Abstract
Summary. Development of food technology in the last two decades, faced with a new negative phenomenon. The fact that this period - the time of stagnation of domestic production of food, the mass of imports and import equipment for the agricultural, processing and food technology. This significantly reduces the food security of Russia. One reason for this state of food production has methodological crisis in science and engineering, agribusiness country. The dialectical method considers the category of "system" in all its aspects, so a systematic approach to problem solving AIC Russia - this is not a fad, but the need for such an approach to the creation of technological systems. The effect of the same prize, arises in the construction of the highest forms of technological systems. Systematic approach should reveal the cause of the large systems, and the largest of their shape - complexes show the historical inevitability of their formation, dialectical process of development of these young but highly efficient units. We need to understand and realize that the system technological systems in agriculture - one of the most important factors of progress in the science of the production and processing of agricultural products. System process systems have completely new properties are not typical for either production technology of plant and animal products, nor for many of its processing technology. Thus, the complex is created for significant efficiency gains in food production. The purpose of the article - to reveal and analyze the effect of a complex system arising under the influence of various system factors, when combined into a single unit producing and processing agricultural technologies Russia.

Summary. The task of exergy analysis - evaluation based on the second law of thermodynamics, thermodynamic degree of technical perfection of the whole system, as well as to identify those stages of a technical process, which contains the bulk of the loss of exergy in order to improve its efficiency. Using exergy analysis allows to solve a wide range of technical problems on the basis of a unified thermodynamic methods. Exergy analysis was performed by the method whereby thermotechnological system candied fruit production, conventionally separated from the environment of the closed control surface. Exchange scheme under consideration thermotechnological candied fruit production material, thermal and energy flows to the environment, as well as between the control surfaces. Exergy in external input material streams: air and water and citric acid, as well as output streams without having increment Shih-exergy in the process of passing through the reference surface - of running air-water and after washing, are in thermodynamic equilibrium with the surroundings is zero. In the total number of internal exergy losses include losses from the final result of the temperature difference in the heat exchange between the raw material to be dried and heated air electromechanical arising from irreversible alteration of structural and mechanical properties of the product, and the hydraulic loss due to the sudden increase of the specific volume of air as it enters the working chamber dryer. The resulting exergy efficiency is 8.87 %, which is 3.7 % higher than when using the technology of the prototype based on solar air-dried product. This indicates an increase in the degree of perfection of the thermodynamic system by using microwave heating of the product in combination with the removal of moisture in the atmosphere low temperature coolant, which precludes significant outside exergy loss on drying step.

Abstract
Summary. The urgency of theme is substantiated and the basic directions of studies are determined. Is substantiated the mechanism of the process of the concentration of liquid media by freezing moisture, that is determined in essence by the conditions for the migration of the molecules of water to the frontal surface of crystallization and their incorporation into the crystal structure of ice. It is shown that the regime of freezing moisture is characterized by the temperature of the heat exchange surface, which receives heat of crystallization of moisture, by the speeds of displacement and with the surface area of the contact of the being transferred heat media, by form and by the concentration of the dissolved substances of product. The process of heat exchange between the surface of crystallization and the workable technological medium is described. The schematic of the work of the experimental freezing out installation and the procedure of experiences is represented. Are investigated a change in the average value of a quantity of frozen out ice from the unit of heat exchange surface, which freezes out installations in the time, reflected in the form of the curves of increase and rate of growth in the icy phase on the surface of the heat exchange elements of area of 0.08 m2 , in 3600 seconds depending on the temperature of the heat exchange surface and initial content of dry matter in the cherry juice. An increase in the initial content of dry matter in the cherry juice at constant temperature of boiling refrigerant in the vaporizer of the freezing out installation nonlinearly reduces the specific quantity of ice, which was being formed on the heat exchange surface. A change in the boiling point of refrigerant also causes a nonlinear increase in the specific quantity of ice, frozen out on the heat exchange surface. The obtained curves of the rate of growth in the icy phase make it possible to isolate the sections of the crystallization of the moisture, which has different nature of connection with the solute. Is investigated a change in the degree of concentration of cherry juice with the freezing from the boiling point of refrigerant and initial content of dry matter. It is shown that the degree of the concentration of cherry juice is reduced with an increase in the initial content of dry matter in it and an increase in the boiling point of refrigerant in the vaporizer of the freezing out installation.

