20-50tpd edible oil refinery production machine

Why edible oil need refining?
The crude edible oil obtained from oil expellers or solvent extraction contains impurities such as phosphatides, free fatty acids (FFA), pigments, off-flavor, etc. Oil Refining is a series of process to remove these impurities. After refining, the flavor, color and smell of edible oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased. We provide 1-20tpd batch type edible oil refinery plant ,20-50tpd semi-automatic edibel oil refinery plant and 50-500tpd fully edible oil refinery plant for you. Besides, 1-5T/D edible oil refining line and 20T/D edible oil refining line are also available.

Usually the edible oil refinery production machine includes three parts: deacidification, decolorization and deodorization. For the palm oil refinery, it also need the crude palm oil fractionation part to get higher quality palm oil. In the process of rice bran oil refinery machine, sunflower oil refinery machine and corn germ oil refinery machine, it needs winterization part to move the wax in the crude oil. We can also provide waste cooking oil refining machine.

Main processes of 20-50tpd edible oil refinery production machine :

edible oil refining machine 1. Degumming and deacidification section:

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.
edible oil refining machine 2.Decoloration section

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.
edible oil refining machine 3.Deodorization section

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.
edible oil refining machine 4.Filtering section:

After getting the deodored oil , in order to get the most purified cooking oil , we usually using the SS safety filter to filter refined oil once again.
edible oil dewaxing machine 5.Dewaxing section:

Because there is some wax in the sunflower oil , corn oil, rice bran oil , etc. , if you want to get the first grade cooking oil , de-waxing machine is required. It depends on the customer.
palm oil fractionation machine 6.Fractionation section:

Refined palm oil should go through fractionation process to separate solid phases (Stearine) and liquid phases (Olein). It is achieved by thermo-mechanical means. Fractionation can greatly maximize the value of products.The typical fractionation process of palm oil mill is controlled cooling, crystallization, and filtering.

After above steps , the final product is refined edible oil ,which can reach the level of consumption!If you want to know more information about 20-50tpd edible oil refinery production machine ,please feel free to contact us!
