“…Seed moisture is a parameter that can be measured and changed as needed. An important factor in optimising the process of pressing oilseeds is to determine the most effective humidity indicator, at which the oil yield is the highest (Antoniassi et al, 2022). Based on the research of many scientific papers, the study (Bălțatu et al, 2022) concluded that there is an optimal humidity level for each type of oilseed.…”

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.

Over the last few years, vegetable oils have become an integral food part of the vast majority of the planet's population. In order to preserve all valuable substances in vegetable oils, it is necessary to correctly choose the rational parameters of the oil extraction process. The main purpose of this research is to analyze the influence of various factors on the quantitative and force parameters of the oil extraction process and substantiate the prospective directions of automation of the screw press operation. The research methodology is focused on mathematical modeling of the pressing process and analyzing the stress-strain characteristics of the pressed material (sunflower seeds and cake) at different operational conditions and design parameters of the screw. The obtained results are presented in the form of analytical dependencies of the press output (productivity), extraction pressure, and consumed power on the screw rotational frequency and screw flight pitch. The corresponding graphical dependencies are plotted for visualization of the obtained results with reference to the existing household press LiangTai LTP200. The conclusions on the prospective directions of automation of the screw press operation are drawn. Particularly, the necessity of regulating the temperature of the pressing chamber and extracted oil by means of applying additional heating and cooling devices is substantiated. As well, the sensors that monitor the mass of the extracted oil and the consumed current of the electric motor are proposed to be installed. The rotational frequency of the screw is suggested to be adjustable by applying the frequency converter controlled by the additional electronic system based on the data obtained from the sensors. The paper may be used by scientists and engineers working on designing screw presses and improvement of their performance characteristics. Further investigations on the subject of this research may be focused on experimental verification of the qualitative and quantitative parameters of the extracted oil depending on the type of the seeds or kernels to be pressed, and operational parameters of the press (screw rotation frequency, temperature of the pressing chamber, etc.).
