Abstract: This review provides an overview of Evacuated Tube Solar Dryers (ETSDs), focusing on their components, working principles, and performance characteristics. The discussion highlights the role of evacuated glass tubes in improving efficiency, the functioning of solar dryers, their application in indirect food drying, and the parameters influencing their thermal efficiency. The ETSDs represent a significant advancement in the field of solar thermal energy technologies. They harness solar radiation efficiently and convert it into useful heat energy with minimal losses. The integration of evacuated glass tubes into solar dryers enhances their thermal performance, making them suitable for high-temperature applications such as food drying, space heating, and industrial processes This review concludes with insights on their potential and limitations as a sustainable energy solution.
