  • Apparatus and continuous process for drying of dielectric materials
    Patent number: 5420404
    Abstract: An apparatus and method for drying, by heating, a continuous supply of dielectric material. A terminated, quarter-wavelength transmission line is used as a "traveling wave" applicator for transferring electromagnetic energy from a radio-frequency generator to the dielectric material as the material passes through the transmission line, preferably by gravity feed. The transmission line applicator is directly connected to the output of the radio-frequency generator, without any intervening feeding transmission line, so that the transmission line applicator becomes the resonant output tank circuit of the generator and thus determines the oscillation frequency of the generator. Forced air may be blown through the dielectric material as it flows through the transmission line so as to sweep moisture, driven to the surface of the dielectric material by heating, from the flowing dielectric material.
