During normal operation, the fuel is fully combusted in the combustion chamber to generate heat energy and is fully absorbed by the drying medium in the thermal energy drying system to produce a temperature of about 180 degrees Celsius. Under the action of the circulating fan, the high-temperature airflow passes through the control system and the conveying system. The high-temperature hot air is transported to the drying room to dry the wood.
At the same time, the steam-generating device on the wood dryer can produce a large amount of atmospheric steam. According to the requirements of the drying process, the steam can be sent into the drying chamber at the right time to spray the wood and adjust the humidity. The humidity control system is an independent steam system. Equipped with safety devices.
Saturated wet steam can make the surface temperature and internal humidity of the wood become consistent in a short time, so as to achieve the purpose of drying both the inside and outside of the wood. For solid, heavy, hard, and thick wood, the intermittent heating and drying process can be used. The defects such as internal cracking, end cracking, and deformation of wood during the drying process are solved, and the yield of high-quality wood is greatly improved.
The wood drying equipment is equipped with a heat recovery system, which greatly reduces the drying cost and shortens the drying cycle. When the moisture content of the wood drops below 15%, after 6-8 hours of high-temperature dry steaming, all the worms and eggs parasitic in the wood can be eliminated, which solves the adverse effects caused by the worms and improves the company. Economic benefits.
