Edible Oil Refinery Process Flow Diagram

1. Degumming
The purpose of degumming is to remove impurities such as phospholipids, gums and proteins etc. There are several methods as follows: water degumming, acid degumming, special degumming etc.

2. Neutralizing
The purpose of neutralizing is to remove free fatty acid in oil by using caustic soda while removing impurities such as phospholipid, pigments, metal ions, peroxide etc. by use of soapstock.

3. Bleaching
Bleaching is the process operation which removes colouring matters by mixing bleaching earth with oil under controlled conditions of temperature. After proper mixing with bleaching earth for a specific residence time, the mixture is finally pumped into leaf filters with stainless steel mesh elements followed by polishing filtration.

4. Deodorizing
Deodorizing is the final stage in oil refining in order to remove odoriferous material, free fatty acids and other undesired minor components by steam distillation under condition of high temperature and vacuum to produce a bland oil with a good shelf life.

5. Dewaxing
Through automation system, combined with crystallization curve (time-amount of crystallinity) of different oil, crystals in oil grow and finally can be separated by filtration to obtain dewaxed oil.
