A kitchen gadget that consists of a small heater, a blower and clear plastic trays that stack together, with a plastic lid that has an adjustable vent on it.

The food dehydrator can be used to dry fruits, vegetables, meats (think beef jerky), basically anything you want. You can make your own trail snacks, fruit leathers, soup mix, etc.

I actually make a mean tofu jerky with ours.

Since there's actually a bit of heat involved, the food dehydrator slow cooks the food as it's drying it. So you can put raw meat in it and it will be cooked and dehydrated.
