What is everyone's opinion on installing heating units on air dry bins ??
We have four 48' diameter air dry bins. Each bin is 60,000 bushels and have two 10hp. centrifigal fans on them. We are considering adding heating units to help with wetter grains/ speed up the process some what. Do we install them on both fans per bin or can we get by with one?? Will this even be cost effective or is it a waste of time??? (Approximate cost is $6000/bin) What is everyone's experiance ??? Thanks

I believe you need 1 cfm/bu to add heat efficiently and even at half full and 2 - 10 hp fans you wouldn't have that much airflow. For an expert opinion, you might try contacting the stepsgms.com company and ask the owner (***) about the cfm. His product might be useful because anytime the fan is on and the relative humidity is too high (70-75%) you are adding moisture that has to be removed again....
We have 48’ diameter 50,000 bu bins. We only have single phase power, so we went with two 15 horse (max for single phase) axial fans per bin with super low temp burners on each fan. These burners basically lower the air humidity to the level I choose so drying can still take place in less than ideal conditions. We also have temp and moisture cables and the system automatically turns fans and bu...

The way we handle most falls is that we only fill each bin half full. That seems to allow us to get by the first half of the harvest. After two weeks of air we fill the bins full and leave fans on. Just wondering if the extra heat will help/.pay??
I have multiple air dry bins. One of which is a 48’ Dina bin. We have a weather station, plenum sensors, dual temp moisture cables, 5 in the 48’. 3 high speed 30Hp Kego fans. Enough Hp to push air thru the entire column of grain. If you look at the grain as a column of water vapor and how much CFMs are need to push dry warm air, pressure creates heat and that much Hp creates pressure, thru the gra...
