Roller veneer dryer: It uses a series of upper and lower rollers to convey the veneer through the dryer. All the lower rollers are driven by a motor through a transmission device through a chain, while the upper rollers are driven by the lower rollers through a pair of long-toothed gears. Therefore, the upper rollers can be used with different veneer thicknesses float up and down within a certain ...

Hot plate veneer dryer: used for drying the thick veneer manufactured by LVL, usually the roller dryer is used first, and then the hot plate dryer is used. This process can not only ensure the quality of the veneer, but also improve the efficiency of veneer drying. The host structure of the hot plate dryer is basically the same as that of the ordinary plywood hot press machine. In order to shorten...

The purpose of wood debarking is mainly to facilitate rotary cutting and improve the quality of veneer. The bark is generally composed of outer bark, phloem and cambium. Because the structure of bark is completely different from that of wood (xylem), bark is not only useless in plywood production, but also because its phloem is mostly composed of elongated fibers, if the wood section is directly p...

Various defects are prone to occur during the wood peeling process of veneers, so there are veneer quality problems. The quality of veneers is mainly measured based on the following indicators: veneer thickness deviation (i.e. processing accuracy), veneer back crack degree, veneer back roughness and veneer transverse tensile strength. The first two of these indicators are the most important veneer...
