I was searching the paleo archives for information about dehydrators, and I didn't come up with much. Perhaps I wasn't searching right. Anyway, I recently purchased a dehydrator via mail order. It's made by Ronco. It has 5 round plastic trays. I expected it to have a fan, but it doesn't. After searching the net, I learned that the better quality ones have fans and thermostats. Does anyone have experience using one like this? Will this kind of dehydrator work, or did I waste my money? Basically, I want to make jerky, some dried fruits and vegetables. Thanks.
