New design corn germ oil refining machinery price
ABOUT REFINING PROCESS:
FEATURES:
1. Easy to operate and continuously; 2. Low laboring tense;
3. Keep good environment condition; 4.Keep oil residence in deposable bleaching earth in low level.
MAIN STEPS OF EDIBLE OIL REFINING:
1. Crude Oil Degumming: Gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization: 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: It 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 oil, maize germ or corn oil contains 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.
