Converting a corny into a conical?

Yeah I've used them in the past with no problems. Basic Brewing just did a show on them with Chris Colby. Check it!

Thanks for the info Rhino!

Cancel this one guys, seems the vertical pressure of even a 5 gallon system is enough to stress the yeast and increase ester production. Oh well, sounded fun. Looks like I'll just be going with a Toledo Metal's hopper & a pressure clamp lid setup instead.

That doesn't make a whole lotta sense seeing as how breweries routinely have 30 foot high fermenters. Pressure on the liquid under 30 feet of wort is definitely considerably more than that under 3 feet of it....

Just sayin.

Completely and absolutely agree. There is no way in hell that the increased dissolved CO2 at the bottom of a corny compared to the bottom of a carboy or bucket is going to make any noticeable difference. When you are working with 30+ bbls, I can see the differences being more noticeable. On the homebrew level, I just don't buy it.

What about this --

you take a sheet of nice food grade plastic, say PET. You cut out of it a shape that can be rolled up into a cone with a little gap at the bottom and a top diameter (big end up) that is equal to the inside diameter of a corny keg. All worked out so you have a cone with sides 30° from the vertical.

It gets stuffed into the corny (flexible so it fits and pops back out into shape) effectively giving it a "conical" bottom and the diptube is fitted so it runs inside the cone.

You ferment your beer and the vast majority of the action happens "inside" the cone, with the yeast settling to the bottom in the same way as a regular conical. When you want to rack off the yeast/trub, you attach a LO qd, apply some gas pressure and push the goop up the diptube and out. No dry hopping with flowers obviously.

And then the beer is basically in a secondary/bright tank - your own private unitank, allowing you to serve directly from your primary fermenting vessel.

To get a "full" kegs worth of beer.. consider the notion of combining the Thirstyboy patented "Corn-ical" with a burton union (like the one in BYO) that would allow you to fill it all the way to the top and not worry about blowoff or headspace. This would work with or without the corn-ical idea.

Combine them or not at your leisure.

Its an idea anyway

Here's a fantastic program to lay out your 3D cone onto 2D material:

I used it to make expansion pipes. There's a bunch of functionality you may not need like skew, but it defaults to the easiest settings, which is probably what you need. And you can print it out on paper and transfer from the paper.

It's free to use for a week or two....
