The silo comprises a cylindrical tank (1), an Archimedes extraction screw (3) located in the lower part and a distributing disc (12) in the upper part driven by a motor (13). Piping (10) connects the extraction outlet to the distribution disc. The silo bottom is conical with a cone angle of about 5 degrees to allow cleaning by a water jet. An outlet hopper (4) in the silo bottom is connected to an Archimedes screw conveyor (5) in which an outlet (7) is connected to a venturi (8) supplied by a fan (9). The venturi outlet is connected to the piping whose second end (11) discharges inside the silo onto the distribution disc. The variable pitch radial toothed Archimedes extraction screw is rotated by a hydraulic system (3a).
