Pre-Cleaning System for Premium Palm Kernel Cake Production
Rohaya Mohamed Halim*; Mohd Firdaus Othman*; Che Rahmat Che Mat* and Andrew Yap Kian Chung*

Palm kernel cake (PKC) that contains more than 75% cell wall components, constituting mannose (35.2%), xylose (2.6%), arabinose (1.1% ), galactose (9.0%), lignin (15.1%), and ash (5.0%), is extensively employed as ingredient in feed rations for cattles, buffaloes and dairy cows. A palm kernel pre-cleaning system developed with three-stage winnowing columns to remove fibre and shell before pressing, had successfully produced premium PKC, also known as PURAFEX. It contained less than 8% shell, less than 12% crude fibre, and more than 16% crude protein. It is thus suitable to be used as feed ingredient for monogastric and ruminants.
