METHOD FOR CONTROLLING A COFFEE MACHINE
First Claim
Patent Images
1. A method for controlling a coffee machine grinder comprising measuring an actual value of a physical quantity relating to a percolation process;
- and modifying a ground coffee grain size at least for the subsequent percolation so as to compensate for a possible detected deviation between said actual value and a reference value for said physical quantity, wherein as a consequence of user changes for the coffee machine, the control unit commands the execution of a preliminary coarse adjustment of a gap between grinding wheels by actuating an adjustment ring nut.

Abstract
The method for controlling a coffee machine grinder comprises one step of measuring the actual value of a physical quantity relating to the percolation process and one step of modifying the ground coffee grain size at least for the next percolation so that a possible detected deviation between the actual value and a reference value for the physical quantity is compensated.

- 13. A coffee machine comprising a grinder having an actuator for actuating a grinding wheel gap adjustment ring nut of said grinder, driven by an algorithm that compares an actual value for a physical quantity relating to a percolation process, measured by suitable measuring device, with a reference value for said physical quantity, and modifies a ground coffee grain size at least for a subsequent percolation so as to compensate for a possible detected deviation between said actual value and said reference value of said physical quantity, wherein a control unit is responsive to user changes for coffee machine settings to command the execution of a preliminary coarse adjustment of a gap between grinding wheels by actuating an adjustment ring nut.
