Excellent technology soy oil extraction soybean press
1. soy oil extraction soybean press :
When oil press operating, the prepared materials enter the pressing chamber from the hopper and then move forwards by the rotating of pressing screw and is pressed under the high-pressure condition in the chamber, friction between material and chamber will be created, which also created friction and relative movement among material particles, on the other hand, root diameter of the pressing screw carries larger from one end to the other. hence, when rotating, it not only pushed particles moving forwards but also turns them outwards as well, meanwhile, particles adjacent the screw will rotation along with screw’ rotating, causing every particle inside the chamber to possess different speed, therefore relative movement among particle creates heat which is necessary during manufacturing. because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil productivity.
soy oil extraction soybean press production :
2. soy oil extraction soybean press-----solvent oil extraction:
It is adapt solvent to steep or leaching the oil materials,to extract out the oil from oil materials and dissolved in solvent,and then get the miscella which contain solvent and oil both after filtration.To heat miscella,and the solvent will be evaporated and solvent-oil sepration,and then get crude oil.The crude oil after refining(hydration,alkali refining,decoloring and more),to become the edible oil which according to national standard.The evaporated solvent could be used circularly after cooling.
Soybean oil solvent extraction advantages:
1.High oil yield,and the residual oil is less than 1%.
2.High quality cake.Solvent has a stong ablity to extract oil,so that it can get oil without heating completely to use solvent extraction method,and protect rich of soluble protein in water,and the cake could be used to make vegetable protein.
3.Lower labour strength.
