Oil expeller/oil press/oil machine Operation principle and structure
When oil press operating prepared material enters chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed. Under the high-pressure condition in the chamber, friction between material and screw, between material and chamber will be created which also creates friction and relative movement among material particles. On the other hand toot diameter of the pressing screw caries larger from one end to the other, hence, rotating, it not only prshes particles moving forwards but turns them outwards as well, meanwhile, particle adjacent the screw will rotation along with screw`s 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`elasticity, resulting in high oil productivity.
