question on whirlpool rest and techniques

[HOPSareKEY]

Hello,
I moved to an upgraded single tier system and my boil kettle has the ability of whirlpooling. I thought I understood the process from an article I read, but now I can't find that article any longer and all methods I'm reading are different.

Everything says to whirlpool for 20 min after the boil. To me, that kind of throws scheduling off and I want my wort to chill as soon as possible after boil.

If I do a 60 minute boil, can I start the whirlpool at 20 min left?

Will the vigorous boil counter the whirlpool?

What is the best way to go about this?

Thank you.

You whirlpool
- because you can
- 15 min or so before flameout to sanitize the whirlpool / run-off circuit
- to immersion-chill much faster than if you're wort weren't moving
- in order to collect solids in the center of your pot
- in order to extract late hop flavors between 155-185

Start the whirlpool 15 min before flamout just to sanitize your pump, lines, etc.

If immersion chilling, whirlpool against the immersion chiller and your temp will drop insanely fast.

If trying to collect solids in the center, flame out. The solids -- even fine ones -- will follow pressure gradients to the center, but actively boiling or other agitation will foul this.

If trying to hop-burst, whirlpool is the best.
