UDC 662.997 RESEARCH THE TEMPERATURE REGIME IN THE HEAT ACCUMULATOR OF THE LOW-POTENTIAL SOLAR DRYER DEVICE WHEN DRYING THE URIC PRODUCT
Abstract
The limited nature of land resources and the prevention of energy shortages as a global problem require the effective use of renewable energy sources. . The drying efficiency of the main environmental factors - solar radiation, outdoor air temperature and humidity - in the process of drying uric acid products was studied experimentally. During the study, various weather conditions and parameters were tested under control, and how the incidence of solar energy on the surface of the product, changes in outdoor temperature and humidity of the surrounding air affected the moisture content of the product, drying time, and the physicochemical and organoleptic properties of the product were analyzed in detail. At the same time, excessively high temperatures and low humidity lead to deterioration of product quality. As one of these, the use of solar dryers operating on solar energy is of urgent importance. As a result of experimental studies, it was found that fruits and medicinal plants in cabinet-type solar dryers are reliably protected from dust, external pollution and the effects of microorganisms. When the internal temperature exceeds the range of +65…+75 °C, aerodynamic cooling systems are introduced to stabilize the heat balance. The results of the research provide a scientific basis for optimizing heat exchange processes and improving environmentally friendly technologies when using solar energy
