The Vacuum Drying Principle
Two phenomena can be observed while drying wood
A - Circulation of the water from the core to the surface of the wood.
B - Evaporation of the water at the surface of the wood.
Since circulation A is a much slower and more difficult phenomenon than evaporation B, physical laws must be implemented to increase the circulation in order to reduce drying time.
Circulation increases with wood heating temperature.
Circulation increases with vacuum.
The greater the vacuum, the lower the water boiling temperature.
To reduce drying times and to guarantee perfect dried wood quality, the vacuum drying method utilizes all the abovementioned physical
