Abstract

A process for trichome separation from plant matter deploys water slurry agitation and/or dry sieving to produce a mixture of solid trichomes and similar sized plant debris. The plant debris in each separate fraction is then removed by gravity filtration in a dense inert liquid, which is preferably a salt or brine solution. The desirable trichomes or trichome glands float on the dense liquid, while the undesirable vegetative matter sinks to the bottom of the brine containing vessel. The trichomes are readily removed and washed before further processing.

Claim(s)

1. A method of trichome separation from plants, the method comprising the steps of: a) obtaining a trichome bearing plant material, b) agitating the plant material, d) introducing the plant material in fluid having a density of at least about 1.01 gm per cc to float the trichomes on the fluid, e) removing the floating trichomes, f) rinsing the removed trichomes to remove a residue of the fluid, and g) drying the rinsed trichomes.;
10. A method of trichome separation from plants, the method comprising the steps of: a) obtaining a trichome bearing plant material, b) agitating the plant material, d) introducing the plant material in fluid having a density of at least about 1.01 gm per cc to float the trichomes on the fluid, e) separating the floating trichomes from the fluid, f) removing any residue of the fluid from the separated trichomes.;
20. A method of trichome separation from plants, the method comprising the steps of: a) obtaining a trichome bearing plant material, b) agitating the plant material to release trichome from the plant material, d) introducing the plant material in fluid having a density of at least about 1.01 gm per cc the plant matter from which trichomes were released sinks in the fluid, e) separating the trichomes from the fluid, f) removing any residue of the fluid from the separated trichomes.
