Abstract
Drying (dewatering) of plant products is widely used in various technologies of their processing, transportation and storage. Existing dewatering processes and equipment are very diverse in design and application; their technical and economic performance also varies significantly. The effectiveness of the dewatering process of vegetable raw materials depends on the range of initial and final humidity and a number of physical, mechanical, chemical and other properties of the product, the drying method, technology and technical characteristics of the equipment. characteristics of the equipment. It is particularly difficult to ensure efficient, relatively low-energy drying of grain products, the seeds of which contain moisture in a bound form and are separated from the external environment by a dense seed shell. Currently, the volume of drying and processing of such seeds is increasing and amounts to millions of tons per season. Dried seeds are used to make flour, food additives, spices, medicinal oils and other natural products. The article studies the ways to reduce energy consumption in the main drying method-convective dewatering of commercial grain with low initial humidity. It is shown that the injection of small doses of microwave energy into the drying process - 1-5% of the total convective heating power - can reduce the overall energy intensity of the process by 25-27%.

Published: January 2022

Abstract
In the context of the country’s growing self-sufficiency in foodstuffs, including potatoes, commodity producers need to purchase potato harvesters and devices. The choice of potato harvesting equipment should meet the needs of agricultural producers (potatoes) while contributing to the improvement of agricultural performance. In this situation, enterprises are faced with the problem of choosing potato-harvesting equipment: cheap but low in productivity, or expensive but high-tech. To substantiate the choice of using machines for harvesting potatoes, it is possible to use the method of expert assessment, which allows choosing among a variety of alternatives, based on the preferences and justifications of experts. The use of the mathematical apparatus makes it possible to compare various physical characteristics by reducing them to a dimensionless scale. As a result of studying the most common trailed potato harvesters, the KKP-2M trailed harvester possesses the optimal ratios of the cost of the machine, productivity and quality of the resulting product. Trailed potato harvesters at a lower price have technical parameters that are not much inferior to self-propelled machines. This conclusion is confirmed by such methods as “Score table” and “Polygon for alternatives”. The first method provides a mathematical justification and the second one allows visualizing the resulting solution.

Abstract
The release of good-quality and safe poultry products depends on the sanitary condition, compliance with preventive measures and the development of technologies aimed at improving the safety of the products. Microbiological studies and meat quality indicators were determined using standard methods. A method of cooling in 0.01% solutions of HIT AseptoDes has been developed to control the contamination of the cooling medium and prevent microbial contamination of the surface of poultry carcasses. It has been shown that to reduce microbial contamination and decontamination of the surface of carcasses from Salmonella, 0.02% solutions of the agent can be used with a cooling time of 25 minutes and 0.01% solutions with a cooling time of 35–40 minutes. The quality indicators of meat of carcasses chilled with solutions of the studied product, in comparison with carcasses chilled in ice water, do not differ significantly, with the exception of the acquisition of the surface of the carcasses of a paler color. It was found that after 6 hours of storage, the presence of a residual amount of peracetic acid in washes from carcasses was not detected.

Abstract
The studies on the comparative assessment of soybean varieties of Siberian breeding performed in 2017-2019 in the sub-taiga zone of the West Siberian region showed that the duration of the growing season of soybeans depended on the biological characteristics of the variety and weather conditions. SibNIIK 315 variety was characterized by the shortest growing season – 96 days, while Cheremshanka variety had the longest – 108 days. Sibiryachka and Eldorado soybean varieties were the second in terms of early ripening (102-103 days). In wet 2017 and 2018, the growing season of the studied varieties was delayed by 9-15 days compared to warm and drier 2019. The yield of soybean grain was influenced by the characteristics of the variety and weather. On average, for three years of study, the highest grain yield – 2.65 tons/ha was obtained from Sibiryachka variety. SibNIIK 315 took the second place in terms of yield. In terms of grain quality, Zolotistaya and SibNIIK 315 with protein content of 32.6 and 32.2%, respectively, were the best. The protein content of Sibiryachka variety was less – 31.5%, but higher compared to Eldorado and Cheremshanka varieties.

Abstract
The article proposes recipes for baking a bakery product with the introduction of new food additives: iodized salt, iodo-casein, amiton. The influence of iodine-containing additives on the nutritional and biological value of bread, as well as on their quality, has also been studied. It was found that the introduction of iodine-containing additives caused an increase in the volume yield of bread. So, namely, the introduction of iodized salt increased the volume yield by 12.6 %, iodo-casein caused the increase by 17.6 % and when introducing of the parameter was 12.5 % higher than the control. Bread with iodine-containing additives is a complete food product with a high nutritional value: 100 g of bread satisfy a person’s need for proteins by 8.9 %, for fat by 2.3 %, for carbohydrates by 14.4 %, and the person’s need for iodine. When daily consumption of 200-250 g of bread with iodo-casein, the iodine content will be 78-97.5 μg, or 52-65 % of the recommended physiological norm. Bakery products with iodine-containing additives are a complete food product with a high nutritional value. Therefore, to enrich bakery products with iodine, then iodo-casein, iodized salt, amiton, which contain the amount of iodine necessary for a person, can be recommended as iodine-containing additives.

