Abstract

A beverage dispensing system includes a nozzle assembly and a valve system, the nozzle assembly including a nozzle body having a diffuser chamber, a mixing chamber, and one or more cooling channels formed therein, a diffuser disposed within the diffuser chamber, and a manifold having one or more cooling channels formed therein and being configured to receive a flow of a base fluid and a flow of a concentrate for mixing of the base fluid and the concentrate in the mixing chamber to provide a beverage, and the valve system including one or more valves for regulating respective flow rates of each of the base fluid and the concentrate to substantially achieve a target mix ratio of the base fluid to concentrate within the mixing chamber.

First claim

What is claimed is:

1. A beverage dispensing system, comprising:
a nozzle assembly comprising:
a nozzle body having a diffuser chamber, a mixing chamber, and one or more cooling channels formed therein,
a diffuser disposed within the diffuser chamber and being fixed from movement within the nozzle body during operation of the beverage dispensing system, and
a manifold having one or more cooling channels formed therein and being configured to receive a flow of a base fluid and a flow of a concentrate for mixing of the base fluid and the concentrate in the mixing chamber to provide a beverage; and

a valve system comprising one or more valves for regulating respective flow rates of each of the base fluid and the concentrate to substantially achieve a target mix ratio of the base fluid to concentrate within the mixing chamber.

2. The beverage dispensing system of claim 1 , wherein at least one valve of the one or more valves is adjustable to adjust a mix ratio of the beverage to substantially achieve the target mix ratio.

3. The beverage dispensing system of claim 1 , wherein the diffuser is retained within the diffuser chamber by the manifold.

4. The beverage dispensing system of claim 1 , wherein at least a portion of the diffuser extends into the mixing chamber.

5. The beverage dispensing system of claim 1 , wherein the flow of concentrate travels through an interior of the diffuser and at least a portion of the flow of the base fluid travels around the diffuser for mixing of the base fluid and the concentrate substantially within the mixing chamber.

6. The beverage dispensing system of claim 1 , wherein the valve system comprises an on/off valve for each of the concentrate and the base fluid.

7. The beverage dispensing system of claim 1 , wherein the target mix ratio is specific to the beverage dispensed from the dispensing system.

8. The beverage dispensing system of claim 1 , wherein the concentrate comprises a beer concentrate and the base fluid comprises one of carbonated water and nitrogenated water.

9. The beverage dispensing system of claim 1 , wherein a concentrate source system comprises a manifold that the concentrate flows through.

10. The beverage dispensing system of claim 9 , wherein the concentrate is one of multiple concentrates that can selectively flow through the manifold within the concentrate source system.

11. A beverage dispensing system, comprising:
a nozzle assembly comprising:
a nozzle body having a mixing chamber and one or more first cooling channels formed therein,
a diffuser at least partially disposed within nozzle body and being fixed from movement within the nozzle body during operation of the beverage dispensing system, and
a manifold having one or more second cooling channels formed therein and being configured to receive a flow of a base fluid and a flow of a concentrate for mixing of the base fluid and the concentrate in the mixing chamber to provide a beverage, the one or more first cooling channels of the nozzle body and the one or more second cooling channels of the manifold defining independent cooling paths within the nozzle assembly; and

a valve system comprising one or more valves for regulating respective flow rates of each of the base fluid and the concentrate to substantially achieve a target mix ratio of the base fluid to concentrate within the mixing chamber.

12. The beverage dispensing system of claim 11 , wherein at least one valve of the one or more valves is adjustable to adjust a mix ratio of the beverage to substantially achieve the target mix ratio.

13. The beverage dispensing system of claim 11 , wherein the diffuser is retained within a diffuser chamber by the manifold.

14. The beverage dispensing system of claim 11 , wherein at least a portion of the diffuser extends into the mixing chamber.

15. The beverage dispensing system of claim 11 , wherein the flow of concentrate travels through an interior of the diffuser and at least a portion of the flow of the base fluid travels around the diffuser for mixing of the base fluid and the concentrate substantially within the mixing chamber.

16. The beverage dispensing system of claim 11 , wherein the valve system comprises an on/off valve for each of the concentrate and the base fluid.

17. The beverage dispensing system of claim 11 , wherein the target mix ratio is specific to the beverage dispensed from the dispensing system.

18. The beverage dispensing system of claim 11 , wherein the concentrate comprises a beer concentrate and the base fluid comprises one of carbonated water and nitrogenated water.

19. The beverage dispensing system of claim 11 , wherein a concentrate source system comprises a manifold that the concentrate flows through.

20. The beverage dispensing system of claim 19 , wherein the concentrate is one of multiple concentrates that can selectively flow through the manifold within the concentrate source system.
