Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

A beverage aerator includes a housing, a pump-motor assembly, an uptake tube, and a spray nozzle. The housing is sized to removably seat on a neck of a decanting vessel. The pump-motor assembly is positioned within the housing, and has a pump inlet and a pump outlet. The uptake tube is fluidly coupled to the pump inlet upstream of the pump inlet. The uptake tube has a tube inlet end located below the housing. The spray nozzle is fluidly coupled to the pump outlet downstream of the pump outlet. The spray nozzle is located below the pump-motor assembly and oriented to have a laterally-outward discharge direction.

A decanter for bottled wine includes a main body having a first end, a second end, a bottle mouth insertion portion, an accommodating chamber and a wine guide portion, an outer cylinder covering the main body and a rotary shaft. At least one retaining ring is provided on an outer wall of the bottle mouth insertion portion. A bottom of the accommodating chamber has a plurality of equally spaced first through, protruding posts each having a second through hole, and an inner shaft seat. An inner end of the rotary shaft is pivotally connected to the inner shaft seat. The wine guide portion is disposed inside the second end of the main body and located at an outer end of the accommodating chamber. The wine guide portion includes an outer shaft seat for pivotally connecting an outer end of the rotary shaft and a plurality of wine guide holes.

A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.

A substrate processing system includes a chemical liquid preparation unit preparing a chemical liquid to be supplied to a substrate and a processing unit which supplies the chemical liquid, prepared by the chemical liquid preparation unit, to the substrate. The chemical liquid preparation unit supplies an oxygen-containing gas, containing oxygen gas, to a TMAH-containing chemical liquid, containing TMAH (tetramethylammonium hydroxide), to make the oxygen-containing gas dissolve in the TMAH-containing chemical liquid.

A liquid dispensing device and system to dispense, or aerate and dispense a liquid such as wine through a spout. The dispensing device having multiple air ports and aeration chambers to form multiple aerating segments during the pour process. The dispensing device having a handle to increase grasping of a liquid container and preventing accidental separation of the device and a container.

A decanter includes a first body and a second body mounted on the first body. The first body is provided with a bottle insert, a curved wine channel and a wine outlet. The curved wine channel has an opening and is provided with a plurality of stepped portions. The second body covers and closes the first body, and a mixing cavity is defined between the second body and the curved wine channel. The second body is provided with a plurality of stop plates. The stop plates and the stepped portions form a tortuous passage in the mixing cavity. In practice, when the wine in the wine bottle enters the mixing cavity, the wine hits and is stirred by the stepped portions and the stop plates to enhance the mixing effect of the wine and the air.

A decanting vessel has an internal pump for recirculating a beverage such as wine and aerating it within the decanter.

One embodiment provides a wine aerating device, including: a funnel-shaped container comprising a bottom that is provided with an outlet aperture having a predetermined size, wherein said funnel-shaped container is at least partially filled with a multitude of substantially spherical elements for breaking up and diverting a flow of wine streaming from the top to the bottom of said funnel-shaped container, each of said substantially spherical elements having a size significantly smaller than the size of said outlet aperture, and wherein a non-spherical element having a size greater than the size of said outlet aperture is placed upon said outlet aperture to partially block it, thereby preventing said spherical or nearly-spherical elements to pass through said outlet aperture while allowing the passage of wine through said outlet aperture and increasing the wine's turbulent motion and oxigenation while coming out of said funnel-shaped container. Other aspects are described and claimed.
