The palm nut is recovered as a major by-product in the processing of palm fruit (Elaeis guineensis) for palm oil. The nut is a composite biomaterial consisting of an outer hard shell and embedded softer kernel, which is extracted for the production of palm kernel oil. The oil is used as base material in various applications, including the manufacture of soap and edible fats, confectionery, glycerin and medicinal ointments. The economic importance of the palm kernel is further indicated by its use for animal feed, traditional medicine and other industrial applications. However, the quality of the oil depends, among other things, on efficient nut cracking, which will enhance effective separation of the kernel from the shell. Akubuo and Eje (2002) reported some efforts on the separation of the kernel from the shell but the efficiency of the experimental machine was limited largely because some shell particles and kernels have comparable sizes.
