THE EFFECT OF PLANT FOOD ADDITIVES ON THE PROPERTIES OF WHEAT FLOUR AND DOUGH

abstract 1281704009 issue 128 pp. 154 – 166 28.04.2017 ru 542
The article presents data describing composition of macronutrients and food additives "Apple Powder" and food additive "Pumpkin Powder" obtained from secondary resources processing of apples and pumpkins with innovative technology that ensures their high antioxidant activity. Introduction of the studied food additives in wheat flour provides a boost of its antioxidant activity compared to the control (wheat flour without any additives). We have revealed that the introduction of the studied food additives in wheat flour provides a strengthening effect to the gluten flour, while dietary Supplement Powder called "Apple" has a strengthening effect on the gluten of wheat flour compared with a dietary Supplement called "Pumpkin Powder". We proved a positive impact of food additives on the gas-forming ability of wheat flour and water absorption capacity of dough; at he same time, with the same dosage of additives, water absorption capacity of dough with the introduction of additives of "Pumpkin Powder" is higher than this figure with the introduction of the additives of "Apple Powder", due to the higher content of pectin in the additive "Pumpkin Powder " compared with the additive "Apple Powder", having a high water-holding capacity. We have found that the dough with the introduction of the investigated supplements has the best rheological properties in comparison with control samples. The obtained results allow us to develop evidence-based formulation and technological modes of production of bakery products enriched with antioxidant properties, with the use of food additives called " Apple Powder" and "Pumpkin Powder"

abstract 1281704011 issue 128 pp. 188 – 199 28.04.2017 ru 347
Condition monitoring is a necessary element of the transport and special machinery in agriculture. The task of the control operations other than the determination of the technical state of the object is to determine the required amount of work, as well as rational amount of collateral the repair of which could be combined with the next maintenance. Based on the results of processing of the information, we may generate requests for service. In the conditions of uncertainty of receipt of requests for servicing of individual machines, estimated volumes and timing, we have am appropriate development of applied technique of justification of the number of diagnostic posts for interactive control of a technical condition of vehicles and special machinery in agriculture. The presented methodology is based on probabilistic methods, and allows the quick optimization of the number of existing posts interactive diagnostics in the enterprise, if necessary, translating the existing posts in "standby" mode, or Vice versa, returning from a reserve in "work" mode. The production and technical base of the enterprise service based on the specific assumptions are considered as a system of mass service (SMO), and the function of such a SMO – as the process of mass service. The process of queuing as applied to interactive diagnosis are "Markov" processes "death and reproduction" with a finite or countable number of States and continuous time. To describe the states of the system we use the system of the Kolmogorov equations for steady state of "Markov" process. On their basis, we have determined average queue length, time of stay orders in the queue, number of busy channels and the bandwidth of the CFR. Using the intensity of the requests and the service time of a single application for specific equipment, the article establishes the efficiency of online diagnosis posts. The result of the proposed applied methodology enables timely decision-making about the need for reconstruction or technical re-equipment of the company

RESEARCH OF MODERNIZED BD-4M HAULM SHREDDER WITH ARTICULATED KNIVES

abstract 1281704012 issue 128 pp. 200 – 213 28.04.2017 ru 617
In the general complex of mechanized works when growing potatoes, potato harvesting is one of the main operations. The efficiency of potatoes growing at the farm largely depends on harvest quality and crop retrieval. When harvesting potatoes with potato harvesters their productivity largely depends on the state of potato haulm. In a case of evolved and laid haulm the harvesting machines productivity falls sharply due to working organs clogging and in some cases their work is not possible at all. Therefore, to facilitate the work of potato harvesters it is necessary to remove potato haulm before harvesting. But the process of haulm removing is very laborious, including several operations, such as mowing, raking and transportation, each of which is performed by a separate machine. The appearance of domestically made rotary-type machines like KIR-1.5, UBD-3 and BD-4 at the end of 1950-1960 made it possible to mechanize the harvesting process of potato haulm. But it was noticed in the operation that rotor machines have a number of drawbacks caused by imperfections in the rotor design, its kinematic regimes, lack of balance and some others. Therefore, studies aimed at improving the design of rotary-type machines seem to be very important. To achieve this goal some theoretical and experimental studies and lab and field tests of the modernized four-row shredder have been carried out. When studying methods of mathematical analysis and elements of classical mechanics were used. Some modern methods were applied in the lab and field tests. The modernized haulm shredder BD-4 was tested at JSC “Avangard” in Ryazan district

MATHEMATICAL MODELING OF THE UNIFORMITY OF WATERING WITH A SPRINKLING MACHINE OF CONTINUOUS PROGRESSIVE MOVEMENT ACCORDING TO THE RESULTS OF THE TEST OF THE UNIT WITH A RADIAL METHOD

