What Sets O’Mara Drying & Aeration Bins Apart
- Custom-Engineered for Your Operation
Every bin is designed to meet your volume, grain type, and airflow requirements. Whether you’re drying corn, soybeans, wheat, or specialty crops, we tailor the system to optimize performance and reduce bottlenecks.
- Integrated Aeration & Drying Capabilities
Our bins feature full-perforation floors or ducted systems paired with high-capacity axial fans or centrifugal fans, ensuring uniform airflow throughout the grain mass. This prevents spoilage, reduces hotspots, and extends storage life.
- Modular Design with Burner-Blower Option
Add a burner-blower system to convert your aeration bin into a heated-air drying solution. Ideal for producers looking to expand their drying capacity without the capital investment of a separate dryer system.
- Sensor-Ready for Real-Time Monitoring
Our bins support temperature and moisture cable systems, giving you full control over grain conditions with remote alerts and detailed trend tracking. Monitor from your phone, tablet, or PC—maximize shelf life and peace of mind.
- Turnkey Aeration Attachments
Already have bins in place? We offer aeration retrofit packages that integrate seamlessly with existing bin structures. Protect your investment and upgrade your capability with minimal downtime.
How Our System Works
- Airflow Management
Large-volume fans drive controlled airflow through the grain, either pushing from the base or pulling from the top.
- Even Distribution
Air is directed through perforated bin floors or in-floor ducts, ensuring even exposure across the entire grain depth.
- Moisture Removal
As air moves through the grain, it lifts moisture upward and outward, reducing kernel moisture content to safe storage levels.
- Temperature Regulation
Continuous aeration limits condensation, suppresses insect activity, and prevents grain heating or grain spoilage.
Why Choose O’Mara Aeration & Drying Bins?
- Preserve Grain Quality
Protect against mold, mycotoxins, and heat damage with uniform drying and stable storage temperatures.
- Increase Harvest Flexibility
Harvest earlier at higher moisture without relying entirely on commercial dryers. In-bin drying buys you time and improves harvest logistics.
- Lower Operational Costs
Natural air drying (NAD) using ambient conditions can be significantly more cost-effective than propane- or natural-gas-based drying.
- Boost Return on Storage Investment
Grain stored properly with in-bin aeration maintains grade, weight, and marketability, translating to stronger margins at sale.
Technical Specifications & Considerations
- Fan Types: Axial or centrifugal (single- or multi-phase), sized for grain depth and bin diameter
- Airflow Rates: Configurable to deliver optimal CFM/bu—typically 1 to 2 CFM/bu for aeration, 1.5–5.0 CFM/bu for drying
- Flooring: Full-perforation, flush-floor, or channel duct systems
- Monitoring: Optional temperature/moisture cables and controllers
- Grain Types Supported: Corn, soybeans, wheat, canola, oats, popcorn, barley, specialty grains, and more
- Weather Integration: Systems designed to leverage low relative humidity periods for natural air drying
