Default How To Make A 15 Gallon Fermenter

first i started with getting the keg top cut out. since i had an 8" flange, i had the hole in the keg cut appropriately. i then had the flange welded on to the keg top. (I'm neither a cutter nor a welder so i had to out source these procedures)

what we're looking for here is a smooth, sanitary weld.

i cut the lexan circle to fit the top of the flange lip. the lid was then drilled, and tapped to fit my compression fillings.

the gasket material i fashioned from a piece of latex tubing. i rolled the tubing back on itself, and snapped it over the other end.

finished keg

during fermentation one of the ports will be capped off while the other will be the blow off tube. when primary fermentation is complete all you need to do is insert a tube into the portal, pressurize the keg through the other portal with co3, and extract the yeast from the bottom of the keg. now you're ready for secondary clarification.
after clarification is complete you pressurize4 the keg using similar technique as above and push the beer into kegs for carbonation.

many thanks to TC, SWL, and Brewgeek for their help. without them i'd still just have an idea.

Well that's a one off design.
Cool.
Where did you get the 8" flange?


What boil kettle are you using for 15 gallon batches?

8" flange was a freebie from a member of our brew club who does polimars and high end chemicals.

i'm using a 20 gallon boil kettle to do 15 gallon batches on this:



we also have a club 50 gallon kettle and fermenter



we'll be using this one to do our 55 gallon bourbon barrel brew this fall that will condition in cold storage until next fall

I'm assuming all the work putting the flange on was to acheive more headspace right? I was going to make a lexan cover and put it directly down on the top of the keg, but that would limit me to 12 gallons or less.

that would absolutely work bobby - in fact that was my original idea - but then i happened upon the flange - and i thought - BAM ! more head space - more beer YEAH!

Brewhead, can you tell me how that lexan was cut? I actually need to cut a circle out of some 1/4" lexan myself, and was really wondering how to go about it without getting a nasty lop-sided mess.

Thanks in advance!

BTW the fermenter looks great!

i cut the lexan with a craftsman scroll saw and smoothed it all out with the belt sander. the thinner the blade the better the cut will go. it will take you prob 15 minutes or so of cutting if you are patient. push it and you'll be breaking blades

I hate to rain on anyone's parade or efforts, but I don't think the Lexan is going to stand up to much pressure before it breaks or cracks.

An 8 inch hole has an area of 8^2*pi/4 = 50 in^2. Applying 3 psi to the vessel will result in a 150 pound force to the lexan. I guess it depends on the thickness of the lexan.

Otherwise it looks great.
