Roller veneer board drying line utilizes the latest international technology of pressurized contact veneer plywood drying, which has the advantages of simple operation, safety and practicality, stable operation, easy maintenance, hot-pressing-levelling--drying once completed, etc. The use of hot air circulation has greatly reduced the operating costs of enterprises, improved the quality of sheet materials and increased the production volume. The roller plays a role in ironing the veneer. After the veneer is dried by roller veneer board drying line, the veneer is flat and the moisture content is relatively uniform. When the veneer is located between two roller sets, the lateral direction can be freely contracted, the occurrence of cracks is reduced, and the drying quality is good. The heat dissipation process is carried out in a flat state. In the benign physical process of wood shrinkage, the veneers do not warp and deform, the breakage rate is low, and the yield rate is high.
The traditional dryer is easy to drop chain, card chain, veneer deviation, heat exchange device is easy to plug. These will result in low thermal energy utilization and poor product uniformity. Moreover, its transmission device is complex and maintenance is difficult, which virtually increases the production cost.
