 How effective is our dryer?

• Moisture content before drying: typically 50–60%.after drying,the core veneers moisture is 8–12% and variation within the same batch is within ±2%.

• the veneers quality remain flat, warp-free, and crack-free after drying.

  Why Choose the Roller Type Dryer?

• Fast Dryiny:Multi-layer design (4, 5 layers, etc.) handles large volumes,and rollers keep veneer sheets moving evenly for quick and continuous drying.
• Even Results: veneer Sheets are pressed and heated evenly, reducing warping and cracks,the stable temperature and humidity ensure uniform moisture content.
• Space-Saving: multi-layer roller dryers takes less floor space, perfect for big production lines.
• Easy to Use:Automatic feeding, temperature control, and airflow adjustment,Less manual work, easier to operate and maintain.

Who Should Use the Roller Dryer?

1. High-Output Manufacturers

• Ideal for factories that need to dry large volumes of veneer quickly,for Multi-layer design greatly boosts productivity.

2. Thick or Hard Wood Processors

• Perfect for drying thick or hard veneer that easily warps or cracks, for Roller pressure and even heating keep sheets flat and consistent.

3. Quality-Oriented Plywood Producers

• For companies that demand uniform thickness, smooth surface, and stable moisture content,Ensures superior veneer quality with minimal defects.

4. Enterprises with Investment Capacity

• Although the machine requires higher investment and maintenance, it delivers long-term efficiency and cost-effectiveness.

5. Continuous Production Line Users

• Best for plants running full production lines with peeling, gluing, and pressing,High automation reduces labor and increases overall efficiency.

Why Roller Dryers Are Suitable for Core Veneer?

1. Thicker Veneer with Higher Moisture

   • Core veneer is usually thicker (above 1.2 mm) with an initial moisture content of 50–60%.It requires stronger pressure and higher temperature to prevent cracks and deformation.

   • The roller dryer presses and flattens the veneer between rollers, keeping it straight and ensuring even heat and moisture removal.

2. High Drying Efficiency

   • Core veneer is needed in large quantities.Multi-layer roller dryers run continuously with high speed and large capacity, meeting mass production demands.

3. More Stable Quality

   • With veneer clamped between upper and lower rollers, warping and cracking are minimized.This ensures flatness and consistency, meeting the high-quality requirements of plywood production.

Why Mesh-Belt Dryers Are Suitable for Face Veneer?

1. Thin and Fragile Veneer

   • Face veneer is very thin (0.2–1.5 mm) and weak.If pressed by rollers, it can easily break. Also, due to gaps between rollers, ultra-thin veneer cannot be transported smoothly.

   • On a mesh belt, veneer lies flat and moves forward without stretching or breaking, keeping it intact.

2. Gentle Drying

   • Face veneer usually has lower moisture content.Mesh-belt dryers use steady airflow and mild heating, which is better for soft and gentle drying.
