| We've got one on our legs sucking out. Helped some, but did not totally elimate the problem while we were drying.
Don't think it caused any more problems pulling up hot moist air because the fans on the bins were blowing the air up anyways.
We've quit drying because of the cost of the propane so it's no longer a problem. What we found worked the best for us and it might not fit your situation there, but every morning I would go out and switch both distributors to each downspout and then punch each leg on just long enough to scoop a couple handfulls of corn. That would slide out what ever wings had settled in over night. When we dried corn we never had beans in the bin so I would just go sweep the bean bins after corn harvest was over and everything was good to go.
One other note, depending on how bad they plug up etc. I think it helped to go slow when we first started into a different downspout, just let maybe a quart of grain go up the leg and wait until you've heard it rattle through the downspout, maybe do it a couple or more times. I think this worked better for us vs just turning it on and hitting the auger that fed the leg and letting it run full speed right off the bat. I always thought that a few handfulls hitting some of the wet wings might tend to drag them loose and get them to fall on down, vs throwing a bunch of grain all of a sudden on them and having it back up before it had a chance to slide down if you understand my reasoning. | |
