I also tried an antique sheet-metal wet-heat corn dryer designed for wood-stove-top use, but its single, rusty-hardware cloth tray left barbecue-marks on the apple slices. Plus, it was too small to keep up with our kids' hearty appetite for dried delicacies. In the 1970s I gave in to progress and got one of the MacManniman's big yard-square electric food dryers.

To build your sun-powered unit, choose a long, shallow cardboard box and cut a few holes in each of the narrow ends.
That done, paint the inside of the container black or line it with black plastic sheeting — whichever is easier. Cover the box with clear plastic, and your heat catcher is complete.

We built this solar food dryer because all of our harvests seem to come at the same time and we needed a way to perserve our food and seeds for later use. We must dry out seeds from our best fruits and vegetables to save for the next planting and it is hard to do that in our humid rain forest environment. But, we have the benefit of being close to the equator, 10 degrees above it to be exact, so the suns heat is very strong. We had tried other types of dryers but the jungle mice, birds and bugs always seemed to find a way to eat everything we put in them. The door on this dryer is heavy enough to keep out the more crafty thieves and has just enough of a seal to keep out the bugs, while screened in vents help to promote air-flow.
