Edible Oil Refinery Plant Manufacturers

As we all know, edible oil refinery is quite important part in the entire edible oil processing plant, there are indeed a lot of edible oil refinery plant manufacturers all over the world, but you should  select the oil mill machinery manufacturer with good reputation and rich practical experience.

 

There are three basic oil refining plant processes in the refinery.

1. Neutralizing the oil in the neutralizer to remove the Free Fatty Acids (FFA) by adding caustic soda. Oil is heated upto about 60C 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.

2. 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 C by thermic fluid coils. Stirring is also continued. Bleaching process is done under vacuum.

3. 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 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 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.
