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. |
