Storage advice for high moisture grain

With wet weather hampering what is left of the Western Australian harvest, growers are advised to act promptly to deal with high-moisture grain.

Detailed advice to help growers manage grain which is over the standard safe storage moisture content of 12.5 per cent is outlined in the Grains Research and Development Corporation (GRDC) Grain Storage Fact Sheet - Dealing with high-moisture grain.

Techniques outlined in the fact sheet include:

  • Blending – mixing high moisture grain with low-moisture grain, then aerating;
  • Aeration drying – big volumes of air force a drying front through the grain in storage, and slowly remove moisture;
  • Aeration cooling — grain of moderate moisture, up to 15 per cent moisture content, can be held for a short term under aeration cooling until drying equipment is available.
  • Continuous flow drying – grain is transferred through a dryer, which uses a high volume of heated air to pass through the continual flow of grain;
  • Batch drying – usually a transportable trailer drying 10 to 20 tonnes of grain at a time with a high volume of heated air, which passes through the grain and out perforated walls.

In addition to the Grain Storage Fact Sheet, information about stored grain management techniques is available at the GRDC Stored Grain Information Hub at www.storedgrain.com.au

CAPTION: Drying silos, right, can help manage grain over the standard safe storage moisture content of 12.5 per cent.
