A granulator device ( 1 ) for the treatment of powdered products comprises at least one closed container ( 2 ) forming a chamber ( 3 ) for treatment of the products; filter elements ( 4, 5 ) projecting into the treatment chamber ( 3 ), the filter elements ( 4, 5 ) comprising at least one multi-layer filtering wall ( 5 ) through which at least one fluid current can pass; and powder removing parts ( 6; 7, 8, 9, 10, 11 ) designed to diffuse at least one service fluid directed towards the filtering wall ( 5 ); the powder removing parts ( 6; 7, 8, 9, 10, 11 ) comprising at least a first arm ( 10 ) mobile relative to the filtering wall ( 5 ) and fitted with a set of first diffuser nozzles ( 7 ), the set of first nozzles ( 7 ) being positioned on the first arm ( 10 ) in such a way that it gradually covers the length of the surface of the filtering wall ( 5 ), as the arm ( 10 ) moves, diffusing the service fluid so as to free the filtering wall ( 5 ) of the powders trapped in it.
