<p>The storage silo is fitted with a lid at the top and a grid (4) at the base. The silo is fitted with an electrical or pneumatic vibrator. The support arm (6) is hinged to one of the legs. The arm carries the dispenser, which is fixed by the hydraulic jack (10). The dispenser has a number of internal distribution valves and is connected to the air line and a product delivery pipe. The silo is filled through the central filling pipe, and is fitted to a vacuum pump to maintain constant internal pressure. The casing of the dispenser (12) holds a perforated disc (15) above a honeycomb-structure disc (14). A rubber seal (16) is interposed between the two discs. The honeycomb disc is rotated so that the cells are successively moved from a compressed air discharge tube to a product exit tube.</p> |
