N.W. Illinois | What do you have for a moisture tester? Most testers will not give a accurate reading much over 100 degrees of grain temp. I've found it easiest to cool the corn for a short while (whether spreading it out on a scoop, fine mesh screen, whatever) to kind of give you a general idea of your discharge corn moisture. Cooling the grain with air in the bin will usually remove more moisture. The best way to get a accurate reading is if you can pull a sample of the corn from the bin once it's cooled and test it. I then get a good idea what the discharge temp of the hot corn needs to be and use discharge temps to determine what the corn moisture will end up to be.
I've also found the wetter the grain coming out of the field the higher the discharge temp the hot corn will be coming out of the dryer. I've had discharge temps of 145 plus degrees before when drying 25% plus moisture corn. Under 20% the discharge temp might only be 125 degrees or less.
Finally pull the center of your bins when you have finished drying and move it around some. The last bit of corn going into a bin can be difficult to cool along with any fines that are in the center of the bin. A crust can form quickly which becomes a big pain in the butt. Hot centers in bins are the cause of most tragedies from farmers being buried in grain in bins. | |
