Timber drying equipment is mainly used in the timber industry products are: mahogany furniture, sour branches, sandalwood, old ship wood, river sunken wood, solid wood flooring, wooden handicrafts, solid wood doors, composite wood doors, etc., whether it is a hardwood or the density of the wood is relatively loose can be achieved fast drying. But the shortcomings of microwave wood drying is: for the drying of logs (fresh wood) is not very suitable, because the moisture content of the logs is relatively high, most of them are up to 50% of the water, such wood using microwave drying on the one hand, the cost of electricity is relatively high, a cubic meter of fresh wood drying needs to be more than 400 degrees of electricity, drying effect is also not very good, compared to, for example, said the deformation, cracking and so on. The type of wood, so that the microwave wood drying equipment is best used for secondary drying of wood and insecticides. On the other hand, the volume of drying is limited, each time the amount of drying is about 1~2 cubic meters, the maximum capacity is only 3~4 cubic meters.
There are three types of microwave lumber drying equipment: microwave lumber vacuum dryer, microwave lumber drying kiln, tunnel-type microwave lumber fast dryer. Above for you to explain what kind of wood to choose which kind of microwave equipment is more appropriate.
The microwave lumber vacuum dryer is for some high-density wood use, because it is in a vacuum state for uniform heating and drying, so the wood can reach the low temperature environment for drying. The main body of the equipment is made of 10mm thick steel plate welded, the equipment works first tank air through the vacuum pump, so that the internal environment of the air pressure to reach a negative pressure (-0.98Mpa) state, in this environment, microwave wood drying equipment for wood heating, drying in order to achieve the real low-temperature drying effect to ensure that the wood in the drying time does not crack, do not deform. Therefore, at present, microwave wood vacuum dryer is the most suitable wood low-temperature drying equipment for furniture industry manufacturers. A few years our production of microwave wood vacuum dryer in Guangzhou, Fujian, Jiangsu and Zhejiang has been a large area of use, and get the praise of the majority of users and promotion.
Microwave lumber drying kiln, compared with the vacuum drying equipment, its equipment cost is relatively low, and it also has a certain limit. It can only be low moisture wood for secondary drying; there is also a high density of hardwood drying is not quite feasible, of course, depending on the species of wood and the argument. Microwave wood drying equipment kiln is heated and dried under atmospheric pressure, so the drying temperature will be higher than the vacuum dryer, so this is also it can not be applied to high-density hardwood drying reasons. It is mainly applied to some medium and high density wood, plate for secondary drying.
Of course, the tunnel microwave wood fast dryer, it is mainly applied to thin a little bit of plate for the second drying and insecticidal, at present is mainly used in solid wood flooring, composite flooring and wood doors and other industries, tunnel microwave wood drying equipment drying speed is relatively fast, for example: 20% of the wood flooring will be dried to 8%, through the equipment conveyor system, from the feed conveyor to the discharge of the material in only 5 ~ 6 minutes. 6 minutes. Most of the application industry enterprises mainly want to use this equipment on the product of insecticidal and trace drying, especially wood crafts industry, wood flooring, wood hanger industry, tunnel microwave wood drying equipment is one of the essential equipment for the export of their products.
