Discover the considerations with aeration for cooling or for drying.
Source Link GRDC Author: Philip Burrill, DAF Qld. Take home message Seek advice to ensure the right size aeration fans and associated equipment are fitted – ducting, roof vents and fan controller. Not all silo suppliers get it right. Recommended aeration cooling airflow rates are 2 to 4 litres of air per second, per tonne […]
Grain Storage Fact Sheet February 2015 Results of aeration trials supported by the Australian Oilseed Federation Oilseed Development Fund and the Australian Sunflower Association as part of the Broadleaf Cropping Alliance, a Grains Research and Development Corporation funded initiative. Sunflower growers can use aeration drying and cooling to successfully manage a range of seed moisture […]
Grain aeration provides growers with a powerful tool to maintain grain quality during harvest and storage. Aeration cooling may not eliminate the need for chemical insect control, but it will dramatically slow insect development. Key Points Grain temperatures below 20°C significantly reduce mould and insect development. Reducing grain temperature with aeration cooling protects seed viability. […]
Grain storage consultant Peter Botta gives useful tips on cooling aeration in silos as part of a grain storage series for the GRDC’s Ground Cover TV
Grain growers are using silo aeration on their stored grain to gain harvest flexibility and more marketing options. Silo aeration can be used to cool grain and keep insect populations low. But it can also be used to dry the grain – allowing greater tolerance of moisture at harvest. But aeration drying makes the task […]
Grain at typical harvest temperatures of 25–30°C and moisture content greater than 13–14 per cent provides ideal conditions for mould and insect growth (see Figure 1). There are a number of ways to deal with high-moisture grain — the key is to act quickly and effectively. Key Points Deal with high-moisture grain promptly. Monitoring grain […]
