Step sunflower oil refining process

Step sunflower oil refining process, after crushing method or leaching resulting sunflower oil contains impurities, which requires the use of specialized equipment for its refining refining purification. Because there is a lower gross impurities in the oil sunflower oil natural conditions, but some things in the production orstorage when produced. Its root causes are different, so the refining according to their different conditions in several steps to carry out. 
First, degumming, refining degumming is the first step, only the degumming process comprising the hydrationof crude oil, a number of impurities, such as: phospholipids, and protein in the dry gum dissolved in the oil, upon hydration can not be dissolved in an oil this is the principle of hydration unglued, however, there are still some gum in oil, which requires them to be removed after acidification hydration.

                 
This alkali refining is neutralized with caustic soda and the free fatty acids in the oil, so that the saponification.Stop after saponification of the free acid is dissolved in water, and thus can be precipitation or centrifugation.After removal of the free acid, and can not be completed because of this phase must go unless hydratedphospholipids. 
Step sunflower oil refining process, bleaching process with suitable absorbent material to remove pigmentssuch as carotenoids, chlorophyll and so on. Bleaching has become a more important process, which is before the deodorization to remove residual phospholipids, as well as oxides of metal ions last pass. Furthermore, the removal of other impurities is very important, because it directly affects the flavor and organoleptic deodorized oil oxidation characteristics. 
In most cases, the last step of deodorization is the most refined, its main purpose is to remove the influence ofthe odor of oil, the taste substances in the physical refining, can also remove the free acids. Despite the different type of technology, but the purpose is always a: to ensure full contact of oil with water vapor, and achieved the desired results. 
This is the step of sunflower oil refining process, hope we can learn from. Grain and Oil Machinery Co., Ltd., Zhengzhou First production and operation of various types of refined oil equipment, welcome to visit the factory procurement.
