Grain Drying Silos

McArthur Agriculture

McArthur Agriculture are delighted to be a UK supplier for Sukup Europe, delivering grain drying silos that are known for their quality, strength and efficiency.

 

Grain drying silos offer an unmatched combination of functionality and value and are in many cases are a preferable alternative to new grain storage buildings with integrated grain drying floors. If you are considering new grain storage and drying infrastructure for your farm this is an option that needs serious consideration.

The grain drying silos store grain up to 7.5m deep in outdoor storage bins and the drying process must start as soon as an even grain layer 0.5-1m covers the floor of the silo. Warm air is then introduced through the fully perforated floor with the lowest grain layer being dried by the constantly stirring 2 – 5 vertical stirring augers mounted on the horizontal cross-tube. The airflow through the grain is increased by up to 33% because of this stirring, avoiding wet spots in the grain.

Uniform drying of the entire contents of the grain drying silo is achieved by the action of the vertical augers stirring back and forth along the horizontal cross-tube, which slowly rotates around the silo. As this rotates around the grain drier horizontally, it forces the augers down to move in and out on the cross-tube, bringing the dried grain from the bottom of the silo to the top ensuring a complete mixing of the crop.

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
