1.  Screw oil press working principle:

?   When oil press is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.

?   Under high temperature condition in the chamber, there is quite strong friction among press screw, chamber and the oil materials.

?   On the other hand, root diameter of the pressing screw carries larger from one end to the other.

?  .Hence when rotating, the thread not only pushes particles moving forwards but also turns them outwards as well.

?   Meanwhile, particles adjacent the screw will rotate along with screw’s rotating, causing every particle inside the chamber to possess different speed.

?  Therefore, relative movement among particles creates neat which is necessary during manufacturing because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil.
