Effects of operational processes and equipment in palm oil mills
The characteristics of POME are largely dependent on the efficiency of the operation and process control of the mill. In Malaysia, the widely used method to extract palm oil from fresh fruit bunches (FFB) is by wet palm oil milling process (Wu et al., 2010).The unit operations used for extractions are a steriliser, a stripper, a digester, a Mill output and power consumption not only depends upon the input materials but also on the desired fineness (200 / 90 Micron) of the raw meal produced; hence a careful evaluation and targetOptimizing Raw Mills Performance ; the Materials
