Cooking Oil Refinery Process

KMEC's complete set high quality cooking oil refinery plant applies to variou kinds Refining Unit. Cooking oil refinery process including de-gumming, de-acidification, bleaching and deodorization. The finished oil reaches national standard of high quality cook oil. This unit requires small investment and obtains instant effect. It is more suitable for small scale oil mills and private entrepreneur.This unit has 10 models with capacity from 300kgs to 5000kgs per day.

For refining the oil, there are three basic processes in the refinery. First process is neutralizing the oil in the neutralizer to remove the Free Fatty Acids (FFA) 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.

Cooking Oil Refining Process

Neutralized oil is drawn into the second vessel called bleacher where colour of oil is removed by bleaching process with aid of chemicals such as carbon black and bleaching earth. Oil is generally heated upto 110°C by thermic fluid coils. Stirring is also continued. Bleaching process is done under vacuum.

Bleached oil then 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 upto 200 to 220°C through thermic fluid coils. Entire 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.

Micro filtration is done after the cooling process of oil in cooler. This process is done in a micro filter press which makes the final output oil that is refined cooking oil. The filter press is specially designed for better filtration and better quality of final refined cooking oil.
