Product Introduction
Why do wood veneers need to be dried in plywood production?
Wood veneers must be dried for the following key reasons:
1. To ensure sufficient bonding strength of the adhesive. High moisture content will weaken the glue bond, leading to delamination and blistering.
2. To stabilize the moisture content of veneers and prevent warping, twisting or deformation of the finished plywood.
3. To prevent mold, decay and discoloration during storage and processing.
4. To avoid board bursting or blistering caused by excessive moisture during hot pressing.
The standard moisture content for veneer in plywood production is generally 8%–12%.
Whats the difference of the Roller veneer drying line and the mesh belt veneer drying line ? | |
Roller veneer dryer machine 1.Fast speed ,high efficiency . 2.better veneer flatness and uniform moisture content 3.longer work life . 4.veneer thickness 1-4mm  | Mesh belt veneer dryer machine 1.veneer thickness 0.3-4mm ,Suit for face veneer and core plywood veneer. 2.Wide application 3. lower price 4. Face veneer only be dryed by mesh belt type  |
High-temperature-resistant stainless steel material   | Galvanized steel sheet filled with aluminum silicate  |
Product Advantage
Galvanized sheet metal, air pipes in saw tooth thread design prevents veneer jamming; Laser precision drilling ensures even heating of the veneers. The width is at 200mm, thickness is at 1mm. | Made with Die-cast aluminum finned tube. Heat Exchanger delivers high thermal efficiency with minimal heat loss. Provided that the customer's thermal oil heater supplies sufficient heat, the temperature difference between the oil inlet and the dryer remains within approximately 20°C, ensuring full drying production capacity. |