abstract 1281704014 issue 128 pp. 229 – 239 28.04.2017 ru 334
The aim of the study was to improve evaluation of the uniformity of irrigation with a machine of continuous translational motion, according to the test results of the apparatus with radial methods. Research method – mathematical modeling of the running of four machines of circular actions on a device of continuous translational motion using the result of the tests of the device with a radial method. The algorithm of calculation, recommended by the standard ISO 7749-2-2004, has been improved to minimize manual calculations and measurements. The algorithm is implemented in a computer program. Program of CDU(B) implements an advanced algorhythm. The program calculates a matrix of irrigation doses on meter squares area of spray irrigation between the positions of the two devices. The progressive movement of the machine is modeled by summing the doses in column-major order with constant X. At vector doses after the passage of the machine, it calculates the coefficient of uniformity of irrigation by Christiansen. The calculation is performed at different steps of the installation of devices, and so it determines the optimal location of them. The improved algorithm of calculating the figures of sprinkling uniformity using the test results for devices using a radial method was implemented in the program of the CDU(A) [1]; it allows to choose the optimal step for installation of devices. The algorithm of calculating the uniformity in the step of installation of the apparatus on the pipeline which is greater than the radius of the irrigation apparatus simulates the operation of two devices. During the installation step of the apparatus of smaller radius than irrigation apparatus, we model the work of four adjacent devices. The optimal step of installation of i-Wob is 14.5 meters, which is 1.75 times greater than the radius of the irrigation system and 1.5 times greater than the pitch of stationary devices with the same tolerance on the uniformity. Two-nozzle devices, which assessment standard does not meet the requirements of the uniformity of irrigation at the drive of the translational motion ensures a better distribution in the pitch of less than 24 meters

MODERNIZATION OF ZIL-5301 FOR USE IN AGRICULTURE

abstract 1281704015 issue 128 pp. 240 – 248 28.04.2017 ru 424
The role of transport in agricultural production is considerable. It is a connecting link in a single technological chain of agroindustrial complex of the country. The successful production activity of agricultural enterprises depends largely on the proper use of available forces and means. One of such means is machine-tractor fleet relating to technical basis of agricultural production. Its functioning is reflected in the whole cycle of production, from planting and ending with cleaning. Therefore, the use of the machine and tractor must ensure receipt of the highest possible efficiency at the lowest cost, as production cost agricultural production includes in its membership the costs of mechanized and transport works, which should be kept to a minimum. In this regard, transport processes should be carried out the most rational means. Rational application of those or other vehicles is based on ratios of basic load ratings, adaptability to the changing road conditions, terrain, improving functionality, improved adaptation to technical operation in the conditions of agricultural production. When choosing a vehicle, special attention must be paid to the size of the economy, the direction of its activities, the structure of commodity products, and the degree of its centralization. For successful economic activities of the agricultural enterprise it requires a different carrying capacity and terrain vehicles. At present, the majority of the automobile park of agricultural enterprises is cars and trains of general purpose, which have large load capacity and low permeability. In the agricultural enterprises of the Ryazan region today there are about 4.5 thousand commercial vehicles, mostly models of GAZ, KAMAZ and ZIL. The issue of reducing the cost of transport operation should be individualized for each sector because of its distinctive features (activity, volume of traffic, the structure of commodity production, the state of farm roads, etc.)

WAYS OF OPTIMIZING THE AMOUNT OF CHEMICAL ADDITIVES IN POROUS ARBOLITE CONTAINING FOAMED POLYSTYRENE GRAVEL AGGREGATE

abstract 1281704017 issue 128 pp. 258 – 267 28.04.2017 ru 513
The article deals with studying the ways of optimizing the amount of chemical additives in the wood-concrete material, i.e. arbolite, which contains foamed polystyrene gravel aggregate. To make arbolite honeycombed structure more conglomerated a nonreactive aggregate, i.e. hogged chips, has been partially replaced with foamed polystyrene gravel aggregate which has a mean particle size equal to a concrete pocket size. The article also deals with various additives to be used, taking into account the nonreactive aggregate type and its quality, the composite density and its reinforcement level. All chemical additives have been chosen to make the initial material more porous, to produce a film covering the aggregate surface and to speed up the process of concrete hardening. To solve to above problems a series of experiments was carried out, the latter studied various combinations of factors changing at certain levels. The results of studying the foamed polystyrene gravel aggregate influence on the arbolite structure and its characteristics were used to make a choice of the arbolite composition. The main criterion of the optimal amount of chemical additives has been considered the arbolite strength. The experimental data processing has resulted in the finite regression model which describes the chemical additive amount influence on the arbolite strength. The tables in the article show the levels of technological factors varying and the matrix of planning the experiments to be carried out in order to optimize the chemical additive amount. As a result of the research accomplished the optimal amount of chemical additives has been determined which enables to produce the arbolite with some foamed polystyrene gravel aggregate in its composition

abstract 1281704026 issue 128 pp. 364 – 374 28.04.2017 ru 339
The subject of study of this work was learning algorithm of neuro-fuzzy systems with different membership functions. In the prior works there are no published studies of such studies, making it difficult synthesis of neuro-fuzzy control system with new objects in the application of biotechnology, including technological agribusiness entities. A comparative analysis of learning algorithms of neuro-fuzzy system with different membership functions using the method of error back propagation and а hybrid method. For this we used a training sample that contains data of temperature and concentration of dissolved gas in the culture liquid: oxygen (pO2), carbon dioxide (pCO2) of a biotechnological process. It is shown that the hybrid method carries out training of a neural network for the number of periods is 23 times smaller than the algorithm back-propagation errors. The studies found that the two-sided Gaussian membership function provides the smallest learning error of the network δ equal of 3,28•10–3, compared to the other, giving the largest error of training the neural network δ=0,138. Therefore, the task of running the fermentation process effective is the use a hybrid method of education and two-sided Gaussian membership functions. According to the research, we can conclude that for the adaptation of neuro-fuzzy network ANFIS and fuzzy inference system Sugeno zero order to solve biotechnological process control tasks microbiological production efficiency is to use a hybrid method of education and bilateral Gaussian membership functions
