Radio Frequency

Industrial radio frequency is extensively used in the food processing, textile and wood processing industries. This technology provides very rapid product heating, which minimizes exposure of the commodity to elevated temperatures, thus perhaps mitigating injury. Another aspect of radio frequency heating is that the heat is generated by directly coupling electromagnetic waves with the material. This provides the possibility of targeting the pest within a range that has limited impact on its host.  Pilot scale RF systems were used in laboratory work. A large scale RF system was used for industrial scale testing, at Diamond Walnut Growers, Inc., in Stockton, CA.
