Foam Control In Gas Charged Liquids Patents (Class 137/170.1)
  • Patent number: 8678247
    Abstract: A creamy foam beer dispensing system includes a coupler removably securable with a keg, a transportation tube, and a faucet having a handle coupled with a plunger communicating with the transportation tube. The handle is movable among a closed position, an open position, and a creamy foam position. In the closed position, the handle maintains the plunger squeezed against the transportation tube such that no beer flows from the faucet. In the open position, the handle lifts the plunger substantially, completely off the transportation tube such that beer flows smoothly from the faucet. In the creamy foam position, the handle lifts the plunger off the transportation tube a distance such that an aperture created in the transportation tube produces creamy foam flow from the faucet.

  • Patent number: 8671999
    Abstract: A method for removing foam with a foam retainer constructed with a hollow tubular body including a receiving end and a discharge end. A passage is formed within the hollow tubular body through which a liquid is adapted to flow. The discharge end of the hollow tubular body is adapted to snugly fit onto an open end of a container into which the liquid flows. As the container is filled with the liquid, the foam generated during the dispensing of the fluid rises back into the discharge end of the hollow tubular body. In the hollow tubular body, the foam is received and captivated therein such that when the hollow tubular body is removed, the foam may also be removed from the container.

  • Patent number: 8329764
    Abstract: A defoaming method capable of destroying foams generated when a container is filled with drink, or the like, efficiently at a high speed and destroying foams effectively even in the case of a container having a narrow mouth. Liquid surface (6) in a container (1) is irradiated with pulse-like light (2) and a pulse-like sound wave (8) is generated from an irradiated point (7) as a sound source. The pulse-like sound wave thus generated propagates from the sound source as a strong spherical wave to reach a bubble (9) and to destroy the bubble. It can also destroy a bubble located at a place remote from the optical path quickly, thus destroying bubbles efficiently at a high speed. Alternatively, pulse-like light is condensed at a gas portion above the liquid surface and the bubbles can be destroyed with a shock wave generated by breakdown phenomenon.

  • Patent number: 7784651
    Abstract: A tap for removing liquid from a container has a sleeve (10) made of plastic, in which a piston (12) is guided, and which sleeve has a passage opening (28) for the liquid. A hood that can be set onto the sleeve (10) in front of the passage opening (28), so that it covers the passage opening (28), serves as a foam throttle. The hood encloses a labyrinth channel (36), together with the sleeve, which channel is open at one end, towards the interior of the container, and ends in the passage opening (28) at the other end.

  • Publication number: 20100065130
    Abstract: A foam dispensing assembly comprises a dispensing head and a manifold assembly. The manifold assembly includes a purge portion for supplying a gas and a cleansing fluid to the dispensing head, a first supply portion for supplying a first fluid to the dispensing head and a second supply portion for supplying a second fluid to the dispensing head. Each of the purge portion, the first supply portion and the second supply portion include a plurality of check valves and flow control valves for controlling the flow of the first fluid, the second fluid, the gas and the cleansing fluid through the manifold assembly. Each of the first supply portion and the second supply portion include an integral flow control device for regulating a fluid flow rate to the dispensing head, and a thermometer for sensing the temperature of the first fluid and the second fluid respectively.

  • Patent number: 7306776
    Abstract: A method for processing flue gas scrubber material flows. The flue gas is scrubbed with a calcium-based absorbent containing washing fluid for absorbing sulphur oxides from the flue gases, and the formed gypsum slurry is directed from the flue gas scrubber to the separator. At the separating point of the separator, gypsum is separated from the washing fluid and the gypsum and washing fluid are taken out of the separator as separate material flows. From the flue gas scrubber the washing fluid is directed to a tank located before the separating point of the separator or after the separating point of the separator, in which tank foam is separated from the washing fluid as its own phase and taken out of the tank.

  • Patent number: 7244770
    Abstract: Methods suitable for selecting optimal defoamers for use in fermentation processes are described wherein the methods comprise: (a) determining an amount of each of two or more defoamers which provides a requisite dynamic surface tension of at most 50 mN/m at a particular frequency in a fermentation medium; and (b) selecting the defoamer which provides the requisite dynamic surface tension at the lowest amount. Methods for controlling foam by determining and adjusting dynamic surface tension are also described.

  • Patent number: 6478200
    Abstract: A beverage dispense device is designed to dispense a chilled carbonated beverage at a temperature close to the freezing point of the beverage without freezing and without excess break out of carbon dioxide. The beverage dispense device comprises a nozzle (19), a valve comprising a valve seat (13) and a closure member (16, 17), the valve being opened and closed by movement of the closure member (16, 17) out of and into contact with the valve seat (13) to allow or prevent flow of the beverage through the nozzle (19), and a flow regulator (18) between the valve seat (13) and the nozzle (19), the flow regulator (18) being adjustable to control flow rate through the nozzle (19) and being in the form of a core member (18) moveable in a flow passageway (15) downstream of the valve seat (13) and spaced from the valve seat, the core member (18) and the flow passageway (15) having matching tapering surfaces.
