High frequency vacuum wood dryer machine is advanced wood drying equipment, which only needs electricity without boiler, environment friendly and easy to handle with. Comparing with conventional kiln dryer,high frequency vacuum wood dryer machine capacity is small and flexible, less factory space needed; efficiency is much higher (more than 10 times faster than kiln dryer). After seasoning, timber is kept straight and in high quality without cracking. Out-turn percentage of timber increased. HF vacuum wood dryer machine is the best choice for small and medium furniture manufacturers. High frequency is called radio frequency. It's heating principle is same with microwave, but wavelength different. High frequency generator generates electromagnetic fields between two electrodes through three phase alternating current. In this field, water molecules are polarized - rotated - heated by friction. High frequency heating is not like conductive heating, which heat material step by step, but make the wood heated themselves by friction. More than 50cm thick wood can dried by our high frequency vacuum wood dryer machine with uniform moisture contenct. High Frequecnyv vacuum wood dryer machine have some advantages in wood drying field.
1.Stable drying without defects
The wood is drying under vacuum condition,it is Low boiling point of water，it can be vaporized at 50℃. Low temperature drying solves the problems of wood cracking, deformation and discoloration, especially for precious timber sensitive to temperature.
2. Fast drying
High Frequecny medium heating make the wood heated very fast, Temperature Gradient of Internal High and External Low and vacuum pressure make water dischaged out very qiuckly. The 8cm thick Africa rosewood from 40-50% moisture content only take 7 days to reach 8-10% moisture content.
3. High quality drying result
High frequency vacuum wood dryer machine equipped with hydralic pressure system on top, the hydralic pressure system supply more than 4 tons pressre on the wood stacking to prevent wood deformaing and bending. We use stainless steel 304 to make the pressure plate.
4. Easy operation
PLC control system and Pneumatic system make it is easy to opetat.Automatic drying make it no need staff on duty during the drying process.
5. High quality high frequency vacuum wood dryer machine
Our high frequency vacuum wood dryer machine made with stainless steel to avoid corrison and rust. Stainless Steel Pressure Plate High Frequeny vacuum wood dryer machine is a great significance for precious hardwood drying. With the wide application and popularization of high frequency vacuum wood drying technology, great changes will be made in the wood drying industry and the economic and social benefits of enterprises will be effectively improved.
