| A Stormor bin salesman told me in 1972 when I got the second bin (27')to pull air down through the corn and turn the fan on when the first corn went in and not turn it off until spring. He said 25% corn would work. I have not went that far but we do put 21-23% corn in it and start mid-September if possible. The only time it gave trouble was when we had about 2 weeks of cloudy foggy days on a bin full of corn. I panicked and got the 24" 7.5hp fan and started blowing air up through it(reversed air ) of course the drying fronts met somewhere in the middle and the corn began to heat. I had to take some out and send to an elevator to dry. A stirrator helps but isn't necessary. We have an 18"fan with 3 hp motor on a 30' bin(7-42" rings. Good luck part of the key is getting night time temp down under 50 and enough cfm air flow per bushel. Good luck | |
