Shandong Leader Machinery Co.,ltd. the crude oil is output by the oil feed pump from the oil tank, and cottonseed oil manufacturing process next enters the crude oil heat exchanger to recover part of heat cottonseed oil manufacturing process after metering and then is heated to the required temperature by the heater. After that,cottonseed oil manufacturing process is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and New design processing equipment for soyabean oil then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and New design processing equipment for soyabean oil the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process. cottonseed oil manufacturing process there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture

1.Automatic production process of soybean oil making plant
Pretreatment: The pretreament is the necessary to make the oil,generally speaking the pretreatment including cleanning,decladding,softening,flaker and so on.
Cleaning: it will remove the impurity from the material to improve the quality of the oil.
Softening: Increasing the material elastoplasticity by controlling the wet and the temperature,so that improve the oil yield.
Flaker:The material should have the balance of the thickness,have the suit size,not lost of the oil and so on.
Press: Oil press operation, will handle good embryo into the hopper, oil from the hopper into the pressing chamber.By squeezer to advance into the spiral, squeezing.Because of material embryo in oil press in the bore of the press is under the running condition, under the condition of pressing chamber pressure, embryo and produce a lot of friction between squeezer, pressing chamber resistance.So you can make the embryo and material embryo produces friction caused by relative motion.Another face, squeezer root circle diameter is gradually enlargement, when press screw rotation, thread to make material embryo outward to move forward and reverse, at the same time close to squeeze material layer on the surface of the screw thread with pressing shaft rotation, which in the pressing chamber of each embryo material particles are not the same direction of the movement speed, etc.And also there is relative motion between particles.Friction heat and satisfy the oil necessary to process operations on a quantity of heat, helps to embryo protein denaturation, destroyed the colloid, increased the plastic, but also reduces the viscosity of oil, easy to squeeze out the oil, thus increasing the spiral oil press.
2.Extraction
Using normal hexane to getting more oil, to improve the oil yield.
3.Refining
Degumming:We are using a special wet degumming,Thorough removal of colloid. Improve the quality of rice bran oil.
Decoloring :Premixing the a certain amount of clay with 20% degumming oil in the premix tank , then using the oil pump pump the premixing oil and the rest 80% oil in the vacuum decolorization tower to get rid of the pigment,then using platetype filter to separate the oil and the waste clay.
Dewaxing:Wax affects the taste of the oil and it's transparency.Poor solubility in oil, cannot be absorbed by human.
Deacidification /Deodorization:Avoid large amounts of neutral oil accident losses, using high temperature and high vacuum environment, by using the method of steam stripping deodorization, removing acid.
Degrease:Different from other oil,rice bran not only exists wax,but also exists fat at low temperature.Effective separation of solid fat are more critical in the process
4 . Advantages
(1) High oil yield , obvious economic benefit .
(2) Lower residual oil rate in the dry meal .
(3) Improving the quality of the meal .
(4) Low processing cost , high labor productivity.
Our company
Workshop of Plant
Shandong Leader Machinery Co.,ltd. there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, cottonseed oil manufacturing process add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. New design processing equipment for soyabean oil To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and New design processing equipment for soyabean oil then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, cottonseed oil manufacturing process and the waste water is discharged to the sewage treatment station.and then Shandong Leader Machinery Co.,ltd. the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.
