Published: December 2021

Abstract
This article presents the results of research to determine the basic geometric dimensions of a drum sorting machine designed for potato sorting. A critical analysis of the current situation in this area has been carried out. A number of research works have been studied aimed at developing special methods to reduce manual labour and improve the quality of sizing and sorting potatoes. At the same time, it is important to sort by size with a low level of product damage, with high productivity. Known mechanical and robotic machines used for sorting potatoes: roller, drum, conveyor (belt) and combined. And also, with the help of machine and computer vision, laser backscattering of light, ultrasonic, visual and spectral analysis systems, optical, acoustic intelligent sorting systems. Among the mechanical ones, the drum sorting machine is the simplest in design. The disadvantage of this machine is that during operation the product to be sorted is only in the lower part of the drum, i.e. only part of the work surface is used. To eliminate the abovementioned disadvantage, a new design of the machine is recommended. Where the sorting surface is made of elastic mesh, the size of the holes increased in the direction of movement of the ends along the sorting surface. The ends are connected and pulled together on two drums. The holes of the elastic mesh material vary in size, the size of the holes increases from the beginning to the end of the sorting surface. The drum can be in a truncated cone or a cylinder shape. To ensure the efficient operation of the proposed machine, mathematical calculations are derived, including geometric and kinematic parameters.

Estimation of the stability of a fishing vessel during purse seining
Authors: Ivanovskaya A V , Bogatyreva E V 
Published: December 2021

Abstract
One of the reasons for the emergency of a fishing vessel, as well as for the failure of fishing equipment, is the sudden tension of the purse rope, which occurs when the fishing equipment is pulled. As a result of the loss of stability the vessel may enter the encircled seine area and even capsize. There are a number of measures to improve stability during the operation of the vessel. However, when designing fishing equipment, it is necessary to know forces acting on the vessel from the seine side. The article presents a method for assessing the static stability of a vessel with a static application of the tension force of the purse rope. As a result of the study, an expression for determining the static heel angle using a three-dimensional representation of the vessel is given. During simulation the geometrical parameters of the purse rope in the process of purse seine were taken into account. The tension force of the purse rope is also presented as a variable.

Authors: Agafonychev V , Makhonina V , Roslikov D 
Published: December 2021

Abstract
Convective drying is a common method of dehydration of meat snacks (chips), which largely forms the competitive properties of the finished product. The kinetic parameters of drying (for example, the change in moisture and mass of the drying object during the process, the intensity and duration of drying) are the basis for the development and selection of equipment for the drying section of the industrial production of dehydrated meat products and process control. These indicators were determined experimentally, since they largely depend on the physical properties of a particular drying object, and it is not yet possible to calculate them with an accuracy sufficient for engineering practice. The kinetic parameters of convective drying of salted samples in the form of plates with a thickness of 2, 3, 4, 6, 8, 10 mm, made of chicken fillet meat blocks, have been determined. In order to ensure the adequacy of the research results to the conditions of industrial production, the main stages of the industrial technological process and the characteristics of the raw material samples were physically modeled: the composition of the curing mixture, the dimensions and physical properties of the raw material samples, and drying modes. The presence of complete volumetric evaporation during a period of constant drying rate of samples of raw materials with a thickness of 2, 3, 4 mm was revealed, as well as partial volumetric evaporation (about 90%) for samples with a thickness of 6, 8, 10 mm. A change in the physical mechanism of the drying process in the period of decreasing speed (cessation of volumetric evaporation and a multiple decrease in the intensity of evaporation) has been established. Dependences of the duration of the complete drying process (the sum of the periods of constant and decreasing speed) on the thickness of the raw material samples have been determined (for example, a 4 mm thick sample dries 25% slower than a 2 mm sample). Based on the research results, the possibility of increasing the productivity of the drying equipment (up to 60%) and optimizing the drying agent supply system to the drying object is shown.

