What are the three basic functions of wood drying equipment
The basic principle of wood drying equipment is that the moisture in wood mainly includes natural moisture and absorbed moisture. The water present in the large capillary system composed of cell cavities is called natural water, and its amount directly affects the weight of wood without affecting its properties; The water present in the microcapillary system composed of cell walls is called adsorbed water. Its changes not only cause wood to shrink and expand, but also affect other physical and mechanical properties of wood.
The wood drying equipment needs to achieve forced drying of wood and has three basic functions: heating, humidity regulation, and ventilation. The heating function is self-evident: used for adjusting humidity (spraying steam or atomizing water). To ensure a high humidity environment required for certain stages of drying and prevent wood cracking, deformation, etc.: Ventilation equipment ensures that humid and hot air evenly passes through various parts of the wood pile, making the moisture content of the dried wood uniform.
