Descrption & applicable scope of drying kiln
A: High frequency vacuum drying kiln equipment is a relatively small and fast drying equipment
B:Applicable to thick hardwood or wood drying, solves the hardwood or large section of wood drying after deformation and cracking problems, because of its small volume and short cycle drying characteristics, especially suitable for solid wood furniture factory or wood processing manufacturers Wood drying or back late the water drying.

Working principle diagram of drying kiln
Using high frequency electric field is used as a heating source, even electric field radiation in the wood, and penetrates the wood directly on the water for heating, and the vacuum water absorption to accelerate water discharge.
The wood/lumber/timber drying process with HF vacuum dryer
high frequency drying kiln characteristics and advantages:
1: Short drying cycle--- HF kiln dryer greatly reduced drying time It does not require heat conduction, both inside and outside of wood timber is heated at same time;
During the heating process, there is staged temperature difference between inside and outside of wood timber, The vapor pressure difference caused by
this surface and the interior temperature difference makes the interior
moisture to move towards the surface. For this reason, the drying time is
much more shorter than traditional ways.
2: Good drying effect--- the wood is drying under vacuum condition, this will
decrease the drying temperature.
Wood drying at low temperature highly humid environment enable complete
free from cracks & distortions as well as retain its hue & luster.
Under constant evenly heating there is not any cracking or bendind appeared.
The moisture content of wood will be maintain a certain percent steadily after drying by hf kiln.
3: Easy Operation--- HF kiln dryer is fully automatic, you just push the cart loaded with wood into the tank, close the tank, and press the start button.
Operation is automatically performed in accordance to the preset program
4: Energy Saving--- The input power is much lower than other drying machine
5: Cost-Effective--- Low input and high out put.
Packing & shipment
1.Plastic and foam packing, fixed by wood pallet, it is packed in 40 feet container.
2.by sea transport
