The Ukrainian grain storage market is transforming. The era of building “giants” from scratch has temporarily given way to pragmatism: reconstruction of existing capacities, replacement of components with energy-efficient ones, and restoration after war damage.

Together with experts from the leading Ukrainian manufacturer of grain storage equipment, KMZ Industries, and market practitioners, we have gathered the key points that grain storage owners should consider when modernizing their facilities.

Legal Foundation: Project vs. Technical Retrofitting of Grain Storage

The first mistake many make is starting work without a clear definition of the construction status. According to State Building Codes (DBN), it is important to distinguish between three concepts:

• Technical Retrofitting: Replacement of motors, fans, or individual sections with identical but more modern ones. This often does not require complex approvals.
• Capital Repair of Grain Storage Equipment: Restoration of damaged objects without changing their geometric dimensions or capacity. This was the scenario used to restore the “Service Grain” grain storage after a missile strike.
• Grain Storage Reconstruction: If you decide to replace a dryer with a more powerful one or add new silos. This requires a full-scale project, new technical specifications for gas/electricity, and an environmental expertise regarding dust emissions from the grain dryer.

Advice: Do not try to “hide” reconstruction as a repair. A discrepancy between actual capacity and documentation can lead to fines during the commissioning stage.

Restoration of Grain Storage: Fast or Cheap

The experience of restoring grain storage facilities since 2022 proves once again that restoration is always an individual project. The key element is defect assessment.

• Involve the Equipment Manufacturer: Only the designer knows how the shifting center of gravity of a damaged silo affects the entire row of silos. Third-party experts often only see “holes in the panels,” failing to notice micro-cracks in the stiffeners.
• “Parallel March” Scenario: If grain storage downtime costs more than the repair, spare parts are ordered simultaneously with dismantling. This is a fast but expensive route with the risk of ordering unnecessary parts.
• “Full Dismantling” Scenario: Maximum savings. Only after dismantling the silo “to the last bolt” can it be determined which parts can be used as “donors” and which need to be manufactured anew.

Bottlenecks in the Technological Chain

The most popular request for modernization is replacing an old grain dryer with a modern one (e.g., a 100% automated Brice-Baker grain dryer, which can be simultaneously connected to both a heat generator and a gas main).

But here lies a trap:

1. Capacity Balance: If the dryer starts producing 100 t/h instead of 20 t/h, can your elevators and intake pit handle it? Without modernizing the entire chain, the grain dryer will operate in an inefficient “start-stop” mode.
2. Energy Limit: Owners often find out that the gas supplier cannot provide additional gas volume only after the dryer is installed. Check technical specifications before purchasing.
3. Heat Curtain: When installing heat generators for grain dryer operation on alternative fuel, it is crucial not to place them near the air intake zone for grain cooling; otherwise, you will get an “overheated” product at the outlet.

Conveying System = The Grain Storage’s Circulatory System

Experts emphasize: “old” doesn’t always mean “bad”. If your grain conveyors have a large safety margin, sometimes replacing the gear motor with an energy-efficient one is enough.

However, if you are changing the configuration:

• Choose unified bearing units that are easily available on the market, rather than waiting months for the manufacturer.
• Implement instrumental control: vibration diagnostics allow you to replace a bearing a week before a failure, rather than when a line of trucks is waiting under the grain storage.

Furthermore, implemented automation of grain storage equipment allows for identifying the need to replace wearing parts before they fail. Software from KMZ Industries includes an equipment monitoring system, which tracks sensor readings, records parameters in a database, and displays information to the operator in a clear format. This enables stopping the mechanism if operating parameters exceed normal limits to prevent an emergency.

Minimum Checklist for Silo Longevity

A silo is a “living” structure. It breathes, expands in the sun, and deforms under the weight of 10,000 tons of grain.

• Monitoring: Every 10 years – a full technical inspection; annually – a visual inspection.
• Optics to Help: Use high-quality cameras or binoculars to inspect the joints of stiffeners at a height of 20–30 meters. Micro-cracks are better visible in photos than with the naked eye.
• The First Year of Silo Operation is Crucial: Be sure to check the tightening of wind rings and the condition of anchors after the first full loading/unloading cycle.

Grain storage modernization is not just replacing old hardware with new. It is a mathematical calculation where every step must be backed by an economic rationale. As experience shows, the winners in grain storage development projects are not those who built the largest facility, but those who made their technological chain as flexible and reliable as possible.
