Help me invent a rotating dry hopper

[dyqik]

Just pump beer out of the liquid tube and back in through the gas tube. That'll circulate the beer over the hops (in the keg). Flush the system with CO2 before you start (and maybe lay the keg on its side so that there's no problems with the pump having to draw liquid up the height of the keg).

You can clean the system with beer line cleaner and starsan in exactly the way you already do for your beer lines.

ETA: Or you could use a second keg and a randall and pressure transfer from one keg to another.

Could do a combination of ideas. Make the internal basket (that holds the hops) and the bar that attached to the lid stationary. Then spin the keg itself. Removes the added problems of sealing a spinning drive shaft, now you just have a stationary shaft attached to a keg lid.

Or you could throw the hops and beer into the keg, purge and cover with CO2. Then strap the keg down into the bed of a truck then go 4 wheeling through a mud pit for a couple hours. Have some fun while you're turbo dry hopping:rockin:.

Crazy as all this sounds............I like the hot dog roller idea the best.

You already have the dip tube in there, which could be the basis, or foundation for your "agitator", if you will.

Devise some type of detachable "paddle", that was easily sanitize-able, that could be clipped on the dip tube.

You could sacrifice 1 corney keg lid,to be used amongst all your kegs.

Attach your hop basket to the lid..........Solid stainless rivets come to mind, ( 'cause I do sheet metal work!).

Prep and install them properly, and they will hold pressure, as they do it all day long , ( rivets), on an aircraft fuselage.

Build a rack with inline skate wheels top and bottom, that will cradle the corney, with a stop at each end so the keg won't "crawl" out of the cradle.
The "stops" could include a skateboard wheel.......(hmmmmm, 'cept for the "notches" on the handle end of the keg....)......WAIT!

Make the handle end higher on the rack, then only one "stop" idler would be needed.

Rig up a slow, friction drive setup, where the drive wheel bears on the keg body...........Windshield wiper motor comes to mind.

Load the keg, purge, lay it on the cradle, and turn it on.
