This study evaluates a greenhouse-type solar dryer with adobe walls, a natural material known for its thermal inertia, aimed at improving the drying of agricultural products in tropical regions. By using local materials, the system reduces costs and environmental impact while enhancing energy efficiency. Experimental observations demonstrate the dryer’s ability to maintain stable internal temperatures above ambient levels, even during sunless periods, highlighting the thermal inertia of adobe. The findings confirm that adobe-based dryers provide a sustainable, low-cost alternative to conventional systems and support their broader adoption in rural areas. The results also suggest potential for further optimization and scaling using other natural materials.
