Screw oil press is advanced oil processing machinery

Screw oil press is advanced oil processing machinery, characterized by their simple design, easy to use, wide suitability and continuous operation; and high productivity and high oil output rate. Moreover,the oil press machine can be used for various raw materials, as ground nuts, bean, rape seeds and cotton seeds, sesame, olive, sunflower, prickly ash seeds, bancoul nuts, grass seeds. They are suitable for medium-small sized oil extruding workshops or professional farmers. Certainly, the screw oil press machine can be used for repressing in submerging oil workshops, too.

1.Oil press has multiple functions, including vacuum filtration system, automatic heating device .Before pressing, some parts of the oil press such as the press chamber, press screw will be pre-heated.
2.The oil press is matched with one controlling cabinet box for controlling all working of the machine.
3. Labor saving and electricity saving, high oil yield and nice performance.
4.Wide application Such oil press can apply to more than 20 kinds of oil crops such as the coconuts,sunflower, soybean,cotton seeds , tee seeds, rice bran, flaxseeds, sesame, peanuts, rape, cocoa and grass seeds, corn pummels etc.the screw oil press machine is used with peanut roaster machine
5. Some parts of the oil press will be pre-heated before pressing, such as the press chamber, press screw and press ring.
6. During pressing, the press will filter the oil in due time.

Operating principle of screw oil press machine

1.When screw 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.

2.Under hightemperature 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.
