Oils and fats are a mixture of triacylglycerols with different melting points.Fractionation means to separate them through different temperature.

The fractionation technology developed by OCEAN can be used for high melting point oil, such as palm oil,cottonseed oil, lard, tallow, chicken oil, fish oil, etc.

By utilizing advanced crystallization equipment, filtration and pressing technology, and precise automatic temperature control technology, palm oil products with different melting points, such as 6℃, 8℃, 10℃, 14℃, 18℃, 24℃, 33℃, 44℃ and 55℃ can be obtained, The entire process is controlled by computer and operates fully automatically.

Fractionation of fish oil, lard, chicken oil, etc.
Liquid oils in animal oils and fats can be separated by fractionation, which has a low content of saturated fatty acids, high nutrition value, good flavor and good economic benefits

Fractionation of cottonseed oil
Cottonseed oil is one of the major oils, with its fatty acid composition including 20-22% palmitic acid, 30-35% oleic acid, and 40-45% linoleic acid.The melting point of cottonseed oil ranges from 10-15.6℃.As a high-grade edible oil, cottonseed oil has a relatively high melting point, which can cause it to become cloudy and limit its use in winter, By fractionation, liquid oil and solid oil can be obtained, which enhances the added value and practicality of the oil

Oil concentration rich in AA, DHA, EPA,a-linolenic acid
Through fractionation, the high-melting-point components are separated from the low-meltingpoint components rich in polyunsaturated fatty acids,resulting in a low-melting-point, high-nutritionalvalue liquid oil that is rich in polyunsaturated fatty acids such as AA, EPA, and DHA, with stable quality and transparent color.

Separation of fatty acids mixture
Based on the length of the fatty acid carbon chains,vacuum distillation separates short-chain, medium-chain, and long-chain fatty acids. However,separating saturated fatty acids from  unsaturated fatty acids is challenging because their boiling point differences are very small, making complete separation by distillation difficult and costly. Ocean uses dry fractionation to separate mixed fatty acids into products with different melting points and functions
