Abstract

This analysis investigates the widespread use of solar drying methods and designs in developing countries, particularly for agricultural products like fruits, vegetables, and bee pollen. Traditional techniques like hot air oven drying and open sun drying have drawbacks, including nutrient loss and exposure to harmful particles. Solar and thermal drying are viewed as sustainable solutions because they rely on renewable resources. The article highlights the advantages of solar drying, including waste reduction, increased productivity, and improved pricing. It is also cost-effective and energy-efficient. The review study provides an overview of different solar drying systems and technologies used in poor nations, aiming to identify the most effective and efficient designs. The focus is on comparing current models of solar dryers for optimal performance. The review underscores the importance of solar drying as a long-term, eco-friendly approach to drying food in developing countries. This review aims to evaluate how using solar-powered drying techniques can enhance food preservation, minimize waste, and enhance the quality and marketability of agricultural goods. The paper will specifically focus on examining the efficacy of these methods for drying bee pollen and pinpointing where enhancements can be made in their advancement.
