A drying device (1) for powdery and granular materials has a drying hopper (21) for storing powdery and granular materials, a blower (15) and a heater (26) for supplying heated gas to the drying hopper, and includes: first The temperature detection sensor (44) detects the temperature indicating the drying process state of the powdery and granular materials in the drying hopper; the second temperature detection sensor (45) detects the temperature of the gas after passing through the heater; the control mechanism (41) , when the detected temperature of the first temperature detection sensor is higher than the preset first threshold, the heater is stopped, and further, in the stopped state, the detection temperature of the second temperature detection sensor is lower than the preset third threshold. At the second threshold, the air blower is stopped, and then, when a predetermined first time has elapsed since the heater was stopped, the heater and the air blower are started.
Description
technical field [0001] The present invention relates to a method for drying powder and granular materials and an improvement of a drying device for powder and granular materials. The gas blown from a blower is heated by a heater and then supplied to a drying hopper in which powder and granular materials are stored. Thereby, the powder and granular material is dried. Background technique [0002] In the past, the following drying device for powder and granular materials is known. The drying device for this powder and granular material is equipped with: a drying hopper for receiving powder and granular materials; a drying blower (blower, air blower) for blowing dry gas to the drying hopper. and a heater (heater) for heating the drying gas blown to the drying hopper. In such a drying device, outside air is taken in by a blower, heated by a heater, supplied to the drying hopper, and passed through the layer of powder and granular materials stored in the drying hopper, and then ...
