Plywood is an engineered wood widely used in construction, furniture manufacturing and packaging. It is made by gluing together thin layers of wood veneer that are stripped from logs using a rotary veneer lathe. One of the key processes in producing high-quality plywood is drying the veneers before gluing them together. The plywood veneer dryer production line is an important tool to achieve this process efficiently and effectively.
What is a plywood veneer dryer production line?
It is a set of machines specifically designed to dry veneers used in plywood production. It consists of veneer feeding system, hot air circulation system, moisture removal system, control system and other parts. The veneer feeding system is responsible for feeding the veneers into the dryer, while the hot air circulation system generates heat to remove moisture from these panels . Moisture removal systems remove moist air from the dryer and create a controlled environment for the drying process. Finally, the control system regulates the dryer temperature and humidity levels to ensure optimal drying conditions for these panels.
Why do we need dry veneer?
1. Stable single board
Wood is a hygroscopic material, which means it absorbs moisture from the environment, causing it to change in size and shape. Therefore, when wood is used in wet conditions, it expands or contracts, causing warping, cracking, or splitting. Drying veneer stabilizes it, preventing it from warping, cracking, or splitting when temperature or humidity changes.
2. Prevent rot
Drying veneer removes excess moisture from the wood, creating an environment that is not conducive to fungal and microbial growth. As a result, it is less susceptible to rot, allowing it to last longer and maintain its quality.
3. Improve wood quality
Wet wood is less dense than dry wood, reducing the wood's hardness and durability. Drying veneer increases its density, improving its strength, hardness and durability.
4. Lose weight
Wet wood is heavier than dry wood, which can be a disadvantage during shipping and handling. Drying these panels reduces the weight of the wood, making it easier to manage during shipping and handling.
Application of veneer dryer production line
It is widely used in the plywood manufacturing industry. Suitable for producing various types of them including:
1.Softwood plywood
It is made from softwood logs such as pine, fir, and spruce. It is commonly used in construction, furniture and packaging.
2. Hardwood plywood
It is made from hardwood logs such as birch, oak, and maple. It is commonly used in high-end furniture, decorative fixtures, and musical instruments.
3. Decorative plywood
It is made by applying a thin layer of hardwood veneer on top of a base board, usually made of softwood plywood. It is commonly used in interior design, cabinets and furniture.
In conclusion
The plywood veneer dryer production line is a key component in producing high-quality plywood. It provides a faster, consistent and efficient drying process, resulting in increased productivity, lower costs and fewer defects. Fuzhou Mutian offers several different Wood veneer dryer machine which is suitable for different plywood production process.
