Abstract

The purpose of the work is to determine the effectiveness of the new solar dryer. The possibility of using a new solar dryer is shown on the example of drying herbs such as basil and vegetables - potatoes. It has been determined that the use of a solar dryer of the developed design requires less time compared to conventional methods of drying in the sun. A comparison of the three types of drying showed that drying with heat storage material has a process time of approximately 8 hours, and drying without heat storage material takes 9 hours, and when drying outdoors under the sun, this value increases to 13 hours, with the residual humidity after drying is 20% (wet weight) while for solar dryers with and without storage material, these values ​​are reduced to 14-15% (wet weight).
