5 - BREWER UNIT FOR COFFEE PODS
The adopted brewer unit is used to brew coffee exclusively by means of
continuous strip “ESE” pods (servings) with 100/200 doses. The pods
are made up with an optimum coffee dose.
The unit works as follows:
When a selection is made the serving drive motor positions the pod in
the brewing zone under the flow-through boiler. The unit motor lifts the
piston until hermetically closing the brewing chamber.
The three-way solenoid valve is opened so that the pressure boiler is
connected to the flow-through boiler located above the brewer unit.
The pressure boiler maintains the water at a temperature of
approximately 80° C (ideal for instant products) and the flow-through
boiler heats it up to 95-100° C (ideal for espresso coffee).
The brewing chamber is kept hot at
the same temperature of the flow-
through boiler.
The pump delivers the programmed amount of water that is accurately
computed by the volumetric counter. At the end the three-way solenoid
valves are closed and the water still in the flow-though boiler is expelled
through the third way of the valve. Then the unit motor is activated,
lowering the piston until opening the brewing chamber.
The “serving” drive motor is started, dragging the serving out of the
brewing chamber.
At this point the unit is ready for a new selection.
In order to maintain the correct temperature up to the dispensing point, a
special tube heated by a special permanent low-consumption heating
element is used.
