Mixing nozzle for a blended beverage for a multiple flavor beverage dispensing system
A beverage dispensing mixing nozzle for mixing a multi-component beverage mixture. The nozzle has a disruption plate for slowing and dispersing a dispensed fluid into an adjacent expansion region. The disruption plate and floor of the expansion region have turbulence-inducing surfaces to aid in mixing the fluid.
1. A beverage dispensing nozzle comprising:
an entry chamber adapted to connect with a beverage dispenser outlet, the entry chamber having a first internal wall having a first inner diameter, the first internal wall extending along an axis from a fluid entrance;
an expansion chamber in fluid communication with the entry chamber and having a second inner wall extending along the axis from the first internal wall, the second inner wall having a second inner diameter, the second inner diameter being greater than the first inner diameter;
an exit chamber in fluid communication with the expansion region and having a third internal wall extending along the axis from the second internal wall, the third internal wall having a third inner diameter that is less than the second inner diameter, the third internal wall extending along the axis to a fluid exit; and
a fluid stream disruption plate extending across the axis at a position between the expansion chamber and the exit chamber
wherein the second inner wall and fluid stream disruption plate have a turbulence-inducing surface; and
wherein the fluid stream disruption plate has a central opening.
2. The beverage dispensing nozzle of claim 1 wherein the fluid stream disruption plate has at least one vent apart from the central opening.
3. The beverage dispensing nozzle of claim 1 wherein the fluid stream disruption plate has a plurality of vents circumferentially encircling the central opening.
4. The beverage dispensing nozzle of claim 3 wherein the each of the plurality of vents is an arced slot.
5. The beverage dispensing nozzle of claim 3 wherein the fluid stream disruption plate is funnel shaped.
6. The beverage dispensing nozzle of claim 4 wherein at least a portion of the third inner wall is funnel shaped.
7. The beverage dispensing nozzle of claim 6 wherein the second inner wall is curved as it extends from the first inner wall away from the axis and is angled toward the axis as it extends to the third inner wall in the direction of the fluid exit.
8. The beverage dispensing nozzle of claim 7 wherein a portion of the third inner wall is funnel shaped as it extends from the second inner wall and toward the fluid exit.
9. The beverage dispensing nozzle of claim 8 wherein the portion of third inner wall has a turbulence-inducing surface.
10. The beverage dispensing nozzle of claim 9 wherein the turbulence-inducing surface is a stepped surface.
11. The beverage dispensing nozzle of claim 9 wherein the turbulence-inducing surface is a ridged surface.
12. The beverage dispensing nozzle of claim 9 wherein the turbulence-inducing surface is a dimpled surface.
13. The beverage dispensing nozzle of claim 9 wherein the turbulence-inducing surface is a roughened surface.