Summary. The mathematical model of kinematics of a plastic shaping at the sinking of a thin-walled precision pipe applied to calibration of the ends of the unified elements of the pipeline of aircraft from titanic alloys and corrosion-resistant steel before assembly to the route by means of automatic argon-arc welding of ring joints is developed. For modeling, the power criterion of stability with use of kinematic possible fields of speeds is applied to receiving the top assessment of effort of deformation. The developed model of kinematics of a plastic current allows to receive power parameters of the main condition of process of calibration by sinking and can be used for the solution of a task on stability of process of deformation by results of comparison of power (power) parameters for the main (steady) and indignant states. Modeling is made in cylindrical system of coordinates by comparison of options of kinematic possible fields of the speeds of a current meeting a condition of incompressibility and kinematic regional conditions. The result of the modeling was selected discontinuous field of high-speed, in which the decrease outer radius (R) occurs only by increasing the thickness of the pipe wall (t). For this option the size of pressure of sinking had the smallest value, therefore the chosen field of speeds closely to the valid. It is established that with increase in a step of giving 1 at calibration by the multisector tool the demanded pressure of sinking of q decreases. At an identical step of giving 1 pipe with the smaller relative thickness of (t/r) needs to be calibrated the smaller pressure of sinking. With increase of a limit of fluidity at shift of material of pipe preparation pressure of sinking of (q) increases.

Abstract
Summary. In the polymerization of butadiene with styrene heat removal is the main factor limiting the output of the cascade reactor. Thus the residence time of the monomers in the reactor exceeds significantly the time necessary to complete the process on the basis of kinetic regularities. To increase the output of the mixture the distribution in the reactor cascade is made. It is necessary to distribute the flow of mixture through the reactor of the cascade to have the resulting polymer of the same viscosity at the outlet of each reactor. The algorithm of distribution of the mixture in the reactor cascade with regard to the synthesis parameters (temperature in the reactor and the feed rate of the mixture, the ratio of the modifier and the initiator in the complex), the number of reactors and a determined dynamic viscosity is developed. In accordance with the developed algorithm the calculation of the velocity of the mixture feed in each reactor of the cascade is made. It is shown that the flow of mixture in each polymerization unit depends on the overall output of the installation and the number of reactors in the cascade. The algorithm for the distribution of the initial mixture in the reactor cascade is developed to provide maximum output of the installation and set the quality of the obtained polymer. To determine the degree of conversion of monomers and temperature conditions of the process of polymerization under the calculated speed of the feed mixture in the first polymerization cascade the basic technological parameters of the polymerization process in real time mode, the calculation using a mathematical model is made. The analysis of the simulation results shows that during the first hour, the concentration of monomers does not exceed of 0.085 mol/l, which corresponds to the degree of conversion of monomer to 99 %, while the temperature in the reactor corresponds to the optimal mode - from 65 to 85 0C.

Summary. Existing theoretical calculations speeds in areas of horizontal and vertical curves designed for the needs of construction and calculation of cars and can not be used for valuation. When calculating the value of the coefficient of friction velocity determined at full wheel lock that does not correspond to the actual conditions of braking stability conditions of the car within its lane. The article proposes to calculate the permissible vehicle speed for the sites of horizontal and vertical curves on forest roads from the requirement car stop within the zone of visibility without buckling considering assumptions: during braking movement remains manageable, the driver keeps the car in the outside lane; magnitude of the angular velocity of the steering wheel is small; fully utilized inhibitory properties least loaded wheel; cornering power coefficient of resistance of tires depends little on the change of loads on the bus; low rolling resistance. Studied are normal reactions to the vehicle wheels when braking, namely found that if the friction coefficient on the road for less than the calculated optimal braking, the restriction on the braking occurs danger of losing control of the car skidding due to the front wheels. If the coefficient of friction on the road more than the calculated optimal braking, the braking force limitation occurs for blocking the rear axle. When comparing full stopping distance with the existing area of visibility is determined permissible speed.

