Dehumidifier for wood drying

Wood contains a certain amount of water. The amount of moisture in wood varies with tree species, tree age and cutting season. In order to ensure the quality of wood and wood products and prolong the service life, it is necessary to take appropriate measures to reduce the moisture content of wood to a certain extent. In order to reduce the moisture content of wood, it is necessary to increase the temperature of wood to make the moisture in wood evaporate and move outward. In the air with a certain flow speed, the moisture can leave the wood quickly to achieve the purpose of drying.

In order to ensure the quality of the wood to be dried, the humidity of the drying medium (such as the wet air commonly used at present) must be controlled to obtain the effect of fast and high quality drying of wood. This process is called wood drying. Because the above method is the use of convective heat transfer, from the outside of the wood drying method, so, also known as convective drying. Generally speaking, wood drying is a process in which water is discharged from wood by evaporation or vaporization.

Wood drying is the key link of furniture production and decoration material processing, and it consumes a lot of energy. At present, some wood drying kilns in China are mostly Kang type flue gas drying kilns, and some small and medium-sized steam drying kilns are purchased. The common characteristics of these wood drying kilns are low thermal efficiency and high energy consumption. In addition, due to the lack of dust removal equipment or poor dust removal equipment, the dust content in the exhaust gas seriously exceeds the standard. The technology of using dehumidifier for wood drying has been relatively mature, its energy saving rate is about 80%, and industrial dehumidifier is becoming more and more popular.
