The purpose of this work is to increase the efficiency of the grain humidifier, which is part of the system for preparing grain for grinding, ensuring the reliability of machines, its productivity, reducing energy consumption and improving the quality of the finished product. products by introducing automation based on SMART technology, defined as self-monitoring and reporting technology.SMART technology is inextricably linked with a monitoring and data collection system designed to monitor and automatically manage a large number of remote, geographically dispersed sites. In addition, this system provides long-term archiving of the received data, which allows the dispatcher to monitor the operation of the relevant equipment, responding with an IT service program.A remote automated monitoring and control system for the production line on which the dampening machine is installed ensures optimum performance. Rotary machines for grain moistening are considered. At flour mills, as well as at other enterprises, such machines are used at the stage of main moistening and for additional moistening before feeding the grain to the grinding workshop. A1-BShU-2 machines are designed for basic grain moistening.Humidifiers are installed in front of the grain bins in the production lines of the preparatory departments of flour mills to remove excess moisture.At the same time, machines for washing grain and, accordingly, all equipment for treating wastewater and treated waste can be excluded from the technological schemes of enterprises, therefore, an urgent task is to increase productivity. Air humidifier A1-BShU-2 by improving the design of the working body and automation of the machine. generally.In this regard, it is necessary to intensify the process of moistening the grain due to the optimal location of the blades for moving the grain (races) and mixing (whips) on the shaft of the working body, apply a drive motor speed control system using a frequency converter.The article shows ways to improve the performance of a humidifier, as well as issues of control and management of the optimal mode of its operation. For example, Table 1 is presented in the form of a layout, which shows in what form the information can be provided to the operator and stored in the archive.

The materials of the article present analytical and scientific-practical results of research of soy multi-component functional ingredients. Soy extract (or soy milk) is a valuable and cheap source of protein and other nutritious and biologically active components, like lipids, vitamins, mineral elements, isoflavones, flavonoids, saponins etc. But the presence of indigestible oligosaccharides and a bean flavor limit the consumption of soy milk. The soy oligosaccharides are known to be prebiotic for intestinal microbiota, particularly for probiotic microorganisms that hydrolyze them with the enzyme α-galactosidase. Isoflavones are known as phytoestrogens since they are similar to human estrogen in structure and function, and are recommended to prevent many hormonedependent diseases. In soy beans and unfermented soy products, isoflavones are present mainly as biologically inactive glycoside conjugates. Biologically active aglycones of soy isoflavones are substances that are assimilated by human organism from soy products faster and in higher amounts than their corresponding glycosides. The members of intestinal microbiota are predicted to play an important role also in the metabolism and bioavailability of isoflavones since they, synthesizing β-glycosidase, cause hydrolysis of glycoside components, thus releasing the bioavailable and biologically active form of aglycone. In this work, we estimated the potential of some Lactobacillus and Bifidobacterium strains to synthesize α-galactosidase and β-glycosidase, and to reduce respectively the amount of galactooligosaccharides and to convert isoflavones into their active forms, when growing in soy milk. Simultaneously, the profile of soy milk fermentation by the chosen probiotics was studied, as well as the proteolytic activity and accumulation of lactic acid by those probiotics, i. e. the possibility to produce soy-based polyfunctional fermented food products was investigated.

