Design and Development of Domestic Solar Dryer with Comparative Analysis of Nutritional Aspect of Dried Raisins

Solar dryer technology is simple and can be implemented by households small communities due to its simplicity. The suitable design of the absorber/collector very vital for any solar drying system as collector efficiency plays a key role in determining overall efficiency. To study practical applicability developed dryer, grapes were dried chamber designed comparison, open sunlight. Faster was noted unit. on nutritional aspects indicated that process retained major components like total sugars, proteins lipids raisins. comparison between raisins sun ones showed higher ash content 2.71% with 1.95% case quantity MUFA also affected varying practices 10.95% 7.12% respectively. technique affects bacterial load observed our current negligible growth compared ones.
