The role of steam generators in the wood drying process

The exquisite wooden handicrafts and wooden furniture we see in our daily life need to be dried before they can be better displayed in front of us. Especially in the production and processing of many wooden furniture, in addition to the quality of the wood, the drying process is also particularly important, because the wet wood is easily infected by fungi, causing mold, discoloration and decay, and is also susceptible to insect attack. If the wood that is not fully dried is made into wood products, the wood products will continue to dry out slowly during use and may shrink, deform or even crack. Defects such as loose tenons and cracks in the panels may also occur.

Electric steam generators are used to dry wood. The dried wood has good dimensional stability, corrosion resistance and environmental protection, which greatly improves the use range of its wood. This makes steam generators more and more popular. It has attracted the attention of furniture companies and wood processing industries.

After the large tree is cut down, it is cut into strips or slices and then dried. Undried wood is susceptible to mold infection, which can cause mold, discoloration, insect infestation, and eventually rot. For use only as firewood. Sometimes the plank beds we purchase sit up and squeak after a while, which is a sign that the planks were not dried thoroughly before being made into bed planks. If wood that has not been thoroughly dried is made into furniture products, the furniture products will continue to dry slowly during use, causing the wood to shrink, deform, and even crack, as well as defects such as loose mortises and cracks in puzzle pieces. Therefore, the wood must be dried using an electric steam generator before processing.
Wood drying steam generator meets processing temperature requirements
Reducing moisture content is the purpose of wood drying. As we all know, the temperatures required for each stage of preheating, heating, holding and cooling need to be adjusted at any time. Generally speaking, after the wood is stacked into the heat treatment equipment according to the conventional drying method, it needs to be preheated, and the temperature and time depend on the thickness of the wood. The heating process is divided into three stages, each stage has a different heating rate. During this period, an electric steam generator is used to inject steam intermittently to regulate the temperature and humidity in the equipment. Because the temperature is too fast, it may cause wood burning, warping, cracking and other problems. During the heat preservation and cooling process, steam is needed as a protection and cooling measure.
Electric steam generator prevents burning during wood processing and drying
During drying and heat treatment, the steam used serves as protective steam. The protective steam produced by these steam generators primarily prevents the wood from burning, thereby affecting the chemical changes that occur within the wood. It can be seen that the importance of steam in wood heat treatment is also the reason why wood processing plants use electric steam generators for drying wood.
