Edible Oil Refining

Edible oil from extraction need to refine before using. And for refining, there are three basic processes for edible oil refining.
 

Neutralizing
The edible oil in the neutralizer to remove the Free Fatty Acids by adding caustic soda. Oil is heated upto about 60°C by thermic fluid coils and oil is stirred by stirrer. Then soap stock formed due to chemical reaction is allowed to settle at the bottom of the neutralizer from where it is taken out into soap pan.

Bleached
Edible oil goes to the filter press where bleaching earth and chemicals are separated and clean bleached oil is then drawn to deodourizer where oil is heated above 110°C through thermic fluid coils and then live steam is given to the oil from the bottom steam nozzles and temperature of oil is raised up to 200 to 220°C through thermic fluid coils. The whole edible oil refining process is done under high vacuum. Thus smell is removed from the oil in the deodourizer. Then it goes to cooler where water circulating coils take away heat and oil is cooled. Again it goes to second filter press where completely refined and transparent colour less oil is obtained.
 

However, some other edible oil refining need additonal process. You can email us for more information according to your requirements.