Published: January 2022

Abstract
In the course of time a number of machine significant changes related to machine aging occur. The reasons for these changes are quite diverse. They are inevitable and irreversible in the time process of a gradual transition of the machine to a lower qualitative state. The article contains the data about the change in the indicators of no-failure and repairability of tractors (average restoration time) in the before-repair and between-repairs periods, which should be considered as a result of their aging. Data on the ratio of the lifetime of units and parts indicate the decisive role of the aging factor, but the lifetime can be strongly influenced by the assembly technology and the main thing - the run-in of parts. The degree of the aging of a machine can be estimated by reducing the lifetime of components, MTBF, machine productivity, etc., in the form of an aging factor, Kc. It shows how many times the lifetime of the part replaced in the machine is less than the nominal lifetime of the original part. The MTBF of the ageing machine is less than that of the new machine, or the labor input for the restoration of the old machine is greater than that of the new machine. By determining the aging rate of the parts to be replaced over the time interval under consideration, we constructed an aging function. The aging process of agricultural machinery was evaluated by the time and moment of resistance to unscrewing the uncoated threaded joints with a service life of 0.2 to 4 years. According to the obtained distribution functions, the average time increases with increasing service life, and the moment of resistance to unscrewing approaches the maximum values. With a service life of more than 4 years, the number of non-disassembled bolt connections, which break at the moment of unscrewing, increases, and the maintenance time also increases. The dynamics of the aging factors of threaded connections can be represented in the form of quadratic functions.

Abstract
Stable preservation of sown areas for agricultural production in the Russian Federation is crucial for increasing the gross grain yield. Only high-quality seeds with a low level of injury during harvesting and post-harvest processing will provide a significant increase in the yield of crops. Weediness of the grain heap decreases the yield up to 40 … 60%. According to long-term data, weediness of the grain heap in the natural and climatic regions of the CIS is 6.0 … 15.0%. Moisture during threshing is 16.0 … 20.0%, and in unfavorable years it can reach 22.0 … 25.0%. A safe storage period for such a heap is fairly limited and can attain several hours. Impurities of organic origin with the moisture content of 50.0 … 80.0% have a negative effect on the grain heap safe storage and the quality indicators of seeds. The study carried out during secondary cleaning show that the OZF-50 and OZF-80 machines provide the required productivity of 10.27 t/h and 20.40 t/h, respectively. With this productivity, the main crop content is 99.22 and 99.61%. The content of weed seeds is 3 and 5 pcs/kg, while the grinding of grain meets the technical specifications and attains 0.12 and 0.15% for the above machines. The results of regular periodic tests of the new generation OZF machines show show that all operational and technological indicators and performance indicators of the machines meet the requirements of technical specifications. The developed new fractional grain cleaners ensure the production of original seeds in accordance with GOST R52325-2005.

Abstract
Today, in agricultural land use, there is an increase in environmental problems, deterioration of environmental indicators, which negatively affect the economy of the agro-industrial complex. Elimination of negative environmental consequences often requires huge financial costs, which significantly exceed the costs of maintaining and protecting the environment, as a result of which production yield and the profitability of individual enterprises decreases, as well as the efficacy of the industry as a whole. The only way to preserve soil quality is to introduce economic mechanisms for greening land use, the most important of which is the environmental assessment of land. The aim of the research was to develop a concept for improving the efficiency and sustainability of agricultural land use based on environmental land assessment. The presented two-stage methodology for assessing the ecological state of arable land made it possible to reflect the nature and degree of manifestation of negative processes, as well as to establish the degree of anthropogenic impact on agricultural landscapes. The materials of the conducted environmental assessment served as an objective basis for the development of the concept of rational and environmentally sustainable land use within the boundaries of the municipal district and made it possible to formulate measures to improve the efficiency and sustainability of the use of arable land by agricultural enterprises.

Published: January 2022

Abstract
One of the options for improving the protein feed (the feed in the form of sunflower cake) grinders, for which Russian Federation patent No. 2648392 was obtained, is the modernization of the working surface of knife packages. They include knives in the form of an Archimedes Arbelo curvilinear triangle with saw-edged teeth along the perimeter of its entire surface of cutting edges. This will reduce the energy intensity of the process and improve the grinding quality. In literary sources, the values of the performance quantities and the energy intensity of the grinder in obtaining pelleted sunflower cake are absent. As a result of mathematical modeling of the grinding process of sunflower cake in the pelleted form, the optimal parameters of the studied factors were determined. In the indicated ranges of factors changing, the obtaining of pelleted sunflower cake is provided, it meets the zootechnical requirements for cattle with a minimum energy intensity of the grinding process E = 1.03 kWh/t and its performance W = 2.3 t/h.
