“…The assessment of drying efficiency by Silva et al [10] and Cesar et al [20] are 6.10% and 8.20%, respectively. The SMER of 0.616 kg/kWh and SEC of 1.623 kg/kWh have been determined by Ekka et al [16]. Present results of energy performance indicators are well comparable with the earlier research works.…”

“…The PVT solar dryer aims to acquire the most significant amount of energy to be carried by air to the food while also removing the moisture present in the food in the least period. In order to choose the optimal drying method for a given product, the analysis of the impact of airflow and temperature on the system performance is necessary [16]- [18]. As the demand for efficient and sustainable processes grows, energetic and exergetic analysis of dryers becomes increasingly essential to enhance the design and technical sustainability.…”

“…It is the ratio of actual moisture evaporated during the drying process to the total moisture removal capacity of the drying air. It is also called the effectiveness of a solar dryer [ 22 ]. where m a = Mass flow rate of drying air (kg/s), t = time (s), h sat = adiabatic saturation humidity of the air entering the dryer (kg water/kg dry air), and h in = absolute humidity of the air entering the dryer (kg water/kg dry air).…”

Solar dryers have always been criticized for their lower performances. There are numerous ways to define the performance of a solar drying system such as thermal performance, drying kinetics, environmental aspects, economic evaluations, and quality of the dried product. Different modeling techniques have also been developed to design and analyze solar dryers and drying processes. This article presents a systematic, comprehensive, and state-of-the-art overview of various performance indicators and modeling techniques used for the evaluation and analysis of solar dryers, especially domestic and low cost solar dryers. Environmental analysis has severe global implications, and product quality is one of the biggest concerns of consumers. But the environmental impact and product quality assessments for domestic solar dryers are observed to be rarely reported in the literature. The use of modeling techniques in solar drying has changed the way of analyzing any thermal system. Here, an attempt is made to establish an overall assessment criterion for domestic solar dryers and to give a one-stop solution for researchers and users around the world.

“…Passive dryers are more economical and cheaper as reported by (Balasuadhakar, Fisseha, Atenafu, & Bino, 2016). Several studies classify solar dryers as direct, indirect, or mixed mode, and divide them into three types: cabinet (box), greenhouse, and tent, which come in a variety of sizes, shapes, and designs, as described by (Ekka, Muthukumar, Bala, Kanaujiya, & Pakshirajan, 2021). The air movement, mode of heat transfer, and design are the most typical approaches for solar dryers, as discussed in (Bhardwaj, Kumar, Kumar, Goel, & Chauhan, 2021;Chavan, Vitankar, Mujumdar, & Thorat, 2021).…”

Solar energy is becoming increasingly important as an alternative energy source due to the demand for new energy and environmental concerns about reducing greenhouse gasses. Food scarcity and agricultural product loss are currently affecting the world as a result of poor drying and storage methods, which result in post-harvest losses. The developed passive mixed-mode solar dryer was tested at daytime, from 9:00 to 18:30 hours. The study focuses on the thermal evaluation of the passive mixed mode solar dryers using experimental methodologies. The solar dryer achieved a maximum air-drying temperature of 69.2°C while the flat plate solar collector achieved 68.8°C respectively. The average air-drying temperature was 50.1°C, while an ambient average temperature was 29°C. This research demonstrates that a passive mixed mode solar dryer can effectively dry food and benefiting the community.
