Vacuum Drying machine
Vacuum drying machine,dryerr machine,drying machinery
Block wood, veneer, and panel
Fast drying 20 to 30 hours per cycle
No cracking, no bending
Worm killing
Advantages of Vacuum drying machine,dryerr machine,drying machinery:
High frequency heating, more equal, and dry faster
17 times faster than wood dust burnt drying machine
The drying cycle are mainly 20 to 30 hours (it differences with the different wood type and size)
Vacuum condition, dry faster in lower temperature to eliminate the problem of split
It is more suitable for Vacuum drying machine,dryerr machine,drying machinery:
Large square wood material
Hard board leaved tree material
Rare wood as well as other rare wood material
Features of Vacuum drying machine,dryerr machine,drying machinery:
In vacuum condition, drying at lower temperature (60°C or lower, adjustable)
High Frequency heating, almost 17 times faster than conventional drying machine
20 to 30 hours per cycle
Cylinder pressure to prevent bending
No cracking and no bending
It is suitable for all kinds of wood, especially for hard wood, and rare wood
It can save the time and cost
Worm killing and no color changing
No pollution
Theory
HF and vacuum condition of Vacuum drying machine,dryerr machine,drying machinery:
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
Temperature control of Vacuum drying machine,dryerr machine,drying machinery:
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
