Growing a year's worth of food brings up many questions, but the most critical one is how do we preserve the bounty of our garden?  Of methods that I know of, one can dry, ferment, can, or use cold storage.

After researching different design ideas, I went with a design that I could use some recycled materials and materials left over from other projects, plus some new. I also wanted a high-capacity design that could dry a lot of food at once. This design has a heat collector and a tower. » Read more
