The project addresses the limitations of traditional open sundry techniques widely used across rural areas of Lao PDR and neighboring countries. While these methods remain popular due to their low cost and simplicity, they result in significant product losses and quality degradation from environmental contamination (dirt, insects, animals), unpredictable weather conditions, and inconsistent drying temperatures. Solar dryers, utilizing scientific principles, offer a superior alternative by providing controlled environments that protect products from contamination while delivering more consistent results.
