The main process of fully scale sunflower oil processing plant is shelling, pre-pressing, solvent extraction, oil refining and oil filling. (Extract oil after dehulling can reduce the wax content of final oil.) Complete Sunflower Oil Processing Steps Undertake 1~100ton/day Sunflower Oil Production Line with Cusotmized Business Plan
How is sunflower oil produced?
Through selective breeding and manufacturi Sunflower oil production has the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extraction of crude oil from these seeds and then further refining the oil obtained before packaging. A volatile hydrocarbon like hexane is used as a solvent to extract the oil.
How hexane is used in sunflower oil extraction?
Which is where solvent extraction comes to the rescue. Solvent extraction is the part of the sunflower oil making process in which almost every last drop of oil is extracted from the sunflower seeds. Hexane is the most widely used solvent for this. The process begins with the pouring of hexane over the leftover cake from expeller pressing.
Are there different types of sunflower oil seeds?
Several varieties of sunflower oil seeds have been developed by standard plant breeding methods, mainly to vary the amounts of oleic acid and linoleic acid which, respectively, are the predominant monounsaturated and polyunsaturated fats in sunflower oil. Sunflower oil is a rich source of vitamin E (tables).
