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.
