Wood dryer refers to the process of dissipating moisture from wood, that is, using artificial methods to force the moisture in wood to evaporate and dissipate, so that the moisture content of wood drops to a level equivalent to the local equilibrium moisture content, to prevent wood from mildewing or being eroded by insects and fungi during storage, transportation and use, and wood splitting and deformation. Wood dryer is a device that can effectively remove moisture from wood.

When the wood dryer is operating normally, the fuel is fully burned in the combustion chamber to generate heat energy, which is fully absorbed by the drying medium in the thermal energy drying system, generating a temperature of about 170 degrees Celsius. Under the action of the circulating fan, the high-temperature airflow passes through the control system and the conveying system to transport the high-temperature hot air into the wood drying chamber to dry the wood; at the same time, the steam generator on the equipment can generate a large amount of normal pressure steam, which can be sent into the drying chamber in time according to the requirements of the drying process to spray steam and adjust the humidity of the wood. The humidity adjustment system is an independent steam system and is equipped with safety devices.

1. High moisture content: The function of the wood dryer is to evaporate the moisture in the wood through high temperature and dry environment, so the wood suitable for the wood dryer should have a high moisture content.

2. Moderate density: The higher the density of the wood, the more difficult it is to dry. Therefore, the wood suitable for the dryer should have a moderate density and should not be too dense or too loose.

3. Stable properties after drying: After drying, the properties of the wood may change, such as bending, cracking, etc. Therefore, the wood suitable for the wood dryer should have stable properties and is not easy to deform or crack after drying.
