Raw materials of cooking oil refinery plant
Different raw material,the refinery process is little different.such as for peanut,soybean,cotton seed,sesame,castor,rapeseed etc,the refinery process has four steps:degumming,deacidification,decolorization and deodorization.
For corn germ,rice bran,sunflower seed,palm oil,the refinery process has five steps:degumming,deacidification,decolorization,deodorization and dewaxing(also called fractionation for palm oil).

There are three types of refinery plant,decide by different capacity:

1.Batch type refinery plant: normally the capacity for this type is less than 20TPD.the refinery process of this type is refined one batch by one batch.

batch type refinery plant

2.Semi-continuous type refinery plant:normally the capacity for this type is 20-50TPD.the refinery process of this type is parts batch by batch,and parts continuous

3.Fully-continuous type refinery plant:normally the capacity for this type is above 30TPD.the refinery process of this type is fully continous,no need stop in the refinery process.

1. Degumming and deacidification in cooking oil refining process
Degumming is using phosphoric acid ,water to react crude oil and then separate phosphatide from oil. But in order to reduce more phosphatide, after enough phosphoric acid treatment, adding alkali inside oil to neutralize free fatty acid , and washing before gum separation , this process is called deacidification. Here the byproduct is soap stock which can be used for making soap.
Main cooking oil refining equipment : alkali bin, oil refining kettles

2. Decoloration in cooking oil refining process
Decoloration is using clay to bleach oil , in this step, clay will absorb dark colorant of oil .The quantity of clay is depending on the deepness of crude oil. After bleaching , used clay will be screened out by vibrating screen.
Main cooking oil refining equipment : decoloring kettle, vibrating screen, pumps

3. Deodorization in cooking oil refining process
This step is to remove some unnecessary odors from crude oil. Normally for chemical oil refining ,it adopts plate deodorizing tower using high temperature steam to remove odors.
Main cooking oil refining equipment : deodorizing kettle, pumps
After above steps , the final product is refined cooking oil ,but some cooking oil need more treatment such as dewaxing for sunflower oil, fractionation for palm oil etc.
