The technological process of vegetable oil production requires significant energy costs, while the introduction of new technologies requires investment, which is a challenge for small and medium-sized enterprises in the current environment. This makes it important to introduce energy-efficient equipment in the conditions of these enterprises, which does not require significant investments. The article was concerned with improving the technological process of pressing oilseeds by introducing an energy-efficient oil press into the technological process and studying its structural and kinematic characteristics. In the context of the study, the determination of the physical and mechanical properties of raw materials, methods of theoretical mechanics and solid mechanics, calculation of structural elements of technological equipment for processing oilseeds were used. The necessity and expediency of theoretical analysis and experimental research are substantiated. The main regularities of oil separation from the crushed mass are determined. The study of physical and mechanical characteristics, size and weight parameters of seeds and crushed mass allowed to substantiate the main kinematic and design parameters of the screw press. The principle of operation of an energy-efficient screw oil press is described. The design of the press is improved by a steam sprayer installed in the receiving hopper under the threaded rollers, which is equipped with a steam generator, which makes it possible to carry out moisture-thermal treatment with steam within one device. The proposed constructive solution includes: determination of the coefficient of friction of seeds on an inclined plane, study of the components of the crushed mass obtained with the help of an energy-efficient oil press, and theoretical aspects of oilseed pressing. A study of the design and operating parameters of the screw press has been carried out, namely: determination of the screw press productivity, use of an energy-efficient press for oil separation makes it possible to improve the quality of the technological process, determination of the press power consumption and its efficiency. It has been concluded that the improved design solution of the press meets the modern requirements for oil production machines. The use of the proposed constructive solution will reduce oil losses during pressing, which will significantly increase the efficiency of the process, reduce operating costs and promote the development of oil production in small and medium-sized oilseed enterprises
