Abstract
Systems and methods for controlling drying of ceramic greenwares accounting for the load presented to a radio-frequency (RF) source of an RF applicator to reduce the risk of overheating greenware during drying. The method includes partially drying the greenware and then substantially drying the greenware with RF radiation. The RF radiation provided to an electrode region is controlled based on the number of greenware pieces within the electrode region at a given time. The system includes a control unit electrically connected to the electrode and configured to provide a select RF voltage to the electrode based on the number of greenwares within the electrode region. The system adjusts at least one input voltage from a power supply. The adjusted voltage is stepped-up, DC-rectified to form a plate voltage, and then converted by a high-frequency DC/AC convertor to the select high-frequency AC RF voltage needed to dry the greenwares without overheating.
