A coffee densifier is disclosed. The coffee densifier comprises an elongated chamber, a densifier motor, a shaft, a plurality of densifier members, a discharge door actuator, a densifier motor load sensor, and a controller. The plurality of densifier members are fixed to the shaft and configured to polish a plurality of coffee particles of the ground coffee within the elongated chamber when the plurality of densifier members are rotated by the shaft through the ground coffee within the mixing chamber. The controller configured to signal the discharge door actuator to move the discharge door to increase or decrease a density of the ground coffee exiting the chamber through the discharge opening when the densifier motor load is outside a predefined densifier motor load operating range.
