Grain Aeration

From 100 tonnes to 22,000 tonnes, grain pedestals and fans will assist grain cooling, condition grain in store and form part of a professional crop storage system.

The purpose of grain aeration is to maintain a consistent relationship between grain temperature and outside weather conditions that could cause product deterioration through fluctuating temperatures.

A grain pedestal system from McArthur Agriculture, manufactured by Martin Lishman, allows you to change the temperature of your stored grain using outside air that is a different temperature than the grain. Most of the time this will be for grain cooling, but there may be situations where you want to raise the grain’s temperature. The goal of grain aeration, therefore, is to change the temperature of the stored product economically, efficiently and to the benefit of the final product.

Grain pedestals are free-standing, metal, vertical ventilation ducts that are fitted with a centrifugal fan that sucks air through grain, cooling it to conserve quality. Any combinable crop can go through the grain cooling process directly off the grain drier, improving daily output and making grain safe for long term storage. Grain aerators from McArthur Agriculture can be fitted as part of a bespoke grain processing system or turnkey solution.

Why Grain Cooling Is Important

Once grain is dry temperatures must be reduced as quickly as possible to avoid spoilage. The main causes of spoilage in stored grain are fungi, insects and mites. Temperatures above 15°C increase the risk of insect and mite populations developing.The HGCA Grain storage guide advises grain cooling should commence as soon as the grain comes into store.

GRANIFRIGOR™ grain cooling units can cool crop to below 12°C in a matter of days independently of weather conditions.

Complete Control

The GRANIFRIGOR™ grain cooling units refrigeration and dehumidification technology ensure that grain stored in a silo or on a ventilated floor can be cooled to below 12°C regardless of weather conditions.

Eliminate Risk

Prompt cooling protects against development of insects, microbes and fungi. Once the crop is cool it remains cool ensuring long term storage without quality losses.

Cost Effective

When a GRANIFRIGOR™ grain cooling unit is used no costly expenditure on fumigation or other chemical treatments is required, drying costs are reduced and respiratory.

Do You Meet HGCA Cooling Guidelines?

Grain Cooling Targets

Within 2 weeks Cool to below 15°C To prevent saw-toothed grain beetles completing their life cycle
Within 3-4 months Cool to below 12°C To prevent grain weevils completing their life cycle
By end-December Cool to below 5°C (except malting barley) To kill surviving insects and prevent mites increasing
