STUDY OF VIBROZONATING PROCESS OF GRAIN DRYING AND ENERGY PARAMETERS OF THE INSTALLATION FOR THE REALIZATION OF THIS PROCESS

Abstract

Drying is one of the most important stages of grain preparation for storage in agricultural production. Today the convective drying method is widely used in this technological process. But along with the advantages this method also has a number of disadvantages, one of them is great energy consumption. As a consequence, intensive scientific search is carried out to develop means and methods, aimed at the reduction of energy consumption of the convective method of drying.

Process of the post-harvest treatment of grain, especially, drying is one of the most important processes in the technology of agricultural production. This treatment promotes the obtaining of high-quality products, their long-term and efficient storage till the new harvest.

For obtaining grain raw material of the normal moisture and reduce the energy consumption various methods of drying process intensification are used in the sphere of agricultural production: vibration drying, recirculation drying, preliminary heating, vacuum drying, drying, using IR-radiation, drying by the high frequency currents, grain drying under the impact of the electric field and other methods. From the point of view of energy consumption and quality of the obtained primary products is the usage of the vibrating driers, combined with ozonizing technology, which is the additional factor, contributing to the drying process intensification.

The given paper is devoted to the solution of the urgent problem of the intensification of grain raw material drying and development of new vibro ozonizing complex, which realizes the complex technological impact on the handled medium.

Energy parameters of the developed vibroozonizing complex were experimentally investigated, depending on the mode parameters of the investigated process of grain raw material drying.
