    摘要： 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.

    摘要： A fine bubble generator may include an inlet, an outlet, a first fine bubble generation portion including a first flow path, and a second fine bubble generation portion including a second flow path. The first flow path may include a diameter-reducing flow path and a diameter-increasing flow path. The second flow path may include a guide flow path and a collision flow path disposed downstream of the guide flow path. A first bearing and a first impeller rotatably attached to the first bearing may be disposed on the collision flow path. The first impeller may include a disc disposed at a position at which the gas-dissolved water collides with the disc; a first rotation shaft disposed on a downstream surface of the disc and rotatably attached to the first bearing; and one or more first vanes disposed on an upstream surface of the disc.

    摘要： A passive gas exchange transfer apparatus for exchanging carbon dioxide from a flue gas to a water supply is disclosed. The apparatus includes several upper rods and several lower rods to hold a membrane in place. The membrane provides increased surface area for the gas and the water to meet. The upper rods may be the source of the water supply, and the lower rods may be the source of the gas. The upper rods may disperse the water onto one side of the membrane, and the lower rods may disperse the gas onto the other side. The two may therefore meet at the surface created by the membrane as gravity draws the water downward, and convection draws the gas upward.
