It depends on what yeast you’re using when it comes to soft crashing. Some will take their time, other’s won’t. It’s something you just need to pay attention to and maybe try different times and temperatures.
I’m sure just about everyone is using some sort of 1318 variant. It floccs pretty well. After ferment is done you can just set your temp to 55. Depending on how you’re cooling 24 hours is really all you need. Harvest yeast (reuse it, don’t dump it) and add hops. There’s plenty of info now that says 24 hours is all you need. Extraction happens really fast. Pretty sure the brewery that won alpha king and GABF for hazy double ipa last year removes hops after 24 hours. (Burke Gilman). You can leave for longer if you want or add another dose of hops. Now start crashing and wait maybe 48 and slowly dump again... then leave at 35-38 for a bit to condition then transfer.
The 2” dump valves on the spike fermenters are dumb. 400bbl fermenters only have 1.5” valves. If you can add pressure, there’s zero reason for 2”. I remove everything below the cone and just put a butterfly valve right at the bottom. No elbow, so sight glass, nothing. The whole surface to volume ratio made zero sense to be when there’s a 2” port on a 7g fermenter. Started when I was making lagers in them then just kept doing it for hoppy beers. In both cases you’ll want what’s siting in those 2” valves in contact with your beer.
Anyways there’s no reason to resuspend in my opinion but you want want to try ditching everything below the cone, especially if you’re going sightglass then elbow.
