 Combination woodworking machines /wood timber lumber dryer 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.   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. Package: Standard export packing, plastic and foam, fixed by wood pallet, shipped in container by sea Why we choose HIGH FREQUENCY VACUUM?

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. The 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. Automatic type function Adopts optical fiber testing temperature, accuracy, it is effectively avoid High frequency interfering measuring instrument. It adopts weight method and Kiln moisture meter, which can test moisture rate online The container is handled by professional chemical anticorrosion, no rustiness, so that save the container maintenance and avoid pollute the timber Save labor, automatic feeding and discharging. Built-in cooling system, lower the drying cost           Contact person:Joanna Xie Tel:+86-0311-89836929        Skype:joanna.xie01              ICQ:668674621
