The machine, operating at low temperatures, allows the timber to lose it`s water content without subjecting it to thermal changes which can cause cracking and warping.
The evaporated water which remains in suspension in the container keeps the drying material surface continuously humidified, avoiding in this way the formation of small cracks which, in other drying systems is quite frequent.
The humidity level which is necessary between environment and material is constantly maintained by a condenser which precipitates the steam in suspension. The conditioning of the drying chamber is kept constant and programmed in advance using probes connected to the heating and condensing circuits and to the timber.
This conditioning of the environment sets the transmigration process of the water through the cellular walls of the timber in motion. Passing from their inside walls towards the surface, from which the water is continuously evaporated until the desired drying conditions are reached. The condensate which deposits at the bottom of the dry kiln is periodically expelled in order to maintain the environmental conditions constant.
In this way the following advantages are had:
Quickness of drying:
Owing to process without air at low temperature which enables hourly deceases in humidity never before reached by any other systems.
Perfect Results:
Due to no cracks and no warping, no colours changes, no internal tension, and unchanged strength of the dried material.
Possibility of Drying:
Very thick material and with a very high humidity level, such as planks and wood of all kinds, semi finished items.
Low Operating Costs:
Thanks to low thermal loss. A rational use of thermal and electrical energy, no need of manual operations.
Low Maintenance Costs:
Deriving from simple and rational construction, simple automatic devices, and anticorrosive material.
