Coffee grinder for grinding coffee beans, comprising a container or supply element for coffee beans and a grinding device for grinding the coffee beans. The grinding device comprises a first and a second grinding element between which the coffee beans are ground, the distance between the two grinding elements in the grinding process determining the degree of grinding of the ground coffee, and at least one grinding element being driven by a motor. An adjusting element is provided, with which the distance between the two grinding elements can be adjusted by rotating an adjusting element, and a magnetic rotational position sensor, which directly or indirectly determines the absolute rotational position of this adjusting element as a measure of the distance and provides it for the further control of the coffee grinder.

The mill for spice products, in particular such as cinnamon sticks, houses a reservoir for storing the spice product. The reservoir communicates through a passage, with a grinding mechanism. The reservoir includes a mechanism for fragmenting the spice product. The mechanism for fragmenting are defined by a crusher of the spice product.

A grinding attachment for use with a coffee machine an upper grinding tool arranged inside a casing, and a lower grinding tool (11), which can be rotated rotatable relative to the upper grinding tool during a grinding operation. An adjustment device adjusts a degree of grinding of a material to be ground with the grinding tools. The upper grinding tool is attached to a support. The support for the upper grinding tool is displaceable in the vertical direction and is secured torque-proof on an element of the adjustment device. The adjustment device comprises a guide for the support which, during the rotating of the adjustment element, moves the support together with the upper grinding tool in the vertical direction for adjusting the grinding gap.

The grinder includes a container having a discharge opening for material to be ground; first and second grinding tools, the first tool rotatable relative to the second grinding tool about a rotation axis for crushing the material in a gap between the tools. The second tool has an inlet channel limited by a wall section around the axis for supplying material into the gap and is moveable relative to the first tool axially to the axis. A collar seal between container and second tool has a through-channel for discharging material into the inlet channel and is stationary relative to the container so that a first annular collar seal section limiting the through-channel contacts the container and overlaps the second tool wall section toward the axis. The collar seal includes a second annular section connected to the first annular section via an elastic spring and supported on a contact surface.

A foodstuff dispensing system is provided in which a foodstuff dispensing hopper comprises a gate rotatably mounted adjacent a bottom opening for selectively opening and closing the bottom opening. The hopper further comprises coupling means for detachably and rotationally coupling the hopper to the apparatus, and an interlock mechanism for interoperating with the gate to enable rotation of the bottom opening relative to the gate into an open position when the coupling means is being rotationally coupled to the apparatus and to enable rotation of the bottom opening relative to the gate into a closed position when the coupling means is being counter-rotationally decoupled from the apparatus

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr to an end, the shaft having an axis of rotation, and a burr having an external surface, the burr having an internal bore that extends therethrough. The internal bore has a surface which is tapered with respect to the axis of the shaft. An interlocking plug is shaped to extend through the internal bore of the burr, the interlocking plug having a sidewall surface which is tapered with respect to the axis of the shaft, such that the sidewall surface abuts the surface of the burr to seat the interlocking plug within the burr. An adjustment knob engages the end of the shaft for locking the interlocking plug within the burr.
