“…Comparison of various tomato dryers in drying time and final moisture content (% wb) is displayed in Figure 14. Conventional hot air blower tomato drying conducted by Mariem and Mabrouk (2014) reduced moisture content of tomato to 11% in 9.9 h. Abuelnuor et al (2021) performed experimental study on tomato drying using indirect and mixed mode solar dryer. The final moisture content of 10.4% was achieved during 10 and 9 h, respectively.…”

An indirect type domestic hybrid solar dryer (ITDHSD) has been fabricated and its thermal performance, exergy, and drying kinetics of tomatoes slice were analyzed. Moisture in tomato slices was dried from 95% to 9% (wet basis) in 10 h of solar drying in ITDHSD during the winter season. Drying curve obtained was fitted with different existing empirical models and Prakash and Kumar model was found suitable for tomatoes drying in ITDHSD. Overall drying efficiency of the system was estimated as 41.05%. Furthermore, with variable mass flow rate, exergy efficiency values varied from 32.86% to 58.26%. Overall exergy efficiency was 46% during tomato drying experimentation. Various exergy sustainability indicators have been estimated in this study to observe improvement potential in the system. Improvement potential, waste exergy ratio, and sustainability index of the ITDHSD system was estimated in the range of 0.006966–0.065984, 0.41–0.67, and 1.55–2.39, respectively. Therefore, ITDHSD system provides a better option to domestic users for drying food crops in less duration and with no deterioration. This piece of work will be helpful for researchers in performing exergy analysis, drying kinetics, and performance assessment on hybrid solar dryers. Novelty impact statement All available literature on tomato drying in a compact sized dryer lacked in evaluation of the exergy analysis of solar PV module used to run a fan. Moreover, an essential factor of equivalent moisture content is also neglected in the literature during calculation of moisture ratio, which cannot be neglected in drying high moisture crops in tropical areas with high relative humidity. In the present experimental study, a new hybrid solar dryer system design has been developed and fabricated for domestic users.

“…Mugi and Chandramohan (2021) performed exergy analysis on an indirect type solar dryer. Abuelnuor et al (2021) fabricated a solar dryer and dried tomato under indirect mode. It was reported that tomato slices were dried within 10 h. Ramirez et al (2020) analyzed an indirect solar dryer with and without PCM.…”

“…El sistema de secado consiste en eliminar la humedad que contiene el producto y así evitar que se deteriore [9]. Estos sistemas pueden usarse por ejemplo en el secado de tomates usando un sistema fotovoltaico como se presenta en [20] y se pueden usar en el secado de pescados como se presenta en [21]. En general, un sistema solar de secado proporciona un proceso limpio que puede aumentar la eficiencia energética y minimizar el consumo eléctrico.…”

The agriculture and food industry is very important for human society development and is constantly growing with the world's population. Agriculture is also among the activities that generate a lot of greenhouse gases, therefore there is a need to opt for the implementation of renewable energy resources for processing. Solar energy is a good solution because it is clean, natural and abundant as well as usually being available in the regions used for growing food. This paper presents some processes in the agriculture and food industries in which solar energy systems can be used. The state of the art and practical examples of the incorporation and adaptability of solar energy are also presented.
