- FR 2 617 736 is disclosed a device which makes it possible by starting with, on the one hand, water under pressure and, on the other hand, water, to which chemical or bactericidal products have been added, to produce foam intended for cleaning surfaces or objects.
- the device consists of two consecutive chambers. In the first cham- ber compressed air enters by means of a tube pierced with holes. Water under pressure, to which chemical products have been added, enters by means of the tube. Then the mixture of air under pressure and of water under pressure produces foam. This foam is conveyed into a decompression chamber, which completes the mixing of the products The volume of the chambers is calculated to obtain an optimum quality of the foam.
- the device comprises a housing body having a first inlet for feeding pressurized water; a propulsion jet positioned behind the inlet and in a direction of flow; a collection jet positioned behind the propulsion jet, which is flow-connected with a second inlet for feeding a chlorine-free alkaline foam cleaning agent, and a third inlet for feeding a hydrogen peroxide solution; and a turbulence chamber, into which an elongated jet body of the collection jet extends, the turbulence chamber being fitted with a chamber inlet for feeding compressed air into the chamber, such that a hydrogen peroxide foam is formed from a solution formed upon dosing an effective amount of the hydrogen per- oxide solution into the chlorine-free alkaline foam cleaner at a maximum of 60 seconds prior to contact of the hydrogen peroxide foam with a surface to be cleaned, the turbulence chamber further having a chamber outlet, through which the hydrogen peroxide foam leaves the chamber to contact the surface, the chamber

- Cleaning procedures used in for example the food producing industry typically involve an initial flushing/wetting of the contaminated area, surfaces, processing machines and other equipment, which need to be cleaned. This flushing is usually followed by appl i cation of foam to said area, surfaces, processing machines and other equipment. This foam is then flushed away after a certain period of time. Finally, said area, surfaces, processing machines and other equipment is disinfected by the application of a disinfectant. In some cases this disinfectant is removed by the flushing with clean water. This means that there is typically a successive change between the following pro- cedures: - Flushing with water alone
- the pressurized water is provided by a water pump to the water inlet of the housing of the mixing unit.
- the mixing unit is manufactured from a metal alloy, e g stainless steel.
- a metal alloy e g stainless steel.

- the method may according to a further embodiment comprise the step of choosing the injector, and thereby the injector inlet and outlet area in dependence of the available water pressure and/or available air pressure.
- the ratio between the area of the gap and the area of the injector inlet is a constant for one different injector that is used to change the quantity of foam produced
- One mixing unit A which is a mixing unit according to the invention, where air is blown in to the mixing unit around the injector opening and in a direction parallel to the flow of fluid out of the injector opening
- a mixing unit B wherein the air is blown into the mixing unit though a hole downstream and beside the injector outlet and in a direction substantially parallel to the flow of fluid out of the injector.
- the two mixing units A and B were then used to generate foam, which was blown onto a vertical, smooth wall sur- face.
- each mixing unit was used to generate foam into a 200 'iter plastic barrel, and the time it took to fill each barrel was measured.
- the results of these barrel tests were that the barrel which received foam from mixing unit A was filled with foam in a considerably shorter time than the barrel which received foam from mixing unit B, Since both mixing units in all experiments were supplied the same quantity of cleaning agent, water and air under equal pressure conditions, it may be concluded from these experiments that the foaming facilitated by the mixing unit ac- cording to the invention is significantly more effective than those known in the art.

- the air is supplied to the housing 6 via a suitable pipe 24, which is preferable connected with a compressor ⁇ not shown), and the first chemical agent is supplied to the housing 6 via a suitable pipe 26 which is in fluid communication with a reservoir ⁇ not shown).
- the water pipe 12 is fluidly connected to a water pump ⁇ not shown) for supplying pressurized water to the housing 6 of the mixing unit 2.
- the mixing unit 2 further comprises an injector 28 positioned inside the housing 6.
- the injector 28 has an injector inlet 30 and an injector outlet 32, which injector inlet 30 is fluidly connected to the first input line 20 for a cleaning agent, and which injector outlet 32 is fluidly connected to the fluid outlet 18 of the housing 6.

- Fig. 2 shows a partial perspective view of the embodiment of a mixing unit 2 illustrated in Fig. 1 ,
- air indicated by arrows 16
- said air will be evenly distributed around the injector cutlet 32 before it becomes mixed with the mix of water and first cleaning agent (said mix being indicated by arrow 36), thereby leading to a more effective foam production (se e.g. test results).
- the illustrated injector 28 has a continuously (i.e. stepless) increasing circular cross section in the direction from the injector inlet 30 towards the injector outlet 32.
- the inner dimensions of the housing 6 have a cylindrical shape adjacent to the fluid outlet 18, and the injector outlet 32 is positioned co-axially relative to said opening in the housing 6 at the fluid outlet 18.
