A grinding device includes: first and second grinding elements, the first grinding element being rotatable relative to the second grinding element around a rotary axis for grinding coffee beans between the grinding elements into a powder; a carrier wheel rotatable around the rotary axis for conveying powder on the carrier wheel to an outflow channel to output the powder; a housing surrounding the grinding elements and the carrier wheel and including the outflow channel, the second grinding element being stationary relative to the housing, a rolling bearing with inner and outer rings and rolling elements therebetween, the outer ring being stationary on the housing and the first grinding element, the carrier wheel and the inner ring being rotatable around the rotary axis together. An annular seal ring seals an intermediate region above the outer ring around the rotary axis between the carrier wheel and the outer ring.

A spice mill part, more particularly a spice mill lower part, for a spice mill, having a housing, which consists at least in part of a plastic material and which can be rotatably connected to a further spice mill part, more particularly a spice mill upper part. A receiving element is provided on the housing, in which receiving element there is arranged a milling element being particularly a milling ring, made from a ceramic material, with the milling element being clamped in the receiving element in a frictionally engaged manner by a compressive force directed substantially radially inwardly and acting on a self-contained outer bearing face of the milling element, the compressive force acting substantially along the entire circumference on the external bearing face of the milling element.

A grinder device is provided. The grinder device may include a container, a cap assembly configured to be friction-fit to the container such that the cap assembly is removably lockable to the container, and a grinding mill disposed within the cap assembly to perform a grinding operation of condiment disposed in the container. The grinding mill may include a movable grinder portion and a fixed grinder portion that are rotatable relative to each other, and the fixed grinder portion is engagable with the container to permit relative rotation between the cap assembly and the container.

A condiment dispenser (10) with a grinding mechanism (28) according to the present invention comprises: a first part (26) defining an aperture (24) and surrounding inner surface (32), both with lobed cross-sectional profiles; and a second part (36) that is inside the first part (26) and can rotate about an axis (16) relative to the first part (26). The second part (36) has an outer surface (42) and the second part (36) and outer surface (42) both have lobed cross-sectional profiles. The inner surface (32) of the first part (26) and the outer surface (42) of the second part (36) are spaced apart by a gap (38) which is larger at a receiving side (48) of the grinding mechanism (28) and narrows in the axial direction towards a dispensing side (50) of the grinding mechanism (28).

A calibration tool for a coffee grinder can receive an image from a camera. The image can depict coffee grinds produced by the coffee grinder. The calibration tool can analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds. The calibration tool can determine whether the representative grind size of the coffee grinds deviates from a predefined reference size by at least a threshold amount. In response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, the calibration tool can output an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size.
