Problems solved by technology

[0006] In the first issue of 2002, the title "Theory and Practice of Grease Degumming" published on the "China Oils and Fats" magazine described the method of degumming the fragrant peanut oil by using filter paper as a semi-permeable membrane. This method saves energy consumption to a certain extent. , but the separation rate is not high
[0007] The application of inorganic membrane separation technology in oil degumming process has not been reported

Abstract

The vegetable oil degelatinizing process features that inorganic ceramic film is used in cross current filtering of mixed vegetable. The said process may be used in replacing traditional two steps of hydrolysis to degelatinize and caustic refining, and this can reduce power consumption, lower production cost, reduce waste water produced in refining, protect environment and save decolorizing adsorbent.

Description

technical field [0001] The invention relates to a method for degumming vegetable oil. Background technique [0002] The traditional vegetable oil refining method is chemical refining, which generally includes degumming, neutralization (alkali refining), decolorization, deodorization and other processes, and some oils also need to be dewaxed. Degumming mainly removes colloids such as phospholipids, proteins and sugar esters; neutralization is to neutralize free fatty acids in oils by alkali; decolorization generally uses activated clay to absorb pigments in oils; deodorization is to remove fats in oils by steam distillation. Flavor substances. [0003] The traditional oil degumming process is hydration degumming and chemical degumming. The disadvantage of hydration degumming is that the efficiency of hydration degumming is generally lower than 90% because oil contains a certain amount of non-hydratable phospholipids. Although chemical degumming can better remove the colloi...
