Crude cooking oil, whether pressed or extracted, must be refined before it can be eaten. If the oil contains more impurities, it will be harmful to human health. These impurities mainly include water, free fatty acids, gums, etc., which can easily deteriorate the oil and damage human health. Refined oil can be stored for a long time. So how to solve the problem of low quality cooking oil? Our refining machine can solve this problem very well.

Refining process mainly includes four steps of degumming, deacidification, decolorization, and deodorization.

Degumming: Add food-grade phosphoric acid to crude oil to convert non-hydratable phospholipids into hydratable phospholipids, add water to make colloids enter the water phase to precipitate and remove.

Deacidification: The degummed oil is added with food-grade alkali for acid-base neutralization reaction, and then removed by heating and natural sedimentation.

Decolorization: When the oil is heated to a certain temperature, a certain amount of activated clay and activated carbon are added to the neutralized oil to physically adsorb the pigment in the oil.

Deodorization: Evaporate unpleasant odors and moisture in a high-temperature vacuum environment to obtain high-quality refined oil.

Our refining machine types can be divided into batch type cooking oil refining machine, semi-continuous cooking oil refining machine and full continuous cooking oil refining machine. Like batch type cooking oil refining machine, it is suitable for small tonnage, flexible operation, low investment, and suitable for the replacement of various oil products. Semi-continuous refining and full continuous refining are more suitable for large tonnage and stable product quality.It is also possible to customize the machine according to the customer's local national standard.
