The work principle of oil press:

Oil Press operation, enter the press bore well processed material from the hopper. In the screw axis of rotation, blank continuously pushing, pressing oil. On the one hand, the root circle diameter of the helical axis gradually thickening, pitch decreases gradually, so that material progress in the squeezing chamber, volume are compressed, pressure is increasing continuously, meet the fat separation required pressure. On the other hand, by constantly stock movement in the press the squeezing chamber, in the press bore pressure conditions, the friction resistance greatly between blank and screw, blank and pressing chamber; at the same time the thread that stock in advance at the same time, we turned outwards, material layer can close to the screw thread surface rotates with the shaft, so in the squeezing chamber for each blank particles are not the same speed, direction of movement,oil press machine

‍ but also has the relative motion between the particles. The heat generated by the movement and meet the required oil process of heat, contribute to the protein thermal denaturation makes material embryo, destruction of the colloid, increase the plasticity, reduce oil viscosity, which makes it easy to precipitate, thus improving the oil press oil rate‍
