Equipment Structure and Working Process
This equipment consists of six main parts: the feeding conveying system, multi-layer tunnel drying chamber, hot air generation and circulation system, dehumidification system, discharge cooling system, and electrical control system.
Veneer or plywood to be dried is fed layer-by-layer onto each conveying mesh belt via an automatic feeding device;
The boards move forward at a constant speed within the tunnel while high-temperature circulating hot air penetrates from both top and bottom;
Moist air is forcibly discharged by dehumidification fans, while fresh hot air is continuously supplemented;
After drying, the boards pass through a cooling zone at the discharge end and are automatically stacked after natural cooling.
Core Technical Advantages
Multi-layer Synchronous Drying: Standard configuration includes 3 to 8 independent conveying channels, allowing simultaneous drying of multiple boards in a single pass, significantly multiplying production capacity.
Rapid and Uniform Drying: Adopts top-and-bottom opposed hot air blowing structure for even airflow distribution, ensuring consistent heating on both sides of the boards, eliminating defects such as warping, cracking, and color variation.
Precise Temperature and Humidity Control: Each layer is independently monitored for temperature and humidity with PID automatic adjustment. The drying curve is precisely controllable, with finished moisture content stably maintained between 6% and 12%.
High Efficiency and Energy-Saving Design: Fully enclosed insulated drying tunnel combined with a heat recovery system achieves a thermal efficiency of over 85%. Variable-frequency drive motors operate on demand, reducing unnecessary power consumption.
Quick Start-up and Easy Maintenance: Short preheating time, rapid cooling after shutdown, and an internal structure that facilitates cleaning and maintenance, minimizing downtime.
