Palm oil fractionation is a process to separate the palm oil into low melting point liquid phase (soft fat) and high melting point solid phase (hard fat) by controlling the cooling crystallization process. Fractionation can divided palm oil in three components: palm stearine, palm olein and palm midfraction. The stearin is mainly S3, β-POP, β-PPO triglyceride. The mid-fraction is mainly β-POP. And the soft fat is mainly SU2 and U3 glycerides. The melting point of stearic is generally 50 ℃ and it is about 24 ℃ for soft fat.

Application of Palm Oil Fractionation
A-Palm Stearine: It is suitable for making margarine and shortening. It will not result in slow crystallization, greasy and post-hardening, and greatly improve the plastic range of fat. For example, 70% of the stearin and 30% of rapeseed oil are combined with good oxidation stability, being good bread oil before ester exchange and good frying oil after ester exchange.
B-Palm Olein: Soft fact is excellent frying oil.
C-Mid-fraction: The melting point of middle part is narrow and close to human body temperature, but can be used as cocoa substitute.

Related introduction of palm oil fractionation plant:
Palm oil fractionation plant uses mechanical separation of liquid oil from solid fractions of certain oil and fats. Palm oil fractionation plant can greatly maximize the value of products.
Dry type palm oil fractionation plant is the most economical fractionation without adding any solvent. The oil in dissolved state is cooled slowly to a certain degree, passing through filtration to separate crystals and precipitate solid ester.
The whole palm oil fractionation process is controlled by fully automatic PLC. The control of the crystallization process is realized by controlling the temperature of the cooling water in the crystallization tank coil and cooling water temperature. The cooling water temperature is controlled by a PLC based temperature sensor. From the computer display, the cooling water temperature curve and palm oil crystallization temperature curve can be observed visually, hereby ensuring smooth, steady decline of the curve, and get the ideal crystallization curve. The palm oil fractionation process is simple, easy to operate, low in steam consumption, no environmental pollution, and can get satisfactory results.
