Edible oil refining Sunflower extract machinery,sunflower oil machine south africa 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.

I Technological process introduction:
II Solvent extraction process:
A Towline Extractor Advantages:
1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.
2) Immersion area appears in each lattice, which can help achieve better immersion effect.
3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.
4) The towline extractor is driven by world leading double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.
5) Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.

B Wet Meal Desolventizing Process:
Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and improve meal value in use.
Control the protein denaturation degree in the meal , and improve the NSI index effectively.
It can better regulate the color, flavor and taste of the meal.
It can better reduce residual solvent in the meal and regulate the meal moisture, so as to guarantee the minimum solvent consumption and safe use of the meal.

C Negative pressure evaporation process:
The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.
Vacuum evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.
Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment.
Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.
D Solvent condensation & recovery process:
Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, non-condensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated from water goes to solvent holding tank. The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy.
Non-condensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser. The solvent gas from the extractor enters extraction condenser, and the non-condensable tail gas enters the final condenser. For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low-temperatured cold water to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.
E Paraffin oil recovery process:
Tail gas first enters paraffin absorption tower, and then comes the counter-current absorption of paraffin and tail gas, which can reach the ideal state when the stainless steel packing has large surface area. The solvent content in discharged liquid paraffin (called rich oil) is not more than 5%, so as to ensure the maximum absorption rate.
he paraffin rich oil is pumped into the heat exchanger to exchange heat with paraffin lean oil, and then goes to paraffin heater, and finally enters paraffin analysis tower. In the analysis tower, the steam-liquid heat exchange is conducted on the surface of stainless steel packing surface with direct steam and rich-oil paraffin, which can remove the solvent in the paraffin. This kind of paraffin, also called lean oil, exchanges heat with rich oil, and then is cooled to the ideal absorption temperature through the cooler. Next, it enters absorption tower for recycling. The gas mixture from the analysis tower enters energy saver, and the tail gas from the absorption tower is discharged from workshop with the fan.
In solvent recovery system, the solvent enters the holding tank through water tank, and the condensed waste water is discharged from water tank. If the tail gas contains certain solvent, cook it with the cooker to make it meet the emission requirements.

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 Sunflower extract machinery,sunflower oil machine south africa 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 Sunflower extract machinery,sunflower oil machine south africa process can be combined with deodorization step described under FFA stripping.Physical Refining process Sunflower extract machinery,sunflower oil machine south africa 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.
