• What is crude palm oil refining?
  • To prevent iron oxidation, the storage tank is lined in a suitable protective coating. The oil at this stage is called the crude palm oil (CPO). The aim of refining is to convert the CPO to quality edible oil by removal of objectionable impurities to the desired levels in the most efficient manner.
  • What are the products of statolizer fractionation of palm kernel oil?
  • Consequently, the two steps Statolizer fractionation of palm kernel oil results in the following three products: a palm kernel stearin IV ¡«4 (for direct use as CBS), a palm kernel stearin IV ¡«7 (for use as CBS after full hydrogenation), and a palm kernel olein IV ¡«27.
  • Why is palm oil the most widely fractionated oil?
  • The original boo-ming of the dry fractionation process has helped palm oil to conquer a strong position on the commodity market. Today, palm oil is without doubt the most widely fractionated oil.
  • How is palm oil refining improved?
  • In this context, refining technologies have been improved, with the dual temperature deodo-rizer, the double condensing unit and the ice condensing system. The DOBI is a good tool to assess quality of the crude palm oil and its ability to be properly refined.
  • What is a flowchart of the palm oil fractionation process?
  • A flowchart of the fractionation process is shown Fig. 7.4. Simplified flowchart of the palm oil fractionation process The oil is first homogenized at 70 ¡ãC before the start of crystallization to destroy any crystals present and to induce crystallization in a controlled manner.
  • How is refined palm oil produced?
  • To produce refined palm oil (RPO), the objectionable impurities in the CPO are removed to obtain the required levels using two main methods: chemical or alkali refining and physical refining methods. Either of these is followed by fractionation as a final purification process to separate the oil into stearin and olein components.
