Publication number: 20210379507Abstract: A process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in cannabis oil reacts with acetic anhydride under reflux to produce THC-O-acetate and acetic acid. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.Type: ApplicationFiled: August 21, 2021Publication date: December 9, 2021Inventors: Krupal Devendra Pal, Ryan Delmoral Ko, Brock Aston Hughes, Ivan Jason Casselman

Patent number: 10780442Abstract: Cannabis plant material is gently ground, mixed with chilled water and then agitated. The trichomes, being made brittle by the lowered temperature of the water, fall off the plant material during agitation. The mixture is then filtered in multiple stages to obtain the trichomes in different size fractions, which are collected separately and then dried.Type: GrantFiled: February 18, 2019Date of Patent: September 22, 2020Assignee: Nextleaf Solutions Ltd.Inventors: Krupal Pal, Thomas Adam Ulanowski, Ivan Casselman, Ryan Delmoral Ko

Patent number: 10646793Abstract: Refrigerated solvent is fed through a cooling jacket around an essential element extraction vessel. After circulating through the cooling jacket, the solvent is re-chilled and at least some of the solvent is passed into the extraction vessel, in which essential elements dissolve into the solvent. Downstream of the extraction vessel, after adsorbent media treatment, the extracted oil and solvent mixture is filtered, in a chilled state, through one or more filtration units. A filtration unit may be a system of vertically oriented filters of decreasing pore size sealed and insulated from the atmosphere. Pressurized gas is used to force the oil and solvent through the filters. Each filter stage has a removable lid, which provides convenient access for replacing the filter cartridge without disturbing the thermally insulated sidewalls of the filter stage.Type: GrantFiled: October 22, 2019Date of Patent: May 12, 2020Assignee: Nextleaf Solutions Ltd.Inventor: Ryan Delmoral Ko

Publication number: 20200086229Abstract: Concentrated cannabis extract is obtained from raw cannabis plant material using a mixed solvent extraction process. The cannabis is soaked and agitated in a chilled mixture of butane, propane and isobutane. After removing the solid plant material, the remaining solvent mixture, now with dissolved extracts, is heated to remove the solvents. The remaining, viscous oil is then heated in a vacuum oven to purge the traces of solvent and result in a brittle shatter.Type: ApplicationFiled: September 13, 2018Publication date: March 19, 2020Inventors: Ryan Delmoral Ko, Brock Hughes

Patent number: 10413843Abstract: Raw plant material is mixed with ethanol under pressure to extract essential elements. The resulting crude oil and ethanol with the dissolved essential elements is separated from the raw plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of crude oil and ethanol, and the remaining crude oil then undergoes decarboxylation and distillation to obtain the essential elements. The ethanol may be chilled before adding it to the raw plant material.Type: GrantFiled: May 30, 2018Date of Patent: September 17, 2019Assignee: Nextleaf Solutions Ltd.Inventors: Ryan Delmoral Ko, Brock Hughes

Patent number: 10406453Abstract: Raw cannabis plant material is mixed with ethanol and spun-dry to extract cannabinoids. The ethanol may be chilled before adding it to the raw cannabis plant material, and a non-polar solvent stage may be used to increase the yield of the extraction. The resulting crude oil and ethanol with the dissolved cannabinoids is separated from the raw cannabis plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of oil and ethanol, and the remaining oil then undergoes brine-washing, decarboxylation and distillation to obtain the cannabinoids and other desirable volatile phytochemicals.Type: GrantFiled: August 24, 2018Date of Patent: September 10, 2019Assignee: Nextleaf Solutions Ltd.Inventors: Ryan Delmoral Ko, Brock Hughes, Krupal Pal, Alexzander Samuelsson

Patent number: 10399005Abstract: A series of vertically oriented filters of decreasing pore size is sealed from the atmosphere. Pressurized gas is used to force the liquid to be filtered through the filters. The filter stages are thermally insulated from ambient temperatures in order to maintain the liquid passing through at a reduced temperature. Each filter stage has a removable lid, which provides convenient access for replacing the filter cartridge, allowing it to be changed without disturbing the thermally insulated sidewalls of the filter stage.Type: GrantFiled: March 4, 2019Date of Patent: September 3, 2019Assignee: Nextleaf Solutions Ltd.Inventor: Ryan Delmoral Ko
