hi all, im trying to undestand why beer fermenters have a dome shapped top, i believe that its for pressure distribution for isobaric fermenter but, for non isobaric fermenters its there any use on that or its just that they look good.
the main reason its because i want to make me a 10bbl fermenter, i got all the equipment uncludinf the shop for sanitary welding (not mine but a friend of mine), so i can make it conical with out problems but the dome top its quite hard to make, im trying to make it simple, flat top with a big 12 inch ferrule on top and a 4 inch reduction ferrule for the arm and the spray ball, main use would be mead and wine.
so the main question its does a flat top could be a problem?, should be ok to add a manhole in the middel of the tank?
