I just lay them out on an old windowscreen in my basement for 4-5 days. I figure a few days before I get them in the freezer (or beer) isn't going to be too harmful.
I thought the same about heat.
I built an oast with just fans and no heat. They dried in about two or three days easily and have fresh smell. It's not a hard project if you have the tools, time, and some basic skills. I happened to have some old PC type 120mm fans lying around too. I made it completely from scratch without any plan and used pine boards, luan ply, chop saw, table saw, wood glue, 16 gauge pin gun, staple gun, and some fiberglass screen. Took me half a day. I have four layers and can make more if needed for next year. My garage smelled pretty dank for a few days.
