Edible Oil Refinery Process
Actually edible oil refinery is classfied into physical refining and chemical refining, and we will introduce the chemical refining method. The complete edible oil refining process is composed the following sections which are Degumming,Neutralising,Bleaching,Deodorization and Dewaxing. 

1. Degumming
This is also the pretreatment of oil refinery. Degumming is to remove the phosphatides and mucilaginous material in crude oil. Phosphatides had strong hygroscopy and its existence is not good for edible oil storage, but it has high nutrition and wide application. The removal of phosphatides is the essential part of oil refining. This step adopts hot water or alkali electrolyte solution. The phosphatides puff by absorbing water, then precipitate and separate out from the oil. 
2. Neutralization
The second step is neutralization. It is to remove the Free Fatty Acids(FFA) by adding caustic soda. Thermic fluid oil is needed here to heat crude oil to about *0°C. Then stir the crude oil, and the chemical reaction can create soap stock, which settles at the bottom of the tank and taken out.
3. Bleaching
Neutralized oil now enters into the next vessel where the unpleasant colour is needed to remove. During this step we use bleaching earth which has strong adsorbability in high temperature. The thermic fluid oil temperature should be upto **0°C which ensures good adsorbability, and stiring is necessary too. The adsorbed residue and bleaching earth are filtered through filter process.
4. Deodorization
The clean bleached oil is then drawn to deodorizer to the last step-deodorization, to remove the volatile odoriferous material and free fatty acids. This step operates under high vacuum. The oil is heated upto **0°C and then live steam is piped, the oil temperature continuously rises to ******0 °C. The smell is removed and the deodored oil fluids to cooler to cool by circulating oil. Again, it should undergo the second time filtering and then refined edible oil is obtained.
