With New 2007 friends!
I build vacuum drying chambers without fans, dampeners.
When dried a pine, a cedar, an alder, a cherry, the Siberian larch thickness 25 - 35 mm were drawn with a conclusion what to dry movement of air without vacuum is possible with natural.
I began to do(make) the control drying. The result has turned out good.
The wood dries up to humidity of 6 %.
Disorder of humidity on a stack of 1 %.
Disorder of humidity on thickness a board of 0.2 %.
Disorder of humidity on length a board of 0.3 %.
Internal pressure(voltage), cracks are not present.
Cost of construction drying the chamber small.
From the small container, volume of loading of 8 m3, I have constructed the drying chamber volume of loading of 18 m3.
Result of drying good.
On drying of 1 m3 a pine thickness of 52 mm, an expense 150 kw.
Term of drying from humidity of 65 % up to humidity of 6 % - 8 days.
I have made the diagram of drying universal.
1 day - 45 degrees C, 7 days - 75 degrees C.
Pairs leaves through apertures in an atmosphere, open in the different period of drying from falling humidity of a tree.
I measure temperature in the chamber, temperature of water in system of heating of 95 degrees C. 4 gauges I measure humidity of a tree a needle.
In a stack it is possible to put different breed of a tree and different thickness. 25 mm - 35 mm dry equally well!
