Claims21
A system for dispensing a cooled beverage, comprising:
- a liquid/gas contactor unit;
- a beverage pump;
- a beverage tank in liquid communication with the liquid/gas contactor unit through the beverage pump, wherein the beverage tank is pressurized;
- a cooling or refrigeration system configured to cool the beverage tank, wherein the beverage pump is configured to transfer a cooled noncarbonated beverage from the beverage tank to the liquid/gas contactor unit;
- a controlled pressurized supply of a regulated pressure nitrogen gas comprising at least 50% by weight nitrogen (N2);
- one or more secondary regulators for feeding the regulated pressure nitrogen gas to the liquid/gas contactor unit and the beverage pump, wherein the cooled noncarbonated beverage contacts the regulated pressure nitrogen gas in the liquid/gas contactor unit to dissolve the regulated pressure nitrogen gas in the cooled noncarbonated beverage to form a cooled nitrogen-infused noncarbonated beverage;
- and
- a beverage faucet attached downstream to the liquid/gas contactor unit configured to dispense the cooled nitrogen-infused noncarbonated beverage at a controlled rate.

A system for dispensing a cooled beverage, comprising:
- a liquid/gas contactor unit;
- a beverage pump;
- a bag-in-box beverage container in liquid communication with the liquid/gas contactor unit through the beverage pump, wherein the beverage pump is configured to transfer a noncarbonated beverage from the bag-in-box beverage container to the liquid/gas contactor unit;
- a cooling or refrigeration system configured to cool the bag-in-box beverage container;
- a controlled pressurized supply of a regulated pressure nitrogen gas comprising at least 50% by weight nitrogen (N2);
- one or more secondary regulators for feeding the regulated pressure nitrogen gas to the liquid/gas contactor unit and the beverage pump, wherein the noncarbonated beverage contacts the regulated pressure nitrogen gas in the liquid/gas contactor unit to dissolve the regulated pressure nitrogen gas in the noncarbonated beverage to form a cooled nitrogen-infused noncarbonated beverage;
- and
- a beverage faucet attached downstream to the liquid/gas contactor unit configured to dispense the cooled nitrogen-infused noncarbonated beverage at a controlled rate.
5 more elements
