Patent ID: 11369937

Abstract:
An apparatus for exposing a bulk volume of particles, such as free-flowing or semi-flowable grains, ore, or powders, or a non-flowing mass such as sewage or wet-chopped bio-mass so all of the particles receive near-uniform exposure to a radio frequency (RF) electric and/or magnet (EM) field, preferably without any preference of exposure to a surface or side of particulate. The invention relates to an antenna that can be metallic or plasma for transmitting RF EM radiation into a mechanical mechanism used to convey, or preferably to mix a bulk volume of particles. Embodiments of the apparatus include the ability to adjust the level of EM radiation comprised of one or more frequencies between 30 Hz and 30 EHz to regulate either or both the magnitude of temperature rise and the rate of temperature rise, or to regulate either or both the magnitude of chemical reaction, or rate of reaction.
