How to separates crude palm oil into palm olein and palm stearin?
Palm oil is the largest vegetable oil in the world in terms of production, consumption and international trade and has a wide range of uses. In order to improve the quality of palm oil, many businesses will choose to refine and fractionate red palm oil. So how to separate crude palm oil into palm olein and palm stearin?

First of all, crude palm oil needs to be refined through cooking oil refining machine. Cooking oil refining includes four steps: degumming, deacidification, decolorization and deodorization. From this, we get refined palm oil, which is then processed through palm oil fractionation machine. It is separated into palm olein and palm stearin. The process of palm oil fractionation is as follows: refining palm oil→preheating→freeze crystallization→filtering→palm olein and palm stearin.
Process of palm oil refining and fractionation
Palm oil fractionation machine means that palm oil is divided into two parts by controlling the cooling and crystallization process of palm oil, low melting point liquid phase (olein) and high melting point solid phase (stearin). Due to different geographical locations, different countries have different temperature requirements for palm oil fractionation. There are three common palm oil fractionation temperatures: 18°C, 24°C and 36°C. Mainly need the following machines:
Palm oil fractionation machine
●1. One heating tank, two cooling crystallization tanks. There is a thermal oil heating coil in the heating tank, and a cooling water coil in the cooling crystallization tank. The cooling crystallization tank is equipped with a stirrer to ensure that the cooling crystallization process is carried out evenly.
●2. Plate filter. Used to separate palm soft butter from hard fat. What comes out of the strainer is palm soft fat, which can be poured directly into the soft fat jar. The palm stearin taken from the middle of the filter plate is melted in the lower stearin tank and poured into the stearin tank.
●3. One set of air compressor. It is used to generate compressed air to remove remaining soft fat from hard fat.
●4. One set of air cooling system. Used to make cooling water for cooling crystallization tanks.
