In the press process, pie throwing radially different levels of oil content, oil content in the surface layer than the outer surface of the story, while the difference between the price of Zhengzhou press, squeeze the material between the rate of radial level as the resid virgin material goes to the cake mouth decreases. The actual radial from the plane of cake residual oil rate level was just the opposite relationship, that cake residual oil is higher than the outer lining of residual oil. This phenomenon can be considered due to the screw press due to the structural characteristics: on the one hand pressed cake blank check within bore drain is bound to the surface along the helical axis virgin material passage is long and difficult to discharge; another in terms of the material layer is thicker feed section and the front section of the press section, prone to oil ratio gradient in the late squeezing, pressing thin material is compressed Zhengzhou press, while close to water evaporation at the surface of the screw shaft strength than virgin high cage at the wall, so that the material will be squeezed out of oil particles in the pores, so the oil content of the cake layer gradient between the inner and outer relatively narrow; when the outside when the pressure disappears rapid evaporation of oil press factory in Zhengzhou, water cake discharge machine and an outer layer cakes, fat suction, etc. but the inner layer cake oil content is less than the outer layer. For any type of press (pre-press or a press), virgin plastic material most suitable for steaming and roasting through to achieve. The plasticity of virgin material with the formation of its moisture and temperature, if cooked pressed into billets with inadequate moisture and temperature, will cause discomfort Zhengzhou cooked blank plastic press brand, resorted to the oil effect worse. If cooked blank plastic lower particle binding loose when the press, the formation of dry hard, with high crude blocks in the form of powder or cake from the plane, the oil flow toward the mouth of the cake, but also a significant increase in pressing machine load. If cooked billet to plastic due to excessive wetting a significant increase in the press a lot when cooked particles from the cage bars blank gap extrusion, while cooked blank tile massive cake can not be formed, but in the amorphous plastic exhaust, oil flow towards the feed zone, and the motor load is reduced.
