Abstract: Automatic control of the drying process is a crucial means of achieving drying objectives. It plays a vital role in ensuring uniform moisture content of the discharged material, improving material quality, reducing labor intensity and optimizing dryer performance. Aiming at the control requirements of dryers for material drying, a temperature control scheme for the dryer was proposed and optimized. Meanwhile, based on in-depth research on the fuzzy PID control algorithm, a temperature control system for ribbon dryers based on fuzzy PID control was designed, and the overall dryer control system was implemented through a PLC system. This solution can ensure material drying quality while enhancing equipment automation and production efficiency, delivering superior control performance. The research outcome facilitates determining optimal process parameters for material production, improving product consistency and quality.
