  • Cannabis trichome separation using chilled water
    Patent number: 10780442
    Abstract: 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: Grant
    Filed: February 18, 2019
    Date of Patent: September 22, 2020
    Assignee: Nextleaf Solutions Ltd.
    Inventors: Krupal Pal, Thomas Adam Ulanowski, Ivan Casselman, Ryan Delmoral Ko

  • Cannabinoid extraction process using brine
    Patent number: 10406453
    Abstract: 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.
