When choosing an oil press with high oil yield, you need to consider the pressing method, raw material characteristics, equipment technology and other factors. Below are the characteristics of different types of oil presses and recommended solutions for high oil yield, below I recommend the screw oil press:
Working principle of screw oil press: When the oil press is running, the treated oil material enters the press chamber from the hopper. By the press screw turn to make the material embryo constantly pushed inward, for pressing.
As the material embryo in the press chamber of the oil press is in the state of motion, under the condition of high pressure in the press chamber, a great frictional resistance is generated between the material embryo and the press screw, the material embryo and the press chamber, so as to make the material embryo micro-feeding friction between the material, resulting in relative motion.
On the other hand, because of the root of the screw diameter is gradually thickened, the pitch is gradually reduced, so when the screw rotation, the threads make the material embryo that can be pushed forward, but also can be turned outward, at the same time close to the threaded surface of the screw screw layer with the rotation of the press shaft.
In this way, in the press chamber of each material embryo particles are not equal speed, the same direction of movement, but also in the particles of the relative movement between the existence of.
The heat generated by the friction and meet the oil extraction process operation of the heat necessary to help promote the thermal denaturation of protein in the material embryo, destroying the colloid, increasing the plasticity, but also reduces the viscosity of the easy to precipitate oil, thus improving the oil yield of the oil press, so that there are materials in the oil pressed out and from the garden row of slits and rows of slits out of the rows.
Screw oil press adopts four-stage pressing process, that is, the oil material is pressed four times inside the oil press. It ensures the maximum oil yield of tea seeds. So the screw oil press has high efficiency and high oil yield.
