High Frequency Vacuum Drying Kiln Technology
The high frequency vacuum wood drying kiln adopts high frequency medium heating and vacuum dehydration technology.
High frequency is also called radio frequency, this technology is a kind of direct heating. The principle is using the wood as a medium, the wood acts as a capacitor. . When giving the two pieces of metal plate voltage, an electric field is created between them. Then water molecular in the wood and between electrodes will be polarized by the alternating magnetic field and move in very high speed rapidly. The impact and friction (billions of times per second) among water molecules creates heating in very short time.
Different from the conventional steam kilns or common vacuum kilns which are use hot air or heated plates to dry the wood from surface to core. High frequency power does not heat wood but makes moisture inside the wood heating themselves. It is a kind of directly heating, This continuous effect allows the wood heated from surface to core wholly and uniformly.
That is one of the reasons why the high frequency vacuum machine is 10 times faster than conventional wood drying kilns. The hardwood from 30% -40% moisture content to 8-10%MC only take 4 days and for the fresh cut wood it only takes 10-12 days to get 8-10% moisture content.
Our kiln also adopts vacuum dehydration technology. The stainless steel vacuum pump can drain out the air and the atmospheric pressure in the vacuum chamber can reach -0.093Mpa, which allows water to vaporize at a low temperature below 40℃, At the same time, vacuum can also suck the vapor out.
The machine water circulation system will condensate the vapors in the chamber, then drain them out.
Meanwhile Wood is drying under a vacuum wet and low temperature condition. It is nice to the wood and will ensure that the wood is no cracks and with nature color.
Main Features of SWKD-20.0HFV high frequency vacuum wood dryer
When labor costs and land costs rise, people begin to use machinery for more accurate and efficient production, which also affects the wood drying industry. Some forward-looking companies like Shuowei have begun to use the latest technologies like high-frequency Drying and vacuum drying
Shuowei’ HFV wood drying covers all the advantages of kiln drying, and at the same time, with the help of computer-aiding-design, it is a step closer to the auto control system. Its requirements for workers are far lower than the traditional kiln drying. The combination of different drying technologies greatly improves the efficiency of energy utilization and ensure the high quality of wood drying.
The drying circle will greatly shortened if you use SW series wood drying kilns, the drying time for the pine board will be only 4-6 days, While Drying fast means increasing output, inventory turnover and better cash-flow
With the help of vacuum chamber, the wood could be dried at a low temperature, which will do good to the quality, as it is known there will be about 13%-15% waste for normal drying, by this drying kiln it could be controlled to be 1%, thus to sell better price for the same batch.
