Abstract
The present invention pertains to a method and an installation or system for drying fibrous material. The method comprises the step of ventilating very moist air through the fibrous material located in a drying zone. The moisture content of the moist air is less than that inside the drying zone, its pressure is close to atmospheric pressure and its temperature is higher than that of the material to be dried. The method additionally comprises the step of recovering the heat of condensation of the water vapor extracted from the fibrous material to heat the moist air, providing leaks between the outside ambient air and the ventilation circuit upstream and downstream of the drying zone, making possible a mass and heat exchange. It is possible to ensure heat and mass balance without expelling large amounts of moist air into the ambient air.
