<p>The dosing device comprises: a coffee grinder (5) for making coffee powder from coffee beans; a motor (9) for actuating the coffee grinder (5); a dosing chamber (21) wherein the coffee powder produced by said coffee grinder (5) is discharged, said dosing chamber being at least partly delimited by a first wall (33), which may be opened on command for discharging the coffee powder from the dosing chamber, and by a second wall (31), mobile by the effect of a volume variation of the coffee powder in said dosing chamber (21); an actuator (37) for controlling an opening movement of said first wall (33); an electronic control device (59 that based on the position of the second wall, causes the stop of the actuating motor (9) of the coffee grinder and the actuation of said actuator (37) for controlling the opening movement of said first wall and the discharge of the coffee powder from the dosing chamber. The second wall (31) is associated to a detection system (45) of a plurality of dosing positions of the second wall. The opening of the first wall (33) is set through the electronic control device (50), in connection with the detection system (45) and with the actuator (37), when the second wall (31) has reached one of the above dosing positions.</p> |
