Oil Expeller Operation Principle
When Small oil expeller is operating,prepared materials enter the extruding chamber from the hopper and then moves forwards by the rotating pressing screwed and is pressed.Under the high pressure condition in the chamber,friction between material and screw,It will be created,which also creates friction and relative movement among material particles.On the other hand,root diameter of the pressing screw varies larger from one end to the other ,hence,when rotating,it not only pushes paritcles moving but turns them outwards as well.Meanwhile particles adjacent the screw will rotate along with screw's rotating,causing every particle insides the chamber to possess different speed.Therefore,relative movement among particles creates heat which is necessary during manufacturing because of helping protein change properly,damage colloid,increase plasticity,decrease oil elasticity ,resulting in high oil productivity.
