Problems solved by technology

However, due to the large difference between the equipment of the feeder and the flavoring machine, it cannot be directly extended to the feeder. Secondly, the invention does not take into account the different control methods of the damper when the equipment is in different production states.
Application No. CN201120245688.1 Chinese Invention Patent discloses a drum-type flavoring machine or feeder fan moisture exhaust system through a PLC programmable controller to send a frequency signal to the frequency conversion moisture exhaust fan to change the air volume of the frequency conversion moisture exhaust fan. Realize the reduction of the loss of the atomized feed liquid, make the smoke material flavored and fed more evenly, and do not solve the demand for the tidal exhaust air volume in different production states of the feeder
The Control of Tobacco Moisture Content in Thin Plate Cylinder Dryer Based on Exhausted Air Volume disclosed by Yang Shaohua et al. in the third issue of "Tobacco Science and Technology" in 2015 uses the adaptive PID expert control strategy of the tide exhaust damper to realize the control process. Through the PID value setting, To prevent the moisture content of shredded tobacco from overshooting and fluctuating, this method can only ensure the moisture content of shredded tobacco, and cannot promote the control of the outlet temperature of shredded tobacco. A drum-type shredded drying based on moisture balance is disclosed in the Chinese invention patent of application number 201810681621.9 The invention is based on the principle of moisture balance, and according to the obtained data, calculates the theoretical value of the moisture exhaust air volume of the shredded shredded tobacco machine, and adjusts the operating frequency of the fan of the shredded shredded shredded machine in real time, so that the current dehumidified air volume of the shredded shredded machine is equal to The theoretical value of the tidal discharge air volume remains consistent, but the invention does not involve the adjustment of the tidal discharge damper, and the adjustment process does not cover all the production and operation states of the entire tobacco feeder
[0004] To sum up, the existing inventions and researches on the control of the moisture exhaust damper of the feeder do not cover all its production and operation states. In the actual production process, the moisture exhaust damper of the tobacco feeder uses different dampers in different production stages. The control strategy can better ensure the constant temperature and moisture of the outlet smoke, so the invention of a moisture exhaust damper control device and method based on the production status of the tobacco feeder is of great significance
