Screw oil press is a kind of machine that can squeeze oil out of oil by increasing temperature and activating oil molecules.
Working principle of screw press:
When the screw press is running, the processed oil enters the press chamber from the hopper. From the press screw to make the material embryo continuously push in, press. Because the material embryo is in motion in the press chamber of the screw press, under the condition of high pressure in the press chamber, there is a great friction resistance between the material embryo and the press screw, the material embryo and the press chamber, so that the friction between the micro materials of the material embryo can be produced, resulting in relative movement. On the other hand, because the diameter of the root circle of the screw is gradually increased and the pitch of the screw is gradually reduced, when the screw is rotated, the screw can push forward and turn outward, and the material layer close to the screw surface also rotates with the screw shaft. In this way, the particles of each material embryo in the squeezing chamber are not moving at the same speed and in the same direction, but there is also relative movement between the particles. The heat generated by friction meets the heat required by the operation of the oil pressing process, which helps to promote the thermal denaturation of the protein in the material embryo, destroy the colloid, increase the plasticity, and reduce the viscosity of some oil, so as to improve the oil yield of the screw oil press, so that the oil pressure in the material can be squeezed out, and flow out from the circular row gap and the strip row gap.
Advantages of screw press:
The screw press has the advantages of small floor area, high production efficiency, exquisite material selection, reasonable structure, beautiful appearance, reliable quality, simple operation, labor saving and power saving, and has the special advantages of automatic temperature control, one-time pressing, high oil yield, vacuum filtration and high production efficiency. More than 20 kinds of oil products, such as sesame, peanut, rapeseed, tea seed, soybean, oil sunflower, flax, cottonseed, corn, walnut, can be processed with one machine and multiple uses. After vacuum filtration, the four-stage pressed oil is fragrant, attractive, crystal clear, safe and sanitary, and can be directly consumed or bottled for sale.
1. High oil production rate. Compared with the old equipment, the normal oil output rate can be 3-6 percentage points higher, and the economic benefit is very considerable.
2. Energy saving and environmental protection. The power consumption is reduced by 40% for the same output, and the daily production cost can be saved by 36 yuan based on the average saving of 6 kwh per hour.
3. The oil is pure. Vacuum filter residue to ensure the purity of oil, the original flavor of the extracted oil, no pollution, in line with the requirements of health and epidemic prevention.
4. Small floor area. The oil workshop only needs 10-20 square meters.
