Oil palm milling extraction methods have not changed since the pioneering work of United Plantation’s Tan Sri Bek-Nielsen who was inspired by Unilever’s work at Mongana in the Belgian Congo in the early 50’s. The traditional method of first digesting and continuously pressing thereafter by a single or double mechanical screw press has survived in the realm of prices versus robustness and reliability but inherent limitations in the method are a major cause of both Palm Kernel Oil (PKO) loss and Crude Palm Oil (CPO) loss.

A more efficient method prescribes the decoupling of the traditional digester combination and a reassembly of specific apparatus engineered to optimise the critical steps linked to efficient separation of oil from cellulosic matter. At the second stage pressing, up to 95 percent of the oil is removed by a novel vertical axis single helical spiral screw press by forcing the mesocarp fibre through 3 separate compression zones. Induced maceration, removing kernel nuts before pressing, the introduction of an intermediate hydration process between a second and third stage pressing eliminates kernel oil losses and significantly reduces crude oil lost on pressed fibre.

RobiahDr Robiah Yunus is a Professor in Chemical Engineering from the Department of Chemical and Environmental Engineering, Faculty of Engineering, Universiti Putra Malaysia (UPM). She is currently the Dean of School of Graduate Studies at UPM. She is a chartered chemical engineer, and a fellow of the Institution of Chemical Engineers, UK. She obtained her first degree in Chemical Engineering from the University of Alabama USA followed by the MSc degree in Integrated Design of Chemical Plant from the Leeds University, UK and PhD in Chemical Engineering from UPM.

She is very active in research primarily in the area of biobased products synthesis and technology development. She has led numerous research projects worth more than RM15 million and has authored about 110 publications in international reputable journals. Her active and leading involvement in research has resulted in development of 2 patents and 6 pending patents. Currently, she is leading a national long-term research (LRGS) program on Palm Oil Milling worth RM5.855 million.

There are a total of 50 researchers from 5 universities involved in the program. This program aims to enhance the productivity and sustainability of the Malaysian palm oil milling industry by improving the existing milling technologies and increasing biomass utilization. Specifically, the program is to elucidate the fundamentals issues in the existing milling technology for possibility of improving oil extraction rate (OER) by reducing oil losses in palm oil mill. Currently UPM and Fibaloy International is working on the development of a new extraction method for palm oil.