Abstract
Summary. The technological process of thermal oxidative degradation on the basis of initiator fractional loading is considered. The advantage of controlled degradation at the initiator fractional loading in order to provide continuous dosing of the initiator with high accuracy is difficult in industrial environments. Slight deviations caused by dispensers error, can significantly change the kinetics of degradation, due to high sensitivity of the initiator concentration. From the point of view of the technology realization the process of fractional dosing initiator is more convenient. It is shown that carrying out the controlled degradation under identical initial conditions reaction, we manage to reduce significantly the time of the process to the desired degree of degradation. The reaction time is reduced to more than 1.5 times. Carrying out a controlled degradation allows implement the projected degradation by linear law depending on time. Kinetics linearity is provided at a continuous loading of initiator and as well as a fraction loading. In this case the fractional loading should be done at regular intervals of time. The reaction time is control parameter in both control regimes which is linearly connected with to the given degree of degradation. In this case, the opportunity to control software arises, herewith we need know only the initial quality of the polymer, i.e. its initial number average molecular weight. The calculated dependences, which allow estimate a single loading initiator value, depending on the period of the fractional dosages of initiator are obtained. An approximate calculation linear dependence of the degradation process kinetics in the case of initiator continuous loading and under fractional loading are shown.

Summary. Realization of metrological testing information-measuring complex road laboratories to automate the geometry of the road requires the development of theoretical foundations and methods of their implementation. As the main research method adopted the method of comparing the accuracy of the results obtained with it, with similar results obtained based on survey. In this survey data taken in the main, because they have the highest accuracy. An algorithm for statistical processing of measurement results areas of forest roads using test-measuring system. The paper presents an algorithm for determining the geometric variables on the example of two roads: the angle of rotation, the length of the curve. The authors have developed a formula that allows to assess the accuracy of measurement of the angles of rotation axis of the road on the road with the help of rounded to reflect changes in laboratory error depending on averaging the results (number of shuttle drives ) and to determine the optimal number of driveways. Also in the article formula is proposed to evaluate the accuracy of determining the length of the curve curvature using road laboratory. Error in measuring the length of a curve is proposed to determine the position errors start and end points of curvature. When traveling laboratory "round-trip " by rounding can obtain an average length of a curve to be more precise definition of this unit of length for each passage. The method developed can be applied to determine all the remaining geometric variables of the road.

Summary. In constant aspiration to decrease in expenses in the course of production of meat of broilers many processes are automated, and quality of many of the Russian overworking enterprises doesn't concede to the international standards any more. However the domestic enterprises sustain still considerable losses on decrease in categorization and deterioration of carcasses of the broilers which are handed over on slaughter. Quality of fowl depends on a number of factors. Process of devocalization has the defining impact on qualitative characteristics of finished goods. A number of factors which prove use of a gas way of devocalization is revealed (higher level of an bloodless allows to improve quality of meat, the gas which is applied in system of devocalization lulls a bird and allows to give a bird to the line of an unconscious hinge plate). Use of a gas way allows to get rid in many respects of problems inherent in an electric method of devocalization of a bird: electric discharges before devocalization, unevenness of categories, restoration of activity of a bird after devocalization, traumatism; unevenness of bloodless, difficult working conditions of operators of a hinge plate (dust, noise and other), need of fixing of a live bird, different quality of devocalization of different weight bird. In article data on studying of influence of devocalization of a bird are provided in the controlled gas environment on indicators of quality of meat of broilers. Comparison of ways of devocalization is carried out: gas and electric. Consistent patterns of change of pH in fowl depending on a way of devocalization are determined. On the basis of the obtained research data it is possible to draw a conclusion on expediency of use of a method of gas devocalization at slaughter and primary processing of broilers that will allow to increase competitiveness of domestic poultry farming significantly.

Summary. The knowledge of regularities of deformation behavior of the processed confectionery masses with certain rheological properties allows to calculate parameters of shaping process and to select processing equipment for its carrying out. The article studies the obtaining of the rheological equation of deformation behavior of sugar dough in the conditions of monoaxial compression which is realized in sugar cookies dough pieces formation processes. The results of the pilot studies confirming adequacy of the offered rheological equation are presented. The behavior of an elastic-, viscous- and plastic body in the conditions of quasistatic test for creeping during which the set size is tension, and the measured one is relative deformation is considered. The main rheological properties of sugar dough received experimentally are given. Values of rheological constants are received and it is revealed that at 95% confidential probability, the rheological equation for the general deformation of an elastic-, viscous- and plastic body adequately describes experimental data. The maximum fault thus makes 2,3%. It is established that dough pieces shaping processes from the sugar dough possessing visco- and plastic properties should be realized at an external tension (power impact from the forming body) which exceeds a limit of fluidity of the dough formed. The level of external tension, as well as the duration of its influence (that is formation duration) should be chosen taking into account the residual deformations in the processed mass which guarantee giving of a certain geometrical form and drawing on a surface of dough pieces. The rheological model of sugar dough allows to predict its deformation behavior in the formation conditions, and to calculate the parameters of sugar dough formation process.

