There is disclosed in the present application a method and apparatus for treating variable batches of moist dielectric materials by the application of radio frequency energy which reduces the moisture content. According to the present method and by the use of the present apparatus full, power or another pre-determined power level from a radio frequency power source is maintained on the load by an electro-mechanical adjusting device which incrementally reduces the coupling between the source and the load until the boiling point of water is reached. After the boiling point is reached, the coupling is incrementally increased to reach a pre-determined moisture content in the material being …
