Roller-Type Veneer Dryer
Roller-Type Veneer Dryer
The Roller-Type Veneer Dryer is a high-efficiency continuous drying system designed for plywood and wood-based panel production. It uses advanced hot air circulation and roller transmission technology to rapidly reduce veneer moisture content while maintaining flatness and structural integrity.
This machine is widely used in modern plywood manufacturing lines to ensure consistent drying quality, improve bonding performance, and enhance overall production efficiency. By precisely controlling temperature, humidity, and airflow, the dryer produces uniform, high-quality veneer sheets suitable for further processing.

Roller-Type Veneer Dryer
1. Product Detailed Description
The Roller-Type Veneer Dryer operates through a continuous conveyor system of upper and lower rollers, which transport veneer sheets through heating and cooling zones. Hot air is evenly distributed across both sides of the veneer, ensuring rapid and uniform moisture removal.
Working Principle
- Veneer enters the preheating section
- High-temperature air (typically 140–200°C) is applied via circulation fans
- Rollers press and convey veneer steadily through drying chambers
- Cooling section stabilizes the veneer before discharge
This continuous drying method significantly improves productivity compared to traditional batch drying.
Structural Components
- Roller conveyor system (steel tube rollers)
- Heating chamber (hot air / biomass / steam / thermal oil)
- Air circulation and exhaust system
- Cooling section
- Automatic control system (PLC + touchscreen optional)
- Feeding and discharging conveyors
