A grinder for grinding beans of plant-based products and generating a ground powder can include: a grinding chamber; a wheel motor having a shaft defining an axial direction; a rotating grinding wheel and a stationary grinding wheel housed in the grinding chamber, wherein the rotating grinding wheel is connected to the shaft of the wheel motor and is configured to rotate around the axial direction, and wherein the stationary grinding wheel is stationary against rotation and is configured to axially move in both ways in the axial direction; and a device for resetting position of the rotating and stationary grinding wheels. The device can include: a mechanism for axially moving the stationary grinding wheel; an electric motor, coupled to the mechanism, for actuating the mechanism; and a way to stop the electric motor as soon as a contact state is detected between the stationary and rotating grinding wheels.

A unit of a coffee apparatus, in particular a coffee machine for brewing a coffee drink, includes a coffee bean container for storing the coffee beans, a portioner for portioning the coffee beans for an individual portion, and a grinder for grinding the portioned coffee beans. The coffee bean container and the portioner are formed in a common container module. The unit has a module receptacle, by which the container module can be connected during use and removed after use, and the container module has settings for a portion amount and a degree of grinding, which can be selected by the user. The portion amount setting influences the portioner and the degree of grinding setting influences the grinder. A simple, cost-effective and easy-to-use information exchange module between coffee container and coffee apparatus is thereby created.
