West of Dalhart, Texas | Actual Moisture - 15.5 (base moisture) = Difference x 1.2% (per point of moisture over 15.5% base moisture) = Dockage. 100% - Dockage = Percent actual corn. (I didn't use 1.2% dockage in my previous reply, I used the scientific actual dockage of 1.1614%)
So, 25.5% moisture - 15.5 base moisture = 10 points of moisture x 1.2% = 12% dockage
100% (if it were 15.5% moisture) - 12% dockage = 88% of the gross load
88% x 1000 bu = 880 bu dry grain
Another, 20% moisture - 15.5 base moisture = 4.5 points of moisture x 1.2% = 5.4% dockage
100% (if it were 15.5% moisture) - 5.4% dockage = 94.6% of the gross load
94.6% x 1000 bu = 946 bu dry grain.
I can email you an Excel file you can plug in ticket and moisture and shrink in spreadsheet form tomorrow. Drying costs are highly variable. Depends of course on electricity and burner fuel cost but, also ambient temperature and humidity play a huge role in drying. Also there are dryers that are 30% plus more efficient in doing the job than others. Fuel, location, moisture of grain (it cost less per point of moisture to remove 10% than it does to remove 5% moisture) and, age of technology (how old the dryer is) play a big role in cost of drying.
