Oil
Refining
Capacity:
1)Small Plant of 0.5-30TPD
2)Big Plant of 30-100TPD
Principle:
There’re twy of refining:physical & chemical.
Physical Refining:
This means removing gum inoil during degumming process in
special method and removing FFA during deodorizing process
with steam.
Features:
1. Less oil losss and high refining ratio;
2. No waste water in the process of production;
3. More FFA is distilled out;
4. Moresuitable for oil with high acid value and low gum
impurity
Chemical Refining:
This means removing FFA in a chemical way (acid-base neutralizaion).
The produced gum and soapfoot are separated by centrifuges.
Chemical refining has following features:
1. Excellent adoptability and less requirements to oil quality;
2. The final oil quality is consistent;
3. Less clay is added into compared with pahysical refining.
Refining process can remove phospholipid, FFA, pigment,
off-flavor and other impurities. It includes the following
sections: Dugumming, Deacidifying, Bleaching, Deodorizing
and Dewaxing.
