INTERACTION OF SEEDS WITH VIBRATING SURFACE
DescriptionIn the article we present the results of theoretical and experimental researches of physic-mechanical proper-ties of seeds of vegetable cultures and their interaction with vibrating surfaces of working bodies of sowing devices. The general view of the laboratory installation developed by the authors of the article has been presented

VIBRATING TOOL FOR SOIL TREATMENT
DescriptionOn the basis of the analysis of existing technical means for tillage in this article we propose a new technical means of vibration action including rectangular welded rack with hinge systems, adjusting the depth of tillage. Fixing of the working bodies and working bodies are made in the form of racks with chisels and arrow-shaped claws differ in that there is a shaped hole is made in the upper side of rack where a mounted solenoid is. It is mounted on a rack by means of casing and screws, and the solenoid is made in the form of a coil with a head and spring and communicated with the electrical system of the tractor via the relay-breaker and a regulator are located on the rack. This vibrating tool presumably will lessen the resistance of the soil affecting on the working bodies, will eliminate the sticking effect of elements of working bodies and thereby the quality of the soil tillage will be improved, it will allow to reduce energy consumptions of working process up to 30%, it reduces the emission of harmful substances from combustion of diesel fuel into the atmosphere. The invention relates to agricultural engineering and can be used for tillage on various agricultural backgrounds and with different densities

VIBRATION TECHNOLOGY WITH A LARGE AMPLITUDE OF PARTICLE MOTION OF FEED COMPONENTS
DescriptionThe article has revealed the contradiction between the way of technological impact and the means of implementation of technological transport in existing processes of feed preparation. There has been shown the possibility of eliminating this contradiction by menus of completely new technological equipment on the basis of relative screw drums and the opportunity to improve their productivity. There are no exciters in the offered design of vibrating machines. There is no need for them because the move mend of mass loading particles is provided by the original constructions of relative screw drums committing a rotary motion around its own axis. For implementing of feed preparation process the geometry of the relative screw drum and its dynamism must be individual: the shape, spatial orientation, the impact of forces providing feed components particles simultaneously with rotational-translational and vibrational motion. In the result, the continuously running through the inner cavity of the relative screw drum particles of feed components perform rotational-translational movements with super imposed vibrations inside this drum, due to this process the particles of feed components are mixed intensively

Description
Long-term storage of fruits can be achieved by means of decreasing microbial contamination of their surface as a result of fruits pre-treatment by biopreparations before dispatching for storage. In the current study patterns of influence of fruits pre-treatment with the “Ekstrasol” biopreparation in a number of concentrations of bioagent on the microbial contamination of their surface during storage are revealed. The “Ekstrasol” preparation is a biofungicide, containing the Ch-13 strain of Bacillus subtilis bacteria and their metabolites. As research objects there were chosen apples of a zoned in the Krasnodar region variety called Idared and pears of a zoned in the Krasnodar region variety called Conference, harvested in 2016. The apples and the pears were stored over a period of 6 months in the low temperature conditions. Samples were withdrawn every month over the period of storing. The species composition and quantity of the most prevalent microorganisms, potentially causing the spoilage of apples and pears during storing, were identified. The optimal concentration of the bioagent, which provides the maximal decreasing of microbial contamination of fruits’ (apples and pears) surface, is established – 106 CFU/g, dosage of solution – 1 ml per 100 g of fruit

Description
In article the data of researches on studying process of hydrolysis - extracting of pectinaceous substances from inflorescence sunflower are resulted. For the most full extraction of pectinaceous substances agents used various. At carrying out of process changed its parameters - temperature, рН environments duration, etc. As comparable results accepted parameters: « an output of pectin » and « gelling ability ».
