The Ways to Improve the Efficiency of Mobile Solar Dryers

This paper presents ways to improve the efficiency of mobile solar dryers: the efficiency of heated air due to the heat storage capacity of the solar collector, natural convection of the heated air duct and the method of positioning pallets in the drying cabinet for uniform flow of heated agricultural pallets. Dried fruit production in farms of predominantly agrarian countries is based on natural air-sun drying. Exposure to dust, dew, ingress of impurities and direct sunlight, as well as the presence of insects and rodents reduces the quality of the product and requires additional factory processing. The use of solar dryers, although it was a definite step towards eliminating these shortcomings, still depends on their design. Studies have proven the reality of combining the benefits of artificial and natural drying by creating combined solar-fuel dryers. They allow you to realize the benefits of solar and artificial methods of drying, by creating compact, transportable, cheap and less energy-intensive drying systems
