<p>A spout, system, and method for producing a foam from a pressurized mixture of a liquid containing gas bubbles, such as air bubbles. The spout consists of a spout enclosure defining the body of the spout, and which receives the pressurized mixture and conveys the foam out of the spout enclosure. The spout enclosure houses a plurality of screens disposed in series. The screens successively screen the pressurized mixture, and each screen is separated from a consecutive screen by a screen spacing. The successive screening of the pressurized mixture progressively transforms the gas bubbles in the liquid into foam bubbles of a smaller and generally uniform size, thereby producing the foam. The system uses a manifold having a plurality of intakes which introduce under pressure into a chamber gas, and a solute, solvent or liquid, thereby generating the pressurized mixture containing gas bubbles. This mixture is then conveyed out of the chamber via an outtake to the spout enclosure.</p> |
