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.
LAW N. 1
Circulation increases with wood heating temperature.
LAW N. 2
Circulation increases with vacuum.
LAW N. 3
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
