Aeration

Silo aeration is designed to ensure that grain stored in silos remains at low temperature, low moisture, and low insect and mould activity levels. Grain stored in silos may not always be below the recommended moisture level. Aeration uses fans and ducting to blow outside (ambient) air through the grain in order to keep it cool. Aeration assists in maintaining grain quality and fumigation in a silo by:

• Reducing mould
• Reducing insect development
• Lowering grain temperature through aeration cooling
• Increasing storage longevity

How it works

The aeration fan works by creating a current that circulates through the grain, which in turn has the ability to cool the grain. Aeration cooling allows for longer-term storage or low moisture grain by creating desirable conditions for the grain.

Fan-forced Fumigation

The NGS Fan-Forced Fumigation system enhances the longevity of grain storage, ultimately helping farmers increase their bottom line and improve on-farm safety.

Fan-forced fumigation system is an efficient and easier way to fumigate your silos at ground level. The system works by circulating air inside the silo from the aeration fan for an even and consistent dose of phosphine gas. Recirculation of phosphine gas within the silo controls pests at all life stages, thus reducing the impact of insect pests on grain quality.

As pictured below, included in Fan Forced fumigation is a one-piece, heavy-duty galvanised pipe fitted from roof to bottom barrel on a silo connected to an aeration fan and sealed tray box for Phosphine tablets.
