Abstract

Cannabinoids can be separated or extracted from plant material. Versions can include a process for separating trichomes from plant material, including mixing plant material with a fluid in a metered feed system and forming a slurry; pumping the slurry into a turbulent processor, agitating the slurry between rotating and static teeth and shearing trichomes from the plant material to form a mixture of fluid, trichomes and plant material; coarse filtering the mixture and removing portions of the plant material to form an interim mixture; and then second filtering the interim mixture and removing other plant material and some trichomes to form a resulting mixture comprising other trichomes and fluid.
