DETERMINATION OF METALS CONSISTS IN REGUL, THE RAW RICE SORT
DescriptionThe content of metals in raw rice is determined. Inversion voltammetry (IVA) was carried out in an accredited laboratory on the "Ta-Lab" device of the company "Tom-Analit" LLC according to the approved method of ERD F 16.1: 2: 2.2: 2.3.46-06. Silicon dioxide is determined according to ERD F 16.1: 2: 2.2: 3.65-10 and humidity according to GOST 5180-2015. Preparation for the IVA is illustrated. Voltammograms of the potential difference of the chloride-silver reference electrode are compared with the current strength of the indicator mercury-film electrode of electrochemical cells. It has been established that the main metals of the raw rice called Regul grown in the Krasnodar region are: copper 1.6 ± 0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5 mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and silicon dioxide 6.5 mg/kg. The presence of iron is associated with the wear of gravity. The content of zinc, manganese and silicon dioxide corresponds to this type of grain. The presence of copper and lead is associated with the absorption of heavy metals from the soil

ESTIMATION OF CONSUMER PROPERTIES OF DELICACY FROM RABBIT MEAT
DescriptionOne of perspective variants of development of the meat industry can become the production of foodstuffs from untraditional kinds of the meat raw materials such as the rabbit meat, which has a high protein content with a full number of essential amino acids, broad spectra of the mineral substances and vitamins and reduced fat content. Therefore, a demand on the rabbit meat has been increased significantly in the past years. Rabbit meat is widely used in various culinary dishes of the dietary nutrition. Rabbit meat is used in limited scales for production of sausages. The production of the delicacy sterling foodstuffs from the rabbit meat, that are capable for long-term storage, is almost not developed. The regulated requirements for quality of rolls that are included in Technical Conditions are set up in accordance with the developed recipe and technology of production of the smoked-boiled rolls from the rabbit meat. All the foodstuff samples gained high scores on the organoleptic estimation. The foodstuffs satisfy the requirements for chemical composition: mass fraction of protein – no less than 20%, mass fraction of fat – no more than 25%, mass fraction of moisture – no more than 65%. The developed delicacy foodstuffs have a high nutritional and biological value

INNOVATIVE-TECHNOLOGICAL PREREQUISITES OF GRAIN COMPETITIVENESS IMPROVEMENT
DescriptionThe systemic links that depend on mechanization, which affect the growth of the cost price of field crop production were proposed and their analysis was made. Three main blocks of the basic reasons for production costs growth (machinery and materials cost rise, agroecological potential underutilization, agrotechnologies non-observance) disclose agricultural machinery and agrotechnologies of field crops negative aspects that are being used, and also explain agro-potential underutilization causes on the example of the Krasnodar region. The irrational nomenclative list of machines in the current system was analyzed, which not only raises field crop production cost price, but also negatively affects the soil fertility due to its reconsolidation and spraying. Requirements for production processes mechanization means, taking into account their cost price reduction, were formulated. The possibilities for optimizing of the field works timing performed by the proposed agricultural machinery, their quality improving and product damage reducing, as well as work complexity with coinciding terms, streamlining and rhythmicity of processes were formulated. Taking into account the system approach, the imbalance between the agro-industrial complex and management forms was reflected in the weak interrelation of their interests with state interests, which also affects the cost price of production. The negative aspects of the machine system for the mechanization of field crop cultivation were revealed. A special effect should be expected from the proposed combination of technological operations in one pass of the machine across the field due to full-scale adaptations to machines, the ratio of the park of caterpillar and wheel tractors and the work complexity. On the basis of these studies, proposals for traumatization reducing of grain by harvesting equipment and the cost of crop losses from trauma, as well as the regularities of the area of damage to grain from grain vitality have been substantiated. The reasons of production cost price increase are connected with attracting investment issues and managing innovative activities of introducing priority means of mechanization (concessional lending, subsidies, etc.)

WINTER BEEHIVES ELECTRIC HEATING ADAPTIVE TECHNOLOGY
DescriptionThe article is devoted to increasing beekeeping’s earning capacity with rigging and automation of technological processes. Winter is the most complicated and critical period in beekeeping. It influences on further productivity of bee colony. Winter period has specificity – bees are gathering in winter cluster and sustaining temperature in 24…32 °С range inside. This temperature is depending on fluctuation of outside air temperature. For passing winter without complication electric heating is used. Cluster geometry in winter is changing constantly and for optimal regime of electric heating we need to take it into account. Additionally, bees’ activity changing beehive’s microclimate and it’s important to know when beehive’s microclimate adaptive control system is developed. Conducted researches allow us to get basic equations which characterizes microclimate with taking into account of winter cluster’s variable geometry. The equations establish linkage basic parameters of beehive, winter cluster, internal air between outdoor air. Simulation results may be used for adaptive heating control system programming. Additionally, it may be used in special-purpose software for beehive’s microclimate simulation

Description
The tillage with moldboard plows is one of the energy-intensive operations in farming. In view of this, the search of the energy saving solutions and tillage aggregates receives priority. The use of rotary tillage tools based on the working body-mover with elliptic blades, which horizontal soil reaction parts are directed to favoring grade of the aggregate, and, therefore, apart from the performing engineering perform the body-mover functions, - is one of the effective ways of the energy cost reduction. The authors offer the development of the rotary cultivators based on the working body-mover with elliptic blades. The change of their design values allows the development of various profiles tools. The use of these working bodies based on rotary cultivators will allow the energy cost reduction by the tillage process, especially in the compartments of terrain, as the use of tractors with moldboard plows for the main tillage is problematic. In many cases, these lots must be labored manually. The article describes the construction, generalizes the mechanical specifications and working modes of the rotary cultivator at the main tillage
