Cottonseed oil is a new kind of oil. Most of the common cottonseed oil in the market is extracted by screw press, and then refined by cottonseed refining equipment. Studies have found that eating refined cottonseed oil is of great benefit to the human body. Therefore, not only the pressing process is important, but also the refining process. At present, most people consume refined oil. This not only retains the nutrients in the oil, but also makes it easier to store and less likely to deteriorate. Refining is also an integral step in the oil extraction process. Do you know how cottonseed oil is refined, what are the processes? What is the purpose of these steps? Next, Benteng Machinery will introduce the cottonseed oil refining process.
The general process of cottonseed oil refining: crude oil – degumming – deacidification – bleaching – deodorization
Cottonseed oil refining steps
1. Crude oil, also known as crude oil, is usually used for processing into edible cottonseed cooking oil.
2. Degumming: used for neutralizing water washing and acid removal.
3. Deacidification: Deacidification is to remove the crude oil contained in the process of removing free fatty acids. The crude oil is deacidified by steam distillation, alkali refining, solvent extraction and other methods.
4. Bleaching: that is, decolorization, which is used to remove other colors in the oil, so that the color of the finished oil looks good, and the finished oil achieves a clear and translucent feeling. The color of finished cottonseed oil is usually brownish yellow.
5. Deodorization: It is used to eliminate the smell of oil at high temperature and the peculiar smell of water vapor.
