A capacitive high-frequency drying system for drying moisture-containing material in which hot air is passed through the high-frequency oven is disclosed. For better energy utilization, the air is preheated by the waste heat of the high-frequency generator, and is conducted, after passing through the oven, through a heat exchanger for heating water for utility or industrial purposes.
