According to the requirements for the technological processes of purification and separation of the seed mixture to obtain the sunflower seed material of the parent components (varietal purity – 98,0-99,9%) for all parts of the breeding and seed production process, a rational precision technological scheme of the separation processes has been developed, which includes automation of technical processes of separation means. In order to increase the efficiency of the sunflower breeding and seed-growing process, a device for automatic seed phenotyping has been added to the developed technological line, which can significantly intensify and shorten the breeding process and improve the design of the breeding program through bioinformatic data analysis and seed sorting. Functional dependencies are established and methods of automated control of precision mechanized process of seed separation are developed on the basis of coordination of its mode and technological parameters. Tape device for automatic phenotyping of sunflower seed material according to its morphological and marker features have been developed. The device are configured for high accuracy of individual measurement of the geometric dimensions of sunflower seeds with determination of their shape and color and provide low complexity and high technological implementation of the phenotyping process (determination, identification and separation) of seeds.

AbstractThe development of automated precision technologies for the phenotyping test of seeds by a complex of functional features in the selection process of sunflower is relevant and promising. The task of developing a device for the automatic phenotyping test of seeds and the algorithm for finding and isolating seeds based on color information was set. Research was conducted on a stand, which consisted of the following elements: Video Microscope Camera 1080 P 16MP HDMI USB manufactured by Eakins, a set of LEDs of three types (red, green, blue) and a personal computer.The results of experimental studies of the process of automatic phenotyping test of seeds of different sunflower varieties allowed us to establish an average error of determining the geometric dimensions of sunflower seeds (length L and width B) – 0.06 mm. The histograms of the color distribution of sunflower seeds in the RGB color space with different illumination are established. As a result of the analysis of the obtained histograms of the color distribution of sunflower seeds in the RGB color space it is established that in the case of color homogeneity, the discreteness of the channels with red illumination is most clearly seen.A device for automatic phenotyping test of seeds has been developed, which preserves the accuracy of individual measurement of the geometric dimensions of sunflower seeds, determining their shape and color, which corresponds to modern measuring tools, and provides low complexity and high technological implementation of the phenotyping test procedure (determination, ascertaining and identification) material, according to its morphological and marker features.

To solve a number of technological issues, it is advisable to use mathematical modeling, which will allow us to obtain the dependences of the influence of the technological parameters of chemical and thermal treatment processes on forming the depth of the diffusion layers of steels and alloys. The paper presents mathematical modeling of diffusion processes based on the existing chemical and thermal treatment of steel parts. Mathematical modeling is considered on the example of 38Cr2MoAl steel after gas nitriding. The gas nitriding technology was carried out at different temperatures for a duration of 20, 50, and 80 h in the SSHAM-12.12/7 electric furnace. When modeling the diffusion processes of surface hardening of parts in general, providing a specifically given distribution of nitrogen concentration over the diffusion layer’s depth from the product’s surface was solved. The model of the diffusion stage is used under the following assumptions: The diffusion coefficient of the saturating element primarily depends on temperature changes; the metal surface is instantly saturated to equilibrium concentrations with the saturating atmosphere; the surface layer and the entire product are heated unevenly, that is, the product temperature is a function of time and coordinates. Having satisfied the limit, initial, and boundary conditions, the temperature distribution equations over the diffusion layer’s depth were obtained. The final determination of the temperature was solved by an iterative method. Mathematical modeling allowed us to get functional dependencies for calculating the temperature distribution over the depth of the layer and studying the influence of various factors on the body’s temperature state of the body.

Разработаны технология и установка для переработки отработанных фильтровальных порошков (ОФП) в кормовые продукты (КП) на масложировых предприятиях после вымораживания подсолнечных масел с целью исключения процесса их окисления. Предложена модернизация ранее разработанной авторами технологии переработки отходов очистки семян подсолнечника (ООСП). Рекомендовано добавление во вторичное масличное сырье (ВМС) из ООСП обезжиренных центрифугированием ОФП. Установлено, что центрифугирование необходимо осуществлять в течение 35 мин при 900 об/мин центрифуги. Определена наибольшая эффективность прессования с экструдированием при добавлении 1–3% обезжиренного фильтровального порошка в ВМС. Установлено максимальное количество обезжиренного фильтровального порошка (10%). Совместная переработка ООСП и ОФП на созданной экспериментальной производственной установке позволила получить КП в соответствии с требованиями нормативных документов на подсолнечный жмых и КП «Подсолнечный» для сельскохозяйственных животных. It has been suggested modernizing the previous technology for recycling of sunflower seed waste, developed by the authors that included waste separation to obtain secondary oily raw materials. A technology and installation has been developed for recycling spent filter powders into fodder products immediately after freezing of sunflower oils at oil and fat plants to exclude the process of their oxidation. It is established that the centrifugation must be carried out for 35 min at 900 rpm of the centrifuge. The greatest efficiency of pressing with extrusion is determined when adding 1–3% of fat-free filter powder to secondary oilseeds. The maximum amount of fat-free filter powder (10%) is set. The co-processing of sunflower seeds waste and spent filter powders at the created experimental operation-performing installation made it possible to produce an experimental fodder product which meets the requirements of normative acts for sunflower seed cake and sunflower fodder product «Podsolnechnyy» used for feeding farm animals.

