Grain Drying Silos Australia
Australian Made Drying Silos for Moisture Control and Grain Quality
WHY GRAIN DRYING IS CRITICAL FOR STORAGE
Moisture is one of the biggest risks to stored grain. Grain that is too wet can lead to:
- Mould and spoilage
- Insect infestation
- Reduced grain quality and marketability
- Increased risk of rejection at sale
Drying grain to the correct moisture level ensures it can be stored safely for extended periods while maintaining value.
- In most cases:
- Cereals should be stored below 12% moisture
- Oilseeds typically require 5–9% moisture
ADVANTAGES OF IN-SILO GRAIN DRYING
Kotzur drying silos provide a practical and cost-effective alternative to traditional grain dryers.
- Earlier harvest opportunities reducing in-paddock losses
- Increased harvest window and flexibility
- Lower capital cost compared to dedicated grain dryers
- Reduced energy consumption compared to conventional drying systems
- Minimal grain handling, reducing labour and equipment costs
- Gentle drying process that protects grain quality
- Ability to both lower and manage moisture levels
Drying silos are particularly valuable in humid or variable Australian climates, where harvest conditions can be unpredictable.
How Kotzur Drying Silos Work
The Kotzur drying silo uses a specially developed drying cone/plenum. The air is forced into this plenum and then passes through the grain mass.
Different drying silo models, fan combinations and grain have varying specifications, however the typical airflow is 15-20 litres per second per tonne of grain or a complete change of air in the silo each 25-50 seconds.
This airflow is 10-15 times that achieved using conventional aeration. The plenum design ensures that this air flow is uniform through the grain mass and is not restricted by screens etc.
Designed for Australian Conditions
Kotzur drying silos are:
- Manufactured in Australia
- Engineered to Australian Standards
- Designed for a wide range of climates and grain types
- Built for long-term performance and durability
Our systems have successfully dried a wide range of crops including:
- Wheat
- Barley
- Canola
- Maize and corn
- Sorghum
- Pulses and oilseeds
Efficient and Cost-Effective Drying
Compared to traditional high-temperature dryers, Kotzur systems offer:
- Lower energy use
- Reduced risk of grain cracking or damage
- Improved germination retention
- No need for complex internal screens or perforated floors
- Faster cooling after drying
This makes in-silo drying a practical solution for small to large grain operations across Australia.

- Wheat capacity based on typical consolidated/compacted bulk density in silo.
- Max. Load based on engineering design. This may not apply to products other than grain.
- Auger lengths are indicative only and are based on 35° angle.
- Pilot/Escort vehicle requirements may vary in certain locations (e.g. metropolitan areas).
- GPE Models are built on site – price does not include on site erection cost.
- Due to changes in OHS regulations, from Jan 2003 roof manhole and internal ladder are no longer supplied.
- One Sight Glass per wall strake is standard.
- Nominal outlet height
Actual tonnage capacity achieved in silos will vary according to a number of factors including bulk density (test weight), angle of repose and headspace volume (for aeration).
