Soybean Oil Refining Machine covers entire processing line from crude soybean oil washing and degumming, alkali refining, mixed proportion, decolorization, leaching, physical deacidification and deodorization, crystallization and maturing system, blenching clay quantitative system, freezing filtration and fatty acid recovery system. During all processing of soybean oil refining machine, electrical control system is used in order to make sure the highest quality soybean oil production. The soybean oil after oil refinery process allows edible soybean oil with high purity, high oil yield, low residual oil and low environmental pollutions.

Process of 10T/D Soybean Oil Refining Machine
1. Degumming
Degumming process use hot water to hydrate phosphatides and get them removed. The oil then go through heating, drying and cooling. Before degumming, a plate oil filter is utilized to reduce the content of mechanical impurities, and further avoid emulsification or too much neutral oil contained in foots. The hydrated oil foots can be dried for lecithin, which is used for food additives and feed additives.
2. Neutralizing
The purpose of neutralizing is to remove free fatty acids (FFAs). Accompanied with continuous stiring, caustic solution (NaOH) are pumped into the degummed oil to react with free fatty acids and form soapstocks, which settle down and are pumped into the soapstocks tank for recycling. The oil is pumped into water tank and washed by hot water for 2-3 times till the waste water is clean, then dried and cooled. The byproduct soapstock can be used for manufacture of soaps and biodiesel, added in livestock feed, or treated for the fatty acids it contains.
3. Bleaching
Bleaching process use bleaching earth to remove pigments in oil. Degummed and neutralized oil are pumped into this system, preheated and then mixed in the bleaching tank under vacuum state with…...

Oil Processing Process, Edible Oil Mill Machinery Manufacture

...Processing of oil from plants or seeds needs high expertise and knowledge along with advanced technology. To process the oil from the source, a detailed and systematic is carried out. The process includes a number of procedures from seed cleaning, dehulling, cracking, heating, expelling, filtering to refining. Cleaning of the seeds can be done with seed cleaners. These machines are designed to remove any kind of metal, stone, rot seeds and other impurities or extraneous materials before dehulling. The stripped seeds then pressed to ensure more surface area. For crushing the seeds, mechanized grooved rollers and hammer mills crush can be used for ensuring proper material consistency. After this, the seeds are heated for the extraction of the oil. The heated seeds are fed constantly into a screw press that enhances the pressure gradually as they pass through a slotted barrel. When the initial oil is recovered from the screw press, the remaining oil cake in the press is also processed using solvent extraction. Volatile hydrocarbon is commonly used to dissolve the oil out of oil cake that is recovered by distillation method. Different machines are used for solvent percolation through the matter that is occasionally dumped and replaced. We can produce all kinds of edible oil mill machinery, which includes peanut oil production line, soybean oil, cottonseed oil, sunflower oil, corn oil, rice bran oil and other kinds of edible oil production line.

If you are interested in it and you plant to start a soybean oil mill plant, please read on. 1• Cut 1.75-inch metal tubing into two 24.5-inch pieces and one 6.5-inch piece. A carbide saw blade is essential to cut metal; these are available for whatever type of powered or unpowered saw you use to cut the tubing. • 2 Cut a 5.5-inch piece of flat steel bar and two 8-inch pieces of angle iron. The bar will serve as the top crossbar in your frame while the angle irons will join the frame to a wooden base. 3• Stand all three tubes on their ends, with the long tubes 5.5 inches apart. Place the short tube in between them and use an arc welder to weld the steel crossbar at their top ends, and the angle iron pieces on both sides of their bottom ends. This will make a rectangular metal frame with the short pipe in the middle of one short side. • 4 File or grind any rough edges from your frame, then paint it. The paint will dampen down any shavings. Once painted, it can be attached to a wooden base by passing screws through the holes in the angle iron piece. • 5 Make the press canister by welding a circular piece cut from your plate steel onto one end of a wide steel tube. Drill holes through the outside of the canister and file down any rough edges. • 6 Form the press piston by cutting......

Why Squeeze Peanut Oil Needs Refining

...the existence of some oil of mildew, machine pressed crude oil of mildew toxin can be greatly exceeded, such as peanut oil is very easy to be contaminated with aflatoxin, and the content of aflatoxin sometimes as high as 1000-10000ug/kg. So the SQUEEZE PEANUT OIL takes the oil to be refined to consume. Yellow aspergillus toxin belongs to the drama of poison, its toxicity is higher than potassium cyanide, is the most chemical carcinogens in currently found, carcinogenicity was 900 times of yellow butter, and 75 times than dimethyl nitrosamine induced hepatoma capacity. Aflatoxin can accumulate to a very high level in adipose tissue, and it is highly toxic. Aflatoxin can inhibit the coupling of respiration and oxidative phosphorylation in the squeeze peanut oil, which is toxic to the mitochondria, which is the common cause of the common causes of poisoning and biochemical damage. After being contaminated by aflatoxin, poultry consumption is associated with acute, subacute or chronic toxic effects in the edible part of its edible part and in the milk. Human consumption of aflatoxin contamination of food, the incidence of liver cancer, many of which can be associated with hepatitis B virus to induce liver cancer. So the squeeze peanut oil needs refining. The heat resistance of aflatoxin is not easy to break down at the temperature of the common cooking process, which is more than 280 degrees Celsius. Thus, the squeezed peanut oil can be removed by refining the toxin. In our......
