FUNCTIONAL BEVERAGES CONTAINING PECTIN ON BASED ON CABBAGE JUICE
Description
The article presents data on the development of recipes and technologies for the production of functional drinks based on cabbage juice. Theoretical and experimental justification of the selection of ingredients of plant origin for the modeling of drinks with a high content of pectin substances is offered in the article. The use of carrots, beets and cranberries is considered as an additional raw material for the purpose of expanding the range and improving the organoleptic properties of beverages. The fractional composition of pectin substances used in the raw materials was studied. The expediency of introducing concentrates of pectin substances into beverage recipes, which define the functional properties of beverages and their optimal content in the recipes was determined. The characteristics of basic parameters of new drinks based on cabbage juice are given. The results of the study of the complex forming property of the developed beverages, which confirmed their functional orientation, are presented. Experimental studies have shown that the addition of pectin increases the complex forming property of juices. Complex forming ability of cabbage juice with beet pectin in comparison with the control sample and other samples is the highest. Taking into account additional complex of biologically active compounds based on cabbage juice, this product can be used as therapeutic, prophylactic and chemoprotective

CONSTRUCTION AND CALCULATIONS FOR DEVICES FOR DRYING CHICKEN MANURE
Description
The article presents innovative technologies and developed methods and devices for drying chicken manure. Ways of their optimization on the basis of screw aggregates and a calculation technique for introduction in production are offered. The results of a long-term research into the search for and development of innovative technologies for the construction of a methodology for calculating not only a device for drying chicken manure with subsequent introduction into production, but also a device for drying bulk materials of agricultural purpose are shown. An example of thermal calculation and selection of the parameters of a drying device is shown on the basis of screw aggregates

Description
For different industries, there was a need of creation new equipment and mechanisms with enhanced characteristics. Special requirements are imposed to energetic and mass-dimensional indices of systems of electric drives as one of the main components of such devices. Mass-dimensional and energetic indices due to constructional features and the used management system will allow improving the use of special or controlled asynchronous cascade systems of an electric actuator of axial construction. One of the main difficulties is simulation and design of special systems of the electric drive. In the article, we offer a new approach to determination of magnetic model parameters of the stator of a component of a controlled asynchronous cascade electric actuator of axial construction

ALGORITHM FOR OBTAINING MATHEMATICAL MODELS OF ELECTROMECHANICAL DEVICES
Description
An algorithm for obtaining a complex of mathematical models of electromechanical devices, which can then be formalized and implemented in software, is proposed and described. Until recently, the implementation of this algorithm was possible only with the manual derivation of all expressions, which significantly hampered the work of researchers. The appearance of such programs as Maple, Mathematica and MathCAD provided the possibility to automate the process of obtaining analytical calculations that allows calculating any modes of any types of electromechanical devices, reduces the likelihood of errors and allows you to change accepted assumptions and designations in the developed models. The choice of the MathCAD program (in comparison with Maple and Mathmatica) can be justified by the fact that MathCAD has the most convenient interface, allowing not only to perform mathematical calculations, but also to present the results in ordinary mathematical notation. The analytical results obtained in MathCAD can be immediately included in numerical models
