Dingsheng Machine: Advanced Oil Refining Solutions – Degumming Process
Date:Nov 4th, 2024
Degumming is a vital step in oil refining, using physical or chemical methods to remove gummy impurities from crude oil. This purification process primarily targets phospholipids, proteins, carbohydrates, resins, and other colloidal substances. Among these, phospholipids are the main impurities, causing dark coloration, cloudiness, and unpleasant taste in oil. They also absorb moisture, leading to rancidity and a decline in oil quality.
Why is Degumming Necessary?
Gummy impurities negatively affect the stability of oils and complicate subsequent refining processes. For example:
Alkali Refining: Without degumming, oils form emulsions, increasing operational difficulty, refining losses, and auxiliary material consumption.
Decolorization: Oils with impurities consume more adsorbents and compromise decolorization efficiency.
Thus, degumming is the first step in refining, laying the foundation for deacidification, decolorization, and deodorization.
Working Principle of Degumming
Phospholipids and other impurities in oils are hydrophilic. The process involves stirring hot crude oil with a specific amount of hot water or an electrolyte solution, such as phosphoric acid or saltwater. After a reaction period, the impurities aggregate, precipitate, and are removed from the oil. Water degumming primarily eliminates hydratable phospholipids along with minor quantities of proteins, glycerides, and mucilage.
Methods of Degumming
Several methods are employed in oil degumming:
1, Water Degumming: The most common method in edible oil refining. Removes hydratable phospholipids and some non-hydratable phospholipids. Residual non-hydratable phospholipids are removed via acid degumming.
2, Acid Degumming: Uses acids to target and eliminate non-hydratable impurities.
3, Alkali Refining Degumming: Combines degumming with neutralization for improved efficiency.
4, Adsorption Method: Uses adsorbents to capture impurities.
5, Enzymatic Degumming: A modern approach leveraging enzymes for selective impurity removal.