Growing sunflower (Heliianthus annuus L) for consumption is becoming more and more attractive in the whole world and in our country, as well. The consumption of this product has been considerably increased because it is being used more and more in various forms: sunflower seed in a hull, hulled kernels fried or non-fried, salted or non-salted with addition of various spices. The sunflower kernel is used for preparing over 100 different food products: special types of bread, cakes, ice-cream, chocolate. In accordance with the trade demands, the aims of sunflower seeds for consumption improvement are: high productivity, greater content of proteins, lesser content of oil, oncreased mass of 1000 seeds, lesser portion of the hull easy nibbling, as well as tolerance to dominant diseases in the growing region. In the Agricultural and Technological Research Center in Zajecar, 4 genotypes of protein sunflower (two cultivars and two hybrids) have been created so far. This study shows the results achieved in increasing the content of protein, the mass of 1000 seeds, decreasing the content of oil and hull of the new 90 hybrid combination. The hybrid combinations were obtained by crossing of the CMS and restorer lines.

The study examined the effects of two methods of processing de-hulled sunflower seed meal (SFM) from the same batch of sunflower seeds. Sunflower seed meal was fed to broilers as meal (MSFM) or after it had been pelleted (PSFM) at 75 °C and 360 kPa pressure to pass through a 3 mm mesh. Three diets were prepared, namely a balancer feed (BF) and two diets containing 200 g/kg MSFM or 200 g/kg PSFM. They were fed to 30 pens (two birds each) with male Ross 308 broilers, from 8 to 21 days old, following randomization. Data were analysed by ANOVA. Two pre-planned orthogonal contrast tests were performed to compare overall differences between the diets containing SFM and BF and between diets containing the MSFM and PSFM. The BF had a very different nutrient composition from the complete feeds containing SFM so, as expected, there were differences in growth performance and nutrient retention. The diet containing PSFM had greater apparent metabolizable energy corrected for N retention (AMEn) and dry matter retention (DMR) than that containing MSFM. The use of the substitution method showed the PSFM had AMEn that was 18% greater than the MSFM (8.79 vs 7.47 MJ/kg DM). Under the conditions of the current study, incorporating PSFM in a mash broiler feed increased dietary AMEn compared with the same feed containing MSFM. Further studies are needed to identify whether the benefits of pre-pelleting SFM remain after this product has been incorporated in complete pelleted broiler feeds.

Fats as complex mixtures of acylglycerols with lipid and non-lipid substances are an integral part of human nutrition. The presence of acylglycerols of trans-isomers of fatty acids causes many cardiovascular diseases and metabolic disorders. A promising approach to solving the problem of minimizing the content of these undesirable compounds in food recipes is to create a new generation of fat systems, oleogels, which are the subject of this study. High-oleic sunflower oil was used as a dispersion medium of oleogels, which allows obtaining systems with increased resistance to oxidation, as opposed to the oils of traditional kinds. Sunflower seed wax and tocopherols are chosen as a dispersed phase of these fatty systems. The choice of these components was based on their properties to create a three-dimensional structure in oleogels with specified thermomechanical characteristics. Currently, there is a lack of information on the influence of the content of the dispersed phase on the technological parameters of oleogels, namely oxidative resistance and sorption properties. The purpose of the presented work was to study these features of oleogels and establish their dependences on their composition. To solve this problem, the yield surface method is used in the work. The unknown values of the parameter vector were determined by using regression analysis algorithms. Deviation functionality was minimized by finding the appropriate combinations of the experimental series of predictors. A mathematical model was developed which allows predicting oxidative stability and sorption properties of oleogels based on the data on their composition. The suitable mass fractions of the components of the dispersed phase of oleogels have been determined as follows: tocopherol content is 0.10–0.14 wt.% and the sunflower seed wax content is 1.8–4.0 wt.%. The results obtained can serve as a scientific basis for the development of technology for the industrial production of oleogels as new generation fatty systems.

