VereshchynskyiIn the given article the existing technologies of hulled oats grain processing into groats products were analyzed. The possibilities of using new breeding varieties of oats to improve existing technologies were analyzed. Advantages using naked oat varieties for the production of groats and flakes were considered. Results of research influence intensity of pearling and water heat treatment on yield of pearled groats and its quality indicators were shown. The high efficiency of use naked oats for the production of pearled groats with regulated quality indicators was determined. It was found that the technologically expedient moisture content of naked oats before pearling is 12-12.5 %. In the pearling the grain with this humidity depending on the duration of pearling yield of groat estimated to range between 78 94 %. Use as raw materials naked oats increase yield of pearled groats at 1.4-1.6 times in compared to processing of conventional varieties. Modes of preparation of pearled groats for flaking was investigated, feature their influence on the yield and qualities of flaked groats were determined. Analyses of the physical properties of the obtained flaked products were conducted. It was found that the technologically expedient moisture content of pearled naked oats groats before steaming is 17-17.5 %. After steaming groats with this moisture yield of flaked groat estimated to range between 84,3 93,6 %. The main stages of processing naked oats into groats products were determined. The technological scheme of processing naked oats for producing groats and flakes were developed. The technological scheme of processing hull-less barley and naked oats for producing groats, flakes, mixtures of groats and flakes were developed. Technology includes grain cleaning stage, grain water heat treatment, pearling, sorting of pearling products, pearled groat water heat treatment, mixing, flaking, drying, and control of end products.
- ДокументRATIONALE OF TECHNOLOGY FOR THE COMMON AND HULLED WHEAT PROCESSING INTO WHOLE GRAIN FLOUR(2020) D. Zhygunov, O. Voloshenko, N. Khorenzhy, D. Marchenkov, A. BatashchukThe article is devoted to rationale the need of expand the range of flour products and increase its nutritional and biological value by the whole wheat flour production. The article shows the main tasks and problems facing the modern grain processing industry: increasing the utilization rate of grain; reducing the energy intensity of grain processing technological process; and to expand the range of end-products with increased nutritional and biological value. The production of whole grain flour (WGF) will allow expanding the range and increasing the nutritional value of the finished products. Ukraine's state standards for WGF are absent today. DSTU 46.004-99 named «Wheat flour. Specifications» applies only to high-grade flour and dark flour. The studying of Ukrainian WGF quality indicators showed that some manufacturers are guided by DSTU 46.004-99 in the WGF production, other manufacturers control the quality of flour with their own local specifications. Depending on such indicators as ash and particle size, some of WGF manufacturers adhere to the principle of almost 100% entry of all anatomical grain components into end-products. Despite of this, the particle size may vary by the level of the particle size of the dark flour or significantly differ from it. It depends either on the type of grinding machines (millstones or roller mill) or also on the usage of additional bran grinding in the technological scheme. Other manufacturers, in forming WGF to improve its baking properties, adhere to the principle of eliminating a certain amount of shell particles (in bran form). Such flour has an ash content much lesser comparing to the grain, but also its size depends on different structure and modes of grinding process. The purpose of the work is to substantiate the structure of the technological scheme and optimal modes while making WGF. During the research, a number of laboratory grindings of common wheat and spelta wheat into whole-grain flour were conducted. It is established that for the production of WGF it is most expedient to use combined technological schemes with the use of roller machines as grinding equipment on the main systems of technological process and millstones on the last stage systems for the final grinding of intermediate products. Due to the research, it is possible to recommend a scheme consisting of 3-4 roller mill systems and 1-2 millstone systems. The requirements determined for the wheat WGF particle size: top on sieve No. 067 – less than 2.0% and passage through sieve No. 38 – more than 50%.
- ДокументOPTIMIZATION OF FEED COMPOSITION FOR TURKEYS(2020) A. Makarynska, N. VoronaThe article describes that domestic feed products cannot always compete with high quality products of foreign firms. However, the use of imported feed leads to a significant increase in their value and, as a consequence, to an increase in the cost price of the final product. It is established that for the normal development and realization of productivity, turkeys should receive quality and balanced for all indicators of compound feed. Therefore, the task was to develop recipes for turkeys using high quality domestic raw materials. The necessity to determine the complete components characteristics of compound feeds for the finished products production, which meets the requirements of regulatory documents and the consumer, has been proved. There are many indicators and factors that are not taken into account when calculating recipes, but significantly affect the compound feed quality. We have developed compound feed recipes for heavy type turkeys aged 1…4 weeks, 5…13 weeks, 14…17 weeks, 18…30 weeks and over 31 weeks using the “Korm Optima Expert” software complex. The program incorporates the principle of calculating recipes at minimum cost, taking into account the restrictions on the input of each component and the nutrition of the finished product using linear programming by formulas. The expediency of replacing soybean meal in poultry feed due to its high cost for cheaper protein components is substantiated. In order to reduce the cost of compound feed, we have proposed the optimal composition of protein feed additive (PFA) for replacement soybean meal in feed recipes. On the basis of the developed recipes of compound feeds for heavy type turkeys we calculated similar recipes of compound feeds with replacement of soybean meal for PFA in their composition according to the norms of its introduction The quality indicators of finished products are in compliance with the minimum nutritional requirements of compound feeds for heavy type turkeys of a given age. The cost of compound feeds with PFA is much lower than similar with soybean meal. We determined the annual feed consumption of turkeys by growing periods based on the daily feed intake and the duration of each fattening period.
