Crude Palm Oil Refinery(CPO) Palm Oil Refinery is an important process in the palm oil mill plant to ensure the quality and safety of palm oil. Itâ??s recommended to refine crude palm oil through our palm oil refining machines to get high-quality palm oil that is easy to store and can priced high. Refined palm oil can be packed and labeled for the local or global market. We offer you complete palm oil pressing refining plant solutions, from plant layout design to palm oil equipment manufacturing, debugging, and installation. Crude Palm Oil Refining Plant Working Stages The main steps of crude palm oil refining are degumming, deacidification, bleaching, and deodorization.

RBD olein & RBD stearin Degumming The degumming process aims to remove the gum impurities in crude palm oil to make it suitable for further refinery processes. Water or acid is added to remove phospholipids and gums. Neutralizationg Alkali solution (typically sodium hydroxide) is added to neutralize free fatty acids. Deacidification is a process that has a great impact on palm oil quality. If there is a problem with the neutralization process, the following decoloration will be greatly affected. The free fatty acid in crude palm oil can affect the stability and relish of palm oil. We can add some lye to neutralize the free fatty acid, this process is also called alkali refining. Bleaching The palm oil bleaching process is to remove oil pigment, residual soap, and metal ions. All the pigments can be removed by the adsorbents method. The bleaching process can improve the oil color, relish, and increase the oxidation stability, thus providing a good condition for the deodorization process. Deodorization Steam distillation removes volatile components that cause odors. The palm oil deodorization section plays an important role in improving palm oil quality. The refined palm oil is nearly colorless and transparent in the liquid state and white in the solid state.
