This article is only an overview of production processes, detailed information, please enter the double spike machinery official website: www.ssyzjx.com oil refining equipment, animal oil refining equipment, fish oil refining equipment, refined oil refining equipment lard winter of fractionation equipment: oil is by a variety of lipid mixture consisting of three Gan, at a certain temperature, the process of separating the oil into different components is the triester Gan fractionation. Grease Fractionation is a physical process, not practical expensive or dangerous chemical additives, no chemical reaction, no loss, no sewage. Fractionated oils such as sunflower oil fractionation, cottonseed oil, rice bran oil fractionation, fish oil, lard, chicken fat and other animal fats fractionation and so forth. Cottonseed oil fractionated cottonseed oil is one of the bulk oil, fatty acid composition Palmitic acid 20% -22%, 30% -35% of oleic acid, linoleic acid, 40% -45%; cottonseed mp 10-15.6 ℃. As a senior edible oil, cottonseed oil, high melting point easily muddy in the winter use is restricted, low prices. By fractionation to obtain liquid oil and solid oil, may increase the added value and edible oils. Fractionation fish oil, lard, chicken fat and other animal fats using the animal oil fractionation white, transparent liquid with a rich meaty animal fats points raised, the resulting oil is lower than the original animal fats cholesterol levels by 50% greatly enhance the nutritional value of animal fat, with high economic value. According to the separation of mixed fatty fatty acid carbon chain length, vacuum distillation of short carbon chain (C12), the carbon chain (C14) and long carbon chain (C16 / C18). However, isolated from unsaturated fatty acids with saturated fatty acids, since the boiling point difference between them is small, can not be completely separated by distillation and a high production cost. The adoption of the double spike dry fractionation, speaking mixed fatty acids separated into different uses different melting fatty acid products.
