<P>PROBLEM TO BE SOLVED: To provide a drying device using a heat pump device, configured to maintain high thermal efficiency and enable stable operation even when temperature and an air volume of dry air are frequently changed. <P>SOLUTION: External air a is sucked by a blower fan 34 from an air intake port 31 disposed at one end of a second dry air supply passage 30, and heated by a condenser 404 of a heat pump device 40. The heated dry air is supplied to a first dry air supply passage 14. The dry air is supplied by supply fans 22a to 22c disposed in the first dry air supply passage 14 into drying chambers 16a to 16c of a drier 12. A difference between the air volume of the blower fan 34 and the air volume of the supply fans 22a to 22c is tolerated by suction or discharge of air through an air release port 28. The air volume of the blower fan 34 is controlled by a controller 82, on the basis of detection values of a flow volume sensor 78 and of a temperature sensor 80. <P>COPYRIGHT: (C)2013,JPO&INPIT |
