High Frequency Vacuum Dryer(3CBM)

High Frequency Wood Vacuum Dryer (3 CBM) 1. Advantages 1) High frequency heating, more equal, dry faster; 17times faster than wood dust burnt dryer. The drying cycle are mainly 20-30hours.(It differences with the different wood type and size) 2) Vacuum condition, dry faster in lowr temperatureto eliminate the problem of split. It is more suitable for A.Large square wood material B. Hard board leaved tree material C. Rare wood as well as other rare wood material. 2. Features 1). In vacuum condition, drying at lower temperature.(60°C or lower, adjustable) 2). High Frequency heating. almost 17 times faster than conventional dryer. 20-30 hours per cycle. 3). Cylinder pressure to prevent bending. No cracking and no bending. 4). It is suitable for all kinds of wood,especially for hard wood, rare wood. It can save the time and cost. 5). Worm killing and no color changing. 6). No polution. 3. Thoery HF and Vacuum condition: As HF heats from inside, so the core of wood will dry first, and then gradually to the outside, then the vacuum pump extract the moisture out from inside thus make the surface of wood is always wet, for some hard wood if the surface is dried quickly, there will be spark on the surface and leave permanent defect on the wood, but HF vacuum condition will totally eliminate the problem. 4. Temperature control: There is temperature sensor which guard on the temperature, user can set different max and min temperature according to different wood, then if the temperature reaches the max limit, the heating stop, but if it falls to the min, the heating will start again. For some hard wood that very sensitive on the temperature, this is a big advantage.
