たことを特徴とする乾燥機。 A heat exchanger capable of flowing a liquid through a primary flow path, and supplying air that is passed through a secondary flow path of the heat exchanger and has exchanged heat with the liquid passing through the primary flow path to a drying chamber, In the exhaust path from the drying chamber,
The exhaust gas from the drying chamber is caused to flow into the secondary flow path of the heat exchanger and circulated to the drying chamber, and the exhaust gas is discharged outside the machine and outside air is caused to flow into the secondary flow path of the heat exchanger. A dryer characterized by being equipped with a valve device that switches between the two states.
