Assessing the feasibility of solar drying for fruits and vegetables in El Hodna region, M'sila, Algeria

This study investigates the feasibility of solar drying of fruits and vegetables in El Hodna region, M'Sila, Algeria, by examining key climatic factors such as solar radiation, air temperature, humidity, and air velocity. Solar drying is a sustainable food preservation method that leverages solar energy to remove moisture from agricultural products. El Hodna region, characterized by abundant sunlight, high temperatures, and favorable air velocity, presents an ideal setting for this technique. By conducting a comprehensive analysis of climatic data, this study aims to ascertain the region's suitability for efficient solar drying. Climatic data, including solar radiation levels, air temperature, humidity, and air velocity, were collected from meteorological sources. The analysis revealed that the region receives high levels of solar radiation, averaging 6.5 kWh/m²/day, and experiences air temperatures ranging from 25 to 35°C, which are conducive to drying. Additionally, the relative humidity, averaging around 40%, facilitates effective moisture removal, while air velocity, typically between 2 to 4 m/s, helps accelerate the drying process by enhancing moisture evaporation. These findings indicate that the climatic conditions in El Hodna are highly favorable for solar drying. The study concludes that solar drying is a practical and viable method for preserving fruits and vegetables in El Hodna, M'Sila. Implementing this technique can significantly reduce post-harvest losses, enhance food security, and promote sustainable agricultural practices. The potential benefits extend to local farmers, providing them with a cost-effective and eco-friendly preservation method that leverages the region’s natural climatic advantages.
