Screw small coconut oil press machine is a screw-driven cold press oil expeller machine that used to
extract oil from seeds and kernels for edible or biofuel purposes. Our screw oil press machine can
process a great many plant seed such as peanut, soybean, sunflower seeds, sesame seed, cottonseed,
rapeseeds, corn germ, coconut, palm kernel, jatropha seed, hemp seed, castor seed etc.During
the press running, the processed oil plants from the hopper into the press chamber. The oil expeller machine press the raw material by push foward them. Under the condition of the high pressure in the
press chamber, the raw material and press screw and press chamber had a huge frictional resistance,
so that cause friction between micro raw material, due to relative motion. On the other hand,
because of the diameter of screw is gradually enlarged, but the screw thread is gradually reduced, thus
when oil extraction machine screw rolling,the screw thread forced the material move foward and can flip outward,
at the same time, the surface layer of material closed to the press screw thread is rolling with the press shaft,
so that caused the micro raw materials are not moved constant speed and same direction, but exist a relative
motion between micro raw materials. And the heat caused by friction meet the necessary heat of oil process operations,
helps to feed protein denaturation in the raw material,destroyed colloid, increased the figurability, and reduce the viscosity
at the same time, easy to precipitate oil, thus increasing oil producing ratio of the oil press.
advantages of screw oil press machine
1. With automatic temperature rising and oil-cleaning system, these series screw oil press machines are able to do both
cold pressing and hot pressing.
2. These series screw oil press machines are not only integrate with heating, expelling and filtering, but are also capable of
controlling the processing temperature automatically.
3. The screw oil press machines are characterized by high rate of oil output and great oil quality.
4. These screw oil press machines use electronic pipes to heat the press case, which helps the press case meet the
requested temperature in a short time to increase the rate of oil output.
5. These screw oil press machines are used for various raw materials, such as: ground nuts, bean, rice bran,
rape and cotton seeds, sesame, olive, sunflower, coconuts and cocoa and grass seeds.
6. They are widely used in medium-small sized oil extruding workshops or professional farmers.
