Abstract
PURPOSE: To enable assured cooling operation after heating operation by comparing the electric signals corresponding to the temperatures of outside air fed into a drying room and of exhaust air which has been used for drying and by controlling a heater.
CONSTITUTION: A drier casing 1 incorporates a rotary drum type drying room 2, exhaust wind duct 12, suction fan 13, heater 10, hot wind duct 9, and heat-sensitive element 25. The resistance of the heat-sensitive element 25 increases with rising exhaust air temperature during operation. When the difference between the outside air temperature and exhaust air temperature has reached a drying complection value, a differential amplifier 31 generates a signal of positive potential so as to cut off the circuit of the heater 10. With the exhaust gas temperature lowered by cooling operation, the amplifier 31 generates a signal of positive potential so as to stop the operation of the drier. Thus cooling operation is conducted assuredly after heating operation.
