Experts on microwave drying equipment talk about how to choose drying equipment.

Microwave wood drying equipment is a new type of equipment widely used in recent two or three years, which is used to quickly dry wood and kill insects. Its drying advantages are: faster drying speed. Ordinary drying equipment needs to dry wood for one month, and microwave wood drying equipment only needs about 20 hours. In addition, microwave drying can achieve both insecticidal and mildew-proof effects, which is a significant advantage for product enterprises.

Wood drying equipment is mainly used for wood products: mahogany furniture, rosewood, sandalwood, old ship wood, river sinking wood, solid wood flooring, wooden handicrafts, solid wood doors, composite wood doors and so on. Hardwood and relatively loose wood can be dried quickly. However, the disadvantage of microwave wood drying is that it is not suitable for drying logs (fresh wood) because the moisture content of logs is relatively high, most of which reach 50%. On the one hand, the cost of microwave drying this kind of wood is relatively high, and the drying effect is not very good, such as deformation, cracking, etc., but it also depends on the type of wood, so to speak. On the other hand, the drying volume is limited, with the drying volume of about 1~2 cubic meters each time, and the maximum capacity is only 3~4 cubic meters.

There are three kinds of microwave wood drying equipment: microwave wood vacuum dryer, microwave wood drying kiln and tunnel microwave wood rapid dryer. The above will explain in detail what kind of wood and microwave equipment are suitable for you.

Microwave wood vacuum dryer is used for some high-density wood. Because it is uniformly heated and dried in vacuum, wood can be dried at low temperature. The main body of the equipment is welded by a steel plate with a thickness of10 mm. When the equipment works, the air in the tank is pumped out by a vacuum pump to make the internal ambient air pressure reach negative pressure (-0.98Mpa). In this environment, microwave wood drying equipment can heat and dry wood to achieve a real low-temperature drying effect and ensure that wood does not crack and deform during drying. Therefore, at present, microwave wood vacuum dryer is the most suitable low-temperature wood drying equipment for furniture manufacturers. In recent years, the microwave wood vacuum dryer produced by our company has been widely used in Guangzhou, Fujian, Jiangsu, Zhejiang and other places, and has been well received and popularized by the majority of users.

Compared with vacuum drying equipment, the equipment cost of microwave wood drying kiln is lower, but it also has some limitations. It can only dry wood with low water content for the second time; In addition, high-density hardwood is not feasible, of course, it depends on the variety of wood. Microwave wood drying equipment kiln is heated and dried under normal pressure, so the drying temperature will be higher than that of vacuum dryer, which is why it can not be used for drying high-density hardwood. It is mainly suitable for the secondary drying of some medium and high density wood and plates.

Of course, the tunnel microwave wood fast dryer is mainly suitable for the secondary drying and insecticidal of thin plates. At present, it is mainly used in solid wood flooring, composite flooring, wooden doors and other industries. The drying speed of tunnel microwave wood drying equipment is relatively fast, for example, 20% of wood floors need to be dried to 8%, and it only takes 5~6 minutes from feeding to discharging through the equipment conveying system. Most enterprises in the application industry mainly want to use this equipment to kill insects and dry products in small batches, especially in the wooden handicraft industry, wooden floor and wooden hanger industry. Tunnel microwave wood drying equipment is one of the necessary equipment for the export of its products.
