I finally decided to install an in line thermometer on the exit of my shirron wort chiller to monitor wort temps during my chilling process. I have used a shirron plate chiller for years with fairly good success but have always had temps in the high 70s and 80s at the end and had to wait or place the fermenter in an ice bath to get the final temp drop to mid 60s. Part of this is the ground water temp I use to chill (mid-upper 60s) but I was hoping that adding a thermometer to the line and a ball valve to control flow that I may optimize it further. So this whole thing is screwed together on a SS t-piece. PLumbers tape used to stop leaks. It has quick disconnects to take it off and on the chiller. My question is what is the best way to sanitize this rig? Taking it apart, re-taping everything, etc is going to be a bear. Is running hot wort thru the chiller and the rest of the tubing for 5-10min sufficient (running it back to the kettle and then when ready to chill directing it to the fermentor as I turn on chill water)? Should/Can I submerge the entire thing in Starsan? Can brewing thermometers be submerged (essentially came from a weldless setup for a kettle thermometer I had lying around)?
MOREBEER sells these rigs already pieced together (I just had the parts left around from prior projects) so I know people use it, just looking for good advice on sanitation. Thanks
