Project Goals[edit | edit source]
The goals of this project are to dry fruit in a sustainable manner using appropriate technology.
Design[edit | edit source]
My design is a three layer system. The base has corrugated tin roofing for ventilation, the second layer is the drying screen where the fruit or vegetable is layed, and the top layer is black, double paned glass for attracting and retaining the heat.
