Bamboo and wood products need to be dried and kill insects to prevent wet materials from cracking, shrinking and being eaten by insects in the use environment. Traditional drying is nothing more than hot air kiln (furnace) drying for a long time. Bamboo and wood have longitudinal fiber structure, in the traditional heating, bamboo and wood wet material transverse thermal conductivity is particularly poor, to make its center to meet the drying requirements not only for a long time, but also because of the fiber structure and texture of the different, uneven heat in all directions, in the drying process of material cracking, distortion, scrap rate is high. Secondly, when the moisture content of the material is reduced to less than 10% by traditional heating, it is very difficult to further dry, and the drying method needs to be updated. Using microwave heating characteristics, bamboo and wood products can be dried by microwave to overcome the disadvantages of traditional heating and drying. In addition, at the same time of microwave drying, microwave also has a strong killing effect on the moth and egg in bamboo and wood products.
Therefore, the combination of microwave drying and insecticide is a very ideal method.
1.Fast drying speed. If the moisture content of wood is reduced from 35%-40% to 20%, the drying time is about 10-15 minutes, which is 20-30 times that of steam and conventional drying process.
2.Good wood drying quality.The traditional drying method will appear deformation, cracking, mildew, deterioration and other phenomena, seriously affect the quality of wood, resulting in a large number of scrap. Using microwave drying wood, the utilization rate of wood can be increased by about 5%, so a lot of wood can be saved.
3.Microwave wood dryer also can kill pests.During microwave drying wood process, can kill all the harmful moth eggs and larvae inside the parasitic wood ,when the treatment temperature of 70-80 degrees only 2-3 minutes, so it's applied to more and more factories.
4.Save energy saving and high efficiency.Microwave power directly act on the material, so there is no additional heat loss, the air in the furnace and the corresponding container will not heat, so the thermal efficiency is very high, the production environment is also significantly improved, compared with far infrared heating can save 30% of electricity.
5.Easy to control, advanced technology.Compared with the conventional way, microwave wood drying insecticide equipment is ready to use, no thermal inertia, flexible and convenient operation. Microwave power and transmission speed are all adjustable, which is a safe and reliable high technology.
6. Save floor space and improve working conditions. The equipment is small in size, and weak thermal radiation, so will not form the high temperature working environment. For various kinds of wood with different properties, it is necessary to first take the appropriate microwave heating speed to achieve the best process conditions, and obtain the best benefits.
Industrial microwave wood drying insecticide equipment have different models with different capacity . And it can be CUSTOMIZED according to wood charactertics and your requirements .
