PROCESS EVALUTION OF SEEDS PRE-SEEDING TREATMENT WITH INFRARED RADIATION

abstract 1511907001 issue 151 pp. 1 – 14 30.09.2019 ru 227
The main subject spotted in this article is a calculation method which helps to depict optimal temperature conditions for seeds stimulation by infrared radiation useful for electromagnetic processing and seed-pelleting with perlit next. The analysis helped to depict that the convenient technical aspects of shortwave infrared radiation is in range 0,76-1,4 mcm. This kind of infrared radiation has the greatest penetrating power into the grain to stimulate. According to the methodology a rapid increase of the temperature of seeds after the critical point reaching during IR treatment leads to the properties deterioration of the of thermolabile materials. The temperature gradient during the IR treatment of seeds has the opposite direction of moisture content and depends on the preliminary humidity of the material. This affects the pre-planting cultivation quality of seeds. To avoid overheating and seeds damage there was a mathematical model of the optimal temperature of the IR radiation calculated. As the result of this method there was obtained the calculation of temperature conditions for IR treatment and heating rate depending on seeds humidity. This calculation method helps to define optimal temperature conditions to avoid harmful influence on seeds due to heating. There was data fitting during this method creation and evaluation which defines the effectiveness and perspective of this elaboration

ROBOTIC MEANS IN THE PREPARATION AND DISTRIBUTION OF PROTEIN FEED IN AGRICULTURAL COMPANIES

abstract 1511907019 issue 151 pp. 221 – 231 30.09.2019 ru 199
The purpose of this research is to increase the production of concentrated (protein) feed in agricultural enterprises through the use of electronic equipment or robotics and precise precision livestock technology, which will reduce the unit cost of their production. According to the academician L. P. Kormakovsky, accurate, precision technology enables economical use of material resources, which are feeds and their ingredients in the feed, and to obtain optimum results at the highest cost. The most important direction of development of accurate technologies in animal husbandry is the preparation of complete feed mixtures and normalized feeding of groups of animals formed by its productivity. One of the key conditions of efficiency of precise breeding and the use of sophisticated electronic means of control of technological processes is the quality of the feed. Over the past 15 years, concentrated feed forms have been the basis of the diet of most types of farm animals and is the main reserve for increasing their productivity. The article considers models of robotic means of different countries of producers, used in agricultural enterprises for the preparation and distribution of protein feed. The use of robotics currently makes it possible to facilitate human work, and in some cases to replace it. Replacement of a human in all the spheres of activity, for example in preparation of protein forages, at agricultural companies will allow to increase productivity of forage preparation equipment, quality of forages and to provide agriculture of the country with the domestic forages. However, the production of domestic robotics, which are designed for the preparation of protein feed on the basis of oilseeds (sunflower meal, soybean, etc.) is absent, which is a scientific problem. The production of robotics is most developed in European countries. Robotic means which carry out distribution of protein forages, are applied to a lesser extent at the domestic agricultural enterprises, in connection with their features
