Hello schematix!
1: Are you talking about a fermenter that is basically horizontal to fit in a freezer like this? http://ep.yimg.com/ay/yhst-39276693957820/frigidaire-mfc25v7gw-chest-freezer-for-220-volts-2.gif
Good suggestion. Isn't anybody already making horizontal fermenters? All the big breweries have them...
2: Perhaps this can be combined with the sparging filter of my design? I'll look into this. What kind of filter are you now using?
1. Yes a freezer like that. It would need to be short and squat. A suitably sized vessel can be purchased already. The feature I am most interested in is the 1 atm pressure rating for pressurized fermentation, carbonation and pressurized racking. That's what i can't find in anything under 1 BBL.
2. Every filter i've tried ends up clogging so right now i don't use anything. Clogging is worst than nothing at all. Right now I use only a few oz of hops and don't recirculate to chill as much as i'd like. Not sure how your design would apply here but if you can explain, I would entertain the idea.
