HF vacuum wood dryer machine for All kinds of wood
1: Uniform heating
2: Speedy drying without cracking
3. Square shape volume saving
A.--High Frequency Vacuum Wood Machine
High frequency vacuum timber dryer adopts high frequency drying, inside and outside of wood timber is heated at
same time, uniform heating, high speed drying, short time and good quality, which may keep the timber nature color,
meanwhile, the timber is aerated under the vacuum environment, non-cracking, especially applied for the thick and
hard precious wood, wet wood.
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
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.
High frequency can kill the worm and bacteria. It does not need special chemical treatment.
B.--High Frequency Generator Heating Principle
HF generator is the core of dielectric heating equipment. It applies three phase alternating current to form frequency
oscillation electric field .Under this high frequency electric field, the molecules like water .glue or PVC will be
polarized and form two poles.
The electric field will change pole rapidly meanwhile all the molecules will also move in very high speed. The friction and impact among molecules can make material get heated in short time. Then the water will be vaporized, glue
becomes solid and PVC gets softened rapidly.
C.--The Vacuum Dryer Oven Drying Principle
High vacuum timber dryer adopts high frequency drying, inside and outside of wood timber is heated at same time, uniform heating, high speed drying, short time and good quality, which can keep the timber nature color, meanwhile, the timber is aerated under the vacuum environment, non-cracking, especially applied for the thick and hard precious wood, wet wood.
Temperature and accuracy testingadopts optical fiber testing, it is effectively avoid High frequency interfering measuring instrument.
It adopts weight method and Kiln moisture meter, which cantest moisture rate online
The container is handled by professional chemical anticorrosion, no rustiness, so that save the container maintenance and avoid pollute the timber
