DEVICE FOR PRODUCING MILK FOAM

摘要

The present invention provides a device 1 for producing milk foam, which makes use of Couette flow and a high shear stress that is accordingly applied to a milk-air mixture between two concentrically arranged cylinders 2, 3. 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 6 between the two cylinders 2, 3 and expands. The parameters of the device 1 that mainly influence the foaming effect are the width of the gap 6 and the relative rotation speed of the cylinders.

1. Device for producing milk foam comprising:
an outer cylinder; an inner cylinder arranged concentrically within the outer cylinder; a fluid inlet and a fluid outlet; the outer cylinder and the inner cylinder are rotatable with respect to each other; a gap is formed between the outer cylinder and the inner cylinder; and the gap connects the fluid inlet with the fluid outlet.
