I stumbled across something like this
on eBay when looking for a cheap inline exhaust fan. It's incredible how much we home brewers have in common with hydroponic and indoor gardeners
when it comes to equipment. I'm pretty sure I know what this was designed to dry, but I'm also pretty sure it would make a heck of a hops dryer - especially if you pointed a fan at it to increase air flow. What I like best is that it's collapsible so it will hardly take up any room the 11 months out of the year when I don't have a use for it. So much better than the DIY oast I was planning to make. I don't know if anyone out there is already using these for hops, but I thought I would share.
