Operating Principle and New Characteristic of Screw Oil Press
Operating Principle of Screw Oil Press
Oil bearing materials are feeded from hopper to pressing chamber, when the screw expeller pressing is running. Screw shaft rotates in the cage, which pushs the oil material into the machine for pressing. On the one hand, raw material keeps moving all the time in pressing chamber. Under the high pressure of pressing chamber, there is great friction drag between raw material and screw shaft, also between feedstock and press chamber. Thus the friction drag and relative movement emerge. On the other hand, the circle diameter of screw shaft root is gradually thickening and screw shaft distance is reducing little by little. When screw shaft is rotating, it pushes raw material strongly and rolls over outward at the same time. Thus there is relative movement among every raw material particle. The quantity of heat from friction drag satisfies technology in the pressing, which will contribute to thermal denaturation of protein in the material, and improve the oil extracting rate meantime. The screw oil expellers of big scale or small scale have similar theories during pressing process.
The New Characteristics of New Multifunction Oil Press:
1. High work efficiency, capacity up to 150-250KG per hour.
2. Better configuration, complete electrical device.
3. Vacuum filtration, more pure edible oil.
4. High oil yield.
5. Wide application: great machine for pressing more than 20 kinds of oil crops, such as peanut, sesame, rapeseeds, flax seeds, sunflower seeds, etc.
