Abstract

Global issues such as energy shortages and food insecurity are intensified by a growing population and considerable losses after harvest, resulting in serious hunger levels. Solar drying presents an efficient, sustainable, and high-quality approach to food preservation, significantly contributing to the improvement of global food security. In the realms of agriculture and the food sector, dryers play a critical role in prolonging the shelf life of crops by extracting moisture, with solar thermal energy being particularly notable for its environmental advantages and widespread availability. This paper is helpful to find out the efficient and successful method for research on indirect solar drying. The strategy is founded on research concerns and other elements that impact system performance, such as dryer forms, dryer size, food-product level of moisture, air flow rate, air temperature, and system efficiency. These types of problems have been compiled from previous research conducted on indirect solar drying. To improve the handling and storage of drying food products without sacrificing quality, all features can be divided into various categories. General, operational, application type, extra equipment and instruments employed, and other characteristics are categorized in the case of an indirect solar dryer. The drying efficiency varies from 9% to 40%, according to the current literature review using the characteristics that are currently accessible for indirect and hybrid sun drying modes. For enhancing the present quality of drying agricultural goods with reduced thermal energy storage ranges while staying within a safe maximum temperature range. It has been demonstrated that manufacturers, designers, and researchers may benefit from the information found in the database of research articles According to data gathered from current studies, installing a PV cell driven desiccant wheel in dryers combined with pebble bed storage is an economical and useful option since it speeds up the drying process, reduces temperature fluctuations and supplies thermal energy during off sun shine hours. It appears to be a suitable solution for addressing global warming and future nutrition rich food preservation needs.
