Edible oil refining Good quality soya bean oil extraction machine for sale 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 Small Coconut Oil Mill Machinery, Shandong Leader Machinery Co.,ltd. 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: Small Coconut Oil Mill Machinery Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.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.Bleaching: During bleaching, 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 (necessary for cold areas)Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these Shandong Leader Machinery Co.,ltd. 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.
Good quality soya bean oil extraction machine for sale
The feature of soya bean oil extraction machine:
1. Adopt stainless steel fied grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good etraction effect;
2. The rotocel etractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;
3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the etractor and reduce the solvent leakage.
4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity.
5. The high material layer of the etractor helps to form immersion etraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling. 6. Specially suitable for the etraction of various pre-pressed meals.
The paratemer of soya bean oil extraction machine:
The process of soya bean oil extraction machine:
(1) The plant seedoil (for pretreatment) is sent to rotary etraction by the scraper conveyor. The plant seed oil will etracted by the solvent or mi oil. After this step, we will get meal and mi oil.
(2) Meal is send to toaster. Through the toaster, the solvent in the meal will seperate from the meal. The solvent goes to condenser and is recycled to rotary etraction.
(3) After the mi plant oil from the rotary etraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the plant seed oil is separated.
(4) The mi plant oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude plant seed oil and solvent. The solvent is sent to condenser and is recycled to rotary etraction.

Our honor should be more convincing:
The purpose of Neutralizing Vegetable Oils Small Coconut Oil Mill Machinery 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 Good quality soya bean oil extraction machine for sale trace amounts of soaps remain in the oil, the oil is either washed with water or treated with Silica.Shandong Leader Machinery Co.,ltd. 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 Good quality soya bean oil extraction machine for sale process can be combined with deodorization step described under FFA stripping.Physical Refining process Good quality soya bean oil extraction machine for sale 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.