Abstract
The purpose of this study is to identify the main trends in the agro-industrial complex development of the Russian Federation, substantiate the organizational and economic recommendations aimed at stimulating Russian agricultural production and enhancing of this economy sector competitiveness. An extensive corpus of empirical data reflecting the agro-industrial complex development in the Russian Federation in 2016-2020, as well as its place in foreign trade operations of the Russian Federation has been thoroughly studied in frames of this research. Using the tools of statistical data processing (sampling, observation, summary and grouping), the methods of econometric analysis, the dynamics of agro-industrial complex products manufacturing, the rate of the main indicators’ change, the place of agro-industrial complex in export-import operations of the Russian Federation have been revealed, the main indicators have been compared. The geographic conditions diversity of the Russian Federation, combined with a wide range of climatic features, the availability of land and water resources creates favorable conditions for productive agricultural activities. It has been established that large-scale agricultural producers dominate in agro-industrial complex of the Russian Federation. The directions of agro-industrial complex, in particular, crop production and cattle rising, are unevenly developing in the Russian Federation. The constituent entities of the Russian Federation, which administratively represent the Southern Federal and North Caucasian Federal Districts specialize mainly in the cultivation of grain and oilseeds due to the natural and climatic factors’ action. State authorities of the Russian Federation successfully implement the tools to stimulate agricultural production, in particular: preferential taxation regime, subsidies for lending to the agro-industrial complex economic entities from the state budget, leasing development, etc. The state support mechanism effectiveness can be intensified by using the organizational and economic tools substantiated by the authors.

Published: December 2021

Abstract
The article describes a comprehensive analysis of agrochemical and soil erosion monitoring data, using the example of the Alekseevsky district of the Belgorod region with the use of a geoinformation system. The GIS automatically generates tables with data grouped by various characteristics: soil type, degree of erosion, slope steepness and exposure. The content of mobile forms of phosphorus and potassium, organic matter, and the level of soil acidity in the context of the district in areas with different exposures, the degree of erosion and the steepness of the slope was analyzed. The most productive soils are located on the plain, followed by the slopes of the northern exposure, neutral, then southern. Erosion processes occur more strongly mainly on the slopes of the southern exposure, and the northern slopes are characterized by humidity. Down the slope, the nutrient content decreases, the level of soil acidity increases.

Abstract
Based on the identified trends, patterns and features of the development of the grain production industry in Ryazan region, a conclusion was made about the existing potential and the prospect of support for agricultural organizations specializing in the production of grain, the development of seed production of winter wheat and spring barley, the use of innovative technologies for their cultivation and harvesting. The team of authors revealed that one of the main problems in the development of the grain production industry both in Ryazan region and in Russia was a decrease in the level of technical equipment of agricultural enterprises with modern grain harvesters. To solve this problem, it is proposed at the level of the regional government to purchase a license from developers for the production of devices that reduce grain losses during threshing and cleaning, create jobs for the production of these devices and modernize grain harvesters in the region, that will allow getting a larger percentage of high-quality food and seed grain, to replenish the regional budget with an additional amount of taxes, the receipt of which will exceed the costs of purchasing a license and organizing additional jobs.

Published: December 2021

Abstract
The article presents the basics of the functioning of information and measurement systems for optimizing the process of processing wheat grain. The quality of grain processing products is influenced by climatic factors and grinding technologies. The modern development of information technology makes it possible to modernize information and measurement systems for grain processing and developing algorithms for analyzing the grain physical characteristics. Trial grinding of wheat grains by different varieties was carried out at a laboratory mill. The obtained mathematical models made it possible to predict the quality of grain separation in separators. Digitalization of the grain processing industry includes the use of artificial neural networks for the analysis of images of grain mass by computer vision algorithms using the developed software. It is promising to increase the information content of granulometric analysis through the use of modern intelligent systems. To classify wheat by milling properties, it is proposed to use the grain hardness index. Computer vision and artificial neural networks were used to find and systematize grain grinding particles according to geometric properties. The error of the estimation for the hardness is no more than 3.5 %.

Abstract
The Russian Federation has a significant raw material, scientific, technical, production and consumer potential necessary for the development of the mineral fertilizer industry. The amount of fertilizers used to increase soil fertility is one of the factors that determine the solution to the problem of the country’s economic and food security. The purpose of this article is to develop a methodology for assessing the impact of the chemicalization process on the collection of major agricultural crops in the Russian Federation. To write it, methods such as: correlation and regression analysis, index analysis, calculation of the integral indicator, forecasting are used. The novelty of the conducted research lies in the following sequence of actions. Based on the statistics, we performed an index analysis of seven parameters; calculated an integral indicator that allows us to consider factors with a heterogeneous metric; assessed the impact of the chemicalization process on the collection of major crops. Further (using the Excel program), we developed a forecast for the development of chemicalization processes in agriculture until 2022 according to three scenarios: optimistic, probabilistic and pessimistic. Forecast quality indicators indicate that the optimistic and probabilistic scenarios are more likely to be realized. Thus, based on the obtained forecast data, it can be stated that it is necessary to adjust certain indicators that actively influence the rate of harvesting of the main agricultural crops, which is a mathematical justification for making managerial decisions in the development of strategies and programs for the chemicalization of agriculture in the Russian Federation, in order to develop it further.
