A beverage supply apparatus 100 includes milk tank 3, milk flow path L3, pump 7 for delivering a beverage, air flow path L6, pump 9 for supplying air configured to be capable of changing the discharge flow rate, release path L7 for discharging air flowing through air flow path L6 to the outside, on-off valve V7, first throttle part 16, and second throttle part 17. One end of release path L7 is connected to release point Z8 in air flow path L6, and the other end is open to the outside. On-off valve V7 is disposed in a flow path extending between release point Z8 and pump 9 in air flow path L6, and opens and closes this flow path. Throttle part 16 is disposed in a flow path extending downstream of release point Z8 in air flow path L6, and throttle part 17 is disposed in release path L7.

Provided is a foam discharger including: a mixing portion for mixing a liquid agent and a gas to foam the liquid agent; a discharge opening for discharging the foamed liquid agent; and a flow path in communication with the discharge opening, and for supplying the foamed liquid agent from the mixing portion to the discharge opening. The discharge opening is provided with a first porous member. On an upstream side of the first porous member, a cross-sectional area of the flow path on a cross section orthogonal to a supply direction in which the foamed liquid agent is to be supplied increases along the supply direction. The cross-sectional area of the flow path at the discharge opening is at least 1.2 times the minimum cross-sectional area of the flow path.

Foamable formulations of agriculturally active ingredients are provided, as well as methods for using them. The formulations allow improved delivery active ingredients by the ability to deliver high amounts of active ingredient with a low volume of formulation used.

A mixing apparatus is described. The mixing apparatus has a first port for receiving milk, a second port for receiving steam, and a mixing chamber for mixing the milk, the steam, and air. A channel arrangement connects the first port and the second port, and defines an air intake channel which leads to a frothing section. The mixing apparatus is designed such that, in use, the frothing section fills sufficiently with steamed milk that has a direct path from the second port to the mixing chamber is interrupted by the steamed milk. This provides a noise reduction during use of the mixing apparatus. A flow reducing means, such as a barrier, may be used for this purpose.

A method of manufacturing a self-expanding fire-fighting foam solution is disclosed. Here, the method can include purging air from a container, wherein the purging is performed via flowing an inert gas into the container, such that substantially inert environment is created within the container. In addition, the method can further include dispensing or filling a pre-determined amount of foam concentrate into a container, dispensing or filling a pre-determined amount of water into the container, and mixing the foam concentrate and water within the container, wherein the mixed foam and water within the inert container provide the self-expanding fire-fighting foam solution and having a pH ranging from about 6.8 to 7.8 moles per liter.

A machine produces foam-in-bag from foam precursors mixed within the bag. The machine comprises a base and a shell. The base and shell are moveable relative each other between a base/shell disengaged position and a base/shell engaged position. In the base/shell engaged position, the base and shell divide the bag so that a mixing chamber is isolated from the remainder portion of the bag. First and second nozzles inject foam precursors into the mixing chamber. A mixer engages the mixing chamber to provide mixing energy to facilitate the foam reaction.

An apparatus for continuously generating and controlling the density of foam has a fluid in-flow manifold in communication with a source of liquid and comprising a pressure sensor. A plurality of branch lines are in fluid communication with the in-flow manifold a foam out-flow manifold. Each branch line has a flow control valve, a Venturi tube and in fluid communication with a throat of each Venturi tube an air induction control valve. The foam out-flow manifold has a pressure sensor. At least one in-flow control valve is disposed between the source and the in-flow manifold and at least one out-flow control valve is in communication with the out-flow manifold. The branch valves, air valves, the in-flow control valve and the out-flow control valve are operable to provide a chosen flow rate of the liquid and a selected foam product flow rate at a selected density of the foam product.
