Abstract

A control unit, a pump for supplying infusion water, a boiler for heating the infusion water, an infusion unit, a coffee mill, and a user interface including a selector for a beverage and/or a ground coffee dose. The coffee mill has a hopper for coffee beans, a rotating and a non-rotating grinder, a motor for directly or indirectly driving the rotating grinder, all with capability to adjust the distance between the grinders. A first sensor detects a number of turns and/or speed of the motor and/or of the rotating grinder. A second sensor detects a distance between the grinders. The control unit stores an algorithm for calculating a correct dose of ground coffee, configured to receive the value of ground coffee selected and the distance between the grinders to automatically generate the number of motor turns necessary to obtain the correct dose of ground coffee.
