Project Challenges
National reserve duty: long storage cycles and strict rotation windows
Strategic grain reserves are held for extended periods, and rotation outbound has fixed time windows and quality thresholds. Squat silos must keep grain quality stable throughout long-term storage and meet rotation standards at discharge — quality decline in storage cannot be allowed to disrupt the rotation plan.
Tanzania’s tropical heat makes grain temperature control and pest prevention non-negotiable
High temperature and humidity drive grain bulk heating, condensation and pest infestation. Mechanical aeration, circulation fumigation and grain cooling must run reliably; otherwise storage losses in long-term reserves directly undermine reserve safety and rotation economics.
Nine deep squat silos: grain condition monitoring must reach every bin and every grain layer
Nine 15,000 t squat silos deliver 135,000 t of capacity with large single-silo volumes and deep grain bulks. Monitoring a few points per bin is not enough — coverage must extend across grain layers and positions, or a localized hot spot goes undetected until the whole bin is affected.
MEC turnkey requires mechanical, electrical and control integration — not separate packages
The project adopts an MEC turnkey model, with mechanical, electrical and control systems integrated by a single responsible party. Conveying, aeration, fumigation, cooling and grain condition monitoring must share one control logic — equipment cannot run in isolation with disconnected systems.
03 / Solution
Solution: 15,000T × 9 Squat Silos + MEC Turnkey Integration
15,000T × 9 groups of squat silos
Large single-silo capacity with a moderate number of bins, suited to the scale and long-term storage needs of a national reserve. The squat silo structure supports even airflow distribution through the grain bulk; combined with mechanical aeration and grain cooling, it suits Tanzania’s tropical climate.
MEC turnkey integration
Mechanical, electrical and control systems delivered by a single responsible party. Conveying, aeration, fumigation, cooling and grain condition monitoring share one control logic, eliminating unclear equipment interfaces and disconnected systems.
Intelligent grain condition monitoring
Temperature and humidity monitoring covering every bin and different grain layers, with abnormal alarms providing the basis for aeration, fumigation and cooling operations.
System equipment
-
Mechanical aeration system, started and stopped according to in-silo grain temperature, to reduce bulk temperature -
Circulation fumigation system to control pests and reduce storage losses -
Grain cooling system for active temperature reduction in hot seasons to preserve grain quality -
Inlet and outlet conveying linking procurement intake and rotation discharge -
Electrical control and automation system for unified management of conveying, aeration, fumigation and cooling equipment -
Dust control at filling, discharge and transfer points
04 / Highlights
Technical Highlights: Squat Silos + MEC Turnkey + Green Storage Systems
Squat silos suit large-scale reserve storage and grain bulk temperature control
At 15,000 t per silo, the capacity suits long-term storage for a national reserve. The squat silo structure promotes even airflow distribution through the grain bulk; combined with mechanical aeration and grain cooling, it controls bulk temperature under Tanzania’s tropical conditions and reduces heating and condensation risk.
Mechanical aeration + circulation fumigation + grain cooling: the green storage trio
Aeration lowers grain temperature, circulation fumigation controls pests, and grain cooling actively reduces temperature in hot seasons. Used together, they reduce reliance on chemical treatments, align with green storage principles, and suit Tanzania’s hot, humid storage conditions.
Grain condition monitoring reaches the grain layers, not just a few points — and MEC turnkey runs on one control logic
Monitoring covers every bin and different grain layers, collecting real-time temperature and humidity data with abnormal alarms to guide aeration, fumigation and cooling — preventing a localized hot spot from becoming a whole-bin loss. Under MEC turnkey, mechanical, electrical and control systems are integrated by one party, with conveying, aeration, fumigation, cooling and monitoring running on the same control platform, reducing operational and maintenance issues caused by unclear interfaces.

06 / Testimonial
Client Feedback
“Nine 15,000 t squat silos plus mechanical aeration, circulation fumigation and grain cooling let us store reserve grain safely and well even under Tanzania’s heat. Grain condition monitoring reaches different grain layers, so localized heating is caught early — we no longer discover problems only at outbound. With MEC turnkey under one responsible party, conveying, aeration, fumigation and cooling run on a single control logic, making operation and maintenance far less troublesome than before. This system supports our entire chain from reserve procurement to rotation discharge.”
