Description
The article analyzes the existing classification of leveling devices and their design features. We have found that currently the form of the seed layer is achieved with harrowing cultivation in 2 ... 3 tracks , leveling and packing rollers in 3 ... 4 passes units on the field, which leads to an increased cost of fuel, living labor, as well as compaction of arable and subsoil layers of the soil. We have also proved a constructively scheme of a com-bined device capable to form the seedbed in accordance with agronomic requirements in a single pass

Description
There has been developed the design of the single disc centrifugal apparatus with the feed of the granular material along the blades. The scattering disc consists of blades, on the top shelf there is a flat disc with air intake windows (deflector). The purpose of the deflector is to eliminate the reflection of particles at the moment of contact with the blade and create a passing air flow to increase the range of flight of the particles. The analysis of the constructive scheme of the scattering disk showed that the amount of air coming inside the scattering disk is affected by the width of the window and the tilt angle of the deflector body. There was determined the dependence of the window width from the angle of the deflector body and height. Based on the analysis of the design there have been determined the limits of setting the window width and the tilt angle of the deflector body. The angle of the deflector body changes in the rate of 90 to 320 . Increasing the tilt angle of the deflector body leads to a proportional reduction of the window width. There have been set the intervals of variation of factors. There have been chosen the symmetrical composite plan of the second order and have been made a matrix of the experimental design. As a function of the response factor there have been taken a relative accuracy coefficient. The implementation of the experiment allowed us to determine the value of the regression coefficients. The adequacy of the regression equation to the equation obtained was performed by the Fisher test. It was determined that the equation adequately describes the technological process. For the analysis of this equation it was turned to the canonical form by moving the origin to a new point and turning at a certain angle of 14,950. The analysis of the canonical equations allowed the authors to determine the optimal values of the studied factors. The window width of the deflector is 22 - 25 mm, the angle of the body of the deflector is 8 - 120

Description
Nowadays there is a deficit of irreplaceable and physiologically necessary nutrients in everyday ration to a large extent connected with unfavorable environmental conditions and the increase of morbidity of humans of all ages cause the cute necessity in the creation of functional food that is products with additional functions which are healthy nutritive and physiological characteristics. One of the main demands under their creation is in the positive influence of introduced products on the food value of products because they must be enriched with ingredients which have antioxidant properties. Therefore, nowadays the introduction of functional meat-plant products will promote the effective improvement in the direction of prophylaxis of different diseases. In Russia, the concept of healthy nutrition became a part of state politics. The aim of this politics is the conservation and consolidation of population’s health and the prophylaxis of diseases. In this work, there was considered the technology of the production of meat-plant tinned food of functional purpose enriched with nutrients and intended for preventive human nutrition, for those who are in the conditions of harmful influence of environment and professional activity. There were described the advantages of the given developing, there were recommended the introduced into the product components of functional purpose
