Abstract: An enclosed vessel assembly for transporting and storing unpackaged materials is disclosed. An aluminum vessel is inserted into an openable end of a conventional steel shipping container, and secured therein such that unpackaged goods may be efficiently and inexpensively transported and stored using such containers. The aluminum vessel includes a rigid, elongated, closed-ended, cylindrical aluminum body having a rear end which is accessible through the openable end of the shipping container. Disposed on the rear end of the body of the vessel are a fill pipe through which unpackaged materials may be loaded into the vessel assembly, a conical discharge assembly for enabling a pneumatic tank trailer to be connected thereto to extract unpackaged materials from the vessel assembly, and at least one vent for facilitating the extraction of goods through the discharge assembly using a pneumatic tank trailer.

Abstract: Method and system unloads dry bulk materials from a tank hopper supported on a trailer, the trailer being connected to a tractor. A material conveying conduit is adapted for receiving material from the hopper. A blower is provided for supplying pressurized air to the hopper and to the conduit so that a pressure differential is created between the hopper and the conduit to thereby induce the flow of the materials from the hopper to the conduit. The pressurized air is cooled via a radiator which transfers heat from the pressurized air to ambient air. Ambient air is caused to flow across the radiator by a fan that is electrically driven by a battery located on the tractor, and that is automatically controlled by a pressure sensor switch positioned for sensing the pressure of the pressurized air stream.