Abstract
Summary. Modern ecological state of the environment and human unhealthy diet cause many diseases. A healthy diet is the one that contains adequate amounts of proteins, fats, carbohydrates, vitamins, macronutrients and micronutrients. Photosynthesis i. e. the process by which plants produce organic compounds from carbon dioxide and water, is the source of life, the source of evolution and proliferation of life forms on the Earth. Thus, the juice made from sprouted barley provides physiologically active chlorophyll, macronutrients and micronutrients, vitamins А, В2 , В3 , В5 , В6 , В8 , Е and К. It is well known that light from a red laser with a wavelength of 638.2 nm has a stimulating action on the germination energy, germination ability and productivity of seeds, and on the crop yields. Therefore, this research is of primary importance today. The research result produced a sharp decline in plant vigor and germinating capacity of barley when soaking in 1n sodium carbonate solution, as well as changes in the ratio of potassium-sodium balance in plants. Thus at lower concentrations of sodium carbonate and 0.1 n sodium increasing of pigment content in barley is observed on the seventh day. The red laser light has a similar stimulating action: the chlorophyll content of barley plants increased after the red laser treatment of barley seeds. However, the chlorophyll contents were depressed when the seeds were exposed to far red light with wavelengths of 754±10 nm. Using these factors, one can manage the content of chlorophyll and sodium-potassium balance in the initial stages of barley ontogenesis in the technology of barley juice or the powder for a healthy and proper human diet.

Abstract
Summary. A series of experiments on the preparation of fondant sweets with partial replacement of sugar by 2-4 % of chicory semi-product were carried out. The analysis of differential and integral distribution curves of particles and sucrose crystals in fondant showed that dispersity reduces with the increase in the chicory content. The effect of fructose and fiber on fondant structure formation was evaluated. A fructose, being an antycrystallizer, delays the crystal structure formation, the fiber due to the high hydrophilicity and water retention capacity on the one hand enhances the supersaturation of the liquid phase, and on the other hand increases mass effective viscosity, which results in the formation of the crystal structure and the liquid phase of high viscosity. Fondant rheological characteristics were defined. Analysis of fondant mass flow curves with powdered chicory semi-product showed them to be pseudo plastic rheological bodies regardless of the recipe. Structural and mechanical properties of the fondant mass during molding depend on the moisture and other liquid components contents, temperature, strain rate, mechanical impact duration, etc. Studies of fondant mass structuring process in room conditions (20 °C) showed that structure formation process accelerates with increase in chicory concentration and the plastic strength of sweets is significantly higher at 3% chicory content as compared to 2 % content. A comparative analysis of fondant sweets quality indexes with various chicory dosages was carried out. Increase in dosage of additives in sweets increases the percentage of reducing substances that slows drying of products during storage and extends their shelf life. The increase in dosage of additives in sweets increases the percentage of reducing substances that slow drying of products during storage and extend their shelf life. The liquid phase content is directly proportional to the dosage of chicory. The technology of making fondant sweets with addition of roasted chicory semi-product while tempering fondant is developed. High nutritional value product was obtained and technological characteristics of production were enhanced by increasing the viscosity and the plastic strength of fondant . The duration of the fondant sweets structure formation while proving significantly reduced, and scrap rate decreased.

Abstract
Summary. Influence of the nature of a sorbent and acidity of solution of the irreplaceable coded amino acid – methionine on its interaction with phosphate ion exchangers KRF-5p and KF-7 in the protonated form with use of calorimetric, sorption and spectroscopic methods is studied. With use of the equations of isotherms of an ionic exchange, material balance and constants of dissociation of amino acid exchange and not exchange sorption capacities are calculated. It is established that irrespective of number of functional groups in a cell of a polymeric matrix, coefficients of sorption balance for both cation exchangers are close, and values of sorption capacity on anion of methionine are slightly higher, than in a bipolar form. The direct calorimetric method determined enthalpies of sorption of methionine at various extents of filling of an ion exchanger, is shown that at identical extents of filling of sorbents of an enthalpy of sorption is one KF-7 lower, than on KRF-5p. The conducted researches allowed to assume that from sour solution at low extents of filling the bipolar ion of methionine is absorbed, an ion of hydrogen of the protonated ion exchangers, not forced out in solution, and passes to carboxyl group of amino acid, neutralizing its negative charge. From the alkaline environment at low concentration of methionine ion-exchange sorption with transfer of a proton from ionogenic group of the cation exchanger to carboxyl group of methionine is most probable. It is established that sorption of amino acid is influenced, mainly, by an arrangement of active groups in a matrix of a sorbent and a form of the absorbed amino acid. It is shown that primary sorption centers are functional groups of ion exchangers, and additional – the absorbed amino acids.

