I own an American Harvest dehydrator and this gadget was so useful when I needed to dry a ton of peppers from my garden.  If I could not use them all fresh I dried the extras.  I made my own chili powder,  paprika and then left them whole for different recipes.

The peppers below I use to make my recipe Arbor Chile Peppers Chicken.

One thing I do recommend is you put this gadget in your garage as the smell from the peppers drying is quite strong and not an odor you want in your house.

Of course the dehydrator can be used to dry anything such as fruit rings, beef jerky or even fruit rolls.  The drying times vary with the humidity and the thickness of the food and also the number of trays you are using.  A cookbook and instructions are included for drying all kinds of things.
