Abstract

A beverage mixing assembly for mixing a gas into a liquid to thereby form a solution includes a mixer body having a first upstream inlet configured to receive the gas, a second upstream inlet configured to receive the liquid, and a downstream outlet configured to dispense the solution from the mixer body. The first upstream inlet defines a first orifice configured to spray the gas into the mixer body and the second upstream inlet defines a second orifice configured to spray the liquid into the mixer body such that the gas collides into the liquid as the liquid conveys from the second upstream inlet to the downstream outlet to thereby mix into the liquid and form the solution.

First claim

What is claimed is:

1. A beverage mixing assembly for mixing a gas into a liquid to thereby form a solution, the beverage mixing assembly comprising:
a mixer body comprising:
a first upstream inlet configured to receive the gas, the first upstream inlet defining a first orifice configured to spray the gas into the mixer body;
a second upstream inlet configured to receive the liquid, the second upstream inlet defining a second orifice configured to spray the liquid into the mixer body; and
a downstream outlet configured to dispense the solution from the mixer body;
a pressure drop device positioned upstream of the first upstream inlet and configured to reduce the pressure of the gas received by the first upstream inlet; and
a check valve positioned upstream of the first upstream inlet and downstream of the pressure drop device, wherein the check valve prevents liquid sprayed by the second orifice from entering the pressure drop device;
wherein the gas collides into the liquid as the liquid conveys from the second upstream inlet to the downstream outlet to thereby mix into the liquid and form the solution.

2. The beverage mixing assembly according to claim 1 , wherein the first upstream inlet is axially opposite the second upstream inlet and the downstream outlet extends transversely to the first upstream inlet.

3. The beverage mixing assembly according to claim 1 , wherein the mixer body is configured so that a pressure of the liquid downstream of the second orifice is equal to a pressure of the gas downstream of the first orifice.

4. The beverage mixing assembly according to claim 3 , wherein a diameter of the first orifice is between 0.5 millimeters and 1.5 millimeters, and wherein a diameter of the second orifice is between 1.5 millimeters and 3.0 millimeters.

5. The beverage mixing assembly according to claim 4 , wherein the mixer body comprises a “T”-pipe having an inner pipe diameter between 5.0 millimeters and 10.0 millimeters.

6. The beverage mixing assembly according to claim 5 , wherein the mixer body comprises a third orifice at the downstream outlet, the third orifice having a diameter between 2.0 millimeters and 4.0 millimeters, and wherein a flow path from the first and second orifices to the third orifice is unobstructed.

7. The beverage mixing assembly according to claim 1 , further comprising a chiller positioned downstream of the mixer body and configured to cool the solution.

8. The beverage mixing assembly according to claim 1 , further comprising:
a gas supply configured to provide the gas to the first upstream inlet; and
a liquid supply configured to provide the liquid to the second upstream inlet;
wherein the gas is connected to the liquid supply to pressurize the liquid in the liquid supply with the gas from the gas supply.

9. The beverage mixing assembly of claim 8 , wherein the pressure drop device comprises a flow rate regulator positioned between the gas supply and the first orifice and positioned between the gas supply and the liquid supply.

10. A beverage mixing assembly for mixing a gas into a liquid to thereby form a solution, the beverage mixing assembly comprising:
a mixer body comprising:
a first upstream inlet configured to receive the gas, the first upstream inlet defining a first orifice configured to spray the gas into the mixer body;
a second upstream inlet configured to receive the liquid, the second upstream inlet defining a second orifice configured to spray the liquid into the mixer body; and
a downstream outlet configured to dispense the solution from the mixer body;
a capillary tube positioned upstream of the first upstream inlet and configured to reduce the pressure of the gas received by the first upstream inlet; and
a check valve positioned upstream of the first upstream inlet and downstream of the capillary tube, wherein the check valve prevents liquid sprayed by the second orifice from entering the capillary tube;
wherein the gas collides into the liquid as the liquid conveys from the second upstream inlet to the downstream outlet to thereby mix into the liquid and form the solution.

11. The beverage mixing assembly of claim 10 , further comprising:
a gas supply configured to provide the gas to the first upstream inlet; and
a liquid supply configured to provide the liquid to the second upstream inlet;
wherein the gas is connected to the liquid supply to pressurize the liquid in the liquid supply with the gas from the gas supply.

12. The beverage mixing assembly of claim 11 , further comprising a flow rate regulator positioned between the gas supply and the liquid supply.

13. The beverage mixing assembly of claim 10 , further comprising a chiller positioned downstream of the mixer body and configured to cool the solution.

14. A beverage mixing assembly for mixing a gas into a liquid to thereby form a solution, the beverage mixing assembly comprising:
a mixer body including a “T”-pipe having an inner pipe diameter between 5.0 millimeters and 10.0 millimeters, the mixer body further comprising:
a first upstream inlet configured to receive the gas, the first upstream inlet defining a first orifice configured to spray the gas into the mixer body, wherein a diameter of the first orifice is between 0.5 millimeters and 1.5 millimeters;
a second upstream inlet configured to receive the liquid, the second upstream inlet defining a second orifice configured to spray the liquid into the mixer body, wherein a diameter of the second orifice is between 1.5 millimeters and 3.0 millimeters; and
a downstream outlet configured to dispense the solution from the mixer body, the downstream outlet comprising a third orifice having a diameter between 2.0 millimeters and 4.0 millimeters;

wherein the gas collides into the liquid as the liquid conveys from the second upstream inlet to the downstream outlet to thereby mix into the liquid and form the solution;
wherein the mixer body is configured so that a pressure of the liquid downstream of the second orifice is equal to a pressure of the gas downstream of the first orifice; and
wherein the flow path from the first and second orifices to the third orifice is unobstructed.

15. The beverage mixing assembly of claim 14 , wherein the first upstream inlet is axially opposite the second upstream inlet and the downstream outlet extends transversely to the first upstream inlet.

16. The beverage mixing assembly according to claim 14 , further comprising a pressure drop device positioned upstream of the first upstream inlet and configured to reduce the pressure of the gas received by the first upstream inlet.

17. The beverage mixing assembly according to claim 14 , further comprising:
a gas supply configured to provide the gas to the first upstream inlet; and
a liquid supply configured to provide the liquid to the second upstream inlet;
