Working Principle
Wet density board fibers are evenly fed into the continuous drying drum via a belt conveyor. The inner wall of the drum is equipped with specially designed lifting plates, which repeatedly lift and disperse the fibers as the drum rotates, ensuring full contact with high-temperature hot air from the hot air furnace. Moisture is rapidly evaporated, and the exhaust gases are discharged after two-stage purification through a cyclone dust collector and a bag filter. The dried fibers are continuously discharged through a rotary airlock to the next process. The entire line is automatically controlled by a PLC central control system, which adjusts feeding speed, drum rotation speed, hot air temperature, and airflow, enabling fully unmanned continuous production.

Key Advantages
1. Fully automatic continuous operation: Stable 24/7 production without frequent manual intervention, significantly reducing labor costs.
2. High drying uniformity: Optimized lifting plates and air duct design ensure outlet moisture deviation ≤1%.
3. Outstanding energy saving: Hot air recirculation + waste heat recovery reduce energy consumption by 25%-35% compared to traditional batch dryers.
4. Eco-friendly emission compliance: Two-stage dust removal + sealed design, dust emission concentration ≤20mg/Nm³.
5. Intelligent self-adaptation: PLC automatically matches feed rate, temperature, and drum speed to adapt to fluctuations in raw material moisture.
6. Easy maintenance: Modular design of key components allows quick replacement of wear parts, minimizing downtime.
