HF vacuum dryer in Canada
Cheif Manager Mr.Leo and Technician Mr.Xie have installed the high frequency vacuum wood dryer in Canada on the end of 2015
This is one set full auto type vacuum kiln. You can red the moisture content from the screen.
High frequency is also called radio frequency, it is a kind of direct heating.
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.
As our coustomer Mr.Paul saying, the 2" thickness black walnut,ash and maple dry to 6-8%MC only take 10 days.
Our kiln also adopts vacuum dehydration technology.
The stainless steel vacuum pump can make the vacuum oven reach -0.093Mpa condition.
The vacuum condition is to let let water vaporized in low temperature below 55 ℃,At the same time, vacuum can also suck the wood moisture out.
The machine cooling system will separate the hot air and hot water out, then cool them and release them out.
Wood is drying under a vacuum and wet condition at low temperature. That will ensure wood is no cracks and keep the wood nature color.
Thank you guys to hold the celebrate party.
This is the vote of confidence for our high frequency vauum kiln and the trust for our company and team.
