Simple structure, easy to use, adaptable, high oil rate, energysaving, and low noise.Material selection is exquisite, reasonable design, beautiful shape, reliable quality.
Simple operation, less land occupation, labor saving, power saving, high yield, and oil quality is good, and so on.
All technical indexes are leading in the same trade of the stateowned oil press. And the model of 6YL-80 and 6YL-100 are the new type products reformed by our factory engineers,
which are the advanced equipment in the oilseeds processing machinery recently.
Operating principle
1.When small oil expeller is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and be 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.
Construction features of  castor oil screw press:
6YL series spiral oil press is mainly composed of 7 major parts of screw axis, press cage, feed mechanism, cake yielding mechanism. transmission system,
electric control part and vacuum filter part. All the parts are assembled on the frame and screwed as a whole.
