RESEARCH RESULTS OF THE DEVICE FOR DRYING AGRICULTURAL CROPS

Abstract

Farms and retailers are not always able to preserve the harvest due to the need to build vegetable stores and the difficulty in observing storage technology. Under these conditions, the way out of this situation is the drying of vegetables. The use of drying allows saving all the taste and almost all the vitamins. Under these conditions, Penza State Agrarian University has developed a prototype device for drying crops, allowing for fluidized-bed drying. However, it is necessary to conduct research to improve the drying process of vegetables with a pneumatic-mechanical dryer with justification for its design and technological parameters. The experimental methods were used in the work: modeling, observation, experiment. Experimental studies were carried out in laboratory conditions on the basis of generally accepted methods in accordance with current industry standards, as well as developed private research methods. Processing of the research results was carried out on a PC using standard computer programs Microsoft Excel, Statistica, KOMPAS-3D. As a result, a model of the drying process was obtained and the optimal parameters of the proposed device were determined.
