APPLIANCES, TECHNOLOGIES AND EQUIPMENT FOR HAULING OF FRUIT OUT THE GARDEN

abstract 1071503032 issue 107 pp. 459 – 472 31.03.2015 ru 981
An integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ... " and others mentioned in the "Transport Strategy of Russia until 2020"

ANTIOXIDANT ACTIVITY OF FOOD ADDITIVES DERIVED FROM SECONDARY PLANT RESOURCES

abstract 1261702007 issue 126 pp. 109 – 118 28.02.2017 ru 790
The accumulation of free radicals in the human body in excessive quantities is one of the reasons that are known to cause many dangerous diseases and aging. To reduce the negative impact of free radicals to the body is possible through regular consumption of food products enriched with nutritional and dietary supplements containing natural antioxidants such as phenolic compounds, vitamin C, vitamin E and β – carotene. Scientists of federal state budgetary scientific institution "Krasnodar research Institute of storage and processing of agricultural products" have developed a technology for production of food additives from secondary materials generated during the processing of apples and pumpkins. The article presents data characterizing the antioxidant and antiradical activity of food additives derived from secondary plant resources developed and known technology. It is established that the antioxidant activity determined by the amperometric method, and the antioxidant (antiradical) activity, determined by DPPH method, supplements, "Powder apple" and " Powder pumpkin" obtained by the developed technology, is almost 1.5 times higher in comparison with antioxidant and antiradical activity of food additives, obtained by known technologies, because of higher content of antioxidants in the developed supplements. It has been established that the expression of antioxidants and anti-radical activity of food supplements obtained from secondary resources on the developed technologies, can be positioned in a number of (descending): "Powder from the seeds of grapes" → "Apple powder" → " Pumpkin powder"

ANALYTICAL SOLUTION OF THE HEAT PROBLEM OF THE PROCESS OF CENTRIFUGAL BIMETALLIZATION WITH ELECTRIC ARC HEATING

abstract 1301706085 issue 130 pp. 1177 – 1188 30.06.2017 ru 323
At the nodes of the various machines, we use plain bimetal bearings: a steel base - antifriction cladding layer. Bimetal bearings have increased performance. One of the ways of making such bearings is the way of centrifugal bimetallization with heating of the independent electric arc. An important requirement of this technology is a uniform heating of the workpiece along the entire length until the formation of a continuous layer of the molten cladding material. The process of bimetallization require temperature control, since within the movement of the electric arc, low heat or high heat are possible due to heat dissipation from the ends of the workpiece in the installation and from the outer surface of the workpiece to the environment. A viable option the temperature control of the heat process of bimetallization for industrial conditions is to control the temperature of the outer surface of the steel base. It is necessary to solve the heat problem of the relationship between the temperature on the surface of the workpiece with the temperature on the boundary layers. For this purpose the numerical solution of the mathematical model of the thermal process, which includes the heat transmitting equation of Fourier and heat transfer at the ends of the sleeve according to Newton's law. The equivalent coefficients of heat transfer are obtained based on calculated and experimental thermograms. This is a time-consuming work. To minimize the time of fixing the boundary value problem of the thermal process of bimetallization, in this work we present the preliminary modeling based on the analytical solution of the thermal task of bi-metallization

ANALYTICAL REVIEW OF PREVENTIVE MEASURES AND ACCIDENTS’ LOCALIZATION AT EXPLOSIVE STORAGE AND PLANT RAW MATERIALS PROCESSING FACILITIES

abstract 1121508067 issue 112 pp. 939 – 950 30.10.2015 ru 1159
The industrial safety on cereal production is currently important due to the severity of the consequences of accidents occurring to them. It should be noted that, despite the considerable efforts of recent years, awareness-raising and supervisory plan towards preventing their occurrence, the lack of attention of organizations operating hazardous production facilities to comply with the relevant standards and requirements allows us to characterize the recent situation in this area quite difficult, as evidenced by statistics. In this article it is clearly illustrated the qualitative and quantitative expression of such an approach in practice. The conceptual framework is disclosed in the light of efforts to carry out industrial safety examination in the conformity assessment of hazardous industrial facilities according to industrial safety requirements in the Russian Federation. The basic methods and technical means used for the prevention of accidents at hazardous production facilities of storage and processing of plant raw materials provide an overview of domestic and foreign producers. The item-description of the system of protection of buildings and facilities of hazardous production facilities is given taking into account the industry specifics. There are specified the key factors meeting modern technical requirements, cost-based position of enterprises, ensuring conditions for safe operation of the storage and processing of plant raw materials
