The invention provides containers for pressuring an aqueous liquid with a gas to increase the concentration of the gas in the aqueous liquid. The container employs one or more moveable sections to reduce the accessible volume of the container, e.g., allowing gases such as H2 to become supersaturated within an aqueous liquid.

A device (1) for filling a container (2) with a carbonated liquid, containing at least: an upper part (3) and a lower part (4) having a container port (5) for securing the container (2) to the device (1), wherein the lower part (4) can be displaced within limits relative to the upper part (3) between a closed position (23) and a venting position (6), and wherein the container (2) can displace the lower part (4) to the closed position (23) when the container (2) is secured to the container port (5), and the container (2) can displace the lower part (4) to the venting position (6) when the container (2) is released from the container port (5), such that a high pressure in the container (2) can be reduced in the venting position (6) of the lower part (4) prior to releasing the container (2) from the container port (5).

The present invention relates to a method for extracting coffee using supercritical nanobubbles, and coffee extracted thereby, and specifically, to a method for extracting coffee capable of extracting coffee by bringing nanobubbles having a high pressure corresponding to a supercritical state into contact with coffee beans, thereby improving an extraction speed of coffee and increasing a concentration of the coffee, and coffee extracted thereby. A method for extracting coffee using supercritical nanobubbles of the present invention includes a bubble water generation step of obtaining bubble water in which nano bubbles are formed, and an extraction step of extracting liquid coffee by applying bubble water to ground coffee beans, in which the bubbles have a diameter of 10 to 200 nm and an internal pressure of 50 to 150 atm.

A beverage carbonator includes a carbonation chamber having a carbonation source inlet, a fluid inlet, a gas outlet, and a carbonation source carrier. The carbonation source carrier is positioned to receive carbonation source deposited into the carbonation chamber through the carbonation source inlet. The carbonation source carrier and fluid inlet arranged to isolate carbonation source carried on the carbonation source carrier from liquid collected in the carbonation chamber through the fluid inlet until a predetermined volume of liquid is admitted into the carbonation chamber.

A bottle, in particular a reusable and refillable bottle for CO.sub.2-containing drinks, which can be carbonated and stored in the bottle. A bottle with better usage properties is to be achieved. The bottle includes a closable liquid container with an adapter which is attached or flanged to the base of the liquid container and which contains a CO.sub.2 tank.

A system for mineralizing distilled water includes a splitter for splitting distilled water into primary and secondary portions; first and second conduits for conveying the primary and second portions, respectively; first and second columns comprising including first and second mineral matrices connected to the first and second conduits, respectively, to generate first and second mineralizing concentrate solutions; first and second mixing modules for combining a predefined amount of the mineralizing concentrate solutions with the primary portion of distilled water to form a mineralized water mixture; and a dispensing module for dispensing the mineralizing water mixture. A carbonator is also connected to the secondary conduit for dissolving carbon dioxide in the secondary portion of distilled water upstream of the first and second columns.

A control method of a carbonated water machine and a carbonated water machine are provided. The carbonated water machine includes a mixer, a liquid supply assembly, and a gas supply assembly. A mixing cavity is formed in the mixer, and the mixer is provided with a gas-liquid inlet and an outlet connected to the mixing cavity, a liquid outlet of the liquid supply assembly and a gas outlet of the gas supply assembly are both connected to the gas-liquid inlet, the control method includes: receiving a carbonated water production instruction; and turning on the liquid supply assembly to inject liquid into the mixing cavity, and turning on the gas supply assembly to inject carbon dioxide into the mixing cavity, so that the liquid and the carbon dioxide are mixed in the mixing cavity to form carbonated water. The present application can improve a convenience of carbonated water production.

A nanobubble manufacturing system comprising: a gas supply unit, supplying gas; a mixing device, mixing the gas with liquid into a first solution; and an ultrasonic oscillator, vibrating the first solution to produce a second solution having nanobubbles.

The invention provides containers for pressuring an aqueous liquid FIG. 1 with a gas to increase the concentration of the gas in the aqueous liquid.

Embodiments disclosed herein provide systems and methods for water aeration in a tank or other body of water that a specialized coupling assembly and flexible hose connectors rather than the commonly used rigid connector elements. The coupling assembly and flexible hose connectors utilized in the aeration grid system provide a more cost effective and flexible system that allows almost limitless configurations of the diffuser elements, depending on the intended application. Further, the coupling assembly and flexible hose connectors enable use with a wide variety of air supply pipe diameters without the necessity of providing a fitting or adapter for each pipe opening. The capability of the aeration system to be readily adapted to different sizes of treatment tanks or ponds, for example, allows the installation and use of a more flexible, prefabricated, or modular, and ultimately more efficient aeration system.
