点を見いだすことができる。The exhaust hot air that has dried the object to be dried W in the drying chamber 1 is recovered from the lower part of the drying chamber 1 to the exhaust hot air circulation path 9. The hot air circulation path 9 is provided with a hot air blowing means 10 such as a fan, and circulates the hot air recovered from the drying chamber 1 to the hot air generating device 3 in the hot air blowing path 4. Although the temperature of the exhaust hot air that has dried the object to be dried W has dropped to about 175 ° C., the exhaust hot air blowing means 10 such as a fan has an exhaust hot air compressing function.
, The temperature rises by about 5 ° C, and the temperature is prevented from lowering. For this reason, the temperature of the exhaust hot air circulated to the hot air generator 3 is extremely small, and it is sufficient for the hot air generator 3 to provide the burner 4 with a small amount of heat energy sufficient to supplement the heat radiation from the circulation path. In addition, by adjusting the air volume of the motor that drives the exhaust hot air blowing means 10 by inverter control, it is possible to find an appropriate point for preventing the temperature of the exhaust hot air from lowering.
