Sunflower oil refinery plant
Because of high wax content, sunflower oil refinery plant has one more process than other vegetable oil refinery plant. So except for degumming, deacidification, decolorization, deodorization, sunflower oil dewaxing process should be added after deodorization process in sunflower oil refining process.
Sunflower oil is one of the world's traditional oils. Rich in linoleic acid (54% to 70% of total fatty acid content) and oleic acid (about 39%), the nutritional value is higher, but the crude sunflower oil contains trace amounts of wax (about 0.10%) and oxoacid, affecting quality and storage stability. By dewaxing, sunflower oil will still remain transparent and clear even in winter.
About sunflower oil dewaxing process, there is detailed introduction, please read-- Dewaxing process.

Main process of the sunflower oil refinery plant:
|Main process||Functions of each step|
|1.Crude sunflower oil degumming||In this step gums in crude sunflower oil are removed by hydration with the help of phosphoric acid.|
|2.Deacidification (neutralization)||In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap.Additional impurities are also removed by adsorption on soap.|
|3.Decolorization||During de-colorization, unwanted pigments are adsorbed physically and oil will become much clearer.|
|4.Deodorization||Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.|
|5.Dewaxing (necessary for sunflower oil)||Sunflower oil dewaxing machine reduce wax content in sunflower oil, which help increase edibility of sunflower oil.|
