When the fuel into the oil press virgin bore, with the pressing chamber rotates, the pressure increases. As the seed material extruded continuously squeezing oil, virgin material particles in direct contact with each other and cause a pressure deformation of seed material, particularly in the oil film rupture and the adhesive body. Food dehydrator bore after being squeezed, squeezed material is not a loose body to form a plastic body, called the cake. Squeeze due to the dual role of temperature and pressure, will continue to deteriorate protein, thereby affecting virgin plastic material, in short, in order to ensure an appropriate level of protein denaturation best squeeze out the oil effect.
Peanut oil is a high amount of crop, its internal fat in spherical or particulate present in the cell membrane by a layer of closed, surrounded by the outside world in the extrusion process, with this film and cell wall rupture, peanut oil cracks in the flow begins; in the extrusion process, the extrusion part peanut oil, peanut becomes brittle and hard, oil equipment elasticity; the peanut skin contain more fiber, the applied stress, and peanut. separated from the surface, so that the peanut skin off easily; in the extrusion process, peanuts and not by the shear stress, so no broken kernel phenomenon, it is easy to restore the status quo;
Fat content according to the requirements of different pressures are applied. Defatted peanuts obtained different results.
