The difference between traditional drying wood equipment and microwave drying wood
The difference between microwave drying equipment and other drying equipment: What are the advantages of microwave drying compared to traditional drying methods? Fast speed: the traditional drying method needs to be filled with a kiln and then dried (some materials may not be used in a large amount), and the drying cycle is long; microwave drying is ready to use, and how much to use, which is beneficial to capital turnover. How long does it take for the tunnel microwave drying equipment to feed from the feed to the discharge? Affected by two factors: 1, the water content of the incoming material, the higher the water content, the longer the drying time; 2, the thickness of the wood, the thicker the internal moisture of the wood is less likely to evaporate quickly to the surface, the time required is relatively Longer. In general, it takes about 20-30 minutes from feeding to discharging. Will wood be deformed and cracked during microwave drying? Improper operation can cause cracking and deformation. In addition, if there is a crack in the incoming material, the crack will become larger during the drying process. How can we stop this situation? We recommend that the incoming materials with different thicknesses and water contents be debugged, and record the transmission speed of the wood with different drying efficiency of the different specifications. The value of the inverter should be adjusted to the corresponding value when the device is turned on next time. So fast speed can really dry wood? There are two cases: 1. The density of wood is small, such as: poplar, the water is easy to come out, and it can be dried once. 2, the density is relatively large, such as: rosewood, rosewood, ebony, chicken wing wood, iron wood beans, Brazilian rosewood and other water is difficult to pull out from the inside, if forced drying may lead to wood deformation, cracking . Take the rosewood as an example. The high content of the redwood tree oil is too fast to pull the tree oil to the surface. In the process, the activity of the wood will be destroyed, and the moisture inside will not come out, and the surface moisture will not be immersed. 1cm thick mahogany can be dried once to meet the requirements, and 1cm or more depends on the dryness required by the manufacturer. If the dehydration requirement is not very high, it is also possible; if the wood is thick and the dehydration requirements are high, it is recommended to dry it several times. Can different sizes of wood be mixed and dried? Microwave heating is completely different from traditional heating methods. Microwave is to make the material to be heated become a heating element. The more the amount of sweat, the more dry it is. Therefore, wood with different specifications and different water content should not be dried. Can tunnel drying equipment be shorter? Based on years of experience and market feedback, we strongly recommend that the equipment be made as long as possible, because the wood drying temperature can not be too high, the temperature is high and the wood is easily carbonized, deformed or even cracked. The equipment is too short from the feeding to the discharge time is too short, the drying efficiency is greatly reduced, and the expected effect is not achieved; the equipment is made longer, the microwave field strength is small, and the wood is slowly dried at a low temperature in the microwave cavity to achieve the best. effect.

Dry evenly: the traditional drying is from the surface to the inside, there is a heat conduction process, and it is easy to occur in the outer coke. Usually, the internal moisture will penetrate outside after a period of time, and the product is not a seam or a shrinkage. Microwave drying removes moisture from the inside out, effectively solving the problem of drying during the traditional drying process. Microwave drying can penetrate the inside of the wood and kill the eggs, which can prevent cockroaches, mildew and prolong the shelf life.
