The plywood industry plays a vital role in global economic development as it provides cost-effective, stable and reliable materials for a variety of commercial applications. It consists of thin or multiple layers of wood veneers held together with glue. Veneer drying is a critical step in the production of high-quality wood products, including plywood, furniture and flooring. However, the quality of plywood depends largely on the ability of these woods to dry. Hot Press Type Veneer Dryer Machines are the perfect solution for the drying process.
Introduction to plywood veneer drying
Before we delve into the benefits of hot-pressed plywood dryers, let’s take a brief look at veneer drying. Plywood is made by gluing veneers together during the manufacturing process. They are composed of thin sheets of wood, typically between 2.5 and 4 mm thick.
Once the veneers are sliced, they contain a lot of moisture that needs to be removed before they can be glued together to form plywood. The drying process has a significant impact on the quality and durability of the final product. Inadequate or improper drying can cause plywood defects such as blistering, bending, lifting and cracking.
Traditionally, these wood sheets drying has been done in open-air systems, which require large land areas and take a long time. These methods are inefficient, time-consuming, and have poor quality control, resulting in inconsistent drying. However, as technology advances, plywood manufacturers now have access to hot-pressed plywood veneer dryers, this is an efficient and reliable solution.
Construction of the Hot Press Type Veneer Dryer Machine
Mainly consists of the following parts:
- Feeding conveyor
- Veneer aligner
- Drying chamber
- Heating system
- Cooling system
- Discharge conveyor
One of the most crucial parts of the hot press type veneer drying machine is the drying chamber, which is designed to provide optimal heat and airflow. The drying chamber is divided into several sections, depending on the equipment size and capacity. Each section has its heating system and airflow control system, allowing the machine to achieve high efficiency in drying veneers of different thicknesses.
Hot pressed veneer dryer type
Divided into two types. Type A is a breathing type, and type B is a square tube.
Type A respiratory veneer dryer
All hot plates are switched off simultaneously, i.e. all boards can be dried at the same time. This prevents those boards from drying out too much on the top and too much on the bottom. At the same time, it can also remain flat, so the quality of plywood produced with this veneer will be very good.
In conclusion
In short, the hot-pressed plywood veneer dryer is an efficient and reliable solution for drying in the plywood industry. Its advantages include higher production efficiency, stable quality, environmental protection and cost-effectiveness. By choosing the right hot-pressed plywood veneer dryer, you will obtain high-quality, uniformly flat veneers that can be processed into plywood, LVL beams and other artificial panels.
