Smart Aeration Solutions for all Grains,
Nuts, and Seeds
What Harveston's Solutions Deliver
What are Harveston's Aeration Solutions?
Our experience, backed by many years of focused industry research, tells us that passing the right amount of ambient air, of the right quality, will gently dry any grain, nut, or seed. We design all our aerated storage solutions using that knowledge.
The resulting solutions consist of the correct number of highly efficient fans coupled to a distribution system specific to the amount and type of product being stored and a controller that senses both the ambient air conditions and the conditions within the product stack.
Our smart controller then delivers the right amount of air at the right time to reduce the moisture levels of the stored product to a preset target, and keep it there. There are limits on how much moisture can be dealt with using ambient air and the combination of fans, time and flow rate is all important in designing your solution.
​
Once the drying target is reached the controller then chooses the correct amount and type of air to ensure that the product stays consistently at the target moisture. It then sets about ensuring the temperature of the stored product is as low as possible.
​
In the case where the product is already too dry, our contoller will choose the right air to gently raise the product moisture levels.
​
With product at the correct moisture and with its temperature as low as possible all biological activity within the stored product is significantly slowed. Research has shown that mould growth does not progress, toxins are not produced and insect lifecycles either cease or are significantly curtailed.
​
Our solutions can be fitted to silos, rings, sheds, stockpiles or bunkers and can be retrofitted to almost any existing aerated storage.

What Harveston Solutions Deliver
Lower Post Harvest Losses
Research has shown that storing grains, nuts, or seeds in a properly designed and controlled aerated storage can minimise or even eliminate product quality degradation.
In fact, when operated correctly, aerated storage systems can improve product quality.
Gentle Product Drying
When using ambient air aeration to dry products, the drying rate is slow and gentle on the product.
The design of the aeration system is crucial for drying, as the required airflow rates can differ significantly from those used for conditioning and quality maintenance.
Consistent Product Moisture
Using ambient air to control moisture content is very cost-effective. When combined with an in-grain sensor, fan run times are regulated to achieve the target moisture content throughout the entire grain stack.
Correct and consistent moisture ensures that producers can maximise their returns.
Mould and Toxin Control
Biological attacks on stored products depend on moisture and temperature conditions that are outside the recommended storage parameters. Ambient aeration ensures these unfavourable conditions are not present in the stored product. Our advanced aeration controller can sense biological activity and warn you of its presence.
Vermin and Pest Control
​The need for fumigation is significantly reduced when ambient aeration is in place and run correctly. Both vertebrate and invertebrate pests require specific conditions to attack stored products. Ambient aeration aims to lower the temperature in the stored product to a level where the lifecycle of the most common pests is significantly slowed or stopped altogether. For invertebrate pests, their biological processes slow down to the point where they cannot feed and eventually starve to death. There is also a research hypothesis that regular replacement of the air within the stack disrupts the transmission of mating pheromones.
Reduced Labour Costs
A well-designed and controlled aeration system significantly reduces the need for storage testing and decision-making about fan operation. Modern control systems allow producers to monitor the status of their storage from the comfort of their lounge chair.
These systems handle the heavy lifting, ensuring fans run when the stored product needs it and when ambient conditions are suitable. However, producers should still regularly check their systems to ensure they are operating correctly.
