Storage tips

  • Blowing cold air through canola bins

    Storage tips

    As we exit the winter period of really cold days, growers may wonder whether running fans on cold days to substantially drop the temperature of stored canola is worthwhile? This is not a researched scenario, but we asked grain storage researcher Joy Agnew of PAMI for her thoughts.

  • Tough or damp canola: Storage risk

    Storage tips

    Canola harvested at 15% moisture may not last long in storage before spoilage begins. How long is hard to predict. If warm, spoilage could start within a matter of days. If stored cool or cold, canola may last longer without spoilage, but this bin will become very unstable with any stretch of warm weather.

  • Slow harvest and storage risk

    Storage tips

    When harvest is slowed by rainy, cool days, combining often occurs in short spurts. In those spurts, the first and last loads of the day are often tough. This can mean an increased storage risk. Condition these bins with aeration to even out moisture and temperature. Consider filling bins to only two-thirds capacity to allow for improved air flow.

  • How to check bins

    Storage tips

    The best method, even with bin monitoring cables, is to remove about a third of the canola. This disrupts the moisture cycle and helps to stop any heating or spoilage that may have begun in the central core. While unloading, feel and smell canola as it comes out of the bin.

  • Storage risk: Can canola be too dry?

    Storage tips

    Not really from a storage risk perspective. When canola is very dry, one risk is that seed could start to crack if handled aggressively.

  • Storage: Hot canola is at risk

    Storage tips

    Canola binned hot, even if it has low moisture, low dockage and low green, should still be put on aeration. This will even out the temperature throughout the bin and help remove moisture from respiring seed. Even at low moisture, convection currents within the bin could concentrate this moisture. For safe, long-term storage, canola should be conditioned with aeration to less than 8% moisture and cooled to 15°C or less.

  • Harvesting at 30°C: Cool that canola!

    Storage tips

    Canola storage experts recommend that hot canola be put on aeration for cooling – even if it’s dry. That’s because air currents within the bin can concentrate moisture at the bottom of the central core — creating a possible start point for heating.

  • The right bins for canola

    Storage tips

    Fan capacity is an important consideration in a canola bin. Airflow of 0.1 to 0.2 cfm/bu is needed to condition (cool) a bin of canola. If adding supplemental heat to dry canola, airflow of at least 0.75 cubic feet per minute per bushel is recommended. If fan size is insufficient for the job, fill the bins part way to improve airflow.

  • Check for spoilage

    Storage tips

    This is steam coming off canola heating due to high moisture. This was not a welcome sight for the grower.

    Steam coming out of bin doors or snow melting off one bin while remaining on others is a quick clue — but don’t use these as your only indicators! Spoilage usually starts small. Even with temperature cables, start points are not always detected until some of the grain is already damaged.

  • Keep an eye on bags, patch holes

    If leaving bags for the winter, watch them regularly. Feel them for warm temperatures. Probe them if possible. Tape up any holes that may occur due to wildlife or any other damage. Spoilage in bags often starts around holes.
