Soybean oil refining process

Batch soybean oil refining process is quite suitable for small capacity vegetable/edible oil making plant, Batch soybean oil refining process capacity ranges from 1TPD to 20TPD. These batching stages are Degumming,Neutralizing, Decolorization and Deodorization.

Main Refining Processes for Batch soybean Oil :
1. Degumming Process of soybean oil refining process :Some impurity, such as Phospholipid, gum, and protein, can be dissolved into oil when there is no water, but once there is water in oil, these impurities can be dissolved into water. So, in degumming section, we use the hot water to wash crude oil for two-three times to remove these impurities.

2. Neutralizing/Neutralization Process of soybean oil refining process :The crude oil is fed into the neutralizer and mixed with small amounts of degumming agent such as phosphoric acid to help remove gums.Free fatty acids are removed from the oil by adding caustic soda and heating it at 60˚ then stirring the mixture. Heating helps caustic soda to react with the fatty acids to form the soap material. Once the soap material settles in the neutralizer machine, it is collected with soap pans while the oil is washed with water to remove any traces of soap or any alkaline particles.

3. Decolorizing Process of soybean oil refining process:The neutralized oil requires bleaching to get rid of colors. This is done by adding the oil in a bleacher machine whereby it is heated to remove any moisture it might have and then mixed with earth bleach and activated carbon. These two properties absorb any colors after which the oil is passed through a filter to separate oil from earth bleach and carbon. The result is golden light oil.

4. Deodorizing  Process of soybean oil refining process:The golden light oil has unpleasant odors which result from materials such as aldehydes, ketones, tocopherols and phenols among other odiferous elements. Deodorizing process helps remove these odors by adding the oil in the deodorizer and heating it above at very high temperature ranging from 110˚ to 220˚ and under very high vacuum. This process helps get rid of all odors.
