Abstract:
1. A beverage dispenser, comprising: a water tank comprising water therein; a primary cooling device in communication with the water tank, wherein the primary cooling device is configured to cool the water with the water tank; a carbonator disposed within the water tank, wherein the carbonator is configured to manufacture a carbonated beverage from carbonic acid gas and beverage ingredients; a beverage supply circuit in communication with the carbonator, wherein the beverage supply circuit is configured to supply the carbonated beverage to a nozzle; a supercooling heat exchanger in communication with the beverage supply circuit; a secondary cooling device in communication with the supercooling heat exchanger, wherein the secondary cooling device is configured to cool the carbonated beverage flowing through the beverage supply circuit into a supercooled state at a temperature of a solidifying point or less; a carbonic acid gas source; a gas supply line in communication with the carbonic acid gas source and the carbonator; a gas regulator disposed along the gas supply line between the carbonic acid gas source and the carbonator, wherein the gas regulator comprises: an exhaust valve disposed along the gas supply line downstream of the gas regulator, wherein the beverage supply circuit is maintained at the second pressure after the carbonated beverage is served, and wherein a pressure in the carbonator is set to the first pressure when the carbonated beverage in the beverage supply circuit is brought into an unsaturated state.
