Perfect milk foam



The finest nuances of hot or cold milk foam -from solid to creamy- can be produced.


Key to foam production is the pulsing valve for precise air dosing.


The Franke FoamMaster is installed, configured, and tested in Switzerland.


Each machine is tailored to the specific customer needs.

Cappuccino, latte macchiato or coffee with caramel flavor: The coffee culture of Italy and America spreads across the globe. Franke, the world's leading supplier of professional, fully automatic coffee machines, addresses this trend with the FoamMaster. By pressing a button, the machine not only produces any coffee variation - dark classic, latte macchiato, flavoured espresso, etc. -  but also hot and cold milk drinks with foam.

Variable milk foam quality
QUO developed the milk frother concept and supported Franke up to functional models and testing of them. The requirement was to produce foam for cold milk as well. Gear pumps rise and swirl the milk but only produce foam if air has been previously added and can work against pressure. This counter-pressure must be accurately adjusted for different foam quality. The same applies to the air supply and conventional air valves are not a valid option in this context. QUO took vehicle fuel injection as a model and built a pulsating valve for precise air dosing. This allows the production of the finest foam gradations from solid to creamy. Foam quality parameters can be easily set up via the electronic control for specific drinks.

Multi-beverage system
With the FoamMaster, Franke has developed a multi-beverage system that meets the latest, most stringent requirements. Operation is extremely straightforwards thanks to a touch screen user interface with intuitive software, making it suitable for full-service restaurants, as well as for self-service.
