Vacuum kiln kiln body is cylindrical metal structure, compressive strength and good sealing. The dry principle is the use of vacuum degree within the tank, the lower the boiling point of water, speed up the water movement in wood, thereby improve the drying speed, shorten the drying time. So choosing vacuum drying, the drying temperature is low, can reduce or avoid wood drying such as inside crack, shrinkage defects. Vacuum drying method is suitable for dry hard broadleaf wood plate, its permeability good broadleaf timber has good drying effect.

High frequency generator

High frequency high cycle, also known as Europe and the United States called radio frequency (rf), is a kind of high frequency waves, under the effect of this kind of high frequency electric field, the molecules of the dielectric (for example: adhesive molecules, water molecules, PVC, rubber, etc.) by changing electric field polarization repeatedly, the positive and negative vibration molecular constant friction between the two electrodes, generate heat, fast curing, hot glue to make PVC products melt after pressing forming an organic whole, timber fast discharge after evaporation of the water molecules, such as glass fiber reinforced plastic rapid prototyping, so as to achieve quick heating, high efficiency, and selective heating effect. Is widely used for international is a new type of electromagnetic field processing technology.  

So high frequency vacuum wood drying equipment is the perfect combination of high frequency heating and vacuum dewatering.  

High frequency vacuum wood drying

A rapid increase in temperature, using high frequency heating solved the wood, fast drying speed.

Second, the wood inside and outside the heating at the same time, uniform heating, good quality and can keep the natural wood color.

Three, adopts vacuum suction decreased temperature make wood low temperature evaporation of wood drying process, not easy craze improve the dehydration rate of lumber.

Four, efficient, environmental protection don't pollute the environment.

Five, the high frequency wave that kill the hidden inside the plate insects and bacteria in shorten the drying period and further to ensure the quality of wood drying.

Especially suitable for thick, hard, big section of the wood (conventional drying methods for a long time) rare wood, such as rosewood, chicken wing wood drying, chrysanthemum pear, rosewood, etc. At the same time also use small batch, secondary drying after the urgent get damp wood.
