After oil is extracted from vegetable seeds, the crude oil should go through a number of different processes in cooking oil refinery plant to make it ready for human consumption. Simply defined, refining is the process of removing impurities which may be present in the crude oil. Such impurities include phosphatides, free fatty acids (FFA), waxes and gums. Besides, edible oil refinery machine also helps remove bad smell and dark color.
Small scale cooking oil refinery plant production capacity: 0.5ton/day~ 20ton/day
Oil refining process: deodorization, decoloration, degumming, neutralizing
Machine use for: refining all kinds of animal oil such as fish oil, beef tallow, and vegetable oil refining as sunflower oil, cotton seed oil, rice bran oil, sesame oil, coconut oil, peanut oil and palm oil
Degumming: the oils are subjected to acidic treatment. Gums are precipitated out and separated by the centrifugal separation process. When gum content is low, gum conditioning is applied instead.
Deacidification ( 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.
Decolorization : During decolorization, unwanted pigments are adsorbed physically and oil will become much clearer.
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.
Dewaxing: Oils such as corn oil and sunflower oil have waxes in them. When oil with waxes is kept in relatively low temperatures. The removal of waxes is the final step that a cooking oil refining plant takes before bottling and marketing its oil.
If you are interested in building a small cooking oil refining factory for starting an edible oil business locally and make big money, a small and cost effective cooking oil refinery plant is what need!
