A method for actuating an electric motor includes modulating a drive power provided to the electric motor by using a ramp function for a change in rotational speed of the electric motor from a starting rotational speed to a target rotational speed. The target rotational speed is only reached after at least 200 ms, starting from the starting rotational speed. An apparatus, a fully automatic coffee machine having the apparatus, a computer program product and a computer-readable storage medium are also provided.

Actuators and interchangeable cartridges that achieve a grinding or grating different substances without cross-contamination. The actuators and cartridges are disclosed are uniquely designed for ready push-on, push-off mounting in a manner that affords proper alignment of the cartridge in the actuator. The cartridges may include a container portion and a mount portion, each with a grinding element arranged at an output thereof. As the container and mount portions move relative to one another, their respective grinding elements move, achieving a grinding or grating of substances in the container. Various embodiments and variations are disclosed.

A roast level of coffee grounds used in a coffee brewing operation may be characterized based at least in part on one or more weights of the coffee grounds determined during a grinding operation, and in some instances, may be used to determine one or more brewing parameters used in the coffee brewing operation. In addition, in some instances the roast level of the coffee grounds may be determined during a grinding operation and used to control the amount of coffee grounds generated during the grinding operation.

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.
