Belle Epoque Digital
Vertical 1 or 2-groups espresso coffee machine. Outer case in copper and brass, treated with particular protective anti-oxidizing processes.
Continuous delivery by push-button. Automatic boiler filling is standard. Filter for mixed use either with ground coffee or with coffee pod upon
request.
An espresso coffee machine is basically made up of the following elements:
Boiler
Is used to contain the hot water and steam and is made of copper so that its properties do not deteriorate over the years.
Brewing group and heat exchanger
The brewing group is the component which, when attached to the filter holder (containing the filter and the ground coffee or the coffee pod),
brews and delivers the beverages when supplied with hot water.
The heat exchangers, one for each group, are immersed in the water and are used for fast heating of the fresh water from the network to the
optimal temperature and to prevent thermal imbalances within the system.
Heat source
This is normally provided by an electric heating element immersed in the boiler which heats the water and provides the steam.
Electric pump
This device is used to raise the pressure of the network, which is normally inadequate for the purpose, to a pressure of 9 bars which is ideal
for making the best coffee.
Steam tap
It allows steam to be delivered to give the indispensable "froth" to the milk used for preparing cappuccino, for heating water and punches and
for preparing chocolate drinks.
Water tap
It allows water to be delivered for preparing hot drinks, tea and tisanes.
Control instruments
Manometers:
show the current pressure in the boiler and the pump's operating pressure.
Pressure switches:
control the pressure and switching on of the heat sources to keep the boiler water temperature constant.
Level gauge:
shows the water level in the boiler.
Hydraulic diagram
As can be seen from the hydraulic diagram, the water for preparing the coffee is not taken from the boiler, but comes directly from the water
mains and is heated in the heat exchangers by the heat of the water contained in the boiler.
Wiring diagram
The machine is connected to the power supply network by means of the electric cord supplied. As we can see from the wiring diagram, there
are two circuits:
- power supply circuit for the operational electric components (solenoid valves, pump motor, electronic control centres).
- power supply circuit for the boiler heating element.
Main switch
The machine is fitted with a three-position power switch:
Position 0:
no power supply to the internal components
Position 1:
power supply to the operational electric components
Position 2:
power supply to the operational electric components and to the boiler heating element
