Veneer Dryer Plywood Drying Machine

What is plywood dryer

The principle of the veneer dryer is to use the moist and hot air in the heating chamber of the dryer to discharge the water from the green veneer to achieve the desired moisture content. Why do you need to remove excess moisture from the veneer? Because too wet plywood processing will bring a series of problems. Excessive moisture in the plywood can affect the glue bonding of the plywood gluing process. High humidity veneer is also not suitable for the hot-pressed plywood manufacturing process. This will prolong the hot pressing time and reduce the quality of the sheet. Follow-up is also prone to foaming, permeation, degumming, etc.

Controlling the speed, temperature and humidity inside the dryer at optimum levels during drying of veneers will make the wood dimensionally stable, relatively consistent in moisture content, free from pests and easy to store. The finishing and processing of the plywood will also be of a higher quality. Good veneer drying practices are necessary to make high-quality plywood.

The dryer is composed of feeding line, heating chamber, cooling chamber and infeeding line.

Feeding system for drying machine

Our feeding system is matched according to customer automation requirements.It can be semi-automatic, automatic or manual feeding. We recommend suitable feeding methods based on meeting specific veneer production requirements.The degree of automation can consider the output, labor and other factors.

Semi-automatic dryer

Semi-automatic feeding plate uses vacuum assist system to suck wet plate, usually only 1 to 2 people to cooperate with the feeding plate process.When the working width is relatively wide, we can consider 2 people with the board into the process, 2 people distribution on both sides of the division of labor cooperation will be uniform wet plate into the dryer inside.Semi-automatic with manual assistance can efficiently meet the required feeding speed, perfect coordination can achieve the whole width of the dryer and uniform drying veneer on all decks.

Plywood machine with automatic feeding

Automatic feeding is the latest and most efficient feeding plate process.It has high requirements for vacuum assist system, feeding speed and equipment.If there are high quality requirements of veneer, save labor costs, accustomed to the use of automatic customer groups, automatic board is undoubtedly the best choice.Fully automatic is most suitable for high output, high degree of automation of the whole line of equipment in the factory planning.The vacuum assist system lifts the wet veneers and delivers them to the dryer at a high feed rate.

Manual feeding dryer

Manual into the board is completely dependent on manual operation.The whole process of plate feeding is simple to the technical requirements of the equipment, and only requires workers to repeat the mechanical plate.Usually need 4 to 5 people to match the speed of the board, evenly distributed before the board frame.This is a negligible cost for a factory with abundant human resources.For the purchase of equipment for a long time, the equipment is still old and has not been updated, the whole line of equipment partial automation degree is low, the purchase of the manual feed plate is also appropriate.If you recently consider upgrading, slowly replace the previous equipment, in fact, you can consider semi-automatic into the board.

The choice of the degree of automation of the board is often determined by many factors, such as the degree of automation of the whole line of equipment, output, human resources, the quality of the board and so on.
