What's the secret behind creamy milk foam? CompactFoam in detail

Cappuccino, flat white, or latte macchiato: For many specialty coffees, the milk foam is just as important as the espresso. But what actually happens inside a fully automatic coffee machine before creamy milk foam ends up in the cup?

With Rex Royal, it’s all about the interplay of various components. CompactFoam allows you to prepare hot and cold milk as well as creamy milk foam for a wide variety of beverages. The system is available on various Rex Royal fully automatic coffee machines and is designed for professional use.

From the Refrigerator to the Cup

What begins for the guest with the push of a button sets several precise processes in motion inside the machine.

For hot milk beverages, the chilled milk must first be brought to the desired temperature. This is where the compact boiler comes into play. Inside, the milk is guided through a spiral-shaped tube and heated as it flows through.

The CompactFoam System then prepares the milk foam. This allows milk and milk foam for a variety of specialty coffees to be produced at the touch of a button.

The result: a wide variety of milk-based beverages—from cappuccino to flat white to latte macchiato—can be prepared automatically.

Why is this relevant in a professional setting?

Whether at a hotel breakfast buffet, in a restaurant after lunch, or in a self-service establishment, it’s not just the quality of a single cappuccino that matters. What’s crucial is that the desired quality remains consistent even when there’s high demand for beverages.

This is precisely where a key advantage of an automated milk system lies: the individual steps do not have to be performed manually for every drink.

For businesses , this means , above all , simpler workflows, faster beverage preparation, and consistent preparation of various milk-based drinks.

This advantage is particularly evident with the Rex Royal S500: coffee, hot water, CompactFoam, and steam can be dispensed simultaneously. Especially during peak hours, this parallel dispensing enables faster operations and saves valuable time.

Hot or cold? More options for the beverage menu

Milk foam doesn’t always have to be hot. CompactFoam also supports the preparation of cold milk and cold milk foam.

This opens up additional possibilities for the beverage menu. In addition to classics like cappuccino and latte macchiato, cold beverage concepts can also be implemented.

This flexibility is particularly appealing given the increasingly diverse world of beverages: Today, a professional fully automatic coffee machine is no longer limited to just espresso and café crème.
