soybean oil extraction machine utilizes the screw that us set-up with different styles of screws and rotates when machines is running to push the materials into chamber. Owing to the spiral helical pitch of screws becomes shorter and the spiral depth of screw. Becomes shallower, in the chamber the volumes between screws and pressing ring inner is smaller, pressure produced from curve saw-tooth of pressing ring inner, which oil is separated out. Oil releases from the gaps between bars and oil slots between pressing rings. Cookie releases from the cookie releases state.When the raw materials have been sent to the hopper of oil press machine and then been moved forward by the rotating pressing screw for pressing. Under the high-pressure condition in the chamber, friction between material and screw, chamber will be created, which also creates friction and relative movement among material particles. On the other hand, root diameter of the oil expeller machine for home use caries larger from one end to the other, hence. When rotating, it not only pushes particles to move forward,but also turns them outwards as well. Meanwhile,particles adjacent the scew will rotate 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 becasue of helping protein change property,damage colloid,increase plasticity, decrease oil’s elasticity, resulting in high oil productivity.

Advantages of screw type oil press machine:
1.High oil output rate–it can make 20kg-25kg peanut oil from every 50kg peanut.
2.Save energy—it can save 40% electricity compared with the similar machine in the market.
3.Save both labor and money—it just need 1-2 people to operate the oil expeller machine.
4.Wide using range—this oil expeller can press various kinds of oil crops, such as peanut, sesame, soybean, flax, rapeseed, oil sunflower, cottonseed.
