Palm oil fractionation equipment separate palm oil into soft fat, hard fat and intermediates by controlling the crystallization point. The melting point of hard fat is 50°C and that of soft fat is 24°C.
Palm oil fractionation is an important process of palm oil refining plant. This new type of palm oil fractionation equipment includes a new type of crystallization tank, a diaphragm filter and advanced automatic control system. It uses a scientific cooling and crystallization process to improve the yield of liquid palm oil.on technology has strong adaptability and a wide range of applications. It can not only obtain palm oil and palm kernel oil with different melting points such as 8 degrees, 10 degrees, 14 degrees, 18 degrees, 24 degrees, 33 degrees, 44 degrees, 55 degrees, etc. This fractionation process can also be used for the fractionation of tallow, deep-sea fish oil, cottonseed oil, rice bran oil and other oil products, which greatly increases the added value of oil products and increases the economic benefits of enterprises.

Dry fractionation method of palm oil
Dry fractionation is one of the most economical methods. It refers to the method of slowly cooling the oil in the dissolved state to a certain extent without adding any solvent, and then filtering the crystallization to separate the solid ester.
Palm oil is a semi-solid state at room temperature, and its saturated acid and unsaturated acid each account for about 50%. Palm oil is dissolved into a liquid state by steam heating before processing. Generally, palm oil is heated to about 70°C before crystallization to destroy all existing crystals.
Cooling and crystallization
The key to the dry fractionation process is cooling and crystallization. Under stirring and circulating water cooling, the cooling process is controlled by setting the temperature difference between the oil and cooling water and the cooling time to form crystal nuclei and grow slowly. When the required temperature is reached (depending on the quality of the soft fat that is finally required, generally 20°C), stop cooling.
The selection of filter equipment also has a greater impact on the yield of liquid oil. Diaphragm filters have been widely used in the palm oil fractionation industry. This is because the soft fat extracted by the diaphragm filter has a higher yield (70% to 75%), and the hardness of the hard fat is also higher.
