DIY solar food dehydrator. Like this design, as I read that foods dried in sunlight were much more nutritious than foods dried in the dark.
How To Build a Solar Food Dehydrator Food dehydration is not a new concept. From raisins to prunes to jerky, food has been dried for storage and later consumption for years. Solar dehydration simply refers to using the sun’s energy to complete that process. If built correctly, a solar dehydrator will not need any electricity and will be able to dry foods in even the most humid climates.
