The purpose of this research is to determine the best way to dry ivy gourd (Coccinia grandis) using a mixed-mode solar drier and to evaluate its efficiency in active and passive modes of operation. Effective drying techniques are required to extend the shelf life and maintain nutritional value of ivy gourd, a vegetable with a high perishability. Because it uses a combination of active and passive heating methods, the mixed-mode solar dryer can adapt to a wide range of climates. This study sounds fascinating! By investigating the drying parameters of Ivy Gourd and evaluating the performance of a Mixed Mode Solar Dryer, the researchers are addressing crucial aspects of post-harvest handling and preservation of agricultural produce. Understanding how factors like temperature, relative humidity, and air velocity impact drying time and product quality can lead to significant improvements in the efficiency and effectiveness of drying processes. Temperature, airflow rate, and drying duration were some of the variables tested in this study's drying trials. Product quality parameters such as colour, texture, and rehydration capability were used to assess the dryer's performance, in addition to drying kinetics and drying efficiency. We learned more about the relative merits of active and passive modes of operation in relation to drying uniformity and energy usage via this comparison. In active mode, the results show that the mixed-mode solar dryer performs better than in passive mode, with quicker drying rates and greater efficiency. We also found the best drying conditions to get the desired quality with the least amount of energy. The drying removal rate has finally reached 25%, and the efficiency has been achieved at 73.9%.
