As the main equipment for drying wood, the veneer dryer's drying speed will directly affect the quality and efficiency of drying veneers. Therefore, we must fully understand the factors that affect the drying speed in order to make it better. play a role.

One of the main factors that affects the drying speed of the veneer dryer is temperature. The increase in temperature can accelerate the evaporation of moisture on the surface of the wood, so the drying of the wood will also be accelerated. However, it should be noted that the temperature during drying must be properly controlled, otherwise excessive temperature will cause cracking, deformation, reduced mechanical strength, discoloration and other problems of the wood.

Humidity is also an important factor affecting the drying speed of the veneer dryer. When the air flow speed is the same as the temperature, the higher the relative humidity, the slower the evaporation rate of water on the surface of the wood will be, and thus the drying speed of the wood will also be slowed down; When the relative humidity is low, the diffusion and evaporation of water on the surface of the wood will accelerate, and the wood will dry faster. However, if the relative humidity is too low, it will cause problems such as cracking. Therefore, it is still necessary to use a veneer dryer for reasonable humidity control to ensure the stability of the humidity in the drying room.

In addition, the circulation speed of the air flow is also a factor that affects the drying speed of the wood dryer, because the high-speed air flow will destroy the saturated steam boundary layer on the surface of the wood, thereby changing the heat and mass transfer conditions between the medium and the wood, thereby speeding up the wood drying process. Drying speed.
