My microbulator 50 would have used a cone bottom tank except for the fact that I was trying to develop an affordable brewer to ship and that could be used with a standard size 55 gallon barrel. There is a 1000 gallon brewer using a cone bottom tank which I designed a couple of years ago operating on a 1200 acre Texas farm.
There are actually quite a number of cone bottom tanks being used for brewers on the market. I believe heady blunts(?) posted a link to one in the thread where he talked about his brewer.
Anybody can be wrong about anything.
