Oil degumming and solvent extraction technology:
Crude oil belonging to the colloidal system in which the phospholipids, proteins, glycosylation phlegmatic and diglycerides, etc., because the triglyceride composition of sol gel derived insoluble impurities called fat. Glue insoluble impurities exist not only affect the stability of oils and fats, and the impact and depth of oil refining process effect processing. For example grease alkali refining process is easy to form the emulsion, increasing the difficulty of the operation, increased consumption of oil refining losses and auxiliary materials, and reduce the quality of soap feet; in bleaching process, will increase the consumption of adsorbents , reducing bleaching effect; not degummed oil can not be physical refining and deodorization operation can not be deep processing. Therefore, you must first removal of crude oil refined gum insoluble impurities.
Application of physical, chemical or physical and chemical methods for removing hair oil soluble impurity removal process called degumming. Degumming methods are hydration degumming, refining degumming acid adsorption unglued, thermal and chemical reagents poly unglued unglued, etc., the oil industry is the most widely hydration degumming and acid refining unglued. The refined edible oils to use more hydration degumming, strong acid is used in industrial oil refining unglued refined.
