Soya/ soybean oil refinery plant
Henan Doing Company’s soybean oil refinery plant can be divided into three types according to different capacities.
1-20tpd small soybean oil refinery plant(batch type)
20-50tpd medium soybean oil refinery plant(semi-continuous type)
30-1000tpd large soybean oil refinery plant(full-continuous type)
Three types soybean oil refinery plants
About the differences of three types soybean oil refinery plant, please read this passage-- edible oil refinery plant.
Soybean oil is extracting from soybean, in which there are 16-24% oil. Because the oil content of soybean is low, most soybean oil manufacturers choose solvent extraction method to produce soybean oil.
However, the soybean oil getting from solvent extraction method must be sent to soybean oil refinery plant, where crude soybean oil will finished degumming process, neutralization process, bleaching process and deodorization process, then becomes refined soybean oil.
Why it is so important for us to refine crude soybean oil by soybean oil refinery plant? Experts found that crude soybean oil includes large quantities of impurities, such as gums, pigments, phosphatides and free fatty acid (FFA), among which some are harmful to our health.
When using crude soybean oil to cook, we can smell choky smoke, which is also influenced by impurities in soybean oil. Phosphatide not only make soybean oil cloudy and dark, but when cooking, it produces a lot of foam and black precipitate. And the higher the content of free fatty acid (FFA) is, the lower the soybean oil smoke point is. Through deodorization process of soybean oil refinery plant, the low carbon chain can be removed altogether, then the smoke point of soybean oil can be controlled above 215℃.
What’s more, people pay more attention to health now, and are strict with the quality of edible oil. So building a soybean oil refinery plant is necessary for soybean oil manufacturers.

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.
During decolorization, unwanted pigments are adsorbed physically and oil will become much clearer.
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.
