MPD Method (Mass Passing to Digester) for Estimating the Potential of Industrial Oil
Given the frequent fluctuations in the oil extraction rate (OER) during the processing of fresh fruit bunches of OxG and E. guineensis materials, different alternatives have been proposed for estimating oil potential and explaining the causes of such variations. However, despite the various existing me- thodologies, it has not yet been possible to fully determine the responsible factors that affect OER. For this reason, the analysis of the mass passing through the digester (MPD) was proposed as an option for evaluating bunch quality at palm oil mills. MPD analysis allowed to evaluate the oil potential of producers who supply oil palm fruit to palm oil mills, determining their incidence (positive or negative) on the total yield. This was achieved by characterizing a sample of mass of sterilized fruit taken at the exit of the drum and classifying its com- ponents: normal fruits, aborted fruits, parthenocarpic fruits, and impurities. Our results provide preliminary information of great value for the oil palm agroindustry, since it is possible to infer that MPD can be used as a tool for the prediction of the behavior of OER within mills and to address OER fluctuations. On the other hand, it was observed that it is feasible to develop theoretical models that relate the intrinsic variables fruit to bunch, such as moisture in the mesocarp, the amount of mesocarp, and MPD to bunch, etc.
