During the LVL production process, the wood loss of each main process is roughly as follows: 1. Sawing loss (truncation, sawdust): generally 2%-3% 2. Rotary cutting loss (wood core, broken veneer): The proportion of wood core and broken veneer is related to the material and log diameter. LVL uses low-grade timber and small-diameter timber, but because veneer lengthening and spindleless veneer peel...

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...

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 ...

Laminated veneer lumber is a structural material made by processing wood into thicker veneers, drying, sizing, forming blanks along the grain, and laminating and gluing. Because it is basically formed along the grain, it is also called parallel plywood. Because it is similar to the performance of glued wood, it is also called veneer glued wood. Its manufacture is very similar to plywo...

The meaning of veneer dryer The moisture content of the veneer after rotary cutting is very high. If the veneer is directly sizing without drying treatment, and then the billet is hot-pressed, when the veneer is sizing, due to too much water, it is easy to cause glue bleeding, which will make the veneer glued together. Lack of glue on the surface; b...

First stage of plywood hot press This stage is the auxiliary time. In order to improve the productivity and product quality of the hot press, it is required that this stage should be carried out at the fastest speed and the time should be as short as possible. After the slab is loaded into the press, it is not subjected to external pressure. The glue layer near the hot pressing plate heats up very...
