Just looking back at my last brew, trying to figure out where I can improve or where I lost efficiency. I always despised vorlaufing, but would do it because it's very necessary. I now have a chugger pump that can recirc the sweet wort for me. That being said, I have been reading that I may need to slow down the flow?
I normally open up the necessary valves, turn on the pump, and the hose leading to the top of the MT had one of those jet-sparge connections at the end. This prevents tunneling because it spreads out the returning sweet wort rather than just sending it straight down in a stream.
I used to have a ball valve on the pump outlet, but I took it off and just replaced it with a throughput connector. If I am spreading out the returning wort, and I don't have issues with any solids in the pump, is it ok to run the return at full speed? I don't see why not, but just curious. If this is OK, I may have just not vorlaufed for long enough. The wort was clear-ish... Not my best but not muddy looking either. At this point I'm looking at any possibility, besides the obvious human errors, to find places to improve.
