edible oil refining process

The edible oil refining process mainly includes degumming,deacidification,decolorization and deodorization.It can be used to process various kinds of crude oil,such as crude soybean oil,crude  peanut oil,crude palm oil etc.Through the edible oil refining process,we will get standard edible oil.There are mainly two methods of edible oil refining process:chemical and physical method.

Types of edible oil refining process:

Batch type refinery,1-2-3-5-10TPD

Semi-continuous type refinery,10-50TPD

Full continuous type refinery,above 30TPD

Main workflow of edible oil refining process:

Crude oil--Degumming--Deacidification--Decolorization--Deodorization--(Winterization/Fractionation)--Standard edible oil

1.Degumming:this is the most important section of edible oil refining process,adding the water(there is little P-acid in water)to remove the gum.

2.Deacidification:using alkali like(NaOH)to neutralize FFA in edible oil,during this edible oil refining process,it will produce soap stock,then separating it from the oil.

3.Decolorization:because there is pigment in crude oil,the oil color is dark.In order to lighten oil color,we need to use the white clay to absorb the pigment away,then using vibrate filter to separate the waste clay.If you want to get light color oil,you need to add more white clay.the oil color can be controlled by clay amount.

4.Deodorization:generally speaking,the crude oil smell not good,it will affect oil storage and price.So we usually use the direct steam to take odors.Meanwhile,there is about 0.5% water content in refined oil,because the high temparature in the deodoration pot,dehydration is also finished.After that,the final oil will be refined once again through safety filter.This is the final edible oil refining process.
