Cannabis Trichome Separation Using Chilled Water
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.

- 1. A process for separating trichomes from raw cannabis plant material comprising:
grinding the raw cannabis plant material using a mesh size between 1 cm and 2.5 cm to result in ground raw cannabis plant material; adding water at a temperature below 10° C. to the ground raw cannabis plant material to form a mixture; agitating the mixture to separate trichomes from the ground raw cannabis plant material; straining the mixture using a coarse mesh with a pore size of 200-1000 μm to separate the mixture into a trichome filtrate and unwanted cannabis plant matter; filtering the trichome filtrate to retain a residue of trichome-rich cannabis plant matter; and drying the trichome-rich cannabis plant matter to form a powder.
