Abstract
Raw cannabis plant material is dried, coarsely ground, agitated while chilled, sifted and collected to result in cannabis plant material rich in trichomes. Dried cannabis plant material is coarsely ground using a grinder. The coarsely ground cannabis plant matter is agitated in a tumbler in a cooled environment to separate the trichomes from the remainder of the plant matter. The trichomes are then sieved using a sieve shaker with sieves of different mesh sizes mounted in a tower. Chilling the plant material embrittles the trichomes so that they can be removed more easily from the remainder of the plant material.
