a restrictor device configured to decrease pressure of the reconstituted beverage, wherein the restrictor device is adjustable to thereby change the pressure of the reconstituted beverage; and
a dispensing valve configured to dispense the reconstituted beverage.
9. The beverage dispenser of claim 8 , further comprising a lock-out system configured to stop flow of the concentrate when the pressure of the gas-infused liquid is less than a minimum pressure and prevent the reconstituted beverage from being dispensed with an unsafe amount of the concentrate.
10. The beverage dispenser of claim 8 further comprising a pump configured to increase pressure of the one of the gas-infused liquid and the concentrate before the flow control device decreases the pressure of the one of the gas-infused liquid and the concentrate.
11. A beverage dispenser comprising:
a mixing chamber in which a gas-infused liquid and a concentrate are mixed to form a reconstituted beverage;
a first flow control device configured to decrease pressure of the gas-infused liquid before the gas-infused liquid and the concentrate are mixed;
a second flow control device configured to decrease pressure of the concentrate before the gas-infused liquid and the concentrate are mixed;
a pump configured to increase the pressure of the one of the gas-infused liquid and the concentrate before the flow control device decreases the pressure of the one of the gas-infused liquid and the concentrate such that the flow control device properly dispenses the one of the gas-infused liquid and the concentrate at the first flow rate and the reconstituted beverage is properly formed; and
a dispensing valve configured to dispense the reconstituted beverage.
12. The beverage dispenser according to claim 11 ,
wherein the pump is a first pump configured to increase the pressure of the gas-infused liquid before the first flow control device decreases the pressure of the gas-infused liquid such that the first flow control device dispenses the gas-infused liquid at a first flow rate;
and further comprising:
a second pump configured to increase the pressure of the concentrate before the second flow control device decreases the pressure of the concentrate such that the second flow control device dispenses the concentrate at a second flow rate.
13. The beverage dispenser according to claim 12 , wherein the second flow rate is less than the first flow rate such that the reconstituted beverage has a predetermined fluid ratio.
14. The beverage dispenser according to claim 11 , wherein the first flow control is configured to dispense the gas-infused liquid at a first flow rate and the second flow control is configured to dispense the concentrate at a second flow rate that is less than the first flow rate such that the reconstituted beverage has a predetermined fluid ratio.
15. The beverage dispenser according to claim 11 , further comprising a restrictor device configured to decrease pressure of the reconstituted beverage.
16. The beverage dispenser according to claim 11 , further comprising a lock-out system configured to stop flow of the concentrate when the pressure of the gas-infused liquid is less than a minimum pressure and thereby prevent the reconstituted beverage from being dispensed with an unsafe amount of the concentrate.
