ABSTRACT:
An unloading system for transferring dry, bulk, particulate material from a ship, barge or the like to a conveyor system and ultimately to a storage silo. The particulate material is continuously transferred from the ship into a first pressure vessel or container which pressure vessel is operated under a constant vacuum or negative pressure. During the filling of the pressure vessel, particulate material is removed from the pressure vessel and sequentially transferred first to a temporary discharge container and then to a conveyor system. The alternating filling and emptying of discharge container continues while the pressure vessel is continuously filled.
