Efficient drying methods and post-harvest processes are crucial to reduce waste in fruits, vegetables, and agricultural products. Factors like moisture-related deterioration, climate change, mishandling, delayed shipping, improper storage, and sales delays contribute to post-harvest losses and quality degradation. Solar dryers, especially indirect-type solar dryers, provide a practical and environmentally friendly way to preserve these goods. In comparison to other types of solar dryers, indirect-type dryers have a number of advantages. This review focuses on evaluating the performance of different configurations of Indirect-type solar dryers in terms of drying time, maximum air temperature, drying efficiency for collectors, and overall dryer efficiency. The influence of various operating conditions on the thermal efficiency of Indirect-type solar dryers is also investigated. The study provides detailed information on the sensible and latent storage units and materials used in Indirect-type solar dryers, including those operating through natural or forced convection. The review also explores the utilization of advanced technologies, such as desiccant systems, recycling processes, the use of Nano fluids and nanoparticles, and thermal energy storage, to enhance the thermal performance of solar dryers. Additionally, the paper examines potential difficulties and suggestions for selecting, using, and testing thermal storage for indirect-type solar dryers. In summary, this review provides a comprehensive examination of indirect-type solar dryers, and their performance. It highlights the potential for improving drying efficiency through the integration of advanced technologies and thermal energy storage.

The drying of food products is an essential step in the preservation ofcrops and agricultural by-products that serve as raw materials for numerous end applications. Solar drying with Phase Change Material (PCM) is an efficient low-energy consumption processin the post-reapingstage, reducing food deterioration. A customized solar dryer setup was assembled usingCudappah (black) stones as the baseof the drying chamber to facilitate the absorption of solar energy on its surface. Theorganic paraffin wax, with a melting point of 60℃,was used as PCM in the solar dryer. The novelty of the study is the application of a PCMin asolar dryer to improve the effectiveness of drying and decrease the absolute drying period and the microbial content in the dried food products. The study compared the drying characteristics between open sun drying, solar dryingwithout and with PCM (100 and 200 grams). The fabricated setup was utilised for drying coconut using a PCM-based solar drying method.The coconut was dried from an initial moisture content of 55.5% to a final moisture content of about 9%. The prototype dryer modelminimized the use ofthe workforce,avoided improper drying,and decreased the absolute drying time. A Total Plate Count (TPC) test was conducted to characterize the microbial content in the dried coconut.The microbial count decreased with the use of 200 g PCM as the use of PCM retained the heat for a longer time in the chamber. The drying time of the coconut was decreased by about 28 and 52 hours by installing of about 100 and 200g of PCM respectively. The drying time of the coconut decreased with an increase in the amount of PCM in the solar dryer. The sensory characteristics like colour, taste, flavour, quality, and texture of the solar-dried coconut sample were superiorto the sun-dried coconut sample.
