The Use of Electroactivated Air to Intensify Grain Drying by Active Ventilation

Аннотация

The post-harvest grain processing process is one of the most important in agricultural production technology. It is post-harvest processing that contributes to the production of high-quality products, long-term and effective preservation of these products, right up to the harvest of a new crop. Keywords: Drying of wet products, biological activity, Drying, high humidity, recirculating drying, vacuum drying, Electroactivated air, criterion model. frequency currents, drying grain under the influence of Introduction: One of the main objectives of agricultural an electric field, and many others. Recently, methods production is to increase the production of grain crops of exposure to dried material with electroactivated air to meet the growing food needs of the population. have been increasingly used. The post-harvest grain processing process is one of the Electroactivated air is used in agriculture for drying, most important in agricultural production technology. increasing the nutritional value of feed, temporary It is post-harvest processing that contributes to the storage, and disinfection. The analysis of the works production of high-quality products, long-term and showed that the inconsistency of the data obtained by effective preservation of these products, right up to the different authors on the concentrations of ozone and harvest of a new crop. aeroions for various technological processes does not Post-harvest grain processing consists of several allow us to identify the main reasons affecting the stages: cleaning, sorting and drying of wet products. efficiency of processing processes. The available The amount of moisture contained in the grain affects research results allow us to talk about the effectiveness its biological activity, quality and safety. This is the most of using aeroions to intensify grain drying, but they are important and reliable factor in regulating the vital also contradictory and require clarification of activity of grain. In order for the grain to be stored well, processing modes. its humidity should not exceed the conditioned In this regard, the following ways are outlined to humidity, which, even in good weather, the humidity of intensify grain drying by active ventilation using the harvested grain is 4-6% higher than the conditioned electro-activated air: humidity. In adverse weather conditions, grain moisture reaches 25-35%. Up to 20% of the crop is lost 1.

Development of grain drying modes by active To obtain grain with conditioned humidity and reduce ventilation using electro activated air. energy consumption in agricultural production, the In accordance with the above, the purpose of the study following methods of grain drying intensification are is formulated in the article.: used: recirculation drying, preheating, vacuum drying, drying using infrared radiation, drying with high Development of energy-saving technology for grain International Journal of Management and Economics Fundamental 98 https://theusajournals.com/index.php/ijmef International Journal of Management and Economics Fundamental (ISSN: 2771-2257) drying in active ventilation units using electroactivated mechanisms of action of electroactivated air on grain air. drying are presented. A hypothesis is proposed on the mechanism of intensification of grain drying using EAW The object of the study is the process of drying grain with cyclic supply of aeroions. The purpose and with electroactivated air in active ventilation units. objectives of the work are formulated. The subject of the study is the patterns of heat and The scientific novelty of the research results is moisture exchange in the grain layer during drying of represented by: grain with electro activated air. - a mechanism for intensifying grain drying using EAW The following task has been set: with cyclic supply of aerations; - To conduct theoretical studies on the description of - the criterion dependence of the change in the the effect of electro activated air on the processes of concentration of ions in the air when using EAV in heat and moisture exchange in the grain layer, on the active ventilation installations, the criterion model of intensification of drying. To formulate a hypothesis grain drying with electro activated air and the criterion about the mechanism of intensification of grain drying of electro activation of the grain layer during EAV using EAW with cyclic supply of aerations. To develop a drying; mathematical model of the drying process of the grain layer under the cyclic action of EAW. - equations of the drying rate of t
