<p>PROBLEM TO BE SOLVED: To provide a drying device that can efficiently save energy.SOLUTION: A drying device 1 comprises: a storage hopper 13 that stores powder and granules; and a dry air supply part 12 that supplies dry air into the storage hopper 13. The dry air supply part 12 is provided with: an adsorption member 25 that adsorbs moisture contained in the air supplied into the storage hopper 13; a regeneration device 26 that removes the moisture adsorbed by the adsorption member 25; an exhaust line 31 that discharges exhaust air including the moisture removed from the adsorption member 25 by the regeneration device 26; and a second temperature sensor 32 that measures the temperature of the exhaust air. The operating quantity of the regeneration device 26 is increased on the basis of a decrease in the temperature of the exhaust air, and the operating quantity of the regeneration device 26 is decreased on the basis of an increase in the temperature of the exhaust air.</p> |
