Abstract

Systems and methods for filling a beverage container with a carbonated fluid at ambient temperature while minimizing foam formation are provided. The carbonated fluid can maintain a laminar flow through the filling machine.

First claim

What is claimed is:

1. A method of producing a container filled with a carbonated fluid product, the method comprising:
retaining treated water in a water tank;
deaerating the water tank using a vacuum pump;
mixing the treated water with a concentrate to create a fluid mixture;
injecting the fluid mixture with carbon dioxide to create the carbonated fluid product;
storing the carbonated fluid product in a carbonized tank that is fluidly connected to a filling machine;
operating the filling machine to fill the container with the carbonated fluid product,
wherein the treated water, fluid mixture, and carbonated fluid product are maintained at an ambient temperature.

2. The method of claim 1 , wherein the fluid product is not cooled before entering the filling machine.

3. The method of claim 1 , wherein the vacuum pump generates a negative pressure of at least approximately 0.8 bar to deaerate the water tank.

4. The method of claim 1 , wherein the injecting the fluid mixture with carbon dioxide occurs at a pressure within a range of approximately 3.2 bar to approximately 4.2 bar.

5. The method of claim 1 , wherein an interior pressure of the carbonized tank is approximately 5.5 bar.

6. The method of claim 5 , wherein an interior pressure of the filling machine is approximately 5 bar.

7. The method of claim 1 , wherein an interior pressure of the carbonized tank is approximately 0.5 bar higher than an interior pressure of the filling machine.

8. The method of claim 1 , wherein the treated water, fluid mixture, and carbonated fluid product have a laminar flow.

9. The method of claim 1 , wherein the ambient temperature is approximately 15 degrees Celsius.

10. A method of producing a container filled with a carbonated fluid product, the method comprising:
retaining treated water at an ambient temperature in a water tank;
deaerating the water tank using a vacuum pump to create a negative pressure of at least 0.8 bar;
mixing the treated water with a concentrate to create a fluid mixture;
injecting the fluid mixture with carbon dioxide at a pressure in a range of approximately 3.2 bar to approximately 4.2 bar to create the carbonated fluid product;
storing the carbonated fluid product in a carbonized tank that is fluidly connected to a filling machine, the carbonized tank having an interior pressure of approximately 5.5 bar;
operating the filling machine to fill the container with the carbonated fluid product, the filling machine having an interior pressure of approximately 5 bar, and the carbonated fluid product being at the ambient temperature.

11. The method of claim 10 , wherein the filling machine comprises:
a support housing having an upper surface and a lower surface defining an inner fluid chamber for supplying the fluid material to be discharged into the container;
a valve housing mounted to the lower surface for controlling the discharge of the fluid material;
a vent tube having a first end and a second end, the second end at least partially extending through the valve housing;
an umbellate ring surrounding the vent tube and being positioned adjacent the second end of the vent tube;
a spring positioned about the first end of the vent tube; and
a fluid sealing mechanism positioned adjacent to the upper surface and operating with the spring to control fluid flow into the beverage container.
