Oil press oil press law, is the traditional fat preparation methods. With advances in technology to take the oil, has produced a human virgin soil, hydraulic machine press, screw press press press law three types of oil. Mechanical widely used today, is screw press, and hydraulic machines are still using. Screw press is widely used at home and abroad in recent years, more advanced continuous press to take the oil equipment. It is compared with the human press, hydraulic press juice (ie hydraulic press) and other equipment, has the following advantages: processing capacity, continuous production, labor intensity, the oil rate. Screw press for a variety of oil in oil, such as canola, soybean, cottonseed Renhe rice bran and so on. In particular, the need to maintain its original natural flavor or performance characteristics of some of the oil to take the oil, such as oil seed, sesame, cocoa beans and castor beans, etc., but also take the oil using a screw press.
Oil extraction process, the prepared clinker is treated embryos and placed under high pressure conditions, so that the grease is contained continuously extruded, and the pellets were press the cake formation process. When oil, reflecting the effect of taking the oil index call out the oil efficiency, refers to squeeze the fat percentage of the total oil content of oilseeds.
Necessary conditions affecting the oil effect, the amount of pressure inside one press. When the oil, the greater the pressure, the oil is squeezed out comparatively more, but it also requires a sufficient retention time. Second, the level of viscosity of the oil is squeezed. Press process, the lower the viscosity of the grease is squeezed out when the oil faster the speed of the press. Usually maintained pressed to lower the viscosity of the bore ju. Third, the size of the embryo material porosity. When squeezed, the more the pressure feed hole embryos. Gap gets. Grease the distance from the surface of the pressed cake should be...
