A vacuum fill system for deaerating and compacting flowable materials within a container for transportation and storage of the materials includes a hollow chamber having an open bottom end for insertion of the chamber into the container. A rubber pad placed under the container seals the chamber for creation of a vacuum in the chamber through a vacuum line connecting the chamber to a vacuum source for deaeration of flowable materials placed within the chamber and the container. A line having a valve therein and vented to the atmosphere is connected to the chamber for returning the chamber to atmospheric pressure substantially instantaneously to compact the deaerated material into a substantially solid mass within the container. Upon completion of compaction the chamber of the vacuum fill system is removed from the interior of the container and the top of the container closed for shipment or storage.

A vacuum fill system for deaerating and compacting flowable material for storage and transportation in a flexible bulk container, the flexible bulk container having a bottom and sidewall, said vacuum fill system comprising: a base for supporting the flexible bulk container wherein the base is positioned below the flexible bulk container; a hollow chamber having a sidewall, a top wall, and an open bottom, said hollow chamber being inserted in the flexible bulk container such that the open bottom of the hollow chamber contacts the bottom of the flexible bulk container; means for creating a vacuum connected to the hollow chamber, said means for creating a vacuum drawing a vacuum from the inside of the flexible bulk container after the hollow chamber is inserted inside the flexible bulk container thereby deaerating the flowable material inside the flexible bulk container; and means for returning the chamber contents to atmospheric pressure substantially instantaneously to compact the deaerated material.
