How to Solar Dehydration

What You Need to Know

Solar dehydration uses heat transfer to evaporate water from food, typically between 50°C to 60°C, and can take 6-12 hours depending on humidity, temperature, and food type. This method relies on the principles of thermodynamics and mass transfer to preserve food.
