<p>PROBLEM TO BE SOLVED: To provide a dryer capable of optimizing the time consumed for reproduction processing of an adsorber.SOLUTION: In drying processing for drying granules, a drying/production blower 7 is driven to rotate in a normal direction, and air dehumidified by an adsorber 9 and heated by a heater 10 is supplied from an air circulation line 8 to a drying hopper 2 through an air supply pipe 6. Consequently, the granules have water adsorbed to become dry. In reproduction processing for reproducing the adsorber 9, the drying/reproduction blower 7 is driven to reverse, and air heated by the heater 10 circulates through the adsorber 9. Consequently, the water adsorbed by the adsorber 9 is removed and the adsorber 9 is reproduced into a moisture absorbable state. Then the reproduction processing ends at a certain time after the temperature of the air circulating through the adsorber 9 reaches a target temperature.</p> |
