Problem statement. The production of oil crops and products of their processing has significantly increased in recent decades. Vegetable oils are mainly produced by pressing oilcontaining raw materials using screw-type presses. During the press operation, there is a need to adapt its working regimes to the seeds of individual crops while ensuring the possibility of adjusting certain operation parameters that are set technologically. Purpose. The main purpose of the present research consists in analyzing the design peculiarities of the enhanced screw-type press for extracting oil from different oil crops and oil-containing raw materials. In addition, there is set a goal of analyzing the screw for stresses and strains. Methodology. The finite-element method integrated into the SolidWorks software is used for analyzing the stress-strain state of the pressing screw at the hardest loading conditions. Results. The obtained results are presented in the form of the stresses and strain distribution along the screw shaft and flights. The corresponding 3D and 2D stress-strain diagrams are plotted and thoroughly analyzed. Originality. The zones of the screw overloading are defined and the possibilities of providing the screw reliability and durability are considered. Practical value. The proposed design of the screw-type press can be implemented in practice for performing pressing operations while extracting oil from different oil crops and oil-containing raw materials. The results of testing the screw stress-strain state can be used for predicting the screw reliability and durability at the stage of its designing. Scopes of further investigations. Further investigations on the topic of the present research can be focused on deriving the mathematical model describing the force and pressure conditions applied to the screw shaft and flights

“…Most often, the actual task in the design of oil presses is to create universal machines for squeezing oil from almost all types of oil-containing crops (with an oil content of at least 20-15%) (Mushtruk et al, 2020;Lara-Ojeda et al, 2021). The re-equipment of the press by replacing individual parts (screw nozzles, seer slats, yield nozzles in the press matrix, etc.)…”

The relevance of the study is due to the problem that is characteristic of various types of screw press structures, which leave up to 16% of the oil in the cake when pressing sunflower oil. In this regard, the purpose of this study is to find rational methods to improve the design of twin-screw extrusion presses to increase the oil yield. The leading methods for solving this problem are empirical research methods that allow comprehensively considering the stages of improving the geometric configuration of the screw shaft based on observation and finding a rational solution to the problem by measuring and experimenting. The paper analyses the features of technical means for grinding oil-containing raw materials in presses and extrusion presses, justifies the need to develop new grinding working bodies. The need to supplement the existing ideas about the interaction of special grinding working bodies with transport and compressive screw nozzles and the development of grinding units for twin-screw extrusion presses produced in Ukraine are clarified. Experimental studies were conducted with the developed design of new working bodies – cylindrical-conical nozzles. They create an intermediate compression of oil-containing raw materials, aimed at intensifying grinding with simultaneous mixing of the processed oil-containing material. A triple repetition of the increase in the degree of compression was obtained when installing three pairs of cylindrical-conical nozzles along the length of the screw shaft. Their use allowed for intensifying the degree of pressure increase and the additional oil yield of up to 3.1%. With each processed ton of seeds, due to the increase in the amount of pressed oil, the profit of enterprises that will improve twin-screw extrusion presses with these working bodies will also increase accordingly.
