Claim:
A drying machine equipped with a storage chamber to store a matter to be dried, and a heat pump in which a refrigerant circuit is constituted of a compressor, a radiator, expansion means and an evaporator, a refrigerant discharged from the compressor being passed through the radiator, the expansion means and the evaporator, and air being circulated from the radiator to the evaporator through the storage chamber, whereby the matter to be dried is dried in the storage chamber, the drying machine comprising: heat discharge means for removing heat from the refrigerant which enters the expansion means; and control means for variably controlling a discharged heat amount in the heat discharge means and capacity of the compressor, wherein the control means has at least two kinds of drying modes including a usual drying mode and a delicate drying mode, and in the delicate drying mode, a temperature of the air discharged into the storage chamber is set lower than in the usual drying mode to control the capacity of the compressor and to increase the discharged heat amount in the heat discharge means.
