Beverage extractor with controller
A system and method for dispensing beverage from a container, such as wine from a wine bottle. Dispensing may be automatically controlled based on a detected orientation of the container, e.g., dispensing may occur when a bottle is tilted as if to pour from the bottle and stopped when the bottle is oriented upright. Dispensing may be stopped when the container is rotated about its longitudinal axis even while in a pour orientation. A remaining amount of beverage in the container and/or an amount of pressurized gas used to drive dispensing may be detected and beverage dispensing controlled accordingly.
1. A container-mounted beverage dispensing system, comprising:
at least one conduit to deliver gas into a container holding a beverage and to receive beverage from the container for dispensing in a user's cup;
at least one valve to control gas flow into the container via the at least one conduit;
a gas cylinder fluidly coupled to the at least one conduit; and
a controller arranged to determine an amount of gas remaining in the gas cylinder based on an amount of time that the at least one valve is open to deliver gas into the at least one container, or based on a total volume of beverage dispensed using the gas cylinder.
2. The system of claim 1 , further comprising a pressure sensor to detect a pressure indicative of gas pressure in the container, and wherein the controller is arranged to determine an amount of gas remaining in the gas cylinder based on an amount of time that the at least one valve is open to deliver gas into the at least one container and a gas pressure in the container.
3. The system of claim 1 , wherein the at least one valve includes a gas valve arranged to control flow of gas between the gas cylinder and the at least one conduit, and a beverage valve arranged to control flow of beverage between the at least one conduit and a beverage outlet.
4. The system of claim 1 , wherein the at least one conduit includes a single conduit to deliver gas into the container and receive beverage from the container.
5. The system of claim 4 , wherein the single conduit is part of a needle arranged to be inserted through a cork in an opening of the container.
6. The system of claim 1 , wherein the at least one conduit includes a first conduit to deliver gas into the container and a second conduit to receive beverage from the container.
7. The system of claim 6 , wherein the first and second conduits are part of a needle arranged to be inserted through a cork in an opening of the container.
8. The system of claim 1 , wherein the at least one valve includes a beverage control valve arranged to control flow of beverage from the at least one conduit to a beverage outlet.
9. The system of claim 1 , further comprising:
a container orientation sensor to detect whether the container is in a pour orientation or a no-pour orientation; and
wherein the controller is arranged to control the at least one valve to allow gas or beverage flow in the at least one conduit when the container is in a pour orientation and to control the at least one valve to prohibit gas or beverage flow when the container is in a no-pour orientation.
10. The system of claim 9 , wherein the orientation sensor is arranged to detect a pour condition when a bottom of the container is above an opening of the container.
11. The system of claim 9 , wherein the orientation sensor is arranged to detect a pour condition when a longitudinal axis of the container is rotated about a horizontal axis by at least 90 degrees.
12. The system of claim 9 , wherein the controller is arranged to open the at least one valve to allow pressurized gas to flow into the container when the container is in a pour orientation and to close the at least one valve to prohibit pressurized gas to flow into the container when the container is in a no-pour orientation.
13. The system of claim 12 , wherein the at least one conduit includes a single conduit, and the controller is arranged to alternate between opening the at least one valve to allow pressurized gas to flow into the container via the single conduit and closing the at least one valve to prohibit pressurized gas to flow into the container and allow beverage to flow from the container via the single conduit when the container is in a pour orientation.
14. The system of claim 9 , wherein the controller is arranged to open the at least one valve to allow beverage to flow from the at least one conduit to a beverage outlet when the container is in a pour orientation and to close the at least one valve to prohibit beverage to flow from the at least one conduit to the beverage outlet when the container is in a no-pour orientation.
15. The system of claim 1 , wherein the controller is arranged to control the at least one valve to dispense a defined amount of beverage from the container.
16. The system of claim 1 , wherein the controller is arranged to control the at least one valve in two modes including a first mode for dispensing beverage at a maximized dispensing speed and a second mode for dispensing beverage with minimized pressurized gas usage.
17. The system of claim 1 , wherein the controller is arranged to determine the amount of gas remaining in the gas cylinder based on an amount of time that the at least one valve is open to deliver gas into the at least one container.
18. The system of claim 1 , wherein the controller is arranged to determine an amount of gas remaining in the gas cylinder based on a total volume of beverage dispensed using the gas cylinder.
19. The system of claim 1 , wherein the controller is arranged to alert a user that the gas cylinder needs replacement.
20. The system of claim 1 , wherein the controller is arranged to refuse to perform a dispensing operation where the gas cylinder does not have sufficient gas to perform the dispensing operation.
