Plasma treatment device

A plasma treatment device, comprising:

• a first electrode;
• a second electrode having an opposite polarity as the first electrode;
• a non-conductive mesh with a seating portion;
• and
• at least one dielectric body supportive of the first electrode or interposed between the second electrode and the non-conductive mesh, wherein:
• the seating portion of the non-conductive mesh is configured to collect particles, the first and second electrodes are arranged such that, with the second electrode activated, a plasma field is generated to treat the particles in the seating portion and the seating portion being configured to retain the particles during treatment in opposition to ionic winds resulting from the plasma field.

A method of operating a plasma treatment device, the method comprising:

• supporting a first electrode on a dielectric body;
• disposing a second mesh electrode having an opposite polarity from the first electrode and comprising a seating portion proximate to the dielectric body to define a gap receptive of particles for collection in the seating portion;
• dispensing the particles into the gap such that the particles collect in the seating portion;
• activating the second mesh electrode to generate a plasma field to treat the particles in the seating portion, the seating portion being configured to retain the particles during treatment in opposition to ionic winds resulting from the plasma field;
• and
• pouring treated particles out of the seating portion and the gap following the treatment.
