A condiment grinding apparatus (46, Fig.12) comprises a female grinding element 2 having a first aperture 14 extending therethrough. The first aperture 14 defining an inner surface 15 of the female grinding element 2, wherein the female grinding element 2 is corrugated to provide first corrugated surface portions in the inner surface and second corrugated surface portions on an outer surface of the female grinding element. The condiment grinder (46, Fig. 12) also includes a male grinding element 5 having a second aperture extending 38 therethrough. The male grinding element 5 is corrugated to provide third corrugated surface portions in an outer surface and fourth corrugated surface portions on an inner surface of the male grinding element. There is also a polymeric core 6 in the male grinding element 5 in contact with the inner surface of the male grinding element 5. The core 6 having a third aperture 42 extending therethrough, the second and third apertures 38, 42 being aligned for receiving a grinding shaft (43, Fig.12). The inner surface of the female grinding element 2 and the outer surface of the male grinding element 5 form a cavity for grinding condiment between the first and third corrugated surface portions upon relative rotation between the shaft (43, Fig. 12) and the female grinding element 2. The condiment grinder (46, Fig. 12) is a light weight, low cost grinder assembly for a condiment grinder and wherein preferable each of the male and female members is a composite of a polymer part and a corrugated steel grinding member which is advantageously produced by pressing sheet metal. |
