Advanced oil fractionation equipment /palm oil fractionation plant Introduction

Oil is a compound of many kinds of glycerol triester. Oil fractionation is the process of separating oil into different glycerol triesters at certain temperatures. Oil fractionation is a physical process, with no expensive or hazardous chemical additives, no chemical reaction, no loss and waste water. Oil fractionation is applied in processing palm oil, sunflower oil, cottonseed oil, rice bran oil, fish oil, lard oil, chicken oil etc.

1) Cottonseed oil fractionation
Cottonseed oil is one of the largest oil types, whose fatty acid is composed of 20%~22% palmitic acid, 30%~35% oleic acid, 40%~45% linoleic acid. The melting point of cottonseed oil is 10~15.6 °C. As the high-grade edible oil, cottonseed oil is not widely used in winter because of its easy turbidity caused by higher melting point, so its price is also low. By fractionation, liquid and solid oil can be obtained, which can increase oil' added value and edibility.
2) Animal oil fractionation, such as fish oil, lard oil, chicken oil etc.
With the fractionation, separate the white and transparent hydraulic oil from animal oil. The Cholesterol in fractionated oil is 50% less than that in crude oil, which greatly improves the nutritive value of animal oil and has a very high economic value.
3) Separation of mixed fatty acids
According to the carbon chain length of fatty acids, separate short carbon chain (C12), medium carbon chain (C14) and long carbon chain (C16, C18) by vacuum distillation, and then separate the saturated fatty acid from the unsaturated fatty acid. Owing to the little boiling point differences between them, they can't be fully separated and also will has high production cost. Our company uses dry fractionation to separate the mixed fatty acids into various fatty acids of different melting point and application.
