DIY Mill Hopper - lbs / sq ft.??
 
Trying to sketch up a quick hopper for my grain mill. Does anyone have a good guess as to how many lbs of grain you get per sq ft??

Thanks!!

This doesn't answer your question, but I used a scratched better bottle with the bottom cut out fo rmy hopper. I can fit around 40 lbs of grain in the 6 gallon carboy. If in doubt, go bigger.

What kind of grain mill do you have?

Ahh but it kinda does answer my question. Thank you! And I meant to say cubic feet. Not square feet.

6 gallon carboy = .802 cubic ft. (1 gallon of water = 0.13368 cu ft. @ STP)

40lbs / .802 = 49.9 lbs / cubic ft. (this is an apporximation but will work well enough)

Thanks!!

Nice mill... I have a Barley Crusher with the 7# hopper... I might extend it at some point in the future... I wouldn't go much higher than 10-15# for a hopper though, unless you plan on making it more wide than tall. Or unless you plan on making it a more perm. mounting (where the mill and hopper sit, with the bucket to catch the grain)... I just wouldn't want to make it too top heavy and have it spill grain all over the place...

Glad I could inadvertently help! If you go too big on the hopper, it'll be a PITA. I've been happy with mine and I also like that I can see my progress from across the room. HERE'S SOME PICS...

ScubaSteve, what are you brewing that needs 40# of grain?? Are you doing a couple of 10 gallon batches in a weekend? I know we used 26.5# of grain for our 10 gallon batch (OG of 1.065)...

You probably want to fix that link too...

Thanks for the advise. This mill station is going to be a bit of a tank. I want to hold a 50lb bag of grain. I'm stepping up to 1.5 BBL batches. So it will be a stand alone station with a rather large trash can under it to catch all the stuff. I'm going to have it fully enclosed to keep the dust in. I have the motor and pulleys set up. I'll get pics for ya when I get closer to done.

Sounds pretty sick, in a great way... :rockin:

You planning on using one of the dust collectors like you seen in wood working shops? You might want to have that to collect airborne dust, to keep things cleaner (around the rest of your brewing area)...

I dream of the day I'm brewing batches that size...

How many pallets of grain are you planning to blow through in a month? :eek:
