A device for producing fluid foam includes a container where the fluid can be accommodated, and includes a foaming tool rotatable in the inner volume of the container. The texture and the porosity of the fluid foam obtained are provided by shear energy coming from Couette Flow effect and depend on the dimension of the foaming tool with respect to the inner volume of the container, on the location of the foaming tool from the bottom of the container and on the rotation speed of the foaming tool.

Impeller for food processor

A device for producing milk foam uses Couette flow and a high shear stress that is accordingly applied to a milk-air mixture between two concentrically arranged cylinders. The cylinders are rotated relatively to another. The high shear stress leads to an emulsion of the milk and the air, which is the basis for a foaming effect, once the emulsion flows out of a gap between the two cylinders and expands. The parameters of the device that mainly influence the foaming effect are the width of the gap and the relative rotation speed of the cylinders.
