2.6.20 Autosteamer (optional)
The "Autosteamer" system, supplied with certain ver-
sions with display, can be used for automatically heating
and foaming milk at the programmed temperature. Be-
low is listed the operating principle of the autosteamer:
t Press the appropriate button (
1
) placed on the base
to the left of the machine;
t
opening of the solenoid valve (
2
) with consequent
flow of steam from the boiler to the autosteamer
nozzle;
t
simultaneously, the system activates the air pump
(
6
) which is controlled by the control unit (
3
) and
powered by a processor (
8
). The regulation of milk
foaming can be made by changing the amount of air
intake operating the valve (
5
);
t
after passing through the non-return valve (
4
), the air
mixes with the steam in the "Mixing interface" (
11
);
t
leakage of steam from the nozzle (
9
);
t
the probe (
10
) connected to the electronic unit of the
machine detects the temperature of the heating milk;
t
Once the set temperature of the milk has been
reached, the electronic system blocks the flow of air
and steam.
