B14. Brewing group and piston
The elements of the brewing group and piston are manufactured in resin and are the elements used to
brew
the ground coffee dose.
Azkoyen offers three coffee groups with different features and capacities. The Vitro S5 models may
incorporate any of the three types of groups:
1.
AZK 10
. It can process 5 to 8 g coffee doses
2.
AZK 20
. It can process 10 to 14 g coffee doses
3.
AZK 30 or Variable group
. It can process 7 to 14 g coffee doses
AZK 10
AZK 20
AZK 30 Variable
The
groups
feature moving parts that are activated by a 120/230 VAC motor, which can rotate a bushing
that pushes the
coffee holder
from the
grinder to the piston (filling and brewing positions). A cam rotates
as the motor rotates, which presses a
micro-switch
, indicating to the electronic card that the group has
reached the brewing position.
To remove any of the 3
groups
from their anchoring position, rotate the two levers that secure it to its
support, as shown in the image below. If the group is in the brewing position, extract the piston to
remove it.
