2/1 Grinder with motor and adjusting rod
The grinder freshly grinds the coffee
beans with ahorizontal disk grinding
mechanism for each brew. The ground
coffee is transported by the ground
coffee spout to the brewer. The wire
at the end of the ground coffee spout
ensures that the ground coffee falls
into the brewing unit in acontrolled
way. Dispensing is time-controlled.
The grinding degree can be set on the
grinder. The grinder is connected to the
motor with aworm gear.
If the bean hopper is empty, this is
recognised by the current detection,
evaluated by the software and shown
on the display.
If the grinder is blocked or there is
ashort-circuit, this is also recognised by the current detection and shown on the
display. Errors are stored in the error list.
