Brew Group
The brew group is the assembly where espresso is made. In the brew
group, ground espresso beans are tamped and hot water is forced
through the ground espresso beans. This action creates espresso, which
is then transferred through the product outlet and into the cup.
After the espresso is extracted, the used grounds are directed into the
grounds chute and into the grounds bin.
Two 38Vdc motors drive the double-piston brew group.
