Dry (Solventless) extraction

Dry processing involves sifting ground cannabis material through either one screen or a series of metal mesh screens to separate the glandular trichome from the raw plant matter. The screens or meshes are stacked in order of size (for example 140 107 and 70 micrometers) – leaving at least an inch between each screen. The plant material is finely grounded and pushed over the upper screen to begin separating the trichome from the plant material. This process is then further repeated through each screen until finished. It yields a hashish that is typically amber in color containing roughly 90% glandular trichomes. Anything that is not the glandular trichome is considered undesirable and is to be removed if purity is the goal.1 Watch a brief summary video on Cannabis concentrates and extracts made in collaboration with Enlighten on YouTube or on the screens page.
