The device for grinding food grains such as flaxseed, includes a bulb rotatably within a bowl. The bulb and the bowl together delimit a functional area, a lower area of which includes a device for moving the grain to a lower area having teeth to grind the grain. There is a device for maintaining, between the bulb and the bowl, at the level of the functional area, a clearance to allow for the grinding of the grains and to avoid all contact between the bulb and the bowl at the level of the space. The space is formed so as to prevent any grains returning from the lower area to the upper area. The invention further concerns a mill equipped with such a device for grinding food grains.

A coffee bean grinder is provided, comprising a housing assembly, a shaft component, and a securing member. The shaft component is assembled in the housing assembly. When a coffee bean grinding complex is formed by an inner grinding member of the shaft component and an outer grinding member of the housing assembly, the shaft component and the housing assembly can be easily assembled and secured through the structural configuration of the securing member, and also through which, the shaft component and the housing assembly can also be disassembled for cleaning and maintenance after grinding operation.

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr, a frustoconical burr, and an interlocking plug. An internal bore of the frustoconical burr has an upper cylindrical surface adjacent the top end, an interlocking portion adjacent the bottom edge, and a tapered side surface. The interlocking plug is shaped to extend through the internal bore of the frustoconical burr, and includes an upper cylindrical portion that fits through the upper cylindrical surface, and a lower portion that includes a sidewall surface to which is also tapered such that the sidewall surface interlocks with the side surface of the frustoconical burr.

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).
