• How does a palm oil mill work?
  • A palm oil mill typically adopts a solvent-free process that uses steam and water for oil extraction. Interestingly, the process to extract the oil from the palm fruitlets has remained relatively unchanged for the past 50 years. Figure 1 shows the block flow diagram of a typical palm oil mill for the production of crude palm oil.
  • What is palm oil winning process?
  • The oil winning process, in summary, involves the reception of fresh fruit bunches from the plantations, sterilizing and threshing of the bunches to free the palm fruit, mashing the fruit and pressing out the crude palm oil. The crude oil is further treated to purify and dry it for storage and export.
  • How do palm oil mills extract CPO?
  • Two common methods to extract CPO by the mills are either using a dry or wet process. The most common method used is the wet process which involves a large amount of water and steam in the process to remove dirt and to sterilize the fruit bunch in different steps, thus generating a high volume of effluent termed as palm oil mill effluent (POME).
  • What is a typical palm oil mill?
  • Figure 1 shows the block flow diagram of a typical palm oil mill for the production of crude palm oil. The major unit operations include sterilisation, stripping, digestion and pressing, clarification, drying and storage.
  • How efficient is palm oil milling in Malaysia?
  • Palm oil milling is a well-established process and the process has remained relatively unchanged over the past few decades. This has in part caused the national OER in Malaysia to remain stagnant over the years. It has been estimated that the milling efficiency of a well-managed mill is approximately 90%.
  • How is crude palm oil extracted?
  • The first stage of crude palm oil extraction is the sterilization or steaming process (Hashim et al. 2012). The fresh fruit bunches are exposed to high-temperature pressurized steam at 140 ¡ãC for 75¨C90 min to deactivate the natural hydrolytic enzymes which breakdown oil to free fatty acids.
