Soybean oil refinery plant

 Why is the soybean oil refinery plant necessary for soybean oil producers? Soybean oil is indispensable in our daily life, no matter what kind of food you make. Especially in China, our diet culture can go back to thounds of years ago, and soybean oil quality will directly influence the food flavor. Thus high quality soybean oil is definitely important. It is said if soybean oil has not been refined, there is full of impurities such as gums, pigments, waxes, phosphatides and free fatty acid (FFA), among which some are harmful to our health. In a word, soybean oil refinery plant is essential, which can remove harmful substance and offer us the first or second grade edible soybean oil.
Soybean oil refinery plant is the third workshop in the whole soybean oil production line. The other two workshops is soybean pretreatment workshop and soybean oil solvent extraction workshop.

Craft flow for soybean oil refining process:

Crude soybean oil → degumming and deacidification → decolorization → deodorization → refined soybean oil.

Soybean oil refining process

Four main steps of soybean oil refining process:

1. Crude soybean oil degumming:
In this step gums in crude soybean oil are removed by hydration with the help of phosphoric acid.
2. Deacidification (neutralization):
In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Decolorization:
During decolorization, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization:
Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.

In general, soybean oil refinery plant is divided into 3 types, batch type, semi-continuous and full-continuous soybean oil refinery plant, the difference of which is capacity. If your capacity is 1- 30tpd, you can choose batch type soybean oil refinery plant. If your capacity is 20 -50tpd, you can choose semi-continuous soybean oil refinery plant. If your capacity is 50 - 200tpd, you can choose full-continuous soybean oil refinery plant. What’s more, our engineers can help you design and install soybean oil refinery plant according to your capacity and requirements.
