Multiple flavor beverage dispenser
A beverage dispenser and methods of beverage dispensing include a dispenser with a beverage valve and a purge valve. The beverage valve is connected the dispenser body and is actively operable to control a flow of a base beverage into a flow path of the dispenser. The purge valve is selectively operable to control a flow of a purge substance into the flow path. A nozzle is configured to mix a flavoring from a flavoring nozzle with a base beverage from the beverage valve prior to dispensing a mixture of the flavoring and the base beverage from the nozzle.
1. A method of dispensing a flavored beverage to a consumer, wherein the flavored beverage comprises a mixture of a premixed base beverage and a flavoring, the method comprising:
receiving an order for the flavored beverage via a controller and a user input;
operating a beverage valve to dispense the premixed base beverage to a nozzle via a flow path;
operating a flavor source to begin dispense of the flavoring to the nozzle;
mixing the premixed base beverage and the flavoring in the nozzle to create the flavored beverage;
dispensing the flavored beverage to the consumer via the nozzle;
operating the flavor source to end the dispense of the flavoring to the nozzle while continuing the dispense of the premixed base beverage to the nozzle, and such that the premixed base beverage clears the flavoring from the nozzle; and
subsequently operating the beverage valve to end the dispense of the premixed base beverage to the nozzle;
operating a drain valve connected to the flow path between the beverage valve and the nozzle;
opening a purge valve to dispense a purge substance to the flow path, which purges the flow path of residual premixed base beverage, wherein the drain valve occludes the flow path and diverts the purge substance out of the flow path.
2. The method of claim 1 , further comprising, prior to dispensing the premixed base beverage to the nozzle, operating a flow valve to occlude the flow path and thereby cause the premixed base beverage to fill the flow path.
3. The method of claim 2 , further comprising, once the premixed base beverage fills the flow path, operating the flow valve to open the flow path and permit the dispense of the premixed base beverage to the nozzle.
4. The method of claim 1 , further comprising operating a different beverage valve to dispense a different mixed premixed base beverage via the nozzle.
5. The method of claim 1 , wherein the premix base beverage is beer.
6. A method of dispensing a flavored beverage to a consumer, wherein the flavored beverage comprises a mixture of a premixed base beverage and a flavoring, the method comprising:
receiving an order for the flavored beverage via a controller and a user input;
operating a flow valve to occlude a flow path in a dispenser for the premixed base beverage;
operating a beverage valve to dispense the premixed base beverage to the flow path until the premixed base beverage fills the flow path;
operating the flow valve to open the flow path and dispense the premixed base beverage to a nozzle via the flow path;
operating a flavor source to begin dispense of the flavoring to the nozzle;
mixing the premixed base beverage and the flavoring in the nozzle to create the flavored beverage;
dispensing the flavored beverage to the consumer via the nozzle; and
operating a drain valve connected to the flow path between the beverage valve and the nozzle;
opening a purge valve to dispense a purge substance to the flow path, which purges the flow path of residual premixed base beverage, wherein the drain valve occludes the flow path and diverts the purge substance out of the flow path.
7. The method according to claim 6 , further comprising operating the flavor source to end the dispense of the flavoring to the nozzle while continuing the dispense of the premixed base beverage to the nozzle, and such that the premixed base beverage clears the flavoring from the nozzle; and subsequently operating the beverage valve to end the dispense of the premixed base beverage to the nozzle.
8. The method of claim 6 , further comprising operating a different beverage valve to dispense a different mixed premixed base beverage via the nozzle.
9. The method of claim 6 , wherein the premix base beverage is beer.
