A beverage dispensing system includes an infusion unit and a dispensing station. The infusion unit is to mix a liquid beverage product and a gas to produce a gas-infused liquid beverage product. The infusion unit includes a first infusion unit inlet to receive the liquid beverage product, a second infusion unit inlet to receive the gas, and a first infusion unit outlet to output the gas-infused liquid beverage product. The dispensing station includes a first valve, coupled to the first outlet of the infusion unit, to receive and dispense the gas-infused liquid beverage product. The dispensing station further includes a second valve to receive and dispense the liquid beverage product.

In a method for infusing a gas from a gas source into a liquid beverage, liquid beverage is driven from a beverage container into a liquid inlet port of a venturi mixing device. Nitrogen is infused into the liquid beverage by driving nitrogen through a gas inlet port of the venturi mixing device, thereby delivering nitrogen-infused liquid beverage to a discharge port of the venturi mixing device. The nitrogen-infused liquid beverage is poured from the discharge port through a faucet.

Disclosed herein are techniques and methods for dispersing a volume of gas in a beverage contained in an unpressurized container.

A spiral mixing chamber for dissolving a gas into a liquid, features a new and unique combination of a cap and a mixing plate. The cap may include a gas injector configured to receive gas. The mixing plate may include: a liquid inlet configured to receive liquid, a mixture outlet configured to provide a mixture of the gas and liquid from the spiral mixing chamber, and a flow path configured as a spiral geometry having a spiral that winds in a continuous and gradual curve around a central point from the liquid inlet to the mixture outlet, the flow path having flow path obstructions configured to cause disturbances in the flow which generates turbulent vortices that work to break apart bubbles in the mixture flowing through the spiral mixing chamber or device.

A chemical liquid preparation method of preparing a TMAH-containing chemical liquid, including, a correspondence relationship preparing step of preparing a correspondence relationship between a supply flow rate ratio between an oxygen-containing gas and an inert-gas-containing gas and a convergent dissolved oxygen concentration in the TMAH-containing chemical liquid that is converged to when the oxygen-containing gas and the inert-gas-containing gas are supplied into the TMAH-containing chemical liquid; a concentration setting step of setting a target dissolved oxygen concentration in the TMAH-containing chemical liquid; a supply-flow-rate-ratio acquiring step of acquiring the supply flow rate ratio between the oxygen-containing gas and the inert-gas-containing gas corresponding to the target dissolved oxygen concentration in accordance with the correspondence relationship prepared in the correspondence relationship preparing step; and a gas supplying step of supplying the oxygen-containing gas and the inert-gas-containing gas with the supply flow rate ratio acquired in the supply-flow-rate-ratio acquiring step.

Implementations of fluid modifying and dispensing systems may include a fluid modifying assembly having a fluid modification unit including a gas dosing unit configured to infuse a fluid with a gas, a filter configured to filter the fluid, and a pH regulator configured to modify a pH of the fluid. The fluid modifying assembly may include a temperature regulation system coupled to the fluid modification unit. The fluid modifying assembly may also include a dosing system coupled to the fluid modification unit. The dosing system may be configured to add one or more supplements to the fluid. The fluid modifying and dispensing system may include a fluid dispensing assembly having a faucet coupled to the fluid modifying assembly and a vessel having a lid and a base. The base of the vessel may be configured to couple directly to the faucet to fill the vessel with the fluid.

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 method according to an embodiment may be used to make a carbonated protein beverage composition for large quantity mass production purposes. The method includes flowing a liquid protein concentrate and water, and mixing them to form a beverage composition pre-mix. The temperature of the pre-mix is sensed, and the water temperature of the water prior to mixing with the flowing protein concentrate is controlled to maintain a substantially constant temperature of the beverage composition pre-mix. Carbonation is added to the temperature controlled pre-mix to form the carbonated protein beverage composition, which is then containerized.

Systems and methods are described for dissolving ammonia gas in deionized water. The system includes a deionized water source and a gas mixing device including a first inlet for receiving ammonia gas, a second inlet for receiving a transfer gas, and a mixed gas outlet for outputting a gas mixture comprising the ammonia gas and the transfer gas. The system includes a contactor that receives the deionized water and the gas mixture and generates deionized water having ammonia gas dissolved therein. The system includes a sensor in fluid communication with at least one inlet of the contactor for measuring a flow rate of the deionized water, and a controller in communication with the sensor. The controller sets a flow rate of the ammonia gas based on the flow rate of the deionized water measured by the sensor, and a predetermined conductivity set point.

In a device for infusing a gas from a gas source into a liquid beverage, a beverage container defines an interior for holding the liquid beverage therein. A venturi mixing device has a liquid inlet port in fluid communication with the beverage container, a gas inlet port in fluid communication with the gas source and a discharge port. The venturi mixing device is configured to infuse the gas received from the gas source into liquid beverage received from the beverage container. A faucet is in fluid communication with the discharge port of the venturi mixing device and is configured to dispense the liquid beverage infused with the gas.
