Summary. There are two methods pressed vegetable oil - cold and hot, preference was given to the second. In hot pressed from the original oilseeds pressed out most of the oil. Vegetable oils are not only concentrated source of energy, but they also contain a number of essential nutrients for humans. The article presents the dependence of the performance of screw oil press on the geometric characteristics of the screw oil press, as well as the physicochemical properties of the source of oilseeds. To determine the properties of the oil press equipment was analyzed according to the design characteristics of the process parameters pressed vegetable oils by hot pressing with subsequent optimization. The data on the experimental studies of changes in physical and mechanical properties of the molded oilseed material as it passes through the screw oil press. As the material used oilseed rape seeds. In experimental studies have identified the following principal kinetic changes occurring along the length of the screw shaft: mount compressible material; bulk density of the material; humidity compressible material; theoretical values volumetric productivity; actual volumetric efficiency; theoretical compression ratio; the actual degree of compaction and the degree of change of the actual compression along the length of the screw shaft relative to the material located within the first turn of the screw and the bulk material on the sites of use of the penultimate turn of the screw shaft to the output. Treatment of experimental data, that the performance depends on a combination of oil press design parameters of the screw shaft cereal chamber and the physicomechanical properties of the molded material.
