Abstract: Device and method suitable for disinfecting herbs using plasma are disclosed. The device comprises a chamber and two sets of electrodes in an opposed position one relative to the other, inside the chamber. Each electrode in one set has a counterpart electrode in the other set, the two electrodes positioned facing each other and being configured to connect to a RF HV power supply, to produce a plasma-generating EM field in the space between the electrodes. The device further comprises a dielectric carrier positioned inside the chamber in the space between the two sets of electrodes, the carrier being dimensioned and configured to carry herbs in granular form such as powder or particles thereon. A portable sealable container comprising a unidirectional valve is also disclosed, configured to store herbs thereinside during plasma treatment in the device, and to store the disinfected herbs after treatment under vacuum.

Abstract: Device and method suitable for disinfecting herbs in small quantities, e.g. for home use, using plasma, are disclosed. The device comprises a sealable vessel dimensioned and configured to contain herbs in chunks, in granular form such as particles or in powder, in a treatment region of the sealable vessel. The device further comprises a power source configured to generate electromagnetic (EM) power sufficient for plasma generation in a plasma generation region of the sealable vessel. The sealable vessel is optionally detachable from the device. A portable sealable vessel configured to store and transport herbs, the herbs being microbially sealed therein, is also disclosed. The portable sealable vessel may be positioned in a slot of the device so as to generate plasma in the portable sealable vessel and disinfect the herbs. A multi-slot device is also disclosed, enabling plasma disinfection of herbs in a multitude of distinct sealable vessels.
