1) Most of the veneer dryer machines currently in use use 0.4-1.0MPa saturated steam as the heat source. The radiator is heated first, and then the air is heated to 140-180°C through the radiator, and the hot air transfers the heat to the veneer. The combustion gas of coal gas, petroleum and light diesel fuel is also used to heat the air. 2) The wood veneer dryer machine is equipped with a hot air...

Plywood hot press is carried out in a multi-layer hot press machine. When using a multi-layer press with a plate unloader, the working procedure is: first load the pre-compressed slabs one by one into the loading rack, and then push a car of slabs into the hot press through the loading machine. The press is closed, the pressure is increased, and kept under a certain pressure for a per...

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 ...
