Dehydrating Instructions For Vegetables

Bacon and Eggs

I found a good starting place for those of you who want to learn to dehydrate veggies.  Please note that dehydrators and methods for dehydrating vary. Vegetables may be dehydrated at temperatures starting at 100 degrees ranging up to 140 degrees. The higher the temperature the shorter the dehydration time. Also, with higher temperatures it is possible to cause case hardening of the vegetable. Case hardening occurs when the exterior of the vegetable dries too rapidly creating a seal that retains moisture in the center. When this occurs the food will spoil from the inside out.

        The best thing is to get on Youtube and search Solar Food Dehydrator and you will get 100’s of videos of all different shapes, sizes, and designs that people have come up with. Then when you see all of them you will get a pretty good Idea of what they consist of. I am keeping my eyes open for racks that would work, and them just build the box to fit the racks. If I don’t find any pretty soon I will just make some racks. I am thinking that the plastic racks that nurseries use to carry their 2-4 in. starter plants in might work. I need to go look at some, or something like them.

        I hope that helps. I am also looking into making a Vacuum Canister to make freeze dried food. That gets a little more technical, but don’t look to hard. A making log splitter is what I am looking for parts the most right now. Not working a job right now, I keep looking for things to build to cut our survival cost down every chance I get. Like my first veggie garden I just planted 3 weeks ago. haha
