These oil press machine after more than ten year’s investment and modification, are concise in structure, easy to operate, and similar in performace to the advanced oil nuts, beans, sesame seeds, cotton seeds, and many other oilseeds crops.This oil expeller machine is composed of feeder, gearbos, pressing cage, screw shaft and machine stand etc.This kind of screw oil presses utilizes the screw shaft which is set-up with different styles of screws and rotates when machine is running to push the material into chamber. Then the oil is separated out through the extrusion of pressing worm and pressing ring. This oil extraction machine is in accordance with the standard JB/T9793.1-1999 for screw oil press for farm use,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 coconut oil press 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.
5.The quality of oil is pure.
6.Occupied workshop area is small.
7.Mechanical and electrical are integral.
8.High hardness and strength, good abrasion resistance and long using life.
