Abstract:

A method and apparatus for transferring comminuted product from an unpressurized storage unit to a tank, especially a trailer-mounted tank. According to this method, an inert gas source is provided, preferably mounted on the trailer, and a conduit is provided to carry the product, which conduit is connected between the storage unit and the tank. The tank and conduit are evacuated so as to create a pressure differential between the storage unit and the tank, and the inert gas is allowed to flow into the evacuated tank in response to the partial vacuum therein. The product is then allowed to flow through the conduit to the tank in response to the partial vacuum therein. An improved trailer for receiving comminuted product according to a practice of the method is also disclosed.
