Abstract
One aspect is a material drying system with a conductive bin at least partially filled with harvested material. A frequency generator is configured to generate radio frequency energy and a controller is coupled to the frequency generator for controlling the radio frequency energy. At least one conductive shape located within the harvested material and coupled to the frequency generator and controller. The frequency generator and controller provide the radio frequency energy to the at least one conductive shape such that a system capacitor is formed by the combination of the at least one conductive shape and the conductive bin and with harvested material forming a dielectric therebetween such that friction of water molecules in the harvested material is induced quickening drying thereof.
IPC Classes ?
- F26B 3/347 - Electromagnetic heating, e.g. induction heating or heating using microwave energy
- F26B 3/34 - Drying solid materials or objects by processes involving the application of heat by development of heat within the materials or objects to be dried by using electrical effects
- F26B 9/06 - Machines or apparatus for drying solid materials or objects at rest or with only local agitation; Domestic airing cupboards in stationary drums or chambers
