high freuqency vacuum wood drying kiln made in China

high freuqency vacuum wood drying kiln made in China     DXHF has engaged in HF field for more than 20 years and is the first brand in China. Cooperation and exchange technology with international HF expert can supply yearly the top quality equipment and quote reasonably. DXHF vacuum dryer has two parts, one part is the high frequency generator and the other part is the vacuum dryer oven.   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     Advantages     Why we choose HIGH FREQUENCY VACUUM?
