A mixing valve is described for a dispensing device for dispensing a cooled beverage mixed with a gas, comprising: a first inlet which can be fluidically connected to a first source of gas and can be supplied with the gas; a second inlet which can be connected to a second source of the beverage without gas and can be supplied with the beverage not mixed with the gas; an outlet which can be connected to a first dispensing mouth for dispensing the beverage mixed with the gas; the dispensing mouth is available in a closed or open configuration to prevent or allow dispensing of the beverage mixed with said gas; a chamber interposed between the first and the second inlet on one side and the outlet on the other side and adapted to allow mixing of the gas and non-mixed beverage, thus forming the beverage mixed with the gas; and regulation means, configured to allow, when the first dispensing mouth is arranged in the open configuration, the passage, respectively, of a first flow value of gas between the first inlet and the outlet and a second flow value of non-mixed beverage between the second inlet and the outlet.

A beverage dispensing apparatus may include a beverage dispenser and associated stopper. The stopper may be used to replace a cork, cap or other closure of a beverage container, such as a wine bottle. A needle of the beverage dispenser may be inserted through a passageway of the stopper so that pressurized gas can be introduced into the container to force beverage liquid to exit the container via the needle. The stopper may suitably seal the container after dispensing is complete, e.g., to resist exposing the beverage to oxygen.

Beverages such as beer and soda which contain carbon dioxide or other gases may degrade in quality when subjected to atmospheric pressure, oxygen, and/or light. It may be desirable to store such beverages in containers which prevent exposure to these conditions. An aluminum can is one such container but is associated with the problem of resealing the can after breaking the seal. The described utilities provide for resealing, pressurizing, and/or dispensing from an aluminum can or similar beverage container.

A gas liquid absorption device (GLAD), featuring a gas inlet manifold, a liquid inlet manifold and a gas/liquid mixing foamer. The gas inlet manifold has a gas inlet configured to receive and provide an inlet gas, and also has a gas foamer cavity formed therein and coupled fluidically to the gas inlet to receive the inlet gas. The liquid inlet manifold has a liquid inlet configured to receive and provide a non-infused liquid, and also has a liquid foamer cavity formed therein and coupled fluidically to the liquid inlet to receive the non-infused liquid. The gas/liquid mixing foamer is configured between the gas inlet manifold and the liquid inlet manifold and arranged in the gas foamer cavity and the liquid foamer cavity. The gas/liquid mixing foamer has a gas foamer wall configured to form a gas receiving foamer chamber that is fluidically coupled to the gas foamer cavity. The gas foamer wall has gas provisioning holes formed therein to provide dispersed inlet gas from the gas receiving foamer chamber. The gas/liquid mixing foamer has a liquid foamer wall configured to form a liquid receiving foamer chamber that is fluidically coupled to the liquid foamer cavity. The liquid foamer wall having liquid provisioning holes formed therein to provide dispersed non-infused liquid from the liquid receiving foamer chamber. The mixing chamber is configured to receive the dispersed inlet gas and the dispersed non-infused liquid, infuse the dispersed inlet gas and the dispersed non-infused liquid, and provide a foamed gas/liquid mixture from the mixing chamber.

A system and method to supply nitrogen gas is provided. Ambient air is compressed and stored in a storage receiver and then nitrogen is separated from the compressed air in a nitrogen membrane separation unit. The separated nitrogen is stored in a nitrogen storage tank under pressure and released through a pressure control valve. The system is confined to a small footprint and is useful as a nitrogen source where conventional compressed nitrogen tanks are a safety or space issue. Systems to prepare nitrogen infused beverages are also provided.

A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.

A beverage dispensing machine for dispensing a mixed beverage has a first inlet configured to receive a concentrate; a second inlet configured to receive a base fluid; a gas inlet configured to receive a gas; a gas injection device configured to pulsate the gas into the concentrate such that the gas agitates the concentrate and is injected into the concentrate to form a gas-injected concentrate; and a dispensing valve configured to dispense the base fluid and the gas-injected concentrate.

Examples disclosed herein relate to a dispensing device including a product unit with a pressure which transmits one or more products to an infuser, a water source with one or more CFValves that transmits water to the infuser, a gas source which transmits one or more gases to the infuser, and a dispensing area which dispenses a mixture generated via the infuser from a product unit input, a water source input, and a gas source input.

Devices and methods for dispensing beverage from a container, such as a wine bottle, using a dispensing device. The device may automatically purge at least one conduit used to deliver gas to a beverage container or to carry beverage from the beverage container in response to detecting that a dispensing operation is about to begin, or in response to detecting that a dispensing operation is complete. Visual or other displays may be provided to the user to indicate that the device is ready for use in dispensing, that a conduit is in fluid communication with the container interior and/or that the device is controlling components to dispense beverage.
