Method for generating milk froth
First Claim
1. A method for generating milk froth, comprising:
- supplying steam through a first supply line to a first outlet from a steam lance immersed in milk,supplying a mixture of steam and added air through a second supply line to a second outlet from the steam lance immersed in the milk, the second supply line being separated from the first supply line up to the first and second outlets from the steam lance,generating milk froth by mixing the steam and added air mixture from the second supply line with the steam from the first supply line only in the milk such that the mixing is external to the first and second outlets.

Abstract
Using a steam lance, the water vapor and compressed air are supplied to the milk via two pipelines which are separated from one another up to the outlet from the steam lance, wherein only steam is supplied through the outer pipeline at a vapor velocity necessary for breaking up the protein molecules of the milk, whereas a steam-air mixture is supplied through the inner pipeline to enrich the milk with the necessary air proportion, and is only mixed with the steam from the outer pipeline in the milk to be frothed. The steam lance includes the two pipelines arranged coaxially to one another, and an end piece which separates them from one another in the outlet area and has outlet openings for the two media, the steam and the steam-air mixture, designed as radial nozzles which are inclined horizontally and also relative to one another.
