1,Why should we need to refine the edible oil?
The edible oil making line include 3 steps:
1),pre-press;
2),solvent extraction;
3),Oil refinery.
the plants oils from first 2 steps always have some undesired impurities, such as FFA( Free Fatty Acid), so, The foremost aim of refining process is removing extra free fatty acids and preventing the oils from oxidation, but not only the FFA, it also removes the unwanted impurities, color and odor which may have a negative impact on the taste, odor, and appearance of the oil. The oil after refinery process is thinner without FFA, colorless and odorless, and also, it is good for human health and easy to storage.
2, Edible oil refinery process
Two methods:1,chemical refining 2, physical refining
Processing Capacity: 5~5000TPD
Application Range: various crude oil
oil refining is a complicated process not only include physical andchemical refining.depending on different physical and chemical characters of the oil and accompaniment, separate oil and impurities with the help of acid, alkali, high temperature process, ect.
Main oil refining process :
(1). Intermittent Refining Process

Main oil refining process :
(1). Intermittent Refining Process
Suitable for small scale oil refining plant.
Major process: degumming, deacidification, bleaching and deodorization.
Major process: degumming, deacidification, bleaching and deodorization.
(2). Semicontinuous Refining Process
Major process: degumming, deacidification, bleaching, deodorization.
(3). Continuous Refining Process
Suitable for large scale oil refining plant.
Major process:degumming and alkali refining,deacidification, water washing, drying, bleaching, filtration,deodorization.
3, Edible oil refinery flow :Major process:degumming and alkali refining,deacidification, water washing, drying, bleaching, filtration,deodorization.
Features of the twoo methods of the edible oil refinery
1,Chemical Refining
The refined oil is consistent and stable.
Excellent adaptability and less requirement to oil quality.
Less bleaching earth is needed.

Less bleaching earth is needed.
Physical Refining
High oil refining rate, less oil loss.
No waste water discharged.
Especially suitable for oil of high acid value, low gum content.
More FFA distilled out.
