Abstract

A juice beverage dispenser employs a fixed ratio pump interposed between a source of juice concentrate and a source of water. The water drives the pump such that the water and juice concentrate outputs from the pump are presented in a fixed ratio independent of water pressure or juice concentrate viscosity. The outputs from the pump are passed to a check valve/premixer which blends the water and juice concentrate into a premixed blend for passage to a final mixer. A bypass line interconnects the source of water and the final mixer and has therein a metering valve with an adjustable orifice. By adjusting the orifice of the metering valve, the final ratio of juice concentrate and water in the final juice beverage may be established.

Claims

1. A juice beverage dispenser, comprising:

a source of juice concentrate;

a source of water;

a fixed ratio pump connected to said source of juice concentrate and water and producing outputs of juice concentrate and water in a set ratio characteristic of said pump;

mixing means connected to said outputs for receiving said juice concentrate and water and blending the same into a juice beverage; and

augmentation supply means interposed between one of said sources of juice and water and said mixing means for altering a ratio of juice concentrate and water in said juice beverage from said set ratio.

2. The juice beverage dispenser according to claim 1, wherein said augmentation supply means comprises a conduit having a metering valve therein.

3. The juice beverage dispenser according to claim 2, wherein said metering valve has an adjustable orifice.

4. The juice beverage dispenser according to claim 3, wherein said conduit is interposed between said source of water and said mixing means.

5. The juice beverage dispenser according to claim 2, wherein said mixing means comprises a static mixer.

6. The juice beverage dispenser according to claim 2, wherein said mixing means comprises a dynamic mixer.

7. The juice beverage dispenser according to claim 2, wherein said mixing means comprises a premixer connected to said outputs and blending said juice concentrate and water into a premixed juice beverage, and a conduit interconnecting said premixer and a final mixer, said conduit passing said premixed juice beverage from said premixer to said final mixer.

8. The juice beverage dispenser according to claim 7, wherein said augmentation supply means interconnects with said final mixer.

9. The juice beverage dispenser according to claim 7, wherein said premixer comprises a housing having first and second inlets respectively connected to said outputs of said fixed ratio pump, and an outlet connected to said conduit interconnecting said premixer and final mixer.

10. The juice beverage dispenser according to claim 9, wherein said housing receives a ball movable therein.

11. The juice beverage dispenser according to claim 10, wherein said first inlet has a seat adapted to receive said ball.

12. The juice beverage dispenser according to claim 11, wherein said seat comprises an O-ring, and further comprises a spring maintaining said O-ring at said first inlet, said ball being movable within said spring.

13. The juice beverage dispenser according to claim 12, wherein said spring has a tab at one end thereof, said tab precluding said ball from engaging said outlet.

14. The juice beverage dispenser according to claim 13, wherein said first inlet connects to said output of water of said fixed ratio pump.

15. The juice beverage dispenser according to claim 14, further comprising a check valve interposed between said output of juice concentrate and said second inlet.

16. A juice beverage dispenser, comprising:

a source of juice concentrate;

a source of water;

a fixed ratio pump connected to said sources and having outputs of water and juice concentrate presented in a fixed ratio;

a premixer receiving and blending said outputs of water and juice concentrate into a premixed juice beverage;

a final mixer connected to said premixer and receiving said premixed juice beverage; and

a conduit interconnected to one of said sources of juice and water with said final mixer, said conduit having a metering valve therein.

17. The juice beverage dispenser according to claim 16, wherein said metering valve is adjustable.

18. The juice beverage dispenser according to claim 17, wherein said premixer comprises a bail received within a housing, said ball agitating water and juice concentrate into said premixed juice beverage.

19. The juice beverage dispenser according to claim 18, wherein said ball seats against an inlet for said water.
