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

摘要

A method for measuring a quantity of coffee M_Ni or M_Ti that a grinding burr of a coffee mill driven in rotation by a motor dispenses in a predetermined number of revolutions N_i of the grinding burr or in a predetermined time interval T_i. According to the method: the average speed V_i of the grinding burr in a number of revolutions N_i or respectively in a time interval T_i is measured; and the quantity or mass M_Ni of coffee dispensed in the number of revolutions N_i or respectively the mass M_Ti of coffee dispensed in the time interval T_i is deduced as a function of the speed V_i from an experimentally obtained stored correspondence table (V_i, M_Ni) or (V_i, M_Ti).
