HF Vacuum Dryer (3CBM)

1.HF Vacuum Dryer 2.All kinds of wood 3.Faster and more uniform 4.No crack no bend 5.Worm killing

High Frequency Wood Vacuum Dryer (3 CBM)

1. Features

1). In vacuum condition(-0.09MPa), 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.(depends on wood type, size and moisture)

3). Cylinder pressure and press 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). Does not need boiler No polution.

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.

3. 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.
