Flow-Control Dry Hop Frustration

I used to use a corny keg specifically for dry hopping.

It had a modified dip tube, picture a U shape at the bottom of dip tube. Would transfer beer from primary into the CO2 purged dry hop keg, lay it horizontal, rock it around once a day for a few days then stand it upright and cold crash.

Hops and yeast settle below dip tube pickup. Transfer it from the DH keg to CO2 purged serving keg via closed transfer.

 

What I'm trying to picture is the radius of the "U" that would make it effective and still allow installation of the diptube.

 

I'm picturing a removeable U that gets installed on the end of the dip tube after the tip is inside the keg.

 

To pickup beer from above slurry. I thought if I just cut the tube that there would be a vacuum effect that would pickup settled out hops and yeast slurry.

Also, yes @VikeMan !

I cut the dip tube about 2" up. Formed a U shape out of silicon tubing with same ID as the dip tube OD. To form shape I used stainless steel wiring wrapped around it like a candy cane then slid the tubing on the dip tube end when reassembling keg after cleaning.

It worked well and got really good hop:beer contact when I would rock/shake it up during dry hop.
