vacuum oven to reduce pressure and volatilize terpenes from the high terpene extract. Next the terpenes are pumped into a cold trap to condense terpenes from the high terpene extract. Next, the condensed terpenes are cooled at a temperature between −50° C. and 0° C. to remove water from the condensed terpenes and yield purified terpenes. The purified terpenes are applied to an edible food product containing decarboxylated tetrahydrocannabinol. In an alternate embodiment, the tetrahydrocannabinol and the purified terpenes are combined or recombined and mixed directly into a precooked edible food product.

A dry fractionation method and system provides for generating a protein concentrate product therefrom. The method and system includes milling a plant-based flour to generate milled flour and generating a first protein concentrate from the milled flour using an air classifier. The method and system includes processing the first protein concentrate to generate a protein rich curd and generating a neutral hydrolyzed protein slurry by mixing the protein curd with a base, water and enzymatic cocktail. The method and system includes generating a homogenized protein slurry from the protein slurry and generating a cooled protein slurry by pasteurizing the homogenized protein slurry. Therein, the method and system provides for extracting the protein concentrate product from the cooled protein slurry.

A method for producing full spectrum hemp extract comprising extracting substances from cannabis-based green material that are soluble in an extraction solvent and collecting an extract that includes the extraction solvent distilling at least a portion of the extraction solvent which results in a concentrate that is not distilled off, removing at least a portion of water soluble substances from the concentrate by partitioning the at least a portion of water soluble substances into an aqueous phase and a remainder of substances from the concentrate into a partitioned concentrate, heating the partitioned concentrate to evaporate the nonpolar solvent and to yield a crude oil, degassing the crude oil by heating it which results in a degassed crude oil, performing a first pass distillation at about 150° C. and collecting a first residue, performing a second and third pass distillation at about 170° C. and about 185° C., and collecting a distillate from same.
