制御装置。[Scope of Claim for Utility Model Registration] (1) A hot-air oven that continuously supplies a film strip whose surface is coated and dries the film strip by supplying and exhausting the required amount of hot air. An air supply system equipped with an air supply damper, a circulation blower, a heater, and an air filter to circulate and supply hot air is connected to this warm air furnace, and an exhaust system equipped with an exhaust blower is connected to the air supply system to circulate and supply hot air. In a dryer configured to perform exhaust, an exhaust blower with a motor for variable speed control and a damper with a motor for controlling opening are arranged in series in the exhaust system, and a pressure transmitter for measuring the pressure inside the dryer is provided, and the pressure transmitter The pressure measurement value is compared with a predetermined pressure setting value, and if the pressure measurement value is outside the predetermined tolerance range with respect to the pressure setting value, the opening control motor is controlled according to the deviation to open the damper. If the measured pressure value is within a predetermined tolerance range from the pressure set value, the variable speed control motor is controlled according to the deviation, and the rotation speed of the exhaust blower is corrected to maintain the internal pressure inside the dryer. 1. An internal pressure control device for a dryer, comprising: a controller configured to maintain constant pressure. (2) In the internal pressure control device according to claim 1, an air supply damper with a motor for controlling the opening is provided in the air supply system, and a gas concentration meter is provided on the upstream side of the exhaust blower with a motor for variable speed control in the exhaust system, The controller is configured to compare the solvent gas concentration measurement value by the gas concentration meter with a predetermined solvent gas concentration setting value, and control the opening degree control motor according to the deviation to correct the opening degree of the supply air damper. An internal pressure/solvent gas concentration control device in a dryer.
