Why Does A Centrifugal Filter Need Salt Water?
Time:Tue-03-23 hits:
In the filtration of edible oil equipment, there are two kinds of media filtration and no media filtration.
There is medium filtration, that is, cloth filtration, which often does not require the addition of salt.
Centrifugal filter belongs to no medium filtration, need to add salt water.
Today I will tell you why the centrifugal filter adds salt water.
The pressed crude oil belongs to the colloidal system. Colloidal impurities include phospholipids, proteins, mucous, and glycylglycerin diacetate.
The presence of colloidal impurities affects the stability of grease.
For example, hair oil is easy to foam, bruising pot, smoke and so on.
The crude oil needs to be stripped of gelatinsoluble impurities. Cooking oil is often degummed by hydration.
Hydration degumming: Based on the hydrophilicity of colloidal impurities such as phospholipid, a certain amount of aqueous electrolyte solution such as hot water or salt is added to hot crude oil under stirring.
The hydrated phospholipids will absorb other glia in the oil, causing the particles to grow larger and then aggregate with each other, gradually folding out and suspending in the oil phase.
Due to the increase of water absorption, the expansion of these substances will also increase, and the small colloidal particles attract each other, and eventually condense into large micelles, which lays a solid foundation for centrifugal separation.
Centrifugal filter through high speed rotation, oil and oil residue separation.
