The effect of wood drying equipment

With the development of social economy, the progress of human civilization and improvement of residents’ living standards, the quality and quantity of wood and its products put forward higher requirements, for wood processing technology, including control technology of the crowd is higher and higher demands are proposed.Defects such as cracking, bending deformation, mildew, seriously affecting the quality of wood products, so the wood before made all kinds of wood products for dry processing (control).Wood drying equipment configuration dehumidifier using dissipation moisture from the wood, use artificial method to force wood moisture evaporation, dissipation make the moisture content of timber fell and the level of the local equilibrium moisture content, avoid wood mildew or in the process of storage, transportation and use of hyphal erosion and wood splitting, deformation.The wood drying equipment is the device can effectively remove the moisture from the wood.
Wood in certain circumstances, after long enough, its moisture content will tend to be a balance value, known as the environmental balance moisture content of EMC.When equilibrium moisture content of lumber moisture content is higher than that of environment, the wood will platoon is wet contraction, vice of hygroscopic and expansion of will.Guangzhou region, for example, the balance of the annual average moisture content of 15.1%, in the Beijing area is 11.4%.Dry to 11% of the wood used in Beijing is appropriate, can be used in guangzhou will be hygroscopic expansion, deformation.So, wood drying, not as dry as possible.Different regions, different USES, demand for lumber moisture content is also different.
