Patent ID: 10077418

Abstract:
A system and method for carbonating a beverage is shown. The system includes a saturation tank having a gas head space of CO2, a carbonation tank, and a beverage supply system to pass the beverage between the saturation tank and the carbonation tank. A beverage supersaturated with CO2 from the head space is formed in the saturation tank. The supersaturated beverage is passed from the saturation tank to the carbonation tank. Once the amount of CO2 added to the beverage exceeds saturation, some of the CO2 escapes from solution from the beverage and the pressure in the carbonation tank increases. Once the pressure within the carbonation tank reaches a pre-defined pressure for the desired volume CO2/volume beverage, a pump supplying the beverage to the saturation tank is shut-off and the inlet and outlet valves of the carbonation tank are closed.
