Published: December 2022

Abstract
It is important to thoroughly analyze the separators that are widely used in cotton ginning enterprises today, the most common of which is SS-15A. Because these separators, which are widely used to date, cause damage to seeded cotton and the main product obtained from it, fiber and seed. Therefore, it is a very important current issue to identify ways to eliminate the above-mentioned shortcomings and introduce new improved separators into production. In this article, theoretical studies were carried out after installing a diverter on the cotton deaeration equipment. Invariability of air density and stationarity of air flow movement were also studied. As a result of the conducted scientific research, it was possible to preserve the natural properties of cotton in the separator.

Abstract
The article deals with the problem of using agricultural waste for biogas production. To create the material and technical base of agriculture, it is necessary to widely introduce new technologies for the use of agricultural waste, which account for a significant share of local renewable energy sources, comprehensive mechanization and automation of production processes, as well as specialization and cooperation at all stages. A promising direction for providing agricultural enterprises with cheap energy sources is the processing of biological masses and the production of biogas, the use of agricultural waste, waste from crop production, animal husbandry and poultry farming. Disposal of the aforementioned waste is a serious problem, and the use of biogas plants as installations for obtaining alternative energy resources is the most promising direction for their processing. The use of biogas plants as an alternative energy source is largely determined by their design properties and technological processes. A technological scheme for the use of waste based on an original biomethane plant is proposed, the implementation of which will solve the problem of the practical development of potential energy at least part of bioenergy resources, which is of great importance for the development of rural energy.

Experimental study of the polytropic coefficient for hydraulic shock from a decrease in pressure
Authors: Jonkobilov U , Rajabov U , Jonkobilov S 
Published: December 2022

Abstract
The article provides an analysis of scientific papers on the study of a hydraulic shock absorber - an air-hydraulic cap, shows that at present there is no consensus on the choice of the numerical value of the polytropic coefficient n. In practice, during the operation of pumping stations with long pressure pipelines, in the event of a sudden power outage, water hammer often occurs to the motors of the main pumps. To prevent this phenomenon, it is convenient to apply a hydraulic shock absorber. The accuracy of calculating the shock absorber depends on the reliable value of the coefficient n. The correct selection of the numerical value of the polytropic coefficient n provides for determining the optimal dimensions of the proposed hydraulic shock absorber. There are different opinions about the choice of the numerical value of n among scientists. N.E. Zhukovsky, when calculating the hydraulic shock absorber, takes n = 1.41. V.S. Dikarevsky accepts n=1.0. Therefore, the rationale for the correct choice of the numerical value of the polytropic coefficient for calculating the absorber in the case of water hammer is very relevant. The paper presents the results of experimental studies of the polytropic coefficient n in a hydraulic shock absorber from a decrease in pressure. When conducting experiments on the study of the absorber, modern scientific instrumentation was used. At the same time, the obtained results of the experiments confirm that the variability of the value of the polytropic coefficient during hydraulic shock in the cap and the correctness of the recommendation of D.A. Fox. The conducted studies prove that the polytropic coefficient has a strictly polytropic character.

Published: December 2022

Abstract
At present there is no grain processing machine capable of performing all operations on the processing of grain material. Therefore, a grain separating and throwing machine capable of processing grain material in a single operation is being developed. The machine performs grain material drying, its cleaning from impurities and cooling in the air flow. Theoretical studies were carried out to determine the basic design, geometric and technological parameters of the grain separating and throwing machine. By methods of mathematical analysis, the equations of grain motion in grain throwing machine and in the air stream were obtained. In order to confirm the theoretical expressions and data, experimental research on the laboratory setting was carried out. Experimental studies confirmed the adequacy of the theoretical conclusions. This machine can be used in the new technology of in-line grain material processing. The use of grain separating and throwing machine in the in-line processing of grain material will reduce the cost of grain processing.

Published: December 2022

Abstract
Film-forming mixtures based on reconstituted solutions of whey protein concentrates (WPC) with a protein content of 2.0 and 5.0% were subjected to UV irradiation in the range from 90 to 150 J/ml. With an increase in the dose of UV irradiation in film-forming solutions, the solubility of the protein decreased, the greatest effect was achieved in a mixture with a protein content of 2.0%. The decrease in solubility indirectly proved the process of aggregation of protein molecules in the studied solutions. It has been shown that UV exposure improves the strength properties of protein films. The highest specific stress at film rupture at an irradiation dose of 150 J/ml was 23.11 MPa in a 5.0% protein solution and 5.74 MPa in a 2.0% solution. The indicator of the applied force increased more intensively when processing a 5.0% protein solution, and amounted to 16.00 N in the case of a 2.0% solution, and 24.82 N in a 5.0% solution.

Published: December 2022

Abstract
Extraction efficiency is determined by mass and heat transfer processes in the liquid-solid system. In order to determine the optimal conditions for the extracting process, it is necessary to make up a mathematical model which reliably describes mass and heat exchange processes. In our study there are equations of mass and heat transfer, which occur during extracting process. They allow to determine numerically the process parameters and describe the resistance shares of external mass transfer much easier than in other methods of calculation. Further development of the outlined ideas leads to a new content of the concepts of kinetic coefficients of mass and heat transfer. To prove the accuracy of the calculation method, the share of external mass transfer resistance was calculated when extracting soybean oil with extraction gasoline and dichloroethane. The described calculation method for extracting process features may be used for designing extraction equipment, technology development and technological characterizing of process. Taking into account the identified system features, it is possible to reduce the solution to a particular form and mathematically describe a specific mass and heat exchange process. This makes it possible to determine the optimal conditions and increase the efficiency of the extracting process.

Published: December 2022

Abstract
Currently, the search for alternative sources of raw materials for the production of ethyl alcohol and related food and feed products is becoming increasingly relevant. One of the promising sources is jerusalem artichoke (topinambur). This crop has a high yield, is unpretentious, rich in polysaccharides. One of the problems in the production of ethyl alcohol from jerusalem artichoke tubers is the effective conversion of raw material polysaccharides into sugars digestible by alcohol yeast. Considering the seasonality of this crop and the difficulties in storage, it is necessary to integrate the technology of its processing as much as possible into the conditions of existing plants for processing grain raw materials into alcohol. The paper considers the most common options for water-thermal and enzymatic treatment of grain mashes in the production of ethyl alcohol in relation to Jerusalem artichoke. At the same time, it was shown that the highest results, with an alcohol yield of up to 98 liters per 1 ton of Jerusalem artichoke, are achieved when the mass is processed according to a mechanical-enzymatic scheme at a temperature of 90-95 °C using inulase enzyme for saccharification.
