PROBLEM TO BE SOLVED: To provide an energy-saving drying machine which prevents liquid backflow, shortens time required until a freezing cycle gets into a steady state and significantly shortens time required for drying. SOLUTION: The drying machine 100 has a drying chamber 110 storing dried objects, a refrigerant circuit 160 sequentially circularly connecting a compressor 120, a heat dissipator 130, a decompressor 140 and a heat absorber 150 by pipes, an air circulation route 170 in which air in the drying chamber 110 exchanges heat with the heat dissipator 130 and the heat absorber 150 and circulates, an air circulation means 180 provided in the air circulation route 170 and to circulate air. At least a part of the piping from the decompressor 140 to the compressor 120 of the refrigerant circuit 160 is provided in the air circulation route 170 and a heating means 190 is provided in the air circulation route 170.
