PURPOSE:To properly control a drying operation time by automatically discriminating the actual drying condition of an article to be dried and executing the completion of the operation. CONSTITUTION:The relative humidity of air to flow into a drying room 10 is lowered by a drying means 23. The room temperature of the drying room 10 is detected by a room temperature detecting means 28, and the temperature of an article 35 to be dried is detected by a dried article temperature detecting means 29. An operation control means 13 stops the operation of the drying means 23 when a temperature difference, in which a detected temperature by the dried article temperature detecting means 29 is subtracted from the detected temperature by the room temperature detecting means 28, is made into a reference value or below. |
