High frequency vacuum dry kiln is also called radio frequency vacuum dry kiln.
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.
The hardwood from 30% moisture content to 8-10%MC only take 4-6 days and the fresh cut wood only take 10-12 days to get 8-10% moisture content. |
