Method and device for treating a mixture of expansion gas and filling product foam in a beverage filling plant

1. A method for treating a mixture of an expansion gas and a fill product foam in a beverage filling plant, comprising the steps of:

removing the mixture of the expansion gas and the fill product foam from a fill product;

introducing the mixture into a closed separation container after the mixture is removed from the fill product; and

extracting the expansion gas out of the closed separation container via suction.

2. The method of claim 1 , further comprising sprinkling a fluid medium on the mixture after the mixture is introduced into the closed separation container.

3. The method of claim 2 , wherein the sprinkling comprises applying the fluid medium by using a sprinkler nozzle that is accommodated in the closed separation container.

4. The method of claim 3 , wherein the extracting comprises using suction above the sprinkler nozzle to extract the expansion gas.

5. The method of claim 2 , wherein the sprinkling comprises extracting the fluid medium from a lower area of the closed separation container and recirculating the fluid medium, and wherein the lower area of the closed separation container comprises a sump.

6. The method of claim 2 , further comprising periodically conveying the fluid medium and the fill product foam out of the closed separation container.

7. The method of claim 1 , wherein the introducing comprises tangentially introducing the mixture into the closed separation container.

8. The method of claim 1 , further comprising cleaning the closed separation container.

9. The method of claim 8 , wherein the cleaning comprises:

spraying at least one of a cleaning medium and a sterilizing medium onto an interior wall of the closed separation container; and

conducting at least one of the cleaning medium and the sterilization medium out of a lower area of the closed separation container.

10. A device for performing the method of claim 1 , the device comprising:

the closed separation container, wherein the closed separation container is configured to be coupled to a relief line to receive the mixture into the closed separation container and configured to be coupled to a suction extractor so that the expansion gas is extracted from the closed separation container via suction from the suction extractor.

11. The device of claim 10 , further comprising a sprinkler nozzle disposed in the closed separation container, wherein the sprinkler nozzle applies a fluid medium to the mixture of the expansion gas and the fill product foam that is present in the closed separation container.

12. The device of claim 11 , wherein a lower area of the closed separation container comprises an outlet.

13. The device of claim 12 , wherein the outlet is in fluid communication with the sprinkler nozzle so that the fluid medium recirculated from the lower area of the closed separation container to the sprinkler nozzle.

14. The device of claim 12 , wherein the lower area of the closed separation container comprises a sump.

15. The device of claim 11 , further comprising the suction extractor, wherein the suction extractor is in fluid communication with the closed separation container and is disposed above the sprinkler nozzle.

16. The device of claim 10 , wherein the closed separation container is at least substantially cylindrical and/or substantially conical.

17. The device of claim 10 , further comprising the relief line, wherein the relief line is tangentially coupled to the closed separation container.

18. The device of claim 10 , further comprising a clean-in-place (CIP) nozzle provided in the closed separation container, wherein the CIP nozzle is configured to impinge on an interior wall of the closed separation container with a CIP medium.

19. The device of claim 18 , further comprising

a CIP return line that is in fluid communication with a lower area of the closed separation container.

20. The method of claim 1 , wherein the mixture consists of the expansion gas and the fill product foam.
