Not a hops grower (yet?) but I can say you'll have a time drying even a dry pound of hops in a food dehydrator.
I know of a good rig used for drying mushrooms that I was thinking I might try for this when the time comes:
Take a stack of home air filters (cheap kind), layering your mushrooms (hops) in between. Attach to a standard box fan, ideally with bungee cord. Run until "cracker dry", usually 1-2 days (mushrooms lose ~90% weight, hops guessing probably 2/3 that much? 3/4?).
I'm sure there are already threads here about drying hops, but that would be my preferred low-temp way to dry pounds of anything.
