What You Need to Know
Solar dryer dehydration involves water evaporation using solar energy, typically occurring at ambient temperatures between 30-40°C over 24-48 hours. This method is effective in regions with high solar radiation, common in Africa. The process prevents spoilage and extends shelf life by removing moisture from food.
