Abstract
A carbonated drink dispensing system includes a carbonation tank, a CO2 cylinder configured to deliver CO2 to the carbonation tank at a pressure of between 50 psi and 60 psi, a low-pressure pump configured to pump water into the carbonation tank, and a level sensor configured to determine when the water in the carbonation tank has reached a pre-determined level. The low-pressure pump is configured to stop pumping water when the level sensor determines that the water in the carbonation tank has reached the pre-determined level. The low-pressure pump starts pumping water again after a time delay.
Claims18
A carbonated drink dispensing system, comprising:
- a carbonation tank;
- a CO2 cylinder configured to deliver CO2 to the carbonation tank at a pressure of between 50 PSI and 60 PSI;
- a low-pressure pump configured to pump water into the carbonation tank;
- a level sensor configured to determine when the water in the carbonation tank has reached a pre-determined level;
- and
- a controller,
- wherein the low-pressure pump is configured to stop pumping water when the level sensor determines that the water in the carbonation tank has reached the pre-determined level,
- wherein the low-pressure pump starts pumping water after a time delay, and
- wherein the controller is configured to determine the time delay based on a desired concentration of CO2 to water.
A carbonated drink dispensing system comprising:
- a carbonation tank;
- a low-pressure pump configured to pump water into the carbonation tank;
- a level sensor configured to determine when the water in the carbonation tank has reached a pre-determined level;
- beverage dispensing valves operatively connected to the carbonation tank;
- a plurality of gas pumps configured to pump beverage concentrate to the beverage dispensing valves;
- a CO2 cylinder;
- and
- a pressure regulator configured to deliver CO2 from the CO2 cylinder to the carbonation tank at a first pressure and from the CO2 cylinder to the plurality of gas pumps at the first pressure,
- wherein the low-pressure pump is configured to stop pumping water when the level sensor determines that the water in the carbonation tank has reached the pre-determined level, and
- wherein the low-pressure pump starts pumping water after a time delay that is based on a desired concentration of CO2 to water.
