Automatic Temperature Control Spiral Oil Press
Because the root screw diameter is garden gradually thickening, the pitch is gradually reduced, so when the screw rotates, the thread is hard blank will move forward, and turns outward, and near the screw thread surface layer with shaft rotation. Thus, each particle in the cylinder does not move in the same direction as the velocity, but rather there is relative motion between the particles. The heat generated by friction and meet the required oil process of heat, contribute to the protein thermal denaturation to blank, destruction of the colloid, increased the plastic, but also reduces some viscous oil to precipitate easily, thus increasing the oil press oil yield, the squeezed oil material the oil pressure, and from the garden and a row row gap gap outflow.
