Abstract
In solar dryers, thermal energy is supplied by the unlimited radiation of the sun, so the drying process is highly dependent on different local weather conditions. Different types of solar dryers have been designed and developed in different parts of the world. Among the categories of solar dryers, the indirect type solar dryer has more advantages. The research strategy of this study was conducted in the form of narrative review by searching for related articles in Google scholar search engine using the keywords heat transfer, heat storage energy, phase change materials, solar energy, solar dryer. According to the results of the study, the use of phase change materials in indirect solar dryers provides the quality of dried product in a shorter period of time, so that the air temperature inside the chamber is 4 to 20 degrees Celsius higher than the ambient temperature even after sunset. Celsius above the ambient temperature. It can also reduce post-harvest losses of agricultural products in rural areas of developing countries. This work helps to understand the drying process, different types of dryers and their performance, and energy management in dryers using nanocomposites of phase change materials. The results show the positive impact of these materials in preventing energy losses, reducing costs and preserving nutrients in the dried product