The results of the study of the characteristics of the technological line for grain reception from auto transport at the procurement production grain elevator of LLC ―Agricultural Enterprise ―Vesna 21‖ are presented. In the process of research, the quantitative and qualitative composition, volumes and duration of the harvesting periods of early and late crops, the quantitative and qualitative composition and characteristics of auto transport delivering grain to the enterprise were determined; the most intensive supply of early and late crops, as well as the actual coefficients of daily irregularity of their supply by auto transport.It is shown that the enterprise in 2017-2019 traditionally received such early crops as wheat of 2-6 classes and rapeseed of the highest and 1st class. Late crops were represented by corn (3rd class and non-class) and soybeans (non-standard and extruded). The volumes of harvesting of the corn and wheat (main crops)for the indicated years correlated, respectively (%) 49.2:41.2; 60.1: 24.9 and 66.1:17.1, which indicates a tendency for a significant increase in the supply of late crops, especially corn grain. The ratio between early and late crops for 2017–2019 was 45:55, 24:76 and 20:80, respectively (%).The monthly grain flow to the grain elevator was rather irregular. Most of the grain was received from July to December, when the periods of harvesting of early and late crops coincide, and especially in the autumn months, in September, October and November, up to 32.9 %, less – in the off-season from January to June, to 12.3 %. All the same, a lot of grain in percentage terms was received in November 2017 and October 2018 – 32.9 % each.An analysis of the quantitative and qualitative composition of cars that delivered grain to the procurement and production elevator in 2017-2019 showed that the carrying capacity of the vehicles ranged from 3 ... 51 tons. In 2017, 80.9% of all grain received by the enterprise was delivered by 2771 vehicles (cars) with a carrying capacity of 20 ... 40 tons, which amounted to 82.4 % of their annual quantity. In 2018, these indicators were as follows – 87.2 % of grain was delivered by 84.5% of vehicles of the same carrying capacity, and in 2019 – 93.4 % of grain was delivered by 93.0 % of the same vehicles. In the years studied, there was a tendency to an increase in the share of more heavy-duty vehicles (35...40 t). However, the number of vehicles with a carrying capacity of more than 40 tons, delivering significant volumes of grain, has significantly decreased, which is associated with the legislative limitation of the vehicles weight. The optimal carrying capacity in terms of the ratio of the mass of the delivered grain: the number of vehicles, taking into account legal restrictions, can be recommended 35...40 tons.The main characteristics of the reception of an early and late crops at the procurement and production elevator, respectively, for 2017-2018 were the following values: the duration of the arrival of early crops, days - 126, 119 and 97, late – 142, 145 and 240; harvesting period of early crops, days – 73, 88 and 68, late crops – 86, 78 and 57; the most intensive supply of early crops, t/day – 8378, 596 and 1428, late crops 1966, 1576 and 1909; actual coefficients of grain reception irregularity by auto transport of early crops – 6.3; 2.2 and 3.6, late – 2.5, 2.4 and 2.9, which exceeds the standard values of 1.6 and should be taken into account when improving the operation of the grain reception line.

The following article presents a new raw component in compound feed for carp – feed concentrate produced from cereal production waste. The feed concentrate is based on several types of cereal fodder meal - wheat, pea, barley, as well as wheat bran and unshelled oat grain. The feed concentrate is balanced according to the needs of carp and can be used as feed for carp instead of wheat grain or as a part of compound feed for carp. Heat-moisture processing of compound feed before extrusion is one of the main stages that further ensure the stability of technological processes and the final quality of the feed concentrate. The amino acid composition was determined at various temperatures of the feed concentrate after heat-moisture treatment of + 40, 60, 70 and 80º С at a constant moisture content of the concentrate of +282° С. Amino acid score has been calculated for feed concentrates that have been exposed to various heat treatments. The amino score was calculated in relation to the carp's need for essential amino acids. It was found that an increase in the temperature of the concentrate during heat-moisture treatment leads to a decrease in the content of essential amino acids. For example, the total content of methionine and cysteine in the composition of the feed concentrate at a temperature of +75° C was 0.46%, with the minimum allowable total content of these amino acids in the composition of feed 0,5%. Heat-moisture treatment at a product temperature above +75° C leads to a decrease in the content of essential amino acids and the biological value of the feed concentrate.The process of extrusion of feed concentrate from waste of cereal production has been studied. The glucose content in the feed concentrate was studied at various extrusion modes. The glucose content indicates the degree of modification of the starch during the extrusion process, and the more glucose the product contains, the better it is absorbed by the carp. When extruded with an increase in temperature, the starch passes into a viscous-flowing (gelatinized) state, forming a so-called melt, the cooling of which also leads to the formation of a three-dimensional gel network. The feed concentrate granule becomes monolithic in structure; it becomes quite hard and can harm the intestines of carp. Therefore, it contains wheat bran in an amount of 1%, as a component that is able to weaken the feed concentrate granule. The degree of starch destruction in the composition of the extruded feed concentrate with the addition of wheat bran reached its maximum and the granule became porous, its hardness decreased. It was detected that when the temperature of the feed concentrate after extrusion rises above +100°C, the biological value of the feed concentrate decreases, and it becomes unbalanced in the content of such essential amino acids as lysine, threonine, methionine and cysteine. Therefore, the optimum product temperature after extrusion is +90-100˚C.The effectiveness of extruded feed concentrate was determined in the composition of granulated feed for two- and threeyear-old carp. The feed ratio of the compound feed containing the feed concentrate was 0.9 units, which is 64% lower than of the control compound feed, which includes a non-extruded grain group that is not balanced in terms of carp needs.

