check the oil press law the basic principles of (1) Press process
The process of squeezing oil from that machine with the role of external forces, will be oil from the juice squeezed out of the course material. In the press process, the main physical changes are occurring, such as material deformation, oil separation, friction heat, such as water evaporation. However, because of temperature, moisture, micro-organisms and so on, but also have some biochemical changes, such as denatured proteins, enzymes and destroy the passivation, the combination of certain substances. When pressed, pressed particle materials under stress at the surface of each other both inside and outside the tight squeeze, with the result that some of their liquid and gel, respectively, have two different part of the process, that is, oil is expected from the juice was squeezed out of the gap and pressed to form a hard material deformation of particles cake.
