Screw type oil press machine are 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, they can be used for various raw materials, as ground nuts, bean, rice bran, rape and cotton seeds, sesame, olive, sunflower, coconuts and cocoa and grass seeds. However, they are suitable for medium-small sized oil extruding workshops or professional farmers. Certainly, the oil expeller machine can be used for repressing in submerging oil workshops, too.When peanut oil press machine is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.Under hightemperature 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.

features of screw oil press machine

1.High oil yield: low oil residual in cake. The oil left in cake is less than 6% ; Cake thickness can be adjusted while machine stops running;
2.Pure oil quality: machine surface is made of chrome plated stainless steel, in line with food hygiene standards; Besides, with two vacuum oil filters, residual can be removed by simple filtering;
3.Environment friendly: integrating advantages of traditional oil press machine, the new design machine are noiseless, no pollution, which can better meet environmental standard.
4.Energy saving: our automatic peanut screw oil press machine can reduce 40% of energy under the same output. for example, the oil extraction machine can save 6 kilowatt at an average of one hour.
