One of the main factors that affect the drying speed of wood drying equipment is temperature. An increase in temperature can speed up the evaporation of moisture on the surface of the wood, and the faster the wood will dry. But it is worth noting that if the temperature is too high, it will cause deformation and cracking of the wood, reduce the mechanical strength, discoloration, etc., which should be properly controlled.

Secondly, humidity is an important factor that affects the drying speed of wood dryers. When the air velocity is the same as the temperature, the higher the relative humidity, the slower the evaporation of water on the surface of the wood, and the slower the drying speed; while the relative humidity is low, the moisture will diffuse, and the evaporation will speed up. The faster the speed. However, if the relative humidity is too low, it will cause cracking and other problems or even aggravate it. Therefore, it is still necessary to use a wood dryer for reasonable control to ensure the stability of the humidity in the wood drying room (explanation: stable and stable; no change).

The air circulation (continue) speed is also one of the factors that affect the drying speed of the wood dryer. Because the high-speed airflow will destroy the saturated steam boundary layer on the surface of the wood, thereby improving the heat and mass transfer conditions between the medium (the decisive substance) and the wood, and speeding up the drying speed.
