been close to 10 years sinse harvesting tough grain , fall rye or hard red spring wheat at 16 to 17% moisture. Learned quite a bit from that experience. Having 2 different sizes if full floor aeration grain bins , 3 bins as 18 foot diameter Westeel widecore style net capacity perhaps 4,700 bushels of wheat when level full to within an inch of the top of wall ( eave ). Second set of bins , my older westeelRoscoe 3850's ( full floor aeration as well ... 2 with 13 inch stands , other 2 with 5 inch stands supporting the floor. 19 foot diameter bins , not quite as tall as the widecore bins ). Perhaps 3500 net or 3600 net bushel capacity bins. Ended up with a bin only half full , compared to the other level full close to top of the walls. Big time difference after running fans for a week , grain on the top of half full bin , much drier than the other bins filled to the top. Shoveling top level is important. And if a guy happens to have extra bin capacity , only filling bin half or 2/3's full , can condition and dry grain quite a bit sooner. Side note.. 10 years ago , I like many farmers was a turn the fan on as soon as bin filled , and leave it on 24 hours a day , until grain 14.5% moisture average .
I agree with his ( their ) observations and conclusions. But it takes a bit of time and thought to accept , as it goes a bit against my understanding of drying grain with natural air , aeration grain bins
The study is incomplete because they didnt out a value on the warming of the corn during the day. That is moisture out at night warm ir 15 degrees that's a point could be a trade off there

Hi, This may be true in Humid areas , But in Dry areas , will this effect be same?

This makes no sense, just put a pre heater in front of your fan and simply take all the humidity out of the air.
Not counterintuitive at all. That's really basic HVAC knowledge. But you still would want to have it off if it was cold and raining.
