Latest Storage Technology.

Our Silos are fully forced ventilated and monitored via a unique scada control system that makes them ideal for long term storage of cereals. Grainstor can monitor the condition of the product at any stage to ensure product integrity is maintained, and in-fact enhanced, due to constant humidity controlled airflow.

Grading & Testing Services.

The Grainstors' state of the art testing lab can analyse and report on the characteristics of most cereal grain to support feed and flour milling requirements. We test moisture, KG/HL, protein, falling number, gluten and screening. We also test for pests and undertake fumigating & de-bugging when required to maintain the pest free integrity of our storage facilities.
