The principle of plant oil press

oil processing in operation, the preform processed into the hopper, oil from the hopper into the press bore. Screw a screw to in advance by pressing, the preform is in running condition in the press the squeezing chamber, in the squeezing chamber under conditions of high pressure, friction force between the blank and many of the screw, the press bore. The main is to make the friction material blank and blank, resulting in relative motion. On the other hand, root diameter screw is gradually enlarged, when the screw motion, thread the preform can move forward and can be turned outwards, material layer and near the screw thread surface with the pressing shaft to rotate, so that the oil plant chamber in each blank particles are not equal with Fang Xiangyun. The particles also exist between the relative motion. There is friction heat and meet a heat required for oil of process operation, help to promote the protein thermal denaturation of billet, destruction of the colloid, increased the plastic, but also reduce the oil viscosity, easy to press out the oil, thus improving the oil press oil rate.
