<p>A batch-type drying furnace (10) wherein an infrared heater (30), which has a filament (32) that radiates infrared rays when heated, can be moved in the front-back direction by means of a movement device (60) during the drying of a coating film (82) by the infrared heater (30), so as to change the position of the highest-energy portion of the coating film (82), that is, the portion for which the radiant energy of the infrared rays arriving from the infrared heater (30) is the highest. The movement device (60) changes the closest position of the coating film (82), that is, the portion closest to the filament (32). Furthermore, the movement device (60) moves the infrared heater (30) in a direction which is not the approach direction (the up direction) nor the separation direction (the down direction) of the infrared heater (30) and the coating film (82).</p> |
