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.

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

A bubble splitter, which is arranged for splitting gas bubbles in a bubbled liquid in at least a micro size, includes a splitting housing, a plurality of first splitting discs, and a plurality of second splitting discs. The first and second splitting discs are alternating with each other to be spacedly supported within the splitting housing, wherein a plurality of peripheral passages are formed at peripheral portions of the first splitting discs respectively and a plurality of central passages are formed at center portions of the second splitting discs respectively. The bubbled liquid is detoured to radially and outwardly move from the central passage to the peripheral passage and is detoured to radially and inwardly move from the peripheral passage to the central passage so as to split the gas bubbles in the bubbled liquid in at least a micro size.

A method is provided for producing fine-bubble water by resonance foaming and vacuum cavitation, and a device for manufacturing each of ultra-fine-bubble water of hydrogen gas having a reducing radical function, ultra-fine-bubble water of air and oxygen gas having an oxidizing radical function, ozone ultra-fine-bubble water having a sterilization function enabled by ozone, and fine-bubble water of nitrogen/carbon dioxide gas for increasing the ability to preserve the freshness of raw agricultural products, livestock products, and marine products.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

According to one or exemplary embodiments, there is provided a Gas Infusion Module that is a compact, inexpensive, adjustable, and easy to clean apparatus for infusing a beverage, such as coffee or tea, with a gas. The Gas Infusion Module controls the mixing of the gas with a liquid beverage in a homogenization element. To achieve an enhanced homogenization of gas and liquid, first the Gas Infusion Module regulates the pressure of gas that will enter the homogenization element and mix with the liquid. Additionally, the liquid and gas mixture passes through an outlet check valve which forces greater homogenization of the aerated fluid before it is dispensed for consumption.

A carbon dioxide and nitrogen infused wine product includes wine infused with both carbon dioxide and nitrogen. A ratio of carbon dioxide to nitrogen in said wine can be in a range of 80%CO.sub.2/20%N.sub.2-60%CO.sub.2/40%N.sub.2.

A method for manufacturing beverage or other liquid containing bubbles uses a system for manufacturing bubble-containing liquid that includes: a bubble generating unit that generates fine bubbles in a liquid; a bubble collapsing unit that is connected to the bubble generating unit to collapse the fine bubbles contained in the bubble-containing liquid supplied from the bubble generating unit by making the bubble-containing liquid pass through the bubble collapsing unit and irradiating the bubble-containing liquid with ultrasonic wave; and a storage unit that is connected to the bubble collapsing unit to store the bubble-containing liquid supplied from the bubble collapsing unit. The method includes: a bubble generating step of generating the fine bubbles in the liquid by the bubble generating unit; a bubble collapsing step of generating superfine bubbles by forming an ultrasonic field by the bubble collapsing unit to collapse the fine bubbles contained in the liquid; and a storage step of storing the bubble-containing liquid containing the superfine bubbles by the storage unit. Consequently, beverage or other liquid containing the superfine bubbles can be manufactured.
