Cold Chain Benchmarks are Designed and Managed According to International Standards
Walmart South China Fresh Food Distribution Center is Walmart China's first distribution center specially designed and built according to leading international standards. At 33,700 square meters, it is the largest, multi-temperature perishable distribution center in the domestic retail industry that can store and process more than 4,000 kinds of temperature-regulated, refrigerated or frozen goods simultaneously.The South China Fresh Food Distribution Center is configured with advanced temperature-control hardware. The centralized refrigeration system is based on ammonia refrigeration, combined with other refrigerants in various temperature zones, making it highly efficient and more sustainable. Ammonia refrigeration is safer, more sustainable and about 7 times more efficient than fluorine refrigeration. The cold storage in the reservoir area is designed to control temperature variables in the receiving and delivery area by using a combination of highly sealed doors. A fast-moving insulation door and a rolling door ensure the temperature of the storage area is effectively regulated, protecting the quality of the goods and saving energy. The design of the storage area saves more than 330,000 kilowatt-hours per year.
In the transportation stage of the cold chain, Walmart requires that goods be cooled before they are loaded into temperature-regulated trucks. The pre-cooling temperature is then checked by a “transportation monitoring system” and the container is only loaded once the temperature meets the set level. All shipping vehicles that serve Walmart have devices onboard that monitor the temperature in the vehicle along the delivery route to ensure that the fresh produce is protected and arrives at the store on time.
Innovative Application to Ensure the Quality of Goods
The Walmart supply chain continuously develops and applies innovative technology to optimize its operations to better serve its customers. Walmart's China supply chain enhances data storage and analytics using the internationally advanced, cutting-edge big data platform, Data Lake, and new mobile applications. Applying a digital management platform enables supply chain managers to mobilize and visualize performance management in a more intuitive, convenient manner. In addition, Walmart China's supply chain develops standard operating procedures and employee training programs according to leading international standards, continuously improving operational efficiency through digitalization.Walmart also allocates special quality inspection personnel at the distribution center to increase compliance and safeguard the quality and safety of food products. A quality testing laboratory has been set up in the distribution center to conduct front-line inspections on issues like food legal and regulatory compliance and agricultural pesticide residues. The data from these tests is shared with all stores nationwide.
Continuous Investment to Upgrade the Supply Chain and Empower Omni-Channel Development
Walmart China's distribution network sets the bar high with its wide distribution range, strong processing capacity and quick service. In 2018, Walmart China's dry warehouses and fresh food distribution centers dispatched more than 300,000 vehicles to its stores, resulting in an annual distribution mileage of more than 80 million kilometers and daily delivery of more than 1 million boxes of goods.Opening the South China Fresh Food Distribution Center increased the cold chain storage area serving Guangdong and Guangxi to meet the ever-growing customer demand for fresh goods. Other innovations include a scattered-sorting solution that provides the flexible distribution needed by community stores, and streamlining processes to reduce inventory during trial operations, saving about 50 percent of space and improving efficiency by nearly 300%.
