Batch type soybean oil refinery machine
Batch type soybean oil refinery machine is quite suitable for small capacity soybean oil refinery plant, generally for 1-20 tons per day. Among them, 1-2tpd mini soybean oil refinery machine is most popular in our customers because of its low cost and easy to operate.
Batch type soybean oil refinery machine designed by Henan Doing Company
In batch type soybean oil refinery plant, the soybean oil refining process includes degumming, neutralization, decolorization and deodorization.
Soybean oil refining process flow chart
1. Degumming process of batch type soybean oil refinery machine:
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. Neutralization Process of batch type soybean oil refinery machine:
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. Decolorization Process of batch type soybean oil refinery machine:
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 batch type soybean oil refinery machine:
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.
