Leesburg, Ohio | A few days back, there was a thread on using a fan on the turnhead of the grain leg to remove red-dog, or keep it from blowing into other bins. We put one on our leg this fall, and had not used it yet. We have been using it and are not happy. It blows into the turnhead, supposedly to keep the chaff and moisture from the bins from blowing up the pipes and into other bins. The result is it apparently blows the red-dog out of the wet corn stream through the gap in the turnhead pipe, and blows it into whatever bin doesn't have a fan running at the time. End result is, we have had the load-out hopper bin plugged in the bottom with red-dog twice since installing the fan...it's not a good feeling to open up a 12" gate in the bottom of a full 3000 bu. overhead bin, and have nothing come out!
I would like to turn the fan around and have it suck out of the leg to get rid of the red-dog altogether, but I'm concerned that it would draw hot, moist air from the cooling bins up the pipes, condensing moisture out, and causing it to run back down into the center of the bins, causing more serious problems.
Any ideas or experience with a fan sucking out on top of the leg? | |
