Abstract
A vacuum fill system for deaerating flowable materials for storage in a receiving container comprising a hollow tubular container having a generally horizontal axis for receiving and holding flowable material. A vacuum pump or venturi and suitable valving are used to first create a vacuum within the chamber and then to return the chamber to atmospheric pressure instantaneously, thereby compacting the flowable material. An auger extends from the inlet end of the tubular container to the outlet end of the tubular container for moving flowable material into and compacted material out of the tubular container into a receiving container.
