A few pictures of the solar dehydrator I put together this summer. I didn't get around to experimenting with it too much this season, time got away from me.
I think I'll have to work with an electric dehydrator over the winter, and come back to this again when it warms up again next year.
The basic design has three chambers: the front chamber has the glass allowing light into the area that is painted black (with some layers of metal lath that is painted black as well) to transform solar light into heat, and set up a warm passive air current.
That air rises in the area below the glass, and then falls through the screen-trays, to hold the thin slices of food. The back section then has a chimney area, where the air is pushed out a screened area at the back of the unit.
I'm hoping to make some dehydrated fruit pieces for snacks, some dehydrated vegetables for soups, and maybe some dehydrated meat for jerky.
