The invention relates to a system for preparing milk and milk foam in drinks machines, such as coffee machines and similar pieces of equipment, which are provided with a heater unit for heating the milk and/or the milk foam with steam. The system contains, according to the invention, a feed for the milk and/or the milk foam and a separate feed for the steam, which is fed directly, as a heat-transfer medium, into the milk and/or the milk foam in the heater unit, which operates as an injector. The system allows a high heating capacity along with simultaneously good regulating capability and minimized thermal inertia. Since the foaming operation and the heating operation are separated from one another, the quality of the milk foam remains unimpaired by the heating operation. |
