Sift

Sifting consists of passing material through a screen or grid in order to separate particles according to their size. This technique is used in many fields, including agriculture, food, industry and hemp processing.

Why sift?

Sifting makes it possible to sort, filter or select certain particles present in a mixture. Depending on the mesh size used, finer elements can be collected while larger particles are retained.

This method produces material that is more homogeneous and better suited to the intended use.

Sifting hemp and cannabis

In the world of hemp, sifting is mainly used to separate trichomes from the rest of the plant material. Since trichomes are more fragile than other parts of the plant, they can be detached and collected using suitable screens.

This technique is used in particular in the production of kief, pollen or certain resins obtained through mechanical separation.

Influence of mesh size

The result depends heavily on the diameter of the screen mesh. A larger mesh allows more plant material to pass through, while a finer mesh generally enables more precise selection of particles.

Manual or mechanical sifting

Sifting can be carried out manually or using specialised equipment. Some processes also use cold temperatures to facilitate the separation of trichomes and improve the efficiency of the operation.

Key points

Sifting consists of sorting material according to the size of its particles using a screen. In the hemp sector, this operation is often used to separate trichomes from plant material and obtain different fractions intended for specific uses.
