sunflower oil refinery mill/Batch Oil Refinery/Crude vegetable oil refinery plant

--Brief introduction of oil refinery

Edible oil refining includes a series processing procedures as degumming, neutralization, bleaching, deodorization and winterisation. In general there are two methods of vegetable/edible oil processing, one is physical refining and the other is chemical refining. However, no matter what kinds of reining methods, they are all done with the help of various oil processing equipment and machinery, and are used to refine almost all kinds of oil extracted from oil seeds like sunflower seeds, peanuts , sesame seeds, and soya bean seeds etc.

---Chemical refining&physical refining

Edible/vegetable oil refining is a step by step process. Refining oil removes phospholipids, pigments, off-flavors, free fatty acids and other impurities. The entire oil refining plant process comprises degumming/neutralization, bleaching, deoderization, and winterization. Chemical refining is performed in order to remove the fatty acids from the crude oil that is extracted from the seeds. These are further neutralized with the use of caustic soda. This results in the removal of sodium soaps by batch settling or centrifugal separators. The neutral oils are then bleached and deodorized.

 Apart from chemical refining, another method that is used for edible oil refining is physical refining. Through this method, the free fatty acids are removed through the process of distillation in one stage of deodorizing. In order to come up with effective results, the crude oil should be thoroughly degummed. This is not applicable with some oil like the oil extracted from cottonseeds. All kinds of refining methods are done with the help of various equipment and machinery, and are used to refine almost all kinds of oil extracted from oil seeds like sunflower seeds, linseeds, groundnuts, sesame seeds, and mustard seeds, etc.

 Physical and chemical refining is defined according to the technology used. Physical refining means the removal of gum in oil via the process of degumming, a special method for removing FFA in the process of deodorization by steam. Chemical refining, however, means chemically removing FFA (acid-base neutralization). Gum and soap produced is then separated by centrifuges.

Main Steps of Edible Oil Refining

1. Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.

2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.

3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.

4. Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.

5. Dewaxing (necessary for cold areas)

Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.

Some Edible Oil Refining Equipment Instruction

1. Decoloring tank: bleach pigments from oil.

2. Deodorizing tank: remove the un-favored smell from decolorized oil.

3Oil furnace: provide enough heat for the refining sections which need high temperature of 280℃.                                

4. Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755mmHg or more.

5. Air compressor: dry the bleached clay after bleaching.

6. Filter press: filter the clay into the bleached oil.

7. Steam generator: generate steam distillation.
