60,000T Steel Silo Group Project
National Reserve · 500 TPH Automated Handling · China · Delivered 2022
AmGrainTech delivered a 60,000T bolted flat-bottom steel silo group in China in 2022 for a national-level grain reserve institution — engineered for the Northeast's temperate monsoon humidity, with 500 TPH automated grain handling (bucket elevators + scraper + belt conveyors), centralized temperature-control ventilation and remote grain-condition monitoring.

Technology: Sealed Bolted Storage for Monsoon Humidity
China's Northeast brings a temperate monsoon climate — high humidity in the rainy season punishes leaky storage. The 60,000 t group is built on three pillars:
Bolted Assembly Sealing & Strength
The bolted assembly structure delivers excellent sealing performance and structural integrity — airtight silos that keep monsoon humidity out and ship flat for efficient transport.
500 TPH Automated Handling
Bucket elevators + scraper conveyors + belt conveyors form a 500 TPH automated line for rapid large-scale loading/unloading turnover across the multi-silo group.
Centralized Monitoring
A centralized temperature-control ventilation system with multi-point temperature sensing and remote grain-condition monitoring guarantees safe long-term storage of rice and corn.
Project Background, Challenge & Solution
Client Background: The client is a national-level grain reserve institution in China's Northeast, a major rice-producing region with steadily growing production. It needed large storage facilities to safeguard regional food security.
Challenge: The Northeast's temperate monsoon climate brings high humidity in the rainy season, imposing extreme requirements on silo airtightness and corrosion resistance — while meeting the throughput of large-scale centralized loading and unloading.
Solution: AmGrainTech provided a bolted flat-bottom steel silo multi-silo combination (60,000 t total) with 500 TPH automated grain handling (bucket elevators + scraper conveyors + belt conveyors), a centralized temperature-control ventilation system, and remote grain-condition monitoring.
Result: Delivered as a turnkey project in 2022, the group provides airtight long-term storage of rice and corn with rapid automated turnover and real-time condition visibility for the national reserve.

Why Bolted Flat-Bottom Fits National Reserve Duty
- Sealing is the first line of defense — monsoon humidity enters through bad joints; bolted assembly delivers verified airtightness at 60,000 t scale.
- Flat bottoms maximize volume — at reserve tonnages, flat-bottom silos offer the best capacity-per-dollar, with sweep systems for full discharge.
- Automation carries the turnover — 500 TPH across elevators, scrapers and belts moves reserve-scale quantities without scaling labor with them.
- Remote monitoring closes the loop — multi-point sensing plus remote grain-condition monitoring catches issues before they become losses.
Client Evidence
“A 60,000-tonne silo complex run from a single control room. Even at 500 t/h during the autumn intake peak there is no queue, and grain condition is monitored remotely in real time.”
