Edible Oil Cake Solvent Extraction Plant- Rotary Extractor
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.
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.
In Physical Refining, Vegetable Oil is subject to distillation to remove free fatty acids. The alkali treatment is completely avoided. This reduces the amount of waste water and eliminates production of soap. This process is becoming more popular.
In Chemical Refining, Vegetable Oil is treated with caustic lye for separation of free fatty acids from oil. This is a conventional process that can be applied to all oils. A byproduct of alkali refining is soap-stock, which is used for manufacture of low quality washing soap. Alternately, the soap-stock can be treated with acid to recover fatty acids. The waste-water from refinery requires extensive treatment. This can be avoided by alternate Physical Refining process.Physical Refining
In Physical Refining, Vegetable Oil is subject to distillation to remove free fatty acids. The alkali treatment is completely avoided. This reduces the amount of waste water and eliminates production of soap. This process is becoming more popular.Degumming
The purpose of Degumming Vegetable Oils is to remove Gums. All oils have hydratable and non-hydratable gums.
a. Water Degumming: Hydratable gums are removed by treating oils with water and separating the gums. The gums can be dried to produce lecithin.
b. Acid Degumming: Non-Hydratable gums are removed by treating oils with acids and separating the gums.Neutralizing
The purpose of Neutralizing Vegetable Oils is to remove Free-Fatty Acids (FFAs). Traditionally, FFAs are treated with caustic soda (NaOH). The reaction produces Soaps which are separated from the oil. Because trace amounts of soaps remain in the oil, the oil is either washed with water or treated with Silica.Some processors prefer not to perform caustic neutralizing. Instead, they prefer Physical Refining in which the FFAs are evaporated from the oil under high temperature and vacuum. This process can be combined with deodorization step described under FFA stripping.Physical Refining process is preferred because (a) it does not produce soaps; (b) it recovers fatty acids that provide better cost recovery; (c) there is smaller yield loss compared to caustic refining—especially for oils with higher FFAs; and (d) it is a chemical-free process.Bleaching
The purpose of Bleaching is to remove color pigments contained in Vegetable Oils. The oil is treated with Bleaching Clays that adsorb the color pigments. The clay is filtered and the clean bleached oil is stored for further processing. Process flow diagram is attached.Deodorizing
The purpose of Deodorizing Vegetable Oils is to remove odor substances. The oil is subjected to steam distillation under high temperature and vacuum to evaporate all odor substances. The resulting deodorized oil is almost bland and tasteless.
