A device for generating bubbles, comprising a porous material having at least one hydrophilic surface (1), arranged such that a liquid (7) in which the bubbles (6) are intended to be formed may contact the hydrophilic surface (1) and at least one hydrophobic surface (2), arranged such that a gas (5) used to generate the bubbles (6) may flow past the hydrophobic surface (2) before it flows past the hydrophilic surface (1). The device may be used for creating fine bubbles in numerous applications, such as wastewater treatment, plant cultivation, aquafarming, aeration systems, bioreactors, fermeters, oil extraction or fuel cells.

A carbonated water dispenser comprises a carbonator with a water inlet and a carbonated water outlet. A backflow preventer module is fluidically coupled to the water inlet and comprises a check valve and a thermal mass flow meter. The thermal mass flow meter is configured to communicate a first signal based on a measured amount of heat transferred from a heater to a temperature sensor by a flow of a fluid through the backflow preventer module. A shut-off valve is fluidically coupled between the carbonated water outlet and a nozzle. The shut-off valve is configured to allow or prevent fluid flow from the carbonated water outlet to the nozzle base on a control signal. A controller is configured to detect a backflow condition based on the first signal and generate the control signal to configure the shut-off valve to prevent dispensing carbonated water upon detection of the backflow condition.

A device for synthesizing carbonated water includes: a device shell, in which a stirring chamber is defined; a rotation shaft, which is accommodated in the stirring chamber; a blade structure, which is accommodated in the stirring chamber and rotatable around the rotation shaft; sidewall ribs, which are distributed in the stirring chamber and arranged on a sidewall of the device shell, each sidewall rib comprising one or more collision interfaces; an input unit, which is arranged on the device shell, positioned below the blade structure, communicated with the stirring chamber, and operable to receive water and carbon dioxide; and an output unit, which is arranged on the device shell, positioned above the blade structure, communicated with the stirring chamber, and operable to deliver carbonated water with a predetermined concentration.

The apparatus includes a reservoir (2), a liquid source (1), a carbon dioxide source (12), a non-return valve (8), a carbonating vessel (7) to receive liquid from the reservoir (2) via the non-return valve (8), a gas inlet (15) to receive carbon dioxide from the carbon dioxide source (12), and a dip tube (16) to withdraw carbonated liquid from the carbonating vessel. A pressure relief valve (20) vents gas from the carbonating vessel (7), and a dispense valve (18) controls the supply of carbonated liquid from the dip tube (16) to a dispense outlet (17). A charge control valve (14) controls the supply of carbon dioxide to the carbonating vessel (7). The apparatus has the following modes of operation-charge: the dispense valve (18) is held closed while the charge control valve (14) is opened to admit a charge of carbon dioxide into the carbonating vessel (7); dispense/refill: the dispense valve (18) is opened to dispense carbonated liquid while liquid flows into the carbonating vessel from the reservoir (2) via the non-return valve (8). The carbonated beverage can

A system and method for dosing SO.sub.2 into wine barrels is achieved with a device including a compressed gas cylinder containing compressed liquefied SO.sub.2 under its own vapor pressure, a dosing wand fluidly connected to the cylinder via a hose that is adapted and configured to allow a flow of gaseous SO.sub.2 from the source to the dosing wand. The dosing wand includes a hollow needle dispensing nozzle and a SO.sub.2 batch flow controller in fluid communication between the hose and the hollow needle. The hollow needle dispensing nozzle is adapted and configured to pierce through a bung opening of a wine barrel and has at least one aperture at a terminal end thereof to allow gaseous SO.sub.2 to be dispensed into an interior of the wine barrel.

An aerator and an associated method and system are provided. The aerator includes an elongate body having a central bore that extends between proximal and distal ends of the body, and a plurality of channels formed in an outer surface of the body, the plurality of channels extending between the proximal and distal ends, and including at least two bends along their lengths. The bends in the channels help to provide a smoother flow of liquids passing through the aerator.

A system and method of controlling a concentration of one or more gases dissolved in a beverage is shown. The system includes a saturation tank having a gas head space, a brite tank, and a beverage supply system to pass the beverage between the saturation tank and the brite tank. A beverage supersaturated with the gas from the head space is formed in the saturation tank. The supersaturated beverage is passed from the saturation tank to the brite tank. Once the amount of gas added to the beverage exceeds saturation, some of the gas escapes from solution from the beverage and the pressure in the brite tank increases. Once the pressure within the brite tank reaches a pre-defined pressure, a pump supplying the beverage to the saturation tank is shut-off and the inlet and outlet valves of the brite tank are closed.

A gas-saturated liquid generator having a vessel of the generator, a hollow bell in its upside down position located with a tube for gas supply, and a mixer situated in the area for saturated liquid covered by the bell is disclosed. The entire bell is submerged below the surface of the saturated liquid. On a shaft projecting from a driving equipment, the mixer provided with a foaming spring is situated. The mixer provided with a magnetic carrier seated rotatably on the protrusion formed by a bulge in the bottom part of the generator vessel may be used. The preferred bell forms are dome-shaped, cylindrical or conical.

A carbonation system for a beverage appliance or machine that can include a liquid chamber and a carbonation chamber separated from the liquid chamber by a wall of the carbonation chamber is disclosed herein. In some implementations, the liquid chamber is defined by a liquid tank (e.g., a water tank), and the carbonation chamber is defined by a carbonation tank. The carbonation system can move liquid (e.g., water) from the liquid chamber to the carbonation chamber and introduce carbonating gas (e.g., carbon dioxide) into the carbonation chamber to create a carbonated liquid (e.g., a carbon dioxide water dissolution, such as carbonated water, sparkling water, or seltzer).
