BTMA-Working principle of screw oil press ?

Screw oil press plays an important role in the process of oil making in the market, and our oil press is very great of quality and works very well,but many customers are curious about how the oil presswork.

Today we will analyse the working principles for you.

When the screw oil press is running, the processed oilseeds enters the press chamber from the hopper. The raw material is continuously pushed inward by the squeezing screw for squeezing. Since the material embryo is in motion in the press chamber of the oil press, under the condition of high pressure in the press chamber, a great frictional resistance is generated between the material embryo and the snail, and the material embryo and the press chamber. It can cause friction between the micro-materials of the embryonic material and cause relative movement.

On the other hand, because the diameter of the root circle of the snail is gradually increased and the pitch is gradually reduced, when the snail is rotated, the thread-strengthened blank can be pushed forward and turned outward, and it is close to the screw thread at the same time. The surface material layer also rotates with the press shaft. In this way, each embryo particle in the press chamber does not move 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 for the operation of the oil extraction process, helps to promote thermal denaturation of the protein in the raw material, destroys the colloid, increases the plasticity, and also reduces the viscosity of some oils, which is easy to precipitate. Improve the oil output rate of the oil press, so that the oil in the material is squeezed out and flows out from the gap in the circular row
