PROBLEM TO BE SOLVED: To provide a drier that can be efficiently operated on the basis of a stable and accurate humidity.SOLUTION: A drier 1 dries objects to be dried 2 while circulating hot air in a drying chamber 3 using an air blower 4 and partially replacing the circulating air. A temperature in the drying chamber 3 is kept at a predetermined temperature by controlling a heater 5 on the basis of a temperature detected by a temperature sensor 14. If a humidity detected by a humidity sensor 15 provided in an exhaust stack 13 is kept continuously below a predetermined value for a predetermined time, the output of the air blower 4 is reduced, or the air blower 4 is stopped, or the discharge of air to the outside is stopped. |
