 | Product Introduction |
The roller structure of Alva's Roller Veneer Dryer has undergone precision processing and temperature calibration, which can exert uniform and gentle pressure and heat on veneers, thereby achieving a natural smoothing effect.
This integrated design of "drying + shaping" ensures that the processed veneers not only have a smooth and flat surface (completely eliminating the micro-warpage remaining after peeling) but also their moisture content can be accurately controlled within the process-required range, avoiding problems such as local over-drying or insufficient drying.
During the transportation of veneers by the rollers, when the veneers are between two sets of relatively rotating rollers, there is no rigid constraint on the transverse direction of the boards, allowing them to shrink freely with moisture evaporation.
This feature can effectively relieve the stress concentration inside the wood caused by changes in temperature and humidity, fundamentally reducing the risk of defects such as cracks and splits, and providing stable and high-quality base materials for the subsequent gluing process.
In terms of adaptability, the equipment has a clear applicable range for veneer thickness, and is generally more suitable for drying veneers with a thickness of 1mm or more—overly thin boards are prone to damage due to the pressure of the rollers.
In terms of feeding method, the equipment adopts a longitudinal feeding design, which requires that the wet veneers after peeling must first undergo precise cutting to adjust them to specifications that match the equipment's feeding size before they can smoothly enter the drying process, ensuring the stability of the transportation and drying process.

| Product Advantages |
Efficient production
High adaptability and large production capacity: Precisely match the single board size of the plywood industry (such as 48 feet, 36 feet), a large single loading volume (taking 48 feet single board as an example, 30 layers can be placed at a time, 16 pieces per layer), a single drying takes only 30-40 minutes, and the processing volume per hour reaches 1-1.2 cubic meters, which meets the rhythm of large-scale production.
Automation integration: It can be configured with a fully automatic high-speed palletizer + robot, without manual operation throughout the process, greatly improving production efficiency and reducing dependence on manpower.
Quality assurance
Uniform drying and anti-deformation: The scientific hot air circulation design (such as upper and lower bellows nozzles) is adopted to make the veneer evenly heated to avoid cracking, carbonization, warping and deformation. After drying, the veneer has high flatness and the average moisture content is precisely controllable (such as 0-8 degrees), laying a solid foundation for high-quality plywood.
Adaptable to various raw materials: It can handle veneers of different materials (such as eucalyptus, pine, etc.) and thicknesses, and adapt to various production needs by adjusting the drying parameters (feeding speed, temperature, etc.).
Highly Intelligent and Easy to Use
Precise temperature control: The independent modular drying room design, combined with high-precision temperature detection instruments and dynamic frequency conversion control, can flexibly adjust the optimal drying temperature according to the moisture content of the board and process requirements to ensure the uniform consistency of the drying effect.
Easy to operate: Supports smooth infinitely variable speed and user-friendly custom parameter settings to simplify the operation process; with an intuitive visual interface, it is easy to monitor the drying status in real time and promptly adjust the process in time.