Для утилизации отработанных отбельных глин (ООГ) масложировой промышленности предложено получение комбинированного кормового продукта (ККП) непосредственно на масложировых предприятиях, при переработке ООГ совместно с отходами очистки семян подсолнечника (ООСП). Обоснованы рецептуры и технологии ККП на разработанной нами ранее производственной линии, включающей обогащение ООСП сепарированием, экструдирование и прессование полученного вторичного масличного сырья. На линии был смонтирован дополнительный узел, обеспечивающий равномерное распределение строго определенного количества ООГ во вторичном масличном сырье из ООСП. Исследовано влияние количества внесенных во вторичное масличное сырье ООГ на процесс отжима масла. Обосновано, что для производства ККП во вторичное масличное сырье необходимо добавлять не более 2 ООГ. Полученный ККП по показателям безопасности соответствует белковолипидному кормовому продукту Подсолнечный (ТУ 914637502067862 2014): массовая доля, , в пересчете на абсолютно сухое вещество сырого протеина составила 27,8 сырой клетчатки 30,6 общей золы 7,6. Установлено незначительное увеличение в ККП массовых долей сырого жира и золы, не растворимой в соляной кислоте 15,8 и 1,4 соответственно. Полученное масло по жирнокислотному составу и показателям качества не отличается от масла из ООСП. For the disposal of spent bleaching clays (SBC), we proposed to obtain a combined feed product from them directly at oil and fat enterprises, processing together with the sunflower seed cleaning waste. The formulation and technology for the production of the combined feed product were developed on a previously tested production line, including the enrichment of waste products for cleaning sunflower seeds by separation, extrusion and pressing of the obtained secondary oilseeds, for which a unit was added to ensure uniform distribution of strictly measured amounts of SBC in it. Conducted by studies on the effect of the amount of waste bleaching clay added to secondary oilseeds from waste products from cleaning sunflower seeds on the oil extraction process, it was substantiated that for the production of a combined feed product, no more than 2 of SBC should be added to secondary oilseeds. The resulting combined feed product in terms of safety corresponds to the Proteinlipid feed product Sunflower, produced under 914637502067862 2014 specification, while the combined feed product is slightly higher than the mass fraction of crude fat and ash insoluble in hydrochloric acid. The obtained oil on fatty acid composition and quality indicators practically does not differ from the oil from sunflower seed cleaning waste.

The scientific article presents a physical model of the technical process of co-extrusion processing of secondary polymeric materials. A set of tools for automated control and monitoring of the model is considered, which allows to adjust smoothly the values of the rotational speeds of screws of extruders, the temperatures in the material heating zones and the pressure at the outlet of the co-extrusion head. The results of experiments to determine the temperature of the parison over a cooling time and the effect of screw speed and pressure in the head on the quality of mixing components are given. The results obtained by physical modeling confirm the correctness of the authors' calculations performed using the proposed mathematical models. Thus, it is possible to continue research in this direction, the result of which will be new designs of co-extrusion equipment, allowing to process efficiently polymeric waste into new high-quality products.

This study determined production performance, nutrient digestibility, and milk composition of dairy ewes supplemented with crushed sunflower seeds (Helianthus annuus) and sunflower seed silage in corn silage-based diets. Six ewes were grouped in a double 3 × 3 Latin square design with three periods of 21 days. All treatments were based on ad libitum corn silage. Control diet was based on alfalfa hay (333 g/kg DM), sorghum grain (253 g/kg DM), triticale grain (200 g/kg DM), soybean meal (167 g /kg DM), and vitamin and mineral premix (47 g/kg DM). Sunflower seeds (SF) and sunflower seed silage (SFS) treatments consisted of alfalfa hay (333 g/kg DM), sorghum grain (267 g/kg DM), triticale grain (100 g/kg DM), soybean meal (167 g /kg DM), SF or SFS (87 g/kg DM) and vitamin and mineral premix (47 g/kg DM). Compared to control, SF and SFS increased intake and digestibility of fiber components, such as neutral detergent fiber (NDF) and acid detergent fiber (ADF). Body weight, nitrogen balance, milk yield, milk fat yield, milk protein yield, lactose yield and milk urea N were similar between treatments. Overall, results demonstrated that crushed sunflower seeds and ensiled seeds do not change significantly productive parameters of dairy sheep.
