Yeah, looked at some gear on AliExpress (Alibaba) and purchased a fancy column there to put together a cheap system for testing distillate recipes at a bud's meadery (where his licensing covers ltd. spirit production), but I was also trying to replace my previous AG Blichmann set-up that I gifted to my S-I-L (what was I thinking?) so I can still make me some beers.
It's complicated... lol
Gonna go poke around there some more I guess. Found copper domes for the smaller units, just nothing for the 65 L. so far.
Also, haven't seen one of these IRL, but I take it that there's no hack for replacing the elements? Not a big deal at those prices I suppose, but I hate disposable.
I have some other options, including three commercial 25 gallon s/s pots that had been crab steamers. Each has eight 7/16" holes near the bottom that I had intended to have plug welded, but haven't found a competent welder who can or will do it right. My original thought was to go back to an all electric three pot set-up, but the mobility of the all-in-one is tough to beat for my newly intended use (plus I don't need anything that big). Meanwhile, I'm beerless, so gettin' antsy to just grab something and get back to brewing so I can drink while I cogitate on this further. Paralysis through analysis.
Just to add more confusion, a bud told me the other day about a small jacketed steam kettle left-over from a food processor auction for cheap, so too many variables to contemplate w/o a beer in hand.
