DFM-70 Oil Press/Oil Expeller

Oil press/ oil expeller Features:

1.small land-using: only need 10-20 square meters

2.save labor: it is automatic ,only one can make the production

Application:  Automatic oil expeller consists of expeller and auto vacuum filter. It can finish the whole process from raw materials (after sorting and shelling) to completed oil.  it is suitable for more than 20kinds crops,such as, peanut, sesame, grapeseed, blackseed, sunflower seed and so on.

Operating principle of oil expeller/oil press

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

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

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

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

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

6. 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.
