MINGHUNG
Wet wood chips are continuously fed into the rotating drying drum through the feeding device. The drum interior features specially designed lifting plates that continuously lift and scatter the chips during rotation, ensuring full contact with high-temperature hot air from the hot air furnace. The hot air and wet chips undergo co-current or counter-current heat exchange inside the drum, with moisture rapidly evaporating and being discharged with exhaust gases. The dried chips are continuously discharged from the outlet end for the next production stage. The entire drying process—including temperature, feeding speed, and drum rotation speed—is monitored and adjusted in real-time by the control system to ensure consistent drying results.
Core Features
1. Ultra-Large Processing Capacity
Featuring a large-diameter, long-drum design, a single unit can process 10-30 tons of wet chips per hour (depending on raw material moisture content and type), meeting the raw material requirements of production lines with annual outputs of 50,000-200,000 cubic meters.
2. Truly Continuous Production
The entire process of feeding, drying, and discharging operates continuously without interruption, with no batch intervals. High production efficiency enables 24/7 continuous operation, significantly improving overall production line capacity.
3. High-Efficiency Energy-Saving Design
High-efficiency insulation layer structure minimizes heat loss
Hot air recirculation technology with high waste heat recovery
Optimized drum aspect ratio and lifting plate layout improves heat exchange efficiency by over 30%
Comprehensive energy savings of 20%-35% compared to conventional models
4. Precise Moisture Content Control
Equipped with online moisture detectors and PLC intelligent control systems that monitor output moisture content in real-time, automatically adjusting hot air temperature and feeding speed to ensure finished chip moisture content remains within process requirements (±0.5% accuracy).
5. Broad Raw Material Adaptability
Capable of processing various wood chips, sawdust, wood shavings, bamboo chips, crop stalks, and other biomass raw materials, with excellent drying performance across different initial moisture contents (30%-65%).
6. Sturdy Construction, Stable Operation
Drum manufactured from high-quality boiler steel plate, wear-resistant and corrosion-resistant
Heavy-duty carrying rollers and transmission system for smooth and reliable operation
Key components from renowned brands ensure low failure rate
Design service life exceeds 15 years
