High Frequency Vacuum Lumber Drying Equipment
High Frequency Vacuum Wood Machine is the result of design combining High frequency medium heating technology and Vacuum cryogenic dehydration technology. The working principle of HF medium heating: in the high frequency electrical filed, friction of medium molecule generates heat. Keeping the wood in the frequency electrical filed, thus the inside & outside of wood will be rapidly heating. Meanwhile, vaporizing temperature of water will be decreased under vacuum conditions. DXHF 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.
HF Vacuum Lumber Drying Equipment
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. 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.
HF Vacuum Timber Drying Equipment
High Frequency Vacuum Wood Dryer adopts high frequency drying. It consists of three parts： Vacuum Drying Kilns - High Frequency Generator- Cooling Tower. Our vacuum wood drying kiln is a square box. It is also the only factory in China that produces square boxes, and has won the national patent. It can make the wood at the same time heating even, drying speed, short time, good quality, not only can keep the natural color of wood, but also can be inflated in the vacuum environment, not cracking, especially suitable for thick and precious wood, wet wood.
HF Vacuum Wood Drying Equipment
Fast speed and high efficiency. High frequency heating is 3-5 times faster than hot steam.So it can save the power and improve the efficiency. Uniform heating. High frequency heating is dielectric heating.it forms electric filed with positive and negative pole.HF power can penetrate material deeply.The water or glue molecules in the material will get heated themselves by friction among molecules.In this way,they get heated from the core material,much more uniformly. Good applicability. High frequency heating can heating can heat kinds of thickness material.,such as 2-3 mm veneer surface lamination.1000mm thick engineered wood gluing. And different frequency can meet different material requirement . Strong controllability. High frequency heating is easy control and suitable for automatic production. Environment friendly. High frequency heating does not need boiler,there is no dust,no fog,no pollution.
Vacuum Drying Equipment
The advantages of high frequency vacuum wood drying kiln lie in the following points： 1.Quick heating： It does not require heat conduction, inside and outside of wood timber is heated at same time. 2.Fast dehydration：During the heating process, there is staged temperature difference between inside and outside of wood timber, this will speed up the water movement from inside wood to outside wood (the principle is to the convencontrary tional heating). 3.Good quality of final wood ：There will be no cracking, bending and color change by taking control of heating speed, relative vacuum degree & condensing rate. 4.Strong adaptability： High frequency vacuum drying can realize not only cold drying but hot drying, help to eliminate stress, solidify resin. This applies to dry all kinds of wood. 5.High usage：Square designed drying box supplies more space utilization.It is suitable for different shaped wood. 6.Cost saving: Fast temperature raise and higher space utilization takes lower cost than traditional ways. 7.Full-automatic: UA Unattended Automatic drying process, very easy to handle. 8.Eco-friendly: This machine does not pollute the environment.
