Sunflower seed oil refining process

Sunflower seed oil refining process, the process of refining what it was like, what are sunflower seed oilrefining process, the refining process need to pay attention to what the problem then, let's talk about the lookbelow. 
The press or through leaching of crude oil filter, hydration, alkali refining, sour refining, bleaching, deodorization processes, removal of all kinds of solid impurities, colloidal impurities and fat-soluble impuritiesequipment.

                  
History barrel oil refining technology development has long remained at the original precipitation (vegetable oil) or exercise method (animal fat) levels. Until the 19th century the use of chemical oil refining technologywas first put forward, and began the application in production equipment are used in the batch tank mixingdevice. 1923 Hapgood and Mayno first proposed refined vegetable oil by centrifugation. 
Sunflower oil refining process are hydrated (unglued), alkali refining (deacidification), bleaching, deodorizationor desolventizing, dewaxing and degreasing equipment. According to the degree of continuous production process is divided into batch, semi-continuous and continuous three categories. 
The purpose is to remove the oil refining crude oil in the mechanical impurities, colloidal impurities(phospholipids, free fatty acids, proteins, polysaccharides gum), pigments (chlorophyll, carotene), odorsubstances and waxy, water and so on.
