In November 2022, Xinguangzheng delivered a 150x80x13m steel structure dairy cold chain facility located in Kampala, Uganda, designed specifically for agricultural supply chain solutions. This facility adapts to Uganda’s tropical climate and dairy demands, achieving efficient refrigeration design and sustainable milk source protection systems.
Customer Demand
Our client is a Ugandan dairy processing cooperative, primarily handling large volumes of products such as milk, cheese, and yogurt, headquartered in the Kampala plateau district. With the momentum of East African dairy growth, the client’s cold chain needs have expanded rapidly: existing facilities struggle to handle pasture seasonal peaks and product diversity. Meanwhile, Uganda’s geographical factors exacerbate challenges, including humid plateaus with an average annual humidity of 80%, risks of bacterial proliferation, and regional earthquake and heavy rain hazards.
Through multiple communication analyses, the Xinguangzheng team proposed a customized cold storage solution:
- Large-capacity dairy anchoring: Covering at least 12000 square meters, supporting graded refrigeration and automated packaging areas.
- Swift pasture delivery: Project limited to within 7 months to match dairy peak seasons.
- Plateau ecological protection: Structure moisture-proof and earthquake-resistant, incorporating antibacterial measures to reduce contamination rates by 50-60%.
- Supply chain streamlining: Configuration allows for later dairy expansions, such as adding fermentation laboratories or wastewater treatment.
Solutions
Xinguangzheng focuses on sanitary metal protection and plateau integration for the dairy project. The facility adopts a professional steel structure system, with all components prefabricated in the factory, complying with ISO 9001 and Ugandan regulations (including UNBS standards). This process enhances insulation and on-site hygiene, reducing rainy season interference.
Core Specifications Detailed:
-
Dimensions and layout: 150 meters long, 80 meters wide, 13 meters high (arch height), total area 12000 square meters. Column-free streamlined space, facilitating refrigeration zoning and tanker flow paths.
-
Structural Components:
- Frame: Q355B pastoral-grade steel beams, load capacity 50 kN/m², adapting to dairy heavy loads and humidity stability.
- Roof and cladding: 0.8mm antibacterial sandwich panels, R-value 5.2, resisting plateau wet rain fluctuations (22°C in winter to 34°C in summer).
- Foundation: Flexible rain-resistant chassis system, suitable for plateau deployment, facilitating drainage recycling and reuse.
-
Custom Functions:
- Sanitary docking area: Supporting 30-ton milk trucks and robotic packaging operations.
- Built-in steam barrier and solar-assisted cooling: Maintaining product purity.
- 600 square meters operation layer: For quality tracking and distribution management.
Implementation Process
The facility was advanced in three phases, with a total duration of 6-7 months. We prefabricated components in specialized workshops in China, then transported them by land to the Uganda site for assembly.
- Prefabrication phase (2 months): Fine assembly in Chinese factories, reducing contamination losses by 50% through strict inspection mechanisms. Each component underwent simulated hot and humid environment testing.
- Site preparation (18 days): For the plateau, rain-proof foundation solidification and chassis engineering. Immediate integration after containers arrived, seamless Chinese export connection.
- Assembly and testing (3 months): Swift bolting installation, no welding interference. After deploying the cooling system, rainy season simulated hygiene.
For plateau wet rain, we adopted steam protective layers. Additionally, it is recommended to reserve 17% of the dairy project budget for solar optimization to prevent later chain repairs.
Results
After the facility became operational in November 2022, according to dairy monitoring and supply chain data, the steel structure building demonstrated the following advantages:
- Product quality preservation: Layered refrigeration maintains stable 2-4°C, significantly extending shelf life by 45%, initial reports show bacterial contamination rates decreased by 25-30%, supporting high-end EU exports.
- Structural adaptation: During Uganda’s rainy season, the facility withstood floods without damage, thanks to earthquake-resistant chassis and antibacterial layers, ensuring long-term purity stability of over 55 years.
- Logistics enhancement: Large-span design optimizes bottling efficiency by 38%, data shows accelerated distribution speeds, supporting smallholder scaling.
- Green impact: Wastewater treatment and energy-saving evaporation reduce environmental load by 35%, complying with Ugandan agricultural policies.
These data are derived from project audits and client feedback. Xinguangzheng offers professional dairy cold storage building construction options. For customized design, please contact our team.
Sarah Nakato, Cooperative Manager: Xinguangzheng’s facility has completely transformed our dairy operations. The moisture-proof design protected the milk sources, and the 7-month installation met the company’s development needs. Efficiency increased by 50%—super suitable for Uganda’s plateau environment!
