“…The dryer Cetina-Quiñones et al [52] introduces limestone and beach sand as another thermal storage material that was able to provide the additional heat during the downtime of solar availability. Dryer [6], [8] and [46] depends on grid electricity to power up the heater module to provide additional heat to increase the temperature inside the drying space. Finally, comparing the number of authors from both types of solar dryers presented in Table 3 and Table 4 implies that the indirect type of solar dryer receives more attention than the mixed type of solar dryers.…”

“…There are two main solar energy applications; one application uses this energy to convert it to electricity using photovoltaic (PV) panel, and the second application is converted it to thermal energy used for drying through a device called solar air collector [46]. Figure 2 illustrates the different types of solar dryer systems, including direct type, indirect type, and mixed mode, and their variations.…”

Agriculture contributes to large export earnings for many countries and provides food all over the world. However, most agricultural products need some post-harvest processing, such as drying, to extend their shelf life while still maintaining their respective nutrient quality. One popular post-harvest processing method is drying using solar energy. It is a type of renewable energy that is abundant and free. Conventional dryers use grid electricity and can be expensive to operate. Consequently, there is a growing need for cost-effective solar-powered agricultural dryers that is reasonable for smaller-scale farmers. Although current solar dryers are still not on par with modern electricity-powered dryers, solar dryers have lower running costs and are sustainable and able to generate electricity. They can also be used practically anywhere with abundant solar energy. As numerous solar drying technologies have been proposed over the past decade, it is necessary to assess the current state of solar drying technology in the agricultural sector to identify current advancements and potential research gaps. In this paper, a review of existing solar dryers mechanism and the state of the art of solar drying technology research for agricultural products is presented.