Summary. In the prevention of gastric diseases flexible optical fiber harness with camera and lighting after its extraction from the stomach is subjected to disassembly and continuous sterilization. Protection flexible optical fiber tourniquet, disposable and transparent sheath reduces the duration of the disassembly and sterilization. As the material for the shell of the recommended developed by the Voronezh branch of the FSUE "NIISK" high-styrene block copolymers Styrotep-65. The aim of this work was the development of technologies for films, protective shells of TEC and estimation of their technical parameters. As a benchmark comparison was tested extruded film Styrotep-65. The orientation of the macromolecules of the polymer along the sleeve during extraction provided the anisotropy of the properties of the film along and across the sleeves. In the study of properties of solutions of thermoplastic elastomer is established that the increase in solution viscosity provides greater film thickness in a single dunking them in forms. We investigated the effect of the concentration of a solution Styrotep-65 in toluene and the speed of rotation of a spindle of a Brookfield viscometer PV-E on their viscosity. With increasing concentration of the polymer solution with 19,0 to 26.8 % of the mass. the level of viscosity was increased from 104 to 330 MPa•S. In the interval of increasing the rotational speed of the spindle from 2.0 to 10.0 rpm viscosity solutions is not dependent on the concentration increased due to manifestations of thixotropy. A further increase in the speed of rotation of the spindle 10 to 100 rpm did not affect the viscosity of the solutions. This is true for ideal fluids. Film cast on a horizontal surface of the cellophane from a 10 % toluene solution, was characterized by lower strength than extruded, but with a large elongation at break. Determined the impact of the multiplicity of dipping forms in solution and polymer solution concentration, layer thickness and nature of the substrate on the elastic strength properties of the films. Determined the impact of the multiplicity of dipping forms in solution and polymer solution concentration, layer thickness and nature of the substrate on the elastic strength properties of the films. Maximum strength and the highest elongation at rupture of membranes achieved at three times the dunking form in solution Styrotep-65 with a concentration of 19 % of the mass. The increase in the number of dives forms in the solution was reduced scatter of shell thickness. Under higher magnification, the diameter of the fixed forms of the manifestation of the anisotropy of the properties in the longitudinal and transverse cross section of the membranes due to the orientation of the macromolecules of the polymer along the transverse perimeter of the shell. Confirmed that the increase in the shell thickness leads to a decrease of the translucent ability, measured by a gloss FB-2 and Mono-Spectrum SF-56. Noticed a decrease in light transmission when the thicknesses of the membranes more than 0.15 mm. It is shown that with increase of the wavelength of light grew exponentially. The increase in the thickness of the shells Styrotep-65 from 0.14 to 0.19 mm resulted in a slight decrease in light transmission in the visible and infrared wavelength range from 450 to 750 nm. In the method for casting membranes, determined their optimal thickness based on elastic-strength indicators, identified the effect of the anisotropy properties of the membranes in the longitudinal and transverse cross-section.

Abstract
Summary. The concentrated sodium sulfate solution is formed during the processing of waste battery scrap. A promising way to further treatment of the concentrated salt solution could be the conversion of these salts into acid and bases by electrodialysis, that can be reused in the same technical process cycle. For carrying out the process of conversion of salts into the corresponding acid and base several cells schemes with different combinations of cation, anion and bipolar membranes are used. At this article a comparative analysis of these cells is carried out. In the cells there were used the membranes МC-40, МА-41 and МB-2I. Acid and base solutions with higher concentration may be obtained during the process of electrodialysis in the circulation mode, when a predetermined amount of salt in the closed loop is run through a set of membranes to obtain the desired concentration of the product. The disadvantages of this method are the high cost of buffer tanks and the need to work with small volumes of treated solutions. In industrial applications it is advisable to use continuous electrodialysis with bipolar membranes, since this configuration allows to increase the number of repeating sections, which is necessary to reduce the energy costs. The increase of the removal rate of salts can be achieved by increasing the process steps, and to produce a more concentrated products after the conversion step can be applied electrodialysis-concentrator or evaporator.

