Abstract

The present invention relates to a dry process for isolating clean glandular trichomes from a trichome bearing plant material, wherein the trichome bearing plant material is frozen at ?20° C. and subject to shattering and softening sequence.

Claim(s)

1. A dry process for isolating clean glandular trichomes from a trichome bearing plant powder, comprising the steps of: a) freezing a crude trichome powder, comprising said glandular trichomes and contaminants, at a temperature equal to or below ?20° C., b) treating said frozen trichome powder by a mechanical operation to shatter the contaminants into fine dust contaminants, while maintaining said crude trichome powder at a temperature equal to or below ?20° C. and while preserving the glandular trichomes to be purified, c) sifting said crude trichome powder to separate the fine dust contaminants from the glandular trichomes to be purified while maintaining said crude trichome powder at a temperature equal to or below ?20° C., wherein the sifting of the frozen crude trichomes comprises sub-steps, comprising: c1) placing the crude trichome powder into a refrigerated elongated bag having a calibrated pore size, c2) impacting said elongated bag for shattering the contaminants into fine dust, c3) shaking said elongated bag in such a way that the fine dust contaminants are expelled out of the bag through the openings thereof, and c4) repeating steps c1, c2) and c3) until no more fine dust contaminants are expelled from the elongated bag; and d) recovering said purified glandular trichomes while still frozen at a temperature equal to or below ?20° C.
