PURPOSE:To secure safe operation, by calculating the concn. of the solvent in each region within a drying oven from the solvent evaporation curve of a paint to be used and the temp. rising speed of a treating material and setting the exhaust gas corresponding thereto. CONSTITUTION:Each zone is connected to an incinerator 7 form furnace exhaust gas pipings 5a-5e through a blower 6 and the solvent evaporation gas of a paint is incinerated. A heat exchanger 9 preheats clean air tanken in by a blower 11 and preheated air is blown to each zone of a drying oven 4 by recirculation blowers 12a-12e. The plate passing speed of a treating material 2 is set to a treatment speed and the furnace exhaust dampers 18a-18c of exhaust gas pipings 5a-5c are regulated by regulators 19a-19c corresponding to the output of a detector 16 for detecting the number of rotations of the take-up roll of a roll coater 3 and the outputs of detectors 17a-17c of the furnace exhaust gas flow amounts of furnace exhaust gas pipings 5a-5c.
