A method for measuring a quantity of coffee Mor Mthat a grinding burr of a coffee mill driven in rotation by a motor dispenses in a predetermined number of revolutions Nof the grinding burr or in a predetermined time interval T. According to the method: the average speed Vof the grinding burr in a number of revolutions Nor respectively in a time interval Tis measured; and the quantity or mass Mof coffee dispensed in the number of revolutions Nor respectively the mass Mof coffee dispensed in the time interval Tis deduced as a function of the speed Vfrom an experimentally obtained stored correspondence table (V, M) or (V, M).

Method for measuring the quantity of coffee dispensed by a coffee mill and appliance comprising such a mill

A method for counting the number of revolutions of a burr of a coffee mill driven in rotation by an electric motor. According to the method: at least one electrical parameter Pof the motor that varies in proportion to the speed of said motor is measured in a regular time interval T; the speed Vin each time interval Tis calculated from the parameter Pbased on an experimentally obtained relation; and the number of revolutions Nmade by the burr in each time interval Tis calculated from the speed Vdetermined.
