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.

This invention is a method by which four separate variables are manipulated in a manner that creates a process to force nitrogen into non-alcoholic carbonated beverages in a pressure rated vessel that is equipped to introduce the gas through the bottom of the pressure rated vessel. The four separate elements in this invention are Temperature, Pressure, Time, and Agitation. The purpose of this invention is to achieve a total of 30% total gas absorption of Carbon Dioxide and 70% total gas absorption of Nitrogen into Non-Alcoholic beverages including but not limited to Soda, Tea, Energy Drinks, Horchata, Fruit Juices, Water, Mineral Water, Fruit Juice Cocktails, Cocktail Mixers, Switchel, Lemonade, Limeade, vitamin drinks, orangeade, hang over remedies, and sports drinks, excluding all coffee and flavored coffee drinks.

A system for gas impregnation of a liquid includes a container for holding a product ingredient, a first still liquid conduit for conveying a still product including the ingredient, a gas cylinder providing a gas conduit with a compressed gas such as Nitrogen. The system includes two or more pressure chambers each having a corresponding liquid fill valve to control the flow of a still product filling the pressure chamber, and a gas diffuser for diffusing the compressed gas into the still product to produce a gas infused product. A multi-way valve in fluid communication with each of the pressure chambers directs the gas infused product from a selected one of the pressure chambers to a first charged product conduit for supplying a charged liquid dispenser, and blocks fluid from flowing from other, non-selected, ones of the pressure chambers. A method for using the subject system is also provided.

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 liquid dispenser comprise a nozzle comprising an inlet in fluid communication with an outlet to form a flow path, a thermistor in fluid communication with the inlet, an actuator rod comprising a gasket rod tip viton, at least one centering pin to center the actuator rod in at least a portion of the flow path, a flowmeter in fluid communication with the inlet, a double acting pneumatic cylinder comprising a first pneumatic inlet and a second pneumatic inlet operatively connected to the actuator rod, and a switch lever operatively coupled to a micro switch, wherein the nozzle opens when gas enters the first pneumatic inlet when the switch lever is activated by pressing on the micro switch and closes when gas enters the second pneumatic inlet when the switch lever is deactivated. Portable and non-portable liquid dispensing systems comprising the liquid dispenser are also described.

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.

A portable apparatus for mixing fluids comprising is provided, and has a housing, inlets for receiving a plurality of fluids at the housing, and a fluid mixer for receiving the fluids from the housing and mixing them. The fluid mixer outputs at least one fluid blend. A fluid blend selector then receives fluids from the inlets and at least one blend from the fluid mixer and outputs a selected fluid, where the selected fluid is one of the fluids from the inlets or one of the at least one fluid blends.

A system and method to prepare and dispense a N.sub.2 or N.sub.2/CO.sub.2 gas infused chilled beverage is provided. The beverage may be any non-carbonated liquid and in one embodiment the beverage is coffee. The dispensed N.sub.2 or N.sub.2/CO.sub.2 gas infused chilled coffee has a unique appearance and enhanced flavor and aroma. The system may be provided as a self-contained unit.

A system and method for dispensing sparkling and other pressurized beverages from a container. Sparkling wine and other beverages may be dispensed without removing a cork or other closure. One or more needles may be inserted through the closure and sparkling beverage dispensed through the one or more needles. The one or more needles may be inserted at an angle to the vertical or axis of the bottle opening in which the closure is positioned, e.g., to avoid contact with a metal retainer on the closure. Dispensed beverage may be directed to a pressurized reservoir to help maintain or recover carbonation prior to dispensing.

A cap for engagement with a beverage container allows an extractor needle or other conduit to pass through a portion of the cap such that beverage can be removed from the container without removing the cap. The cap may include a septum that is radially and/or axially compressed and a barrier layer arranged to engage with the container to form a seal.
