Abstract
Disposable foaming device (100) for foaming a fluid (1) comprising a container compartment (20) and a foaming compartment (10), the container compartment (20) being pressurized by primary incoming air (14′) so that the fluid (1) is driven into the foaming compartment (20), wherein the foaming compartment (20) is provided with secondary incoming air (15′) to be mixed with the fluid (1) coming from the container compartment (20), the foaming compartment (10) being designed in such a way that the mixture of air and fluid (1) is moved under certain level of shear stress calculated so that it allows the mixture of air and fluid (1) to be emulsified in the foaming compartment (10). Typically, the foaming compartment (20) comprises an inner cylinder (11) and an outer cylinder (12), the inner cylinder (11) and the outer cylinder (12) being arranged concentrically so that a gap (13) is formed between them, the inner cylinder (11) being rotatable with respect to the outer cylinder (12), such that the mixture of fluid (1) and air is emulsified when driven through the gap (13).
