At the same time, it should be taken into account that specific botanical varieties grown in different geographical regions have an individual chemical composition that determines the intensity of the ongoing oxidation processes, therefore nuts of different batches have different potential for storage. The lack of a system of traceability of purchased nut batches at the stages of production, logistics and sale, as well as the lack of objective methods for assessing the potential level of preservation, which leads to the incorrect establishment of the expiration dates of walnuts, and as a result, more than 30% are sold in trade networks walnuts with signs of bitterness.\u0000The quality of nuts during storage depends mainly on the moisture content, storage temperature, relative humidity, oxygen content level, commercial type of nuts, packaging materials, storage form and type of technological processing of nuts (without shell, in shell, fried, etc.). Nuts are products of long-term storage.\u0000The purpose of the research is a comprehensive analysis of the operation of modern convective dryers of agricultural raw materials and the determination of ways to improve them to ensure high-quality and uniform drying.\u0000According to the results of the analysis of the existing drying units, their disadvantages and advantages were determined.\u0000The peculiarities of the application of hopper dryers in various production lines among industrial goods, food products, and construction materials that require mixing of bulk products are analyzed. The use of these dryers has shown high reliability in operation when drying significant volumes of raw materials, absence of stagnant zones, high efficiency of the process and automation of the entire technological process of drying.\u0000In order to intensify the process of convective drying, it is necessary to improve the heat and mass transfer both inside and outside the raw material, an increase in the drying temperature will inevitably lead to overheating of the product and loss of biologically useful substances, so one of the ways to increase the drying speed can be the use of mixing devices and devices , installed inside the drying chamber.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124652903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of the article is to study the operation of the hydrostatic transmission in the braking mode. The calculation scheme of the GST-90 hydrostatic transmission was developed and its mathematical model was developed, which adequately reflects the processes occurring in the hydraulic transmission of the grain harvester in braking mode.

Currently, the theoretical issues of the dynamics of piles when they are immersed in the soil have not been developed to the extent required by practice. The primary task here is to study the process of sinking the pile into the soil in order to achieve the required depth of immersion with minimal damage to the structure of the pile itself, and for it to perform the work that is set before it.\u0000Naturally, in the process of sinking piles into the soil, not only elastic, but also viscous, plastic properties of the soil are manifested and its destruction occurs. The theoretical tasks of sinking the pile into the soil, taking into account the viscous, plastic properties of the soil environment and the deformation characteristics of the pile material, have not been investigated.\u0000Nowadays, in connection with the circumstances that are currently happening in Krane, in the Vinnytsia region, the percentage of people's involvement in agricultural affairs is growing significantly, namely: in the planting of new garden and grape plantations and lands.

