Now more and more clients have realized the value of palm kernel oil processing business, especially in this year, we have received many enquiries about how to make palm kernel oil, how to refine palm kernel oil, how to purify palm kernel oil. In order to solve their confusions, today I will give you a brief introduction about how to refine palm kernel oil.
Palm kernel oil refining is a process to remove unwanted and undesirable elements from the crude palm kernel oil. The elements that are removed include the Free Fatty Acids, Phospholipids, Gums,Odour, Color etc. The palm kernel oil refining aims to make the vegetable oil clean and pure and improves the overall quality of the oil.
In order to achieve this goal, the palm kernel oil refining machine
will be needed. In order to get high quality refined vegetable oil, we need to through four steps, they are: degumming, deacidification, decolorization/bleaching and deodorization.
The first step, we need to remove the gums in crude palm kernel oil by adding the hot water and then settling a few hours.
The second step, we need to use alkali like (NaOH) to neutralize FFA in the crude palm kernel oil, during this oil refining process, it will produce soapstock, then we can separate it from the oil and use it to make soap.
The third step, in order to lighten the oil color, we need to use the white clay to absorb the pigment away, then use vibrating filter to separate the waste clay.
The fourth step: the crude palm kernel oil itself has some unpleasant odors, as well as other odors that produced in palm kernel oil refining process. For these, we usually use the direct steam to take odors away. After that, the final palm kernel oil will be refined once again through safety filter and then pump into oil storage tank for sale.
Through the above steps, you will get high quality RBD palm kernel oil that can directly sale for more profit.
