Screw oil press working principle After the material embryo into pressing chamber, under the action of squeeze screw thread rotating, feed end to the bread end direction gradually propulsion. Due to the squeeze screw thread bottom diameter changes from small to large, makes squeeze interior paragraphs volume reduced gradually; And because pressing screw thread continuously makes material embryo push pressing chamber, so in the condition of front resistance and behind push produce pressure, compression material embryo, made the oil squeeze out. At the same time adjust the DAYU oil press cake clearance to change the thickness of the bread, the gap is more smaller, the cake is more thin, /standalone-oil-press-machine.html oil press machine squeeze interior pressure is also more bigger. In addition, the material embryos in pressing interior present motion state, cause between material embryo and the strip row, material embryo and squeezer, material embryo and the DY-6YL Screw Oil Press material produce friction, and produce a lot of heat, make the material embryos temperature rise in pressing interior, so that in favour of material embryo oil outflow, improve the yield efficiency. Before material embryo into oil press squeeze, must be passed a pretreatment process, pretreatment quality will directly affect the oil press normal work and wheat flour mill oil extraction rate.
