<P>PROBLEM TO BE SOLVED: To provide a drying device capable of suppressing oxidation at low costs. <P>SOLUTION: This drying device is provided with a deodorizing device 50 comprising an oxidation catalyst 52 and a heater 53 for heating the oxidation catalyst 52 and disposed in a ventilation flue 17A, a seal means 15 disposed on a door 14 and capable of air-tightly closing the door 14, a trap portion 44 capable of closing a drain pipe 43, and a plug body 60 air-tightly closing an internal drain outlet 58, and the deodorizing device 50 is operated in a state of air-tightly blocking the inside of the main body 10 from the external by the seal means 15, the trap portion 44 and the plug body 60. The amount of oxygen in the air-tight main body 10 is constant amount decided by a volume in the main body 10, oxygen concentration in the main body 10 is gradually lowered in accompany with the progression of oxidative decomposition of an odor component by the deodorizing device 50. <P>COPYRIGHT: (C)2009,JPO&INPIT |
