Before using grain bins, especially those not in service for some time, a thorough inspection is essential to ensure safety and maintain grain quality. Weather events, age, or lack of use can lead to hidden damage.
Experts recommend starting with a complete visual check. Inspect the bin’s alignment, look for dents, bends, and any separation between the roof, walls, and foundation. Check the sealant between the wall and foundation for cracks or damage.
The foundation should be inspected for cracks, uneven settlement, missing or bent anchor bolts, and loose connections. On the walls, look for rust, buckling, missing bolts, and damaged caulking. Examine openings, doors, and stiffeners for cracks, deformation, or loose bolts. Wind rings should be round and secure. Inside the bin, check for light entering through damaged areas, and inspect raised aeration floors for secure attachment and wall alignment.
Roof checks include inspecting for bent panels, damaged ribs, loose or missing bolts, and ensuring vents are in good condition. Electrical systems must be inspected for damaged conduits, loose connections, corrosion, and rodent damage to wires. Grain handling equipment such as conveyors, elevators, and downspouts should also be examined for alignment and structural integrity.
Cleaning is equally important. Using proper respiratory protection, sweep and clean all surfaces inside the bin, including ladders, vents, stiffeners, and aeration ducts. Remove debris from under floors and ducts, as old grain can harbor insects or mold. Where cleaning is difficult, empty grain bin insecticides may help control pests.
Structural damage can cause uneven grain loading, leading to possible bin failure. Poor seals or damaged parts can also reduce aeration efficiency and allow moisture to enter, harming grain quality.
