Abstract
A system and method to prepare and dispense a N2 or N2/CO2 gas infused chilled beverage is provided. The beverage may be any non-carbonated liquid and in one embodiment the beverage is coffee. The dispensed N2 or N2/CO2 gas infused chilled coffee has a unique appearance and enhanced flavor and aroma. The system may be provided as a self-contained unit.
Claims25
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.
5 more elements
A chilled dispensed N2 or N2/CO2 infused beverage obtained by a method comprising:
- charging a noncarbonated beverage to a beverage tank which is in liquid communication with a liquid/gas contactor unit through a beverage pump;
- chilling the noncarbonated beverage to a temperature of from 30 to 40° F.;
- feeding a supply of N2 to the liquid/gas contactor unit, beverage pump and to the beverage tank through one or more secondary regulators;
- adjusting the one or more secondary regulators to supply the N2 at a pressure of from 20 to 70 psi at the liquid/gas contactor unit and beverage pump;
- pressurizing the beverage tank to 10-12 psi;
- pumping the chilled noncarbonated beverage from the beverage tank through the beverage pump to the liquid/gas contactor unit;
- contacting the chilled noncarbonated beverage with N2 in the liquid/gas contactor unit to dissolve the N2 in the chilled noncarbonated beverage to obtain a chilled nitrogen-infused noncarbonated beverage;
- and
- dispensing the chilled nitrogen-infused noncarbonated beverage through a beverage faucet at a controlled rate to a receiver.
6 more elements
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.