Washing machines are used in the production lines of grain cleaning departments of flour mills for thorough cleaning of the grain surface, in particular, its grooves from the remnants of organic and mineral dust, microorganisms and mold. In addition, the grain mass during washing is cleaned of hydrodynamically light and heavy impurities - chaff, seeds of waste plants, straw fragments, mineral particles in the form of sand, small stones, lumps of earth, as well as spores and wormwood seeds. At the same time, foreign odors of grain disappear.Experience in the operation of Ж9-БМА machines shows that along with many advantages, they have some disadvantages. In particular, the productivity of the machine 10 t / h does not correspond to the productivity of the conjugated technological equipment of the production line, and the specific water consumption for washing grain is 1.8… 2.0 l / kg, which is too much in modern conditions of acute shortage of drinking water. Enterprises to abandon the use of washing machines. In addition, certain problems and inconveniences are caused by the design of the sieve shell of the impression column. Stamped sieves with scaly asymmetric holes have a low coefficient of living cross section, which complicates the process of dehydration of washed grain, quickly corrode and rub, require special attention during installation or replacement. Therefore, an attempt is made to eliminate these shortcomings.In particular, the reduction of water consumption is achieved due to the elimination of the grain hydraulic conveyor during its transfer from the washing bath to the pressure column. For this purpose, a device for mechanical overloading of grain by a rotary bucket device located within the alloy chamber is used. At the same time, attention was paid to the separation of light organic impurities from the grain. This decision needs further explanation.The functional diagram shows that the initial grain mixture enters the receiving device, which feeds it with a minimum vertical speed into the ascending water streams created by the screws of two grain augers rotating with the same frequency in the opposite direction. The augers pick up the grain and, keeping it afloat in a suspended state, mix it with the water of the washing bath. At the same time the grain is washed and particles are separated from it, which differ from it in terms of density: mineral impurities begin to sink, fall down and through the longitudinal slit in the auger trough fall into the area of the auger for mineral impurities. This auger transports the "stones" in the opposite direction to the funnel with the ejector of the hydrotransporter of mineral particles. Light impurities, during the transportation of grain by grain augers, float to the surface of the water, the level of which in the washing bath is maintained up to the axis of the augers. Together with grain and water, these impurities are pushed out of the bath into the alloy chamber.In the chamber, in the transverse direction, a pipe with a longitudinal absorption slot is installed, the lower edge of which is immersed in water so that the upper layer of water merges into this slot together with light impurities that have surfaced in the washing bath. The amount of water that fuses light impurities can be adjusted by the depth of immersion in water of the lower edge of the absorption hole. To do this, the pipe is rotated relative to its axis with a special handle with a clamp and a pointing scale. One end of the pipe is closed by a plug, and the other passes through a hole in the wall and drains the water with light impurities into the sink sump. The described device provides almost complete removal of light impurities and minimal consumption of floating water. This solution is in the invention according to the copyright certificate 701708404, developed by specialists of the department TOZV. In addition, certain problems and inconveniences are caused by the design of the sieve shell of the squeezing column. Dirt particles tend to stick to the outer surface of the sieve cylinder and block its holes. This can slow down and even stop the separation of water by centrifugation. Therefore, the upper outer surface of the cylinder is washed with water, which in automatic mode is periodically fed to the sieve by the control device and the solenoid valve. It also saves water.

High productivity and power of technological and transport mechanisms, large capacity and number of storage equipment, a variety of types of grain crops simultaneously processed at the elevator require the operator to make a lightning-fast decision, the optimal choice of grain transportation routes.One of the first control systems consisted of huge energy-intensive cabinets with starting equipment, allowing remote control of equipment, without the functions of elementary control of their operation.As storage volumes increased, these systems were supplemented with relay cabinets, whose task was to conduct interlocked control of an ever-increasing number of mechanisms, so that at least somehow it was possible to control such a complex. These relay cabinets had a low degree of reliability (contact elements), consumed a large amount of energy, and required the constant presence of large maintenance personnel.The era of microelectronics has come, which completely changed the idea of the capabilities of control systems. At first, it seemed very expensive and not a quick payback. But every year, the cost of automation equipment is decreasing, reliability has grown to high levels and this technique has come to the management systems of grain storages and elevators.Modern automation at the majority of Ukrainian elevators makes it possible to control technological processes. At the same time, many processes are regulated in a mode that requires a sufficiently high qualification of service personnel. The exchange of data on the operation of SMART-INDIVIDUAL equipment is carried out by logical controllers by polling sensors, generating control actions, monitoring equipment operating modes with display in the WEB-interface system. The SMART-INDIVIDUAL system has undeniable advantages over existing centralized control and management systems. SMART technology is inextricably linked with the dispatch control and data collection system - SCADA, designed to monitor and supervise a large number of remote objects or one geographically distributed object. The SMART-INDIVIDUAL system is equipped with a module with a regulation for monitoring parameters, equipment according to the passport characteristics. At the same time, the system maintains an archive and controls the timing of maintenance. The laboratory installation SMART-INDIVIDUAL includes technological and transport equipment, which is most used in the elevator industry: air filter ZEO-FCS, bucket elevator ZEO-BE, scraper chain conveyor ZEO-DC. On the basis of the SMART-INDIVIDUAL software and hardware complex at the Department of Technological Equipment for Grain Production of the Odessa National Academy of Food Technologies, students are trained in the new specialty "IT service of equipment".

