Within a temperature-controlled process chamber, the RF treatment exposes the Cannabis to an electromagnetic field generated between a set of electrodes inverting its polarity at 27.12 MHz frequency. Pre-programmed process settings designed to kill targeted pathogens regulate the RF voltage between electrodes to achieve a target temperature that kills the pathogens. The efficient process treatment ensures uniform Cannabis treatment at temperatures that will not alter its physical, chemical, functional, or sensorial characteristics.
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.
