What experts want most in on-farm grain storage
By Rod Swoboda

For storage bins, not drying bins or dryers, Charles Hurburgh, professor of ag engineering at Iowa State University, observes that many on-farm grain bins need a good monitoring system to keep track of grain temperatures.  It's hard to track grain temperature and maintain grain quality in large storage structures.

Hurburgh says a system that records temperature data over a period of time is most useful.  Increases in temperature of stored grain indicate heating, alerting farmers to take prompt action.  You'll either have to remove the grain or run some air through it with fans to prevent spoilage.

"In the larger bins there's not practical way to manually take the temperature of the grain and get a representative reading," says Hurburgh.  "Take a normal thermometer, shove it in the grain, and you have a temperature at that point.  But grain is a good insulator, so only 10 or 15 feet away, grain temperature could be quite different. 

The most common monitoring systems drop a wire into the grain at several places, with thermocouples ever 10 feet or so.  You get a readout on each cable.  If there's 50 feet of grain, there may be five or six thermocouples reading temperature, and you have four or five cables in the bin.  So you get 25 or 30 readings.

That increases the odds of finding something wrong, such as hot spots.  It doesn't always mean the cable will go through the hottest grain, but if you get a spot where the temperature is starting to rise, you know somewhere near that thermocouple, there's a problem.
