In order to ensure the quality and prolong the service life of the wood and the wooden products, proper measures must be taken to reduce the moisture content, namely the water content, in the wood to a certain degree. To reduce the moisture content of the wood, the temperature of the wood is increased to evaporate and move the moisture in the wood outward, so that the moisture rapidly leaves the wood in the air with a certain flow speed, thereby achieving the purpose of drying. In order to ensure the quality of the wood to be dried, it is also necessary to control the humidity of the drying medium, such as the moist air commonly used at present, in order to obtain a rapid and high-quality drying of the wood, a process called wood drying. The drying of the wood is an important link for guaranteeing and improving the quality of the wood, reducing the loss of the wood, and the like and improving the utilization rate of the wood. Meanwhile, wood drying is also the most energy-consuming process in the production process of wood products, and accounts for about 60 to 70 percent of the total energy consumption of enterprises in China.
