Abstract

A vacuum fill system for deaerating flowable material includes a cylindrical container partitioned into a plurality of chambers which rotate sequentially and which are connected to a vacuum pump for establishing a vacuum when filled with flowable material. The flowable material deaerates and compacts when atmospheric pressure is subsequently restored.
