Throughout the upcoming blogs, I intend to go through the basic science of how grain aeration dries or wets grain. I will take you on the journey of how this project started, what we learned along the way, and in the end I will give you the specifics that you need to know to control your fan. The conditions that will result in drying — turn the fan on; and conditions in which there will be wetting — turn your fan off. There are very few people who know about this, so you will be on top of very recent research. I am excited, not only in telling you about the new control strategy but also in educating you as to why it is the ultimate way to control your aeration fan. Comments of course will be welcomed.
