The working principle of the screw oil press:
When the screw press is running, the processed oil enters the press chamber from the hopper. The material embryo is continuously pushed inward by the pressing screw for pressing. Because the material embryo is in motion in the pressing chamber of the oil press, under the condition of high pressure in the pressing chamber, a great frictional resistance is generated between the material embryo and the screw press, the material embryo and the pressing chamber, so that the It can cause friction between the micro-materials of the blank and cause relative movement. On the other hand, since the diameter of the root circle of the screw press is gradually thickened and the pitch is gradually reduced, when the screw press rotates, the thread can push forward and turn outward, and at the same time close to the screw thread. The material layer on the surface also rotates with the press shaft. In this way, each material embryo particle in the press chamber does not move at the same speed and in the same direction, but there is also a relative motion between the particles. The heat generated by friction satisfies the heat necessary for the operation of the oil extraction process, which helps to promote the thermal denaturation of the protein in the embryo, destroys the colloid, increases the plasticity, and at the same time reduces the viscosity. The oil output rate of the oil press is improved, so that the oil in the material is squeezed out and flows out from the gap of the garden row and the gap of the strip row.
Features of screw oil press:
Disadvantages of traditional oil extraction methods: primitive workshops, simple equipment, cumbersome operation, large floor space, high energy consumption, low oil yield, and poor sanitary environment.
Energy saving, advanced design, beautiful appearance, reliable performance, simple operation and convenient maintenance.
High oil yield—compared with the old equipment, the normal oil yield can be 4-6 percentage points higher, and the average oil yield is 4-6 catties per 100 catties of peanuts processed, and the annual economic benefits are very considerable.
Energy saving - the same output reduces the electric power by 40%, calculated on the basis of saving 6 kWh of electricity per hour on average, the daily production can save 30 yuan in electricity bills
Labor saving - the same output can save labor by 60%, 1 to 2 people can organize production, and the daily labor cost can be saved by about 40 yuan.
Wide range of uses - multi-purpose machine, can squeeze more than 20 kinds of oil crops such as peanuts, sesame, rapeseed, cottonseed, soybean, etc. Multi-stage pressing, one pressing.
Pure oil quality - vacuum filtration residual inspection, to ensure pure oil quality, in line with health and quarantine standards.
Small footprint - the oil mill only needs 10-20 square meters to be used.
