“Damp” canola may not be safe, even if cold

Freezing tough or damp canola by running cold air through the bin can be a short-term storage solution for canola that couldn’t get dried before winter…but check that canola regularly. This is not as safe as you might think.

Canola quality with winter or spring harvest

Combining canola after the ground has frozen can work fairly well, especially for standing crop. In fact, when putting ice and snow covered canola plants through the combine, colder temperatures (-10°C to -20°C) may be better than temperatures around 0°C.

Bin sensor shows rising temperature. What to do?

ANY unexpected rise in temperature should be a clear signal that action is required. Once an area starts to warm up, the reaction has started and the canola will probably just get hotter and hotter until spoilage starts. Then spoilage will spread until the whole bin is damaged.

Bin safety tips: Stay out

High moisture harvest means steady action around the bins – with oversight of dryers, aeration fans, latches, hatches, augers and trucks. The best advice is to stay out of the bins entirely and keeps all guards and shields in place – just in case.

Tips for drying tough and damp canola

The ideal goal for safe long-term storage is to have canola rest in the bin at 8% moisture and less than 15°C. All canola should be conditioned after it goes into the bin. For tough and damp canola, the spoilage risk is much higher. Here are some tips to manage that tough or damp canola.

Safe storage chart for canola from the Canadian Grain Commission (2019) which states that canola spoilage occurs when initial seed temperature ranges from 10°C to 50°C with respective moisture from 12% to 7% moisture content.
