Spent grain container??

I have a local brewery that provides me with spent grain.  Right now we use old chemical totes that we wash out and cut the top out of them so it's easy to load with their forklift.  The problem is unloading the grain from the containers once we get them home.  If you try to tip them, the aluminum bars on the outside of the containers bend and break so we are forced to shovel from the top.  Has anybody made a container that a door opens on the side or any ideas on a container.  Any input would be appreciated.  Thanks

Put them on a platform and make a slide opening in the middle of the bottom. It won't get everything out without a funneled base, but it should get it empty enough to where you can tip it over without breaking anything

I saw these stacked up at a friends house with seed corn in them.  Not sure if they would work for your situation.

The spent Grains that we get are soaking wet, so trying to keep the liquid from seeping all over the brewery is the issue with putting a door on the bottom or a pro-bag.  Thank you for the input though.

There are options out there, they just cost money. You would just have to line the collapsible containers with plastic but you would be able to break them down as you got to the bottom

Back in the 70s a lot of farmers made a grain bin 4 ft wide, 8 ft long with a slope to the rear that fit in the truck bed.  Angle iron frame and plywood,  would hold 50 bushels,  end it up and 1 person could load it.  With a little care, 3 sheets plywood,
