What's the best way of inducing a whirlpool vortex when using an immersion coil chiller?

I suppose if I'm doing a hop stand for 30 min, I'd do that first, then insert the chiller and start cooling after then required 30 minutes. But -- if I want the hop stand at, say, 180F, I need to chill it from boiling first. Okay, insert chiller, cool to 180F, remove chiller, start whirlpool + hop stand, wait 30 min, re-insert coil, cool the rest of the way?

How can I sanitize the chiller coil the second time -- since it usually needs to be at boiling for ~20 min? Star-San?

On a related note -- when I'm chilling, I usually swirl the coil around in the cooling wort to increase contact, and cool things faster. But it's occurred to me that I'm interfering with the hot break -- and just mixing everything up. Is there a better way to do this?

Thanks!

I'm fairly new to all this but I see no reason to re-sanitize the chiller as long as you don't set it on anything that would contaminate it. If it was sanitized going in, or by sitting in the boil for 20 min, and you don't put it on anything dirty there is no way it should contaminate your beer.

Alternatively if you are concerned then put it back in and literally give it a minute it should kill anything it got from the air. 180 is a safe temp

I leave my IC in during the 180F hopstand/steep (and I cover with aluminum or plastic wrap too to keep the dust and flies out )... and I periodically stir it up because I leave my spoon in there also.

I float my pot in my swimming pool to chill to 180, then hop stand.

Drops to 180 in about 1 minute (current water temp is 50 though)
I do the same in the summer with 90 degree water, takes like 2-3 minutes to get to 180.

Without the swimming pool, one could use a tub of water in the same way.

I sanitize my IC in a tub of Idophor solution during the hop stand.

Sorry if I am missing something obvious, but why are you taking your chiller out?

I understand it is important to maintain some heat during the stand.
Covered and insulated does that.
Covered is going to keep the nasty's out too.

Umm, okay. Not sure what that had to do with my question, but that's spiffy, I guess.

hard to put the lid on tight, unless you're IC fits entirely under the lid.

Ahh! The penny drops! I follow you now. It didn't occur to me because when I used an immersion chiller I notched the lid so it would stay on during chilling.

Sorry for being a thickie.

Actually, I was assuming I'd remove the chiller in order to start a whirlpool effect. There's no way I could do so with my chiller and my BK.

Of course, it doesn't seem that a "hop stand" requires doing a whirlpool, but the canonical BYO article associates the two pretty closely.
