Default Closed System Brewing Kettle....Project

Call me overly paranoid, but I had an idea to create a complete closed system brewing system. It isn’t quite done, but this is the first step. Here is how I envision it working.

1. With about 15min left in the boil prop the lid on the edge of the kettle with the cooling coils in the boil.
2. With about 1min left seal the lid down. I still need to build a clamp that goes through the keg handles, put a silicone seal around the lid’s perimeter, and install a HEPA filter in the lid to allow the kettle to breath.
3. Start my pump and the cooling coil to create Jamil’s whirlpool immersion chiller.
4. After cooled I can let the trub settle for a long time and not worry about contamination as the kettle is sealed.
5. In the meantime I will fill a carboy with sanitizer and drain it with MoreBeer’s Sterile Siphon Starter.
6. Finally I will connect my kettle to the Sterile Siphon Starter to fill my fermentor.

Now I just need to figure out how to aerate and pitch the yeast.

+1 on you being paranoid. I know we all build some crazy systems, but a sealed kettle with a HEPA filter? This just seems like too, too much!

slight overkill....fun idea though. Why are you so paranoid though? have you had contaminated batches or what?

Ouch. No bad contamination issues, but I did get sick of covering my kettle with foil while cooling. It is very windy in central Montana and I don't like dirt blowing into my cooled wort. At first I was just going to mount my chiller into the lid so I wouldn't have to waste foil, then I figured why the hell not take it to the extreme. Heck with this system I would feel comfortable leaving the wort overnight if my yeast starter wasn't ready or if it was a late brew and I wanted sleep. But my main reason is ... because I wanted to see if I could.

Its a cool idea I really like your lid I think I might make something like it to hold my chiller in place. I dont like the idea of puting a lid on a kettle untill flame out so I might make mine w/ a hinge and hinge 1/2 of it so I can keep it open untill flamout. I will have to work on some sort of a O2 injection system
Cheers
JJ

I lived in Kalispell and Whitefish for a while so i know where your coming from. Personally i have a sanatized carboy handy and i pour the wort in semi hot and let it cool with foil over that. I never had a problem leaving that overnight. Its a cool project- i didint mean to seem condescending however its alot of money for copper and supplies when its something you could do with foil. Good luck

Already had the lid and cooling coil so no extra expense. No worries. I just built a trebuchet out of 100% duct tape to see if I could, so I am used to people thinking my ideas are a bit off . By the way, I just left Kalispell. Worked for Semitool for 7 years. I sure miss that area.

what are the little white keepers you put your copper tubing through? Where did you get them?

They are pieces of plastic that I machined to fit tightly around the copper pipe.
