i've been using a hop screen. it's like a hop spider but had a top that screws on and the whole thing goes into the wort. I have a copper wire attached to the top that i use to pull it out to add hops during the boil.
when i add the flavor hops at 20 min, i pull it out, drop in the immersion chiller to sanitize and add the screen back in.
for the flame out, i pull the screen, add hops and place the screen back into the wort, in the middle of the chiller.
i found that stirring the wort with the chiller is more effective than using a paddle to stir the wort inside the chiller.
once the wort is a little below pitching temp, i pull the screen and chiller.
i stir well to get a whirlpool going and let it sit for 20 minutes.
i notice a bit of hop material in a tight pile in the center of the kettle.
the hot/cold break remains in suspension and drops over the 20 minutes.
it seems to settle evenly across the bottom.
i started using the screen to get clearer wort into the fermenter.
i think maybe the hops helps the hot/cold break stick to the cone.
i'm going to go back to letting the hop pellets roam free and see if the cone improves at all.
