A funny read, but excellent points to be taken from this!
This is on the "to do" list.
I'm thinking make it more like a cement mixer so I could support the top of the barrel with a second bearing as well as tip the dry grain out instead of scooping it out or whatever Butch does.

Rpm could probably be lowered and a jacuzzi tub timer installed so you could turn it on and walk away for 5 minutes or so, come back when it shuts off and dump the grain, refill, turn back on and continue whatever else your doing in the stillroom.


Dang, I love this idea...

I know this topic is a couple of months old, but I have been doing some bourbon mashed latel and I am wondering if your homemade centrifuge would work on 70 pounds of grains at a time. I have been using a mop wringer for the last 5 or 6 batches, it works better than wringing it out by hand but it is still a far amount of work. With the mop wringer it still takes about 45 minutes with this volume of grain. I am not quit ready to speed 1500-2000 for a small industrial centrifuge.

70lbs of wet grains, maybe. If you mean a batch that starts out with 70lbs of dry grain, that might be a bit much, once it doubles or triples in weight with water.

Back when I was using that, I think that the spun grains that would come out, would be enough to fill 1.5 5gal buckets, and I would've been comfortable using more. 30-50% more even. Maybe you can use that to do some calculations.

I can't remember the dry weight of the grains I'd use in that recipe. It may be in another of my threads, even at the beginning of this one.

Either way, it did work great and regardless of the size of your mash, you could run 1/2 at a time.

Just remember, using a previously used washer is just about impossible due to the difficulty involved in performing a thorough cleaning. The one I tried could not be disassembled enough due to the basket being permanently crimped onto the shaft during manufacture. Even if the inside of the basket is sparkling clean, it's the backside, between the basket and tub where fabric lint, moisture, and bacteria collect.

Maybe it's best to deal with the mess either with a filter between the centrifuge and fermenter, or by clarifying in the fermenter. Have you ever tried fining with gelatin? works wonders.


Could you elaborate on the 'fining with gelatin' concept, please?

If you mix 5gm of gelatin powder with 125ml of off boiling water and add it to a corny keg of beer while transferring it will help it to drop bright in the keg fridge over a couple of days.

Here is a guy using a washing machine to brew all grain, 12 quick video's. Following in Butch's footsteps? :D

WOW and no walls to wash down. COOL.

Makes me wish I was a beer brewer.

Much to think about. I think I'd need a RIMS or HERMS device for heating that recirculating wort. I brew a lot of high-dextrin beer, and mash temperature gets a little critical.

Heck with beer, I'm thinking just use it to spin dry the grain and get every last bit of wort out. On the other hand, I could see me doing an all grain run in it too though...

Just think though, spent grain dry enough to vacuum out with a shop vac?? AWESOME!

Really wish I hadn't seen those videos..

Now I'm considering making more attempts at all grains with a setup similar to that guy's.. It looks way easier than the process I had a few years ago.

Go for it Butch, don't let past failures prevent reaching your ultimate goal.
Once you get there, I will have a go.


Cheers. :rkn:
