In order to improve crude palm oil quality and value, most customers are looking for further purifying crude palm oil. In general, there are two parts to purify crude palm oil in palm oil production process. One is crude palm oil clarification station, and the other is crude palm oil refinery plant.
Oil clarification station removes physical impurities from crude palm oil
Crude palm oil clarification station is the last part of the complete palm oil processing plant. After pressing, crude palm oil will go into crude palm oil clarification station, which includes oil clarification tank, vibrating screen, and centrifuge to remove residue fiber, sand and other physical impurities in the crude palm oil.
Machiens used in crude palm oil clarification section
Crude palm oil clarification station is just to purify crude palm oil simply. You can get high quality crude palm oil which can be sold to the crude palm oil market or palm oil refinery plant.
However, some customers want to get edible palm oil that is qualified the standard. So palm oil refinery plant is necessary for them.
Oil refinery plant removes invisible impurities from crude palm oil
Palm oil refinery plant is used to purify invisible impurities from crude palm oil, like gums, FFA, pigments and bad odors. It mainly includes four process: degumming, deacidification, decolorization and deodorization process.
Three types of palm oil refinery machine
1. Degumming process is mainly to remove gums in crude palm oil by adding hot water (there is a little P-acid in water).
2. Deacidification process is to use alkali like (NaOH) to neutralize FFA in oil. After reaction, this process will produce soapstock, which will be separated from oil. Soapstock is by-product in crude palm oil refining process, and can be used to make soap in soap making factory.
3. Because the color of crude palm oil is red and dark, in order to make color light and bright, palm oil will be sent to decolorization tank or tower. Use the white clay /bleaching earth to absorb the pigment away, and then use vibrating filter to separate the waste clay.
4. Finally, in order to let palm oil smell good when cooking, palm oil will be sent into deodorization tank or tower. Use direct steam to take odors away.
