Why didn't I think of this? Not sure how well it would work, but I dried some in a toaster oven that came out OK. Theoretically, I would guess this should work even better going low and slow to avoid splitting. When I was looking for ways to dry some Holly (and decided on the easy toaster oven method), I saw nothing about this that I can recall. Give it a shot and let the IAP community know how it works.
I use one and it works great. Just keep track of the weight of your items. When the weight does not lower any more it's dry enough to turn!!! It does take some time - depending on where you start on moisture content - i.e. 24-36 hours has been typical.
To the best of my knowledge wood should have zero moisture content. A food dehydrator may not get quite that low but you could finish off the drying in a toaster oven. You'll need it to heat cure the juice anyway.
