Ghetto Grain Mill

maybe your running the mill to fast

Thanks for your feedback everybody. Today I brewed 2 American Ales using grain milled @ 0.9mm. It took a little bit of encouraging to get flow started, but once it was going it was all good.... plus my efficiency has gone from 60% with home brew milled grain to 75%.

Cheers

Nice one!

As above.
Try slowing it down.

I was running the mill very slowly (it was stalling often because of it). Running on my 18V drill I can't mill any slower.

I mill one batch on Thursday and one batch on Friday to brew two batches on Saturday morning. Will moistening the grain cause me any problems with this?

 

[Ducatiboy stu]

I would only moisten just prior to milling. You only need the grain sit for around 20-30mins

With the extra moisture in the grain it wont stay fresh to long. You run the risk of mould and also the breakdown of the starch.

It is generaly not good to keep milled grain unless you vac pack it

there's an ozito drill that has loads of torque for around $100 which allows super slow speeds without struggling.

I flipped my mill over so I could attach the drill to the table. It never leaves the table but frees me up to do other things while I'm preparing my brew, like drinking :drinks:

I bought the ozito drill and milled with 100ml water in 4.5kg grain. Can't believe how well it worked!

All we have to do is convince the rest of the brewers that grain wetting/moistening DOES WORK.

You just proved it.

I probably can see more unsplit husks after

I probably can see more unsplit husks after

And thats what you want. Husks that are intact and whole.

 

[jhsbaker]

I looked at it closely, all of the grains are crushed and there is quite a bit of flour (the husks are on top so you can't see it).

I got the same utilisation as last session with dry grains with 0.9mm gap (but last time every husk was ripped in half).

You want a fair amount of flour.....upto 30%

Also sparges easier

 

[Dan Pratt]

I just bought a mill/motor, is there a way to check % of flour?

 

[Ducatiboy stu]

Sift it out

 

[spog]

As above, by weighing the amount of flour g/kg compared to the amount of grain milled g/ kg.

 

[Ducatiboy stu]

30% is about as much as you want, and even at that amount, sparging can become more fun than swearing at your kids for smearing vegemite all over your lounge

The whole husks greatly help in this situation...and rice gulls
