Can I remove my spundIT 2.0 when I go to cold crash? Does it matter? Or should I keep it on?
I usually just leave it on but I do add some C02 before cold crashing and remove blow off tube so I do not suck in any air or sanitizer with the negative pressure that occurs.
I misunderstood your use of the spunding valve. If your actually using the valve for spunding then correct no need for blow off (I attach my blow off tube to spunding valve initially and keep 3-5psi during fermentation -non spunding). If I want to spund then no need for blow off tube. I just set to the pressure I want toward the later stage of fermentation and let it build up CO2. Pressure will drop with cold crash as you said but you will still probably have some positive pressure in your fermenter (If you leave the spunding valve on you will know). I guess you could release the pressure to allow adding the gelatin if you have a way to do this without exposing to oxygen.
What are you fermenting in?
I've not removed a spunding valve from any fermenters using one before chilling the batch down. I've also had Starsan solution between the spunding valve and outside air. Never had any suck-back. Then again, that's been with either the Blowtie or the TC spunding valve from SS Brew Tech. If your spunding valve isn't able to prevent suck-back, then remove it. IMO, any quality ones WILL prevent suck-back.
Before I switched to conical fermenters (yeah, NOT cheap) I was using two Blowtie units (both generations). I liked the newer generation better. Still have them right now but might get them to some new owners.
IMO, as long as the batch is completely done fermenting, you can remove it. At that point, you have a closed system so it won't matter. Also, corny kegs are rated for over 100psi, so you really don't have anything to worry about for pressure level buildup in the keg.
I've never used gelatin in any of my beers. Never needed to. I give them enough time for the yeast to settle and then either do a pressure/closed transfer, leaving the yeast behind (from the kegmenters) or dump the yeast before finishing/carbonating the batch (conical). For the conicals, I give the batch another 2+ days to settle once the CO2 is disconnected to settle again. Very clear beer is had by all.
