Managing outdoor bunkers and piles presents some unique challenges, and almost every facility has some different challenges, as well.
First and foremost, I would certainly segregate, trying to do my best to avoid mixing any of the challenged grains, especially on moisture, damage, and so forth with other good grains.
I know that it is very difficult, especially when your surface or your base already has some damage. The challenged grain just naturally wants to mix in.
I’d suggest the following things:
- I recommend a good reclaim plan based not only on speed, which is generally very important, but also on quality segregation. Clearly communicate that plan to your employees. In the case of those who might be using contractors, make sure that they understand that, as well.
- Use a grain dryer, if available. While moisture meters determine averages, perform a close examination of the sample to determine if it contains a large quantity of swollen or sprouted kernels. If so, this type of grain needs to be dried. You can regulate how much heat is used with your dryer, which have tremendous airflow rates. They are a great tool to dry, cool, and condition the grain. Additionally, it can help reduce odors associated so many times with grains reclaimed off piles, bunkers, etc.
- Be prepared in some circumstances to set aside or possibly discard grain that is heavily damaged or insect-infested. Instead of dealing with this material during reclaim, setting it aside gives you some time. These are tough decisions to make and have financial impacts, but don’t attempt to “blend away” this type of material. You need to take into account blue eye mold, mycotoxins, and the reintroduction of excess moisture into a stable grain mass that could have serious quality and safety impacts down the road.
