vic, Check out the food preps board here on the forum. There are more threads on dehydrating food than you can shake a stick at... from comparisons on different types of dehydrators (maybe on the gear board), to links to YouTube how-to videos, to successes and failures of various members... it's all here. You can definitely dry your own food, preferably from your own garden, learn how to store it properly for longest life, and then learn how to use it when you are ready all here on the forum...
Good luck, and welcome.
