ABSTRACT:
A system unloads material, such as bulk quantities of dry product, from a container, such as a railroad hopper car, in a fast and efficient manner. The container defines an interior adapted to contain a product and includes a product discharge section adapted to allow the product to pass therethrough. The material unloading system includes a product outlet line adapted to communicate with the product discharge section. The product outlet line includes a product outlet adapted to allow the product to pass therethrough. A source of pressurized fluid communicates with the product outlet line and is adapted to move product from the product discharge section to the product outlet. A source of vacuum communicates with the product outlet and is adapted to unload the product from the product outlet.
