Nw Iowa | Seen your post after I did my post below. Corn has to be cooled to work, you have to have some kind of aeration to at least move some air but will not cool whole mass. I think what op did was correct and that was to just put a auger in floor. Whole floor conveyor would be nice bu a lot to go wrong and I guess I would worry about moisture freezing or seizing it up. When we did it we actually just put auger thru the wall, would just put a downspout tube with support and than put auger in when ready to empty and than pulled it all out when we filled with equipment. We had two of them in a 100’ building and was cheap and quick and didn’t fight water issues. If you build a building, builder will help you design pole spacing so you can go up walls 4’ to 8’ with a liner or you can purchase free standing walls but I don’t like them as they are hard to clean and you lose a lot of capacity. Cement walled bunker type building with a roof would be real ticket. But biggest issue is capacity. A 60x120 building would be 7200 sq ft x.80 equals only 5760 bu per ft plus peak so 4’ up walls only gives you alittle over 23000 bu plus peak so maybe a short 50000bu. That isn’t taking anything out for wall thickness so I am guessing you lose another short 1000 bu. So with cement you could easily have over 3$Or 4$ a bushel. At 4$ you could have a bin and a dirt floor storage shed. Bins are expensive but easy to fill and easy to empty and easy to keep grain in condition. Dual purpose is nice but machinery will sit out until shed is empty. Other issue we found if anything was parked in shed it was covered in grain dust. Ideal situation would be cold dry corn coming in out of field and put directly in building. Not as much dust, corn would keep fine without aeration and would be first to move, so would start going out in Nov, Dec or Jan which looks like OP is doing. | |
