Abstract

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 in a gap between a housing, in particular an outer cylinder, and a rotating element rotating arranged therein. The device further comprises a milk supply circuit supplying the fluid inlet with milk and an air supply circuit supplying the fluid inlet with air, both supply circuits being independent from each other.

Description

technical field

[0001] The invention relates to a device for frothing a fluid, preferably for producing milk froth. In particular, the device is designed in such a way that it can be positioned within a fluid flow path to generate foam. The device of the present invention uses the high shear energy experienced by the fluid in the device as foaming energy for foam generation. Background technique

[0002] In the prior art, devices are known for producing milk froth, wherein the frothing of the milk is usually carried out in a batch process. For example, a device is known which has a reservoir into which milk can be filled. A rotating part in the reservoir, such as a stirrer arranged at the bottom of the reservoir, causes frothing of the milk. However, such devices for producing milk froth only produce a predetermined amount of milk froth at the same time (ie in one batch process). Thereafter, the unit needs to be emptied, preferably cleaned, and refilled with milk before ...