This is connected both with the development of theoretical approaches that allow to model the behavior of the latter with high accuracy, and with a significant increase in reliability and a decrease in the cost of power semiconductor technology, which in turn made it possible to improve operational characteristics and reduce the cost of such systems as a whole. The consequence of this trend is that asynchronous motors are increasingly used not only in classic electric drive systems with easy starting conditions, but also increasingly used in traction electric drives and electric drives with large starting moments, which were traditionally implemented on the basis of direct current motors. This circumstance leads to the appearance of additional technical difficulties in the design and operation of asynchronous electric motors, which is associated with the peculiarities of their natural mechanical characteristics, which have a slightly underestimated value of the starting torque. And although this shortcoming can be eliminated by increasing the power reserve of the engine when designing the electric drive, such a compromise solution will have significant disadvantages associated with a decrease in efficiency and an increase in the cost of the electric drive as a whole. It is obvious that this circumstance determines the need for further theoretical research aimed at improving the starting characteristics of asynchronous motors.\u0000Considering what has been said, today the induction motor remains the most common electric machine used in various fields of activity. Moreover, the share of asynchronous motors used in industry is growing rapidly, and the scope of their use is constantly expanding. A. therefore, the development of a mathematical model of the dependence of the starting torque on the angular position of the rotor, which in the future would allow improving the starting characteristics of asynchronous motors, is an urgent scientific and applied problem that has significant practical value.\u0000In the article, the equation of the dependence of the starting torque of an asynchronous motor on the initial position of its rotor is obtained, which makes it possible, taking into account the design features of the AD, to uniquely calculate the value of the mechanical torque that occurs on the motor shaft when it is started with the nominal supply voltage. The mathematical dependence of the deviation of the AD starting moment on the initial rotation angle of the rotor was obtained, which can be used as a corrective mathematical model of the AD control system. The simulation of the dependence of the torque of an asynchronous motor on the initial position of its rotor was carried out, which made it possible to confirm the adequacy of the obtained mathematical dependence. It is shown that the change of the starting torque ","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121940776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further development of the processes is possible through the development of new technological schemes based on the analysis of deformation kinematics and the appointment of favorable technological parameters, taking into account their influence on the stress-strain state and deformability of the material of the workpieces. In order to widely use the method of assessing the deformability of workpieces, a reliable technique is needed, which provides for the presence of a mathematical model of the trajectory of deformation of material particles in the coordinates \"stress state indicator - accumulated plastic deformation before failure.\" The work uses an approach to finding an analytical representation of the deformation trajectory based on the construction of a differential equation between the components of plastic deformation increments, followed by the solution of this equation and the identification of its parameters based on experimental data. According to the results of the research, the deformation trajectories of the material particles of the peripheral surface of the flange when planting by rolling stamping method were schematically constructed in the coordinates \"intensity of deformations - stress state indicator\". Based on the built model, damage accumulation can be simulated by changing the values of the model parameters for different materials and deformation paths. An analytical representation of the deformation trajectory in a parametric form was obtained. The advantages of representing the deformation trajectory in the form of parametric equations are the convenience of analyzing these trajectories. The advantage of the model of the trajectory of deformation of material particles in the coordinates \"stress state indicator - plastic strain accumulated before failure\" is the absence of a material constant in the analytical expression for the stress state, and the consequence is additional convenience of analyzing ratios and selecting the value of the material constant based on experimental data.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121398397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of renewable energy sources in energy production is constantly growing, and the issue of increasing the share of renewable sources in the energy balance of each individual country is currently relevant. In the supply of primary energy, the share of renewable energy accounts for 19% on a global scale. Of these, biomass accounts for 10%, or 258 million tons per year, i.e. in the world, biomass provides the largest share of energy supply from renewable sources. Domestic agricultural enterprises are significant consumers of fuel and energy resources, therefore they face an objective need to use alternative energy sources, including biological types of fuel and the introduction of innovative energy-saving technologies. Biogas production is an efficient and investment-attractive technology due to the presence of significant raw material potential, favorable natural and climatic conditions, etc. However, the level of introduction of this type of energy in the agricultural sector is insufficient, which is related to a number of issues, including the insufficient level of practical recommendations for choosing the power of electric energy generators, their number, operating modes taking into account the daily schedule of energy consumption, loading and optimal efficiency installations when providing autonomous power supply of the enterprise.

During hot deformation, the metal is also strengthened (hot defamation), but it is completely removed in the process of recrystallization. With it, the plasticity of the metal is higher, and the resistance to deformation is approximately 10 times lower than during cold deformation.\u0000Most metals have a recrystallization temperature that is half or one-third of the melting temperature of the metal. Therefore, we can say that when the metal is plastically deformed above the recrystallization temperature, but below the burning point, this is a hot process of metal deformation.\u0000Elastic and then plastic deformation occur under the influence of external forces on the material. Pressure treatment of metals is possible due to their plasticity. A sign of elastic deformation is its reversibility, that is, its disappearance after removal of the load. The physical essence of elastic deformation is explained by the slight relative displacement of atoms in the crystal lattice, which return to their previous positions after the load is removed.\u0000There are such methods of hot processing as: hot rolling, hot forging, hot stamping, hot drawing.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129068668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
