Semi-automatic oil press is also a kind of oil press equipment. It is also a kind of mechanical equipment used to process oil crops into edible oil. It is mainly used in sesame, rapeseed, peanut kernel, cottonseed, soybean, tea.
    Oil production of oilseed crops such as seeds and corn germs.
    The operation of this oil press equipment is simple and convenient. Compared with other oil extraction equipment in terms of oil production rate, it provides farmers with a great help in squeezing edible oil. It is welcomed by farmers ’friends and is semi-automatic.
    Oil machine generally refers to hydraulic oil press or screw oil pressFeed the processed oil from the hopper of the semi-automatic oil press into the press chamber. By pressing the screw, the material embryo is continuously pushed inward for pressing. Because the material embryo is carried out in a moving state in the press chamber of the oil press, under the condition of high pressure in the press chamber, a large frictional resistance is generated between the material embryo and the screw snail, the material embryo and the press chamber. It can cause friction between the raw materials and micro-materials, causing relative movement.
   On the other hand, since the diameter of the root circle of the snail is gradually increasing, and the pitch is gradually decreasing, when the snail is rotated, the thread can advance forward and turn outward, and it is close to the snail's thread. The material layer on the surface also rotates with the press shaft. In this way, each of the particles in the embryo of the oil press does not move at the same speed and move in the same direction, but there is also relative movement between the particles. The heat generated by the friction also meets the necessary heat for the operation of the oil pressing process, which helps to promote the thermal denaturation of the protein in the embryo, destroys the colloid, increases the plasticity, and also reduces the viscosity of the oil, and it is easy to precipitate the oil. The oil output rate of the semi-automatic oil press is improved, so that the oil in the oil is squeezed out and flows out from the gaps between the row and the row.
