  • Radiofrequency heating of wood using a three-electrode system having a winged central electrode
    Patent number: 12498172
    Abstract: Wood kilns, electrode systems for wood kilns, and methods of using the systems for the radiofrequency (RF) drying and phytosanitizing of wood are provided. The electrode systems are based on a three-electrode design in which a central plate electrode having winged edges is disposed between a pair of ground plate electrodes. The winged edges of the central electrode improve the uniformity of heating during the phytosanitizing process, relative to a five-electrode parallel plate system, or a three-electrode parallel plate system having a conventional planar central plate electrode.
    Type: Grant
