A mill includes a first mill having a first grinding region, a second mill having a second grinding region opposed to the first grinding region and provided to be rotatable relatively to the first mill, and a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other, and the heat radiation mechanism is provided in a portion except for the first grinding region and the second grinding region.

A coffee densifier is disclosed having an elongated housing having a chamber configured to receive ground coffee. The mixing chamber has an inlet end opposite a discharge end. The discharge end has a discharge door. The densifier has a shaft driven by a motor, the shaft extending along a longitudinal length of the mixing chamber. The densifier has a plurality of paddle-less pins fixed to the mixing shaft and configured to agitate a bed of coffee within the mixing chamber.

An automated coffee grounds homogenizer is disclosed. The homogenizing tool comprises a body having a central axis, a plurality of stirs extending away from the body, and a gear means for randomly rotating the plurality of stirs about the central axis of the body. The gear means has differently sized gears that may be interchangeable with one another whereby the path of rotation of the stirs about the central axis of the body may be changed by switching out one of the plurality of gears with another of the plurality of gears. In a similar vein, each stir is preferably magnetically detachable to the gear means wherein switching out the placement of each stir changes the path of random rotation of the stirs about the central axis.

A coffee grinder, in particular for the installation in a fully-automatic coffee machine, including an electric drive motor (1) for driving a grinding unit, wherein a reduction gear (4) formed as a planetary gear is arranged between drive motor (1) and grinding unit, with the sun gear (3) of this planetary gear being drivable by the drive motor (1). The planetary gear includes multiple planetary rods (8) arranged in the circumferential direction around the sun gear (3), these rods including a first axial portion (7) meshing with the sun gear (3) as well as an axially neighboring, second axial portion (9) with a second diameter different from, preferably smaller than, a first diameter of the first axial portion (7), with this second axial portion meshing with a stationary ring gear (11). The toothed racks are arranged to drive an output element (15) with their first axial portions (7).
