The article analyzes the features of drying grain raw materials using a vibrating dryer, in which the drying agent is a mixture of heated air in combination with ozone of a certain concentration. Based on the analysis to intensify this process, we propose to develop a high-performance electronic device for ozone synthesis. 

The scientific study considers oscillations that increase and update the heat transfer surface regardless of the method of supply of the drying agent. Due to this, the removal of moisture intensifies, the drying speed increases. Having conducted a search and analyzed the process of vibration drying, we can say that in the future will progress two main trends in their development. This is the use of vibration in combination with the action of ozone on the raw material entering the drying. 

Ozone interacts with the membrane structure of bacteria, fungi, the structural unit of viruses, which leads to a violation of its barrier function and their death. The bactericidal effect of ozonation is superior to the effect of ultraviolet quartz radiation. Bactericidal effect from quartz irradiation for 60 minutes identical to the bactericidal effect of ozone for 3 minutes Ozone has a high penetrating ability and also shows antibacterial activity against gram-positive flora, Escherichia coli, epidermal staphylococcus. This method is the most effective general method of controlling the dynamic state of the processed raw materials. The analysis allows us to suggest possible solutions for the use of low-frequency oscillations for separation processes and outline the prospects for their application. It is proved that the existing equipment is used with significant energy consumption and high cost. 

The constructions and technologies considered in the work do not completely exhaust the possibilities of using vibration and ozone, although they testify to the expediency of their application and combination not only in agricultural production, but also in other industries in order to intensify processes and obtain quality products.
