Problem: The Weight of the flour does not directly equal the Volume of the flour. That is why in baking, flour is generally measured by weight, not volume. As you pour the flours from the sacks into the storage containers their volume will increase due to aeration (anywhere from 7-12%) depending on how you pour.
IF you take the time to pour about 10-lbs of flour (at a time) and then shake the container to "compact" it and remove the air encorporated during pouring from the bag - 10-Gal/40-Qt should work. I just tested this with a 5-lb bag of bread flour into a well marked 6-qt container ... it was just under 4-qts; when I shook to compact it for about 10-seconds - it reduced down to about 3.75-qts.
So, you could probably get away with something like a 40-qt bucket
- if you jostle it a few times as you add the flour. If you want to go with a different shape - rectangle instead of round and have a little wiggle room without having to jostle it ... then you have a 13-Gal (52-Qt) option
like this one.
If you have a restaurant supply store in your area you might check with them to see if they have any other options in their catalogs. The links I posted are from the restaurant supply store in my area where I shop.
Hope this helps.
