SWKD-4.0HFV VacuumWood Dryer
SWKD-4.0HFV Vacuummodel is small capacity high frequency vacuum kiln which is suitable for small sawmill, furniture manufacturer and guitar maker and other wood artist products
SWKD-4.0HFV Vacuum Wood Dry Kiln working principle
The principle is using the wood as a medium, capacitor is a group between two pieces of metal plate.Then give them voltage, the electric field produced between the two plates. The water molecules between electrodes will be polarized by the alternating magnetic field and move in very high speed rapidly.
The impact and friction (billion of times per second) among water molecules creates heating in very short time.
The conventional steam kiln or common vacuum kiln is use the heating transfer to dry the wood from surface to core.
High frequency power does not heat wood moisture but let wood moisture heated themselves.
It is kind of directly heating,This continuous effect let whole wood heated surface to core wholly and uniformly.
That is one of the reason why the high frequency vacuum machine is 10 times faster than conventional wood drying kiln.

Main Features of SWKD-4.0HFVhigh frequency vacuum wood dryer
Several areas of the drying process must be examined when comparing.The advantages of High Frequency drying are:
1) HF vacuum dryer offer a significant reduction in drying times. In many cases as little as 1/10th of the time that is required when drying in conventional kilns.
2) HF vacuum dryer have the ability to dry heavy stock (8/4, 10/4, 12/4) and large timber efficiently and without major defect.
3) Heat treatment temperatures in HF kilns can be reached in much less time than conventional heat treatment methods as a result of efficient “direct heating”.
4) Under the vacuum condition, wood is heated at lower temperature and withtout the oxygen, it will keep wood nature color
5) HF vacuum dryer do not require sticks between the lumber which eliminates sticker labour and stick stain.
6) HF vacuum dryer can be used as a method to re-dry material rejected from conventional kilns or to quickly reduce moisture content in lumber prior to de-humidification
7) HF vacuum dryer run solely on electricity thereby eliminating the need for large commercial boilers. This creates a greener footprint on the environment.
8) HF vacuum dryer can be installed quickly and moved easily when renovations or expansions are required
9) During the drying process under high frequency heating, eggs and worms can be kill.no need additional chimical.
Drying result
Some typical wood speices moisture content test after finish the dyring process by hf vacuum dryer kiln.
If you are suffering from cracking, bending, and can’t bear the long drying process. it’s time to use hf vacuum kiln
