Zusammenfassung:	The present invention relates to a coffee machine including a grinder configured to grind coffee beans, and provides a coffee machine devised to be able to bring an air volume for separating waste such as chaff as close as possible to a target air volume. A first grinder 5AM configured to grind coffee beans; a fan 60A1 configured to generate a wind pressure by rotating to separate waste from the ground beans ground by the first grinder 5AM; a fan motor 60A2 configured to cause the fan 60A1 to rotate; and a control unit 11a configured to control rotation of the fan motor 60A2 according to a set value (PWM value) are provided, and the control unit 11a acquires information (the number of rotation pulses) related to a rotation speed of the actually rotating fan motor 60A2, corrects the set value (PWM value) based on the acquired information, and controls the rotation of the fan motor 60A2 according to the corrected set value.
