I wonder if you are talking about the perferated panels under the chaffer and the sieve, for they will never damage any crop and will let out some dust or fm. The available perferated boots for bottom of elevators will also let out some fm if you keep them scraped clean. I would say most loose dirt and fm will be blown out before it gets under the chaffer so benifits are somewhat limited in my opinion. When your in the conditions that dirt just wants to stay with plant the more screening the better. Ideally set up you header with screened bottom and the proper pickup to shack as much out of possible right away. I would someday like to see the bottoms of clean grain and tailing perferated with about 1_2 inch clearance to auger flighting so there would always be a cusion of beans there with no pinching between flighting and trough. We have found that we can get bone dry beans down to shoe undamaged and than check or split them between auger flighting and trough. In that case we just trimed auger flighting to make room for bean inbetween flighting and trough. Does anyone know what is different between popcorn augers and standard. Maybe the popcorn auger is accomplishing that clearance. Does anyone have a good plan for slowing them augers down by about 50% for edible beans. I think we could maintain less than .5 % damage and fm with a couple of these things. We do enjoy some of the finest samples in the bean plants around here as it is but I like to go all the way. As for bean sieve we have never installed on. The way it sounds that sieve works great in soybeans so it will surely work in navys. Hope this helps!!! Dan
