I just used my new setup of a plate chiller and march pump on my first 10 gallon batch. The chiller is a duda diesel, I forgot the model # but it’s one of the larger ones on their site. It’s about the size of the Shirron but thicker. Anyway, it didn’t chill as quick as I thought because my source water is warm (Florida sucks for brewing!) and my prechiller of my old immersion chiller in a bucket melted all the ice I had in about 5 minutes! Anyways… on to my question:
Rather than pump directly into the fermentor, does anyone recirculate back into the kettle? I figure I could run the pump more wide open this way rather than at a trickle to come out at 80 degrees. This combined with a few extra bags of ice should help next time. What’s the most efficient way to use a plate chiller? Wide open or something slower? How about for the chill water?
