How to remove moulds and yeast from Cannabis

How to meet regulatory standards required for Cannabis cultivation.

Moulds and yeasts are a serious and common problem that many Cannabis growers face every day, in both indoor and outdoor cultivation. Stalam has developed a solution to this problem: the post-harvest Radio Frequency sanitisation of Cannabis and other medicinal or aromatic herbs. The “RF” series equipment for the batch sanitisation of Cannabis is based on the use of Radio Frequency energy at 27.12 MHz (ie. a nonionizing electromagnetic field), which represents today a much better alternative to conventional thermal processing methods for the disinfestation, disinfection and pasteurisation of a wide range of temperature-sensitive substrates. In the Stalam “RF” sanitisation system the inactivation of the required species (pests, moulds, yeasts, bacteria, etc.) is achieved by means of a gentle and rapid dielectric heating treatment, at temperatures that may range from 60-70°C to 100-110°C according to the target species, which combines synergetically thermal and cell membrane electroporation effects.

This dual action of the RF field is lethal for the biological entities contaminating the substrate, thus providing an effective sanitisation and shelf-life extension technique. Significant reduction of the contaminating species can be achieved without using chemicals or applying drastic thermal treatments which would have detrimental effects on the physical, chemical, functional and sensorial characteristics of the product, such as causing terpenes and THC loss in the specific case of Cannabis.
