    Abstract: A system for dehumidifying and drying a powdered or granular material having a drying hopper, a dehumidifying unit, and a circulation route having a processing gas supply route and a processing gas dehumidifying route that interconnect the drying hopper and the dehumidifying unit to allow processing gas to circulate is proposed. The system repeatedly supplies and circulates the processing gas in the circulation route. The processing gas supply route and the processing gas dehumidifying route are interconnected by a bypass route having a regulation valve. A temperature sensor for detecting the temperature of processing gas exhausted from the drying hopper is installed in the processing gas dehumidifying route. The system further has a control means for controlling opening or closing of the regulation valve, provided in the bypass route, based on a temperature detection signal detected by the temperature sensor.
