Food production is a highly valuable industry in Australia. With the available commodity dryers and grain aeration systems, looking after food in the production process and keeping its quality high is made simpler. One way to keep grain quality high throughout the production process is to take it through aeration.  

What is aeration?

Aeration can be described as pushing a front of ambient air through the grain bulk, while it is in storage. Its purpose is to keep stored grain cool to ensure minimise the risk of insect infestation and/or mould. This process is managed via silo aeration systems. Silo aeration systems consist of high airflow fans that are attached to your sealed silo via a hole in the side or conical base, and sealable roof vents that are easily installed at the top of the silo.  When paired with an automated aeration controller, the aeration process becomes more precise. Controllers use wet-bulb temperature readings to determine the best time to turn-on aerators, ensuring that only cool, dry air is utilised.

When it comes to finding the appropriate aeration system for your silo complex, it is advised to seek expert advice from professionals. The Grains Research & Development Corporation (GRDC) have published a useful guide to understanding aeration systems which is publicly available here:

The benefits of aeration?

Protecting the quality and ensuring the longevity of your stored grain is critical to your bottom-line. Grain maintains its optimal condition if it is stored in an environment that is cool, low in moisture, low in insect activity and also low in mould activity. When grain is stored correctly, it will not only last longer but it will provide more value for merchants and consumers.

Keeping the grain cool will:

  • Reduce insect infestation
  • Prevent mould growth
  • Assist in balancing moisture levels
  • Assist in balancing temperature
