Product Details

HF vacuum drying equipment for wood/timber/lumber

Product Description

One of china HF vacuum dryer manufacturers: Henan dingli drying equipment. High frequency vacuum wood drying machine is our company as the principle of high frequency heating and vacuum suction, with reference to the Japanese technology development and production of wood drying equipment

The wood/lumber/timber drying process with HF vacuum drying equipment

1. It is new drying method. (Dielectric heating)
Steam and normal vacuum dryer(hot plate) is conductive heating.
They dry the wood little by little from outside to inside.
High frequency is dielectric heating. HF wave can penetrate the thick wood
And dry it uniformly. Even the core of wood temperature is heater than surface.
Vacuum condition: It is minus pressure, safe.
The wood moisture can vaporized in low temperature.
Then vapor will be pump out automatically.
So HF vacuum dryer is faster, more uniform, no bending and no crack caused by non-uniform.
2. No need boiler; No need hot plate (no hot water)
The power supply of HF vacuum dryer is electricity.
It does not need boiler, save the human resource and protect the Environment.
3. Worm killing.
High frequency can kill the worm and bacteria.
It does not need special chemical treatment.
