According to different capacity and technology, the edible oil refinery can be divided into three ways which including batch edible oil refinery, semi-continuous edible oil refinery and continuous edible oil refinery. Batch oil refinery is the simplest technology, so the cost of it is also smallest.

Before it is made ready for human consumption, cooking oil undergoes through a number of different processes in a cooking oil refinery plant. Simply defined, refining is the process of removing impurities which may be present in the cooking oil. Such impurities include phosphatides, free fatty acids (FFA), waxes and gums. The refining process is also necessary since it gives the final product a uniform color by getting rid of all the coloring pigments that may have been present. It also helps in the removal of bad smell that may be due to the presence of odiferous matter present.

Features of batch edible oil refinery plant:

1.The extra boiler is not needed, so batch edible oil refinery has wide scope of application.
2.The combination of short mixing and long mixing ensure the quality of washing.
3.The leaf filter is used in the decolorization section. The advantages of it is simple operation, less worker, oil residues is less in the white clay.
4.Batch edible oil refinery can be used to refine various edible oil, after changing the temperature of water.
5.The quality of final oil is stabilize.

Main equipments of batch edible oil refinery :
Neutralization pot: to move the acid in the edible oil and washing the oil.
Decolorization pot: to move the pigment in the oil.
Deodorization pot: to move the pungent taste in the cooking oil.
Conductive oil stove: It is used to provide the heat for the whole process.
Vacuum pump: The function of it is to provide vacuum for decolorization and deodorization.
Air compressor: It will dry the white clay after absorb the pigment in the oil.
Steam generator: To generate the steam for the deodorization pot.
