To make a blowout air temperature be quickly close to a target temperature.
In this dehumidifying drying device, a first refrigerating cycle is composed of a compressor 31, a condenser 32, refrigerant expanding mechanism 34 and an evaporator 33, a second refrigerating cycle is composed of a compressor 35, an evaporator 37, a refrigerant expanding mechanism 38 and a condenser 36, the air sucked from an air suction port 42 is cooled/dehumidified by the evaporator 33, and then heated by the condenser 32 to obtain the dried air, the dried air is further cooled by the evaporator 37, the cooled dried air is sent to a dehumidified and dried object from an air blower 43, and the output of the compressor 35 is controlled so that the target temperature and the blowout air temperature are agreed with each other by the operation of an operating switch 47.
