As part of my brewhouse build I am updating my brewery as well. I am starting out converting to electric, then slowly convert to (the dream) fully automated including transfer to fermenter and fermenter control. I am working on rough plumbing diagrams right now while I get the stand welded and the basics on order (brewtroller dx1 module, enclosure, elements, ssr's, etc.)
First draft on plumbing:
Basic 60A eHERMS keggle system, blackheartish... , 2 pumps, CFC output. Plumbed to water inlet, CFC flows into septic line. Batch sparge, recirculate boil to sterilize CFC, probably will not recirculate HLT since I would believe convection in a keggle would maintain homogenous temperatures in that small an area, but am prepared to redesign if experience tells me I am wrong. I would like water inlet to all 3 kettles so I could potentially program a "clean cycle" type recipie. MLT *may* end up direct fired NG if i can get a plumber to extend my line a few feet for a decent price, or I can add a 3rd element on 60A service and just make sure only 2 are ever on at the same time.
With those familliar with brewtroller workings, I am wanting to possibly extend it with a RGBIO8 module to help control a cold room/fermentation as well, but that is down the road.
If there are any problems with my plumbing, I would love the feedback, or any clarification/problems with my dreams.... Just let me down slowly