The work is devoted to determining the physical and technological properties of quinoa grain. Quinoa is an unconventional crop for Ukraine, but experiments on its cultivation have been successfully completed in the Sumy region. Due to its unique chemical composition, quinoa is used in dietary and functional products.Quinoa contains about 20% protein, which makes it an excellent dietary supplement for people who do not eat animal products. The amino acid composition of quinoa proteins is very balanced and is characterized by a high content of such essential amino acids. Feature of the fatty acid composition of quinoa. it has a high content of polyunsaturated fatty acids, including linolenic fatty acid and linoleic, which belongs to the acids ω-3 and ω-6 fatty acids.Due to the growing popularity of quinoa and its suitability for cultivation in our climatic and soil conditions, it is important to develop the technology of its storage and processing. One of the main stages of substantiation of the choice of technology for storage and processing of quinoa grain is to determine its physical and technological properties.Physical and technological properties of grain mass are determined by a large number of indicators.Determination of physical and technological properties of quinoa grain was performed for three types of quinoa: red, black and white. In determining the physical and mechanical properties were used methods approved by the relevant standards, or used in research and recommended in the relevant literature.We have identified the following basic physical and technological properties: geometric characteristics, nature, weight of 1000 grains, duty cycle, packing density, air supply, angle of natural slope, coefficient of internal friction, coefficient of external friction. Numerical values of these indicators for each type of quinoa are determined.Knowledge of the physical and technological properties of the grain mass to solve a large number of applied problems that have practical significance. and play an important role in the processes of moistening, heating and cooling of grain. A thorough study of physical and technological properties can provide optimal conditions for storage of seeds without compromising their quality. The obtained data can be used for selection of modes of cleaning, drying and active ventilation.

This article mainly introduces the necessity of the emergence of functional foods and the current market development. Using chia seeds as the characteristic raw material, adding apple juice and hawthorn juice, it is developed to be suitable for subhealthy people, obese people, diabetes and cardiovascular patients.Functional beverages refer to beverages that regulate human body functions to a certain extent by adjusting the composition and content ratio of nutrients in the beverage. In recent research hotspots, chia seeds are often developed and applied by nutritionists or other nutrition enthusiasts because of their rich nutritional value. Chia seeds are rich in a variety of unsaturated fatty acids, accounting for about 80% of the total fatty acid content, of which omega-3 and omega-6 unsaturated fatty acids are the most content, 68% is α-linolenic acid, which is the most abundant omega-3 fatty acid content of the food. Each 100g of chia seeds contains about 16-25g of protein and about 26-40g of dietary fiber, including all 8 amino acids needed by the human body. In addition, it is also rich in vitamins and minerals, as well as a variety of natural antioxidant ingredients, with high-quality antioxidant functions. This makes the ability of chia seeds to maintain blood sugar stability, protect the heart, cerebrovascular, and promote gastrointestinal motility and bone health cannot be underestimated.Hawthorn contains a large amount of vitamin C, carotene, organic acids and other nutrients, combined with cellulose, pectin and organic acids in apples, can further assist chia seeds to improve gastrointestinal conditions and promote gastrointestinal motility, while soluble fiber Vegetarian can regulate blood sugar.This article chooses apple and hawthorn as flavor bases, oligosaccharides (FOS) as sweeteners, resistant starch and guar gum as composite stabilizers, to produce a chia seed functional drink to reduce weight and improve heart and brain Vascular health problems. In the extremely poor analysis of the orthogonal test results of the chia seed functional drink, the best sample formula.
