Abstract (en)
Plant and method for pelletizing a granular and/or powder material and for drying of the extruded pellets. A closed system circulating drying air is used, thus making the use of a filter superfluous by eliminating the risk of dispersing powders, micro-powders, polluting substances and bad odours in the environment. The plant comprises a closed circuit (10) for circulating a drying air flow, wherein a flow of pellets to be dried is inserted, said closed circuit comprising an air flow pumping device (12), an air cooling device (13), a device (14) for condensing the humidity transported by the air flow, and a device (16) for extracting the resulting water, so as to obtain an air flow with reduced water content, and a drying chamber (5), wherein the air flow with reduced water content intersects said flow of pellets to be dried.
