Edible oil refining Hot sale soyabean oil extraction machine with good supplier 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.

1. Soyabean oil extraction machine,equipment Process:
Material embryos extraction Wet meal Evaporation Cooling Product meal packing
Mied oil Filter Negative pressure evaporation Crude oil
Solvent recovery
2.Soyabean oil extraction machine,equipmentFunction:
Leaching system is an oil extraction through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.
3. Soyabean oil extraction machine,equipment Main parts:
1. Solvent pumps: continuously spray solvent to the rotary-type etractor
2. Roary etractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be diss-olved in solvent(form miscella). After processing, you can get wet meal and miscella (mied oil).
3. DTDC: usd to separate the solvent from the wet meal.
4. Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , then add saline water to it. The phospholipid in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.
5. Miscella tank 2nd: the purified miscella will be pumped into it.
6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

5. Soyabean oil extraction machine,equipment Advantages:
1. High oil yield , obvious economic benefit .
2. 1% Residual oil rate in the dry meal .
3. Improving the quality of the meal .
4. Low processing cost , high labor productivity.
6. Certification:
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 Hot sale soyabean oil extraction machine with good supplier 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 Hot sale soyabean oil extraction machine with good supplier process can be combined with deodorization step described under FFA stripping.Physical Refining process Hot sale soyabean oil extraction machine with good supplier 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.
