The process of crude oil refining.

1. Degumming and deacidification:

The gumming is removed by phosphoric acid and hot water.

There are two ways to remove the acid in crude oil. One is chemical way, the other one is physical way. In 1-10TPD small scale edible oil refining plant, the chemical way is used. It mainly use NaOH to react with acid.

2.Decolorization:

The purpose of decolorization step in small scale edible oil refining plant is to remove color pigments contained in oils. It mainly use white soil adsorption decolorization methord.

3.Deodorization:

The function of this step is to remove disagreeable flavor and odors that are naturally present or created during processing under high temperature. Deodorization tank is a stainless steel sealed container, including heating coil and central steam jet circulating pipe.
