Abstract

An aseptic product dispensing system generally includes a sanitary connection assembly interposed in fluid communication with a substantially conventional aseptic product source and a substantially conventional product dispenser. The sanitary connection assembly is provided with an automated cleaning system whereby a combination of pressurized gas, flushing fluid and/or sanitizing solution may be injected into, and thereafter evacuated from, the sanitary connection assembly.

Claims

1. A sanitary connection assembly for providing substantially aseptic fluid communication between an aseptic product source and a conventional product dispenser, said sanitary connection assembly comprising:

a cavernous body, said cavernous body having a first cavity portion interior thereto;

an outlet from said first cavity portion, said outlet being adapted to interface with a product dispenser;

a flow port into said first cavity portion from a second cavity portion, said flow port being arranged generally opposite said outlet;

a valve for controlling fluid flow through said flow port, said valve being adapted to selectively allow fluid flow through said flow port from without said first cavity portion and to prevent fluid flow through said flow port from within said first cavity portion; and

wherein said cavernous body is adapted for flushing of said second cavity portion independently of said first cavity portion.

2. The sanitary connection assembly as recited in claim 1, wherein cavernous body is further adapted for flushing of said first cavity portion substantially simultaneously with said second cavity.

3. The sanitary connection assembly as recited in claim 1, wherein said second cavity comprises a cannular projection from said flow port, said cannular projection having a central product aperture and being adapted to pierce a protective covering over a hose connector, thereby establishing a fluid pathway from a product hose to said flow port.

4. The sanitary connection assembly as recited in claim 3, wherein said second cavity further comprises an annular flushing cavity about said cannular projection.

5. The sanitary connection assembly as recited in claim 4, wherein said cavernous body comprises a flushing inlet for providing fluid communication of a cleaning fluid to said annular flushing cavity.

6. The sanitary connection assembly as recited in claim 5, wherein said cavernous body further comprises a drain port from said annular flushing cavity for evacuation of the cleaning fluid from said annular flushing cavity.

7. The sanitary connection assembly as recited in claim 6, wherein said drain port projects into said central product aperture substantially adjacent to said flow port.

8. The sanitary connection assembly as recited in claim 5, said sanitary connection assembly further comprising:

a hose connector for joining a product hose to said cavernous body; and

wherein said hose connector cooperates with said cavernous body to form said second cavity.

9. The sanitary connection assembly as recited in claim 8, wherein said annular flushing cavity is arranged to project fluids passed through said flushing inlet toward an interior face of said hose connector.

10. The sanitary connection assembly as recited in claim 9, said sanitary connection assembly further comprising an automated cleaning system.

11. The sanitary connection assembly as recited in claim 10, wherein said automated cleaning system comprises a source of pressurized sanitizing solution and a source of pressurized flushing fluid, each said source being in selective fluid communication with said flushing inlet.

12. The sanitary connection assembly as recited in claim 11, wherein said flushing fluid comprises water.

13. The sanitary connection assembly as recited in claim 11, wherein said automated cleaning system further comprises a source of pressurized gas, said source of pressurized gas being in selective fluid communication with said flushing inlet.

14. The sanitary connection assembly as recited in claim 13, wherein said pressurized gas comprises carbon dioxide.

15. The sanitary connection assembly as recited in claim 14, wherein said pressurized gas consists essentially of carbon dioxide.

16. The sanitary connection assembly as recited in claim 11, wherein said automated cleaning system comprises a controller, said controller being adapted to selectively flow said sanitizing solution and said flushing fluid through said flushing inlet.

17. The sanitary connection assembly as recited in claim 16, wherein said controller is further adapted to regulate the pressure with which said sanitizing solution and said flushing fluid are flowed through said flushing inlet.

18. The sanitary connection assembly as recited in claim 17, wherein said controller is adapted to regulate flow of said sanitizing solution and said flushing fluid at a first pressure and a second pressure, said first pressure being insufficient to dislodge said valve from said flow port and said second pressure being sufficient to dislodge said valve from said flow port.

19. The sanitary connector assembly as recited in claim 16, wherein said automated cleaning system further comprises a check valve, said check valve being arranged to prevent flow from within said cavernous body to said sources.

20. The sanitary connection assembly as recited in claim 19, wherein said automated cleaning assembly further comprises a plurality of solenoid valves, said solenoid valves being adapted to control flows from said sources to said flushing inlet.
