Structural properties of virgin material depends on the composition of the oil itself and the following pretreatment. 1, the number of pressing compound was destroyed cells more the better, it is a good oil. 2, virgin material particle size should be appropriate. If the particles are too large, easy skinning closed circuit, is not conducive to the oil; if particles too small, is not conducive to the oil, because the press will take away the fines, increased oil flow resistance, or even blocked passage. While fine particles will increase the virgin plastic material, is not conducive to the pressure increase. 3, virgin material density without compromising the internal and external structure of the bigger the better, this will help increase the amount of processing equipment. 4, virgin material have proper moisture, better mobility. Pressing the material to have the necessary temperature to minimize oil feed juice viscosity and surface tension to ensure good fluidity of the grease in the whole process of the press. 5, virgin material particles have sufficient plasticity. Pressing the material must have a certain plasticity range. On the one hand, it shall not be less than a certain limit, to ensure complete particle considerable plastic deformation; on the other hand 230 press, the plastic can not be too high. Otherwise virgin material mobility, easy set up pressure, there will be time squeeze "crowding out" phenomenon, adding unnecessary material back. 230 press at the same time how much high plasticity, early automatic molding press 230, in advance of the oil, easily into hard cakes and unfavorable oil, and oil quality is poor. Large screw press expeller cage is also equipped with a blade, scraper mouth pressed deep bore 230 press good operation, the alignment of each pitch circle, to prevent the preform pressing bore slip in and prevent back blank, with to adjust the cake thickness, thereby pressing the corresponding control the chamber pressure to reduce residual oil rate. In addition, it also enables the smooth surface of the slag cake burger institutions, and often with steaming wok, fried and steamed oil can press continuously. 230 press price _230 _ sesame oil press machine is provided by the source Machinery Co., Ltd.
