I think Zoom Zoom is the resident expert on dehydrators, but I expect he'll say 'yes'.
I love mine. I've been thinking how to dehydrate 'bigger' things as well. My theory is that all the work is done by the 'lid', and I was going to just build a larger box, with a cutout on top to fit the lid (or, perhaps just use one of those clear plastic storage containers, and cut a hole in the lid to fit the top of the dehydrator?). Cut some holes in the bottom to allow the air to flow out, and I think it would basically work the same way? I have a couple of airplanes that won't fit in the round chamber, so this is what I was planning to do for those.
Perhaps I'm missing something. Surely someone will tune-me-in if I am...
