How to prevent wood cracking during drying process？In the process of wood drying, the end of wood is dried first because of the rapid evaporation of moisture. When the moisture content of the end is lower than the fiber saturation point, the end cells begin to contract. When the drying shrinkage st
Drying is not simply to control the moisture content of wood, but to eliminate the tensile stress of wood under the premise of ensuring that the wood fiber is not damaged, so as to make it more stable and ensure the product quality. High frequency vacuum wood dryer machine is getting more and more popular all over the world, it is also a good way to slove the end carcking problem. if you are interested in it welcome to talk with Carlos
What's the delivery time of your high frequency vacuum wood dryer kiln?After you place the order, we need 25 days to finish the production of high frequency vacuum wood dryer kiln. and then we will arrange the shippment. If you have plan to purchase the high frequency vacuum wood dryer kiln from us. pbecasue the different voltage from different country's client, we do not have stock. so please contact us earlier.
Fire is big problem for wood factory, if the kilns catching fire, my company will close down. Spark protection is one of our kiln's self protection program, if some wrong connection bring spark inside of the high frequency vacuum wood dryer kiln, the kiln will power off immediately. Another reason it won't catching fire is the vacuum, inside of the wood dryer kiln is a vacuum condition, even if it is sparked, it won't fire. Because no oxygen. So no worry about the fire, if sparked, the operator just need check the connection will be ok.
There are several main stream methods for wood drying, air drying, conventional steam dry kiln, vacuum kiln and high frequency heating vacuum kiln and etc. Because fast drying and high quality drying result, the high frequency heating vacuum is more and more popular in wood industry. so what's the difference between high frequency heating vacuum kiln and other vacuum kiln?The vacuum principle is same, both of them is to lower the boiling point of water and make the wood heated at low temperature. The main different is the heating principle. Other vacuum kiln is use heat plates. Each of pcs wood is sandwiched by heated plates (the plates filled with hot water or oil) The heated plates transfer heating from surface to the core of the wood. This way is no problem for thin lumber, if for the thick wood, it will be better to use high frequency heating vacuum kiln, the high frequency or radio frequency is kind of direct heating. The principle is using wood as medium, capacitor is a group between two pieces of metal plate, after give them voltage, the electric field produced. The water molecules between electrodes will be polarized by alternating magnetic field and move in very high speed rapidly.The impact and friction (billons of times per second) among water molecules created heating in very short time. So the conventional steam kiln or common vacuum kiln is use heating transfer to dry the wood from outside to inside of the wood. high frequency heating is let wood moisture heated themselves, this continuous effect let whole wood heated surface to core wholly and uniformly. That is also one of the reason why high frequency vacuum wood dryer is faster than other wood dry kilns
