Abstract

The article presents the results of research on drying fruits and vegetables using polyethylene-ceramic composite material as a coating for a solar solar dryer. A comparative analysis of the drying efficiency in solar dryers based on composite and traditional polyethylene coating is provided. The conditions and methodology of the experiments are described. The results of comparison of drying time and residual moisture of products were obtained. A higher efficiency of the drying process is shown when using a composite material.
