The working principle of oil press machine

oil press machine mill run, processed oil from the hopper into the pressing chamber.By pressing the spiral turn make the material in the embryo to advance, to squeeze.Because the material embryo in oil press in the bore of the press is in motion, under the condition of pressing chamber pressure, fodder and squeezer, embryo and had a great frictional resistance between pressing chamber, so you can make friction between embryo micro material, resulting in relative motion.On the other hand, due to squeezer root diameter is gradual enlargement of pitch is gradually reduce, so when squeezer turns, thread and material embryo that will move forward, can flip outward again, close to the material layer on the surface of the press screw thread at the same time also with pressing shaft rotation.So every embryo material particles in the bore in the press is not a constant velocity, the same movement, but also there is relative motion between particles.Produced by friction heat and heat necessary to satisfy the oil process operation, helps to material in the embryo protein denaturation, destroyed the colloid, increased the plastic, but also reduces some oil viscosity easy exhalation, thus increasing the spiral oil press, to squeeze out the oil from material, and article from row gap and the discharge gap flow out.
