Oil sunflower oil press is suitable for oil sunflower oil pressing work, which is the abbreviation of “sunflower for oil”. It is one of the four major oil crops in the world. Sunflower seeds extracted from the oil, low cholesterol can be extracted from the high-grade edible sunflower oil, because it contains about 66% of the “linoleic acid”, known as the 21st century “healthy nutrition oil. Oil sunflower, namely “oil sunflower” for short. It is one of the four oil crops in China. Sunflower can be divided into two types according to the different USES, that is, oil-oriented sunflower sunflower (sunflower) and edible sunflower (sunflower). Oil sunflower is divided into conventional varieties and hybrid varieties, general conventional varieties can keep the seeds, and hybrids can not.
Oil sunflower seeds can be used to extract oil, oil residue (also known as “oil sunflower cake”) can be used as protein feed. Sunflower tray and straw can also be used accordingly. So oil sunflower oil press is widely used. When the oil sunflower press is running, the processed oil sunflower enters the press chamber from the hopper. The material embryo is continuously pushed in by the extrusion screw and pressed. From the oil sunflower oil press in the oil press in the press chamber of the embryo is in the state of movement, under the pressure of the press chamber, the material embryo and the press screw, the material embryo and the press chamber between a great deal of friction resistance, so as to make the material embryo micro material friction between the material, resulting in relative movement. On the other hand, because the diameter of the root circle of the screw is gradually thickened, the pitch of the screw is gradually reduced, so when the screw rotates, the thread force material embryo can be pushed forward, and can be turned outward, at the same time close to the screw thread surface material layer also rotates with the press axis. In this way, each particle of the blank in the press chamber is not moving in the same direction with the same speed, but there is relative motion between the particles. Produced by friction heat and heat necessary to satisfy the oil process operation, helps to material in the embryo protein denaturation, destroyed the colloid, increased the plastic, but also reduces some oil viscosity easy exhalation, thus increasing the spiral oil press, to squeeze out the oil from material, and article from row gap and the discharge gap flow out.
Matters needing attention
1, the oil cup above the reducer shall not be short of oil. When adjusting the screw shaft of the oil sunflower oil press, the inner bearing of the screw shaft shall be added with butter once per shift in the adjustment screw hole. Dry grinding is strictly prohibited.
2, each emollient parts should prevent the invasion of dust and other impurities, every year to check the oil quality of oil sunflower oil reducer gearbox once, found that the deterioration, should be replaced by all oil.
3, when the amount of oil press press reduced, out of the cake or out of the oil is not normal, should be squeezed out of the screw shaft, check the screw, squeeze strip, out of the ring wear, wear parts to be replaced in a timely manner.
4, after the end of each shift, should remove the oil sunflower oil press residual cake, wipe the machine surface dust, oil scale.
5. After long-term storage at the end of the production season, maintenance shall be carried out once, and the screw, strip and ring shall be removed, washed and re-oiled, and placed in a dry place.