Abstract
Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

Abstract
Summary: The analysis of the foreign economic theory and practice of antimonopoly regulation, the principles of the Russian civil law and the antitrust law, allows to formulate a number of the basic principles and approaches to an assessment of influence of different types of the contract relations on efficiency of use of public resources, welfare of consumers and the competitive environment, the research basis presented in this article also consists in it. Support of the competition is guaranteed by the Constitution of the Russian Federation, is one of bases of the constitutional system of the Russian Federation, and also relevance of a subject of research is confirmed by a constant priority of a state policy it. Development of the competition in economy is a multidimensional task which decision substantially depends on efficiency of carrying out a state policy in a wide range of the directions: from macroeconomic policy, creation of favorable investment climate, including development of financial and tax system, decrease in administrative and infrastructure barriers, before protection of the rights of citizens and national policy. Due to the complexity of a task dynamic landmark approach to work on development of a competition policy in connection with development of contract forms of joint activity of small and large business in the Russian Federation and to formation of the respective directions is necessary. For research by authors of research the following methods are chosen: a statistical method, a reference method to value, a comparative method, system approach, a historical method and a method of the economic analysis of the public relations and the right. Research covers the latest sources in the field reflecting the last economic and standard and legal changes, in particular, them treat: the statistical given, expert estimates, regulations, acts of judicial and administrative practice, scientific publications of economists, sociologists and this subject lawyers. Thus, antimonopoly regulation has to consider mutual advantage for the parties of the concrete agreement, a ratio of the extent of the additional benefit received from joint activity by the large company and small firm that is important for the correct qualification of actions of participants - or as abuses of one of participants of the agreement of the dominant position for restrictions of the competition and receiving exclusive profit or as anti-competitive vertical agreement of the parties.

Summary. The article executed the feasibility study of various options for gas treatment. Rapid development of industry and transport worldwide in recent times raises the problem in the protection of habitat environment from harmful waste. In solving problems of flue gas treatment great attention is given to the economic characteristics and recycling techniques for capturing emissions and disposal must also meet the sanitary health requirements: flue gas treatment plants should not cause air or water pollution. The set objective is solved by developing a two-stage wet treatment system for pyrolysis gas based on ejector scrubbers. Their advantage - a central nozzle supply that allows the scrubber to operate on the principle of an ejector pump. Projected plant can be used in enterprises for processing of solid domestic and industrial waste, where there are steam and hot water boilers, whose operations result in contaminated gases emissions obtained with high temperatures. In particular, this installation can be applied at a cement plant in which a large amount of waste gases containing sulfur oxides is emitted. Assessment of market potential for the plant designed to treat waste gases in the cement factory is performed through a SWOT analysis. SWOT analysis results indicate the possibility of the treatment of exhaust gases without a high cost and with high gas treatment efficiency. Plant competitive analysis was done using an expert method in comparison with market competitors. Technical and economic indicators of the plant are presented.

Abstract
Summary. The analysis of structure of starch containing raw materials processing in Russia Federation is provided in the article. There was noted an increase in volumes of corn and wheat processing, however the share of processed potato is still low (below 4%). It was established that Russian starch products and starch sweeteners are on the same level on quality as best European samples and they are very competitive. Market demand in crystalline glucose for food and medical purposes (over 30 thous. tons) is fully covered by import. The volume of import of modified starches exceeds 80 % of total consumption. The biggest volume of import among native starches belongs to potato starch – over 60 %. The article provides suggestions on import substitution of mentioned starch products. The growth of starch production in Russia was accompanied by concentration of production at large enterprises. So, in 2013 over 90 % of glucose syrup was produced at six enterprises, over 80 % of dry starch – at five enterprises. Efficiency of corn and wheat processing into starch and starch products is achieved by production and selling of co-products (dry gluten, gluten, corn germ or corn oil, corn extract, feed products).Development of starch sweeteners production from starch could be achieved by expanding the consumption areas of different kinds of glucose syrup and production of glucose-fructose syrups as full substitute of sugar, providing import substitution of sugar, crystalline glucose of food and medicine purpose, deep processing of glucose into polyols (sorbit, maltit), polylactites, aminoacids.
