Vacuum fill system

A vacuum fill system for deaerating flowable materials comprising:

• a first rotatable chamber for receiving flowable materials;
• a fixed position hollow chamber connected to the first rotatable chamber for receiving flowable materials from the first rotatable chamber;
• means for creating a vacuum in the fixed position chamber for deaerating the flowable materials;
• a second rotatable chamber for receiving the deaerated flowable materials from the fixed position hollow chamber;
• means for creating a vacuum in the second rotatable chamber for maintaining the flowable materials in a deaerated state;
• means for returning the second rotatable chamber to atmospheric pressure substantially instantaneously to compact the deaerated flowable materials;
• and
• means for forcing the compacted deaerated flowable materials from discharge end of the second rotatable chamber into a receiving container wherein the discharge end of the second rotatable chamber is open to atmosphere.

A vacuum fill system for continuously deaerating flowable materials comprising:

• a first continuously rotatable airtight chamber valve for receiving flowable materials;
• a fixed position hollow chamber connected to the first rotatable chamber for receiving flowable materials from the first rotatable chamber;
• a vacuum source for creating a vacuum in the fixed position chamber for deaerating the flowable materials;
• a second continuously rotating airtight chamber valve having an exterior housing and an interior chamber wall defining an area for receiving deaerated flowable materials from the fixed position hollow chamber;
• a first opening in the housing of the second rotatable chamber and at least one valve connecting the vacuum source to the opening for creating a vacuum in the second rotatable chamber for maintaining the flowable materials in a deaerated state;
• at least one valve connecting the first opening in the second rotatable chamber to the atmosphere for returning the deaerated flowable material to atmospheric pressure substantially instantaneously to compact the deaerated flowable material;
• a second opening in the housing of the second rotatable chamber and at least one valve connecting the second opening to a compressed air source for forcing the compacted deaerated materials from the second rotatable chamber into a receiving container;
• and
• an opening in the interior chamber wall of the second rotatable chamber connected to the second opening in the housing for injecting compressed air into the second rotatable chamber.
