Carbonation method
A method and apparatus for carbonating a liquid in a pressurizable vessel, including first connecting a vessel with a carbon dioxide tank, wherein said vessel contains a liquid. A vessel can then be pressurized with carbon dioxide to a desired pressure. A pump or compressor can be activated to circulate gas through a hose out of the head space of the vessel to a carbonating stone back into the vessel. After a pre-determined period of time the pump is deactivated, and the carbon dioxide can cease to be introduced to the liquid within the vessel.
1. A method of carbonating a liquid in a pressurizable vessel having a top end and a bottom end, comprising:
connecting the vessel to a first carbon dioxide tank and a pump, wherein said vessel contains a liquid;
pressurizing a carbonating stone positioned proximate to the bottom of the vessel at a desired first pressure with a first carbon dioxide gas from first the carbon dioxide tank;
introducing the first carbon dioxide gas to the liquid at the carbonation stone;
activating the pump to circulate the first carbon dioxide gas from a head space at the top end within the vessel to the carbonation stone within the vessel;
continually circulating the carbon dioxide gas within the head space back to the carbonation stone until the liquid reaches a desired carbonation saturation level;
deactivating the pump and disconnecting the vessel from the first carbon dioxide tank and pump.
2. The method of claim 1 , wherein the vessel is pressurized to a desired second pressure, wherein the second desired pressure can be provided utilizing at least one of the following: the first carbon dioxide gas from the first carbon dioxide tank or a second carbon dioxide gas from a second carbon dioxide tank.
3. The method of claim 2 , wherein the desired first pressure and desired second pressure are the same.
4. The method of claim 3 , wherein said second pressure is about 1 PSI greater than said first pressure.
5. The method of claim 2 , wherein said carbonating stone comprises pores having a diameter between about 0.5 microns and about 30 microns.
6. The method of claim 3 , wherein said carbonating stone comprises pores having a diameter between 10 and 20 microns.
7. The method of claim 6 , wherein the pore diameter is configured to reduce the ability to over carbonate the liquid past a pre-determined carbonation level.
8. The method of claim 1 , further comprising pressurizing the vessel to a desired second pressure, wherein the desired second pressure is less than the pressure applied to said carbonating stone.
9. The method of claim 1 , wherein the carbon dioxide bypasses the pump and is introduced to the vessel without circulating the gas.
