Solar fruit dryer

Final shape of the solar fruit dryer designed in July 2008 at Malava.

It started with a sketch of a solar dryer in a book about renewable energy technologies. Prof. H. Othieno from OSIENALA designed this equipment for drying omena fish at Victoria lake region. There are many kinds of solar dryers but I decided to build this one mainly for drying fruits in order to preserve harvest.

The carpenter Michael with his employees made this wooden skelet of the dryer.
