While I don't know of any site that has plans, I remember the one a

In the lower half he placed a space heater facing the opposite side
and a piece of sheet metal wedged into a curve to deflect the heat
upwards. The top was open. The screened shelves were boxed in making
it more a "drying tunnel' than a dehydration box. It did the trick
Sorry I don't have more precise measurements. But I remember this
from the 6th grade and I'm 45 now.
That's interesting, the one I've used for years used a ceramic cone shaped

such as you would see in an elect dryer coiled arround the outside. It has a
screw base at the bottom of the cone just like a regular light bulb. RM~
As JOAT would say if he were still posting, "google is your friend."
A google search on "ceramic screw base heating element" (without the
quotes) turned up a number of hits.
