Temperature to turn canola bins? Aeration in winter?

[MBgrower]

Id say your canola is too warm, i take mine down to freezing even when dry, never have trouble. If it is clumping u better seperate the clumped grain from the rest of the bin, as the tolerance for heated is extremley low.

I keep this chart handy. It is helpful in telling when you are out of time.

In '09 we'd bin canola at 15 plus moisture and maybe 10 degrees. In 11 days just like the chart says it needed to be going into the dryer or it would have been ruined in short order.

They make these things called dryers.

They work real gooood.

Farmers spend 100000$ on recreational vertical tillage but won't spend 10 grand on a drier. Sheesh

We had Canola which the Opi read 40f and there were still hot heated spots in the 5,000bu bin... between the sensors on the Opi.

Go to the top of the bin... smell the air at the loading/filling hatch... if it is clammy and smells like heating canola... well... you should be prepared for the rest of the story. Usually if half the bin is emptied... you will know what is up. 2 Super bees were needed to get rid of our warm spot... and we thought it was safe because it was 9 moisture when we put it in... and it was cooled. We Thought.

Let me get this straight Tom. Your saying your opis were showing around 5-6 celsius between the readings, and the hotspots were 30 plus celsius. You would think that the temp would of slowly climbed a degree or two every week on the sensor above the hotspot. I know my are going down roughly 2 celsius every week on the fourteen foot diameters, and 1-1.5 celsius on the fifeteen foot.

Agchat,

Was close to 10 years ago... part of the field was tough... but all easily blended to 9 percent moisture. Was High Acid... Bunge took it with no problem... and blended it so no discounts for heated.

When loading trailer at minus 30... steam...could sure tell something was less than ideal!!!

Scared me to say the least... good to recall and respect how unstable Canola can be!

Thanks for reply Tom. I guess my first reaction would of been faulty bin cable.

Sensors are every 4 or maybe its 5 feet if there is a drying front it can land between sensors. Better to shoot for 6 moisture then cool. There is a curing process that plays out and a bounce.
