1.When oil press operation prepare material enters chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed. 
2.Under the high pressure condition in the chamber ,friction between materials 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,when rotating,it not only pushes particles moving forwards but turns them outwards as well,meanwhile,particle adjacent the screw will rotation along with screw's rotating.
3.The oil flows through the ring teeth falls into a foodstuff-safe steel funnel. The press cake is transported out of the press via a freely adjustable press gap. This adjustable press gap makes it possible to process many different types of seed. Whereby the press cake, that is in chip form falls out of the bottom of the machine.
4.The presses are driven by a electric motor. it is also can be driven by diesel engine for customers to reach continue working performance, where the power is not so stable.
