Milk Island
(Talea series only / optional)
Function:
The function of the Milk Island is based on
the Venturi principle in combination with a
Vernay valve.
1.
The steam fl owing into the Venturi
valve produces a high subpressure that
absorbs the milk.
2. In turn, the milk generates a
subpressure when fl owing past the
Vernay valve that sucks air in via the
Vernay valve.
3. The milk is frothed using this air.
4. The milk froth and the steam make
contact in the Venturi nozzle and the
milk froth is heated up.
