Design and development of a palm kernel nut cracking unit

The object of this research is the cracking nuts oil palm (Elaesis guineensis). tree one greatest economic assets a nation can have, provided its importance realized and fully harnessed. After extraction from fruits, virtually all methods involved in kernel nut both traditional small-scale exist scattered or separate units operations. Hence, focused on designing unit incorporating separator form screen to cracked shell kernel. result shows that there were significant difference (p≤0.05) among moisture content nuts, shaft speed machine weight (feed rate), having between: – cracker; feed rate; rate. There interaction between cracked, uncracked shell, damaged, undamaged kernel, breakage ratio. While, was no content, weight. also indicated for highest 1,800 rpm at rate 700 kg/h contents, efficiency between10 90 %, which implies increases with an increase speed. However, it observed higher cost damage speeds rates, problem. ratio ranged 1.040–7.85 rates contents. increased but decreases
