Project Overview: Building the Backbone of Instant Fresh Delivery
This landmark project involved the design, construction, and deployment of a massive, multi-region cold storage network for Dingdong Maicai, one of China’s leading fresh food e-commerce platforms. The total network spans an impressive 170,000 cubic meters across five strategic locations: a Shanghai front distribution center, a Hangzhou central warehouse (Phases I & II), a Dongguan warehouse, and a Suzhou warehouse.
The core challenge was to build a cold chain infrastructure capable of supporting Dingdong’s core business promise: delivering fresh groceries to customers’ doors within 29 minutes. This required a network of facilities designed for high-speed turnover, absolute temperature integrity, and massive, scalable storage capacity.
Solving the E-commerce Cold Chain Challenge
1. The Problem: Fragmented Supply Chain & Perishability
Fresh food e-commerce faces brutal logistics hurdles—high spoilage rates, inefficient fulfillment, and the immense pressure of last-mile delivery. Dingdong needed a unified, standardized cold chain to ensure that a watermelon in Shanghai and a pack of shrimp in Shenzhen both arrive at the customer’s door with the same “just-picked” quality.
2. The Solution: A Phased, Multi-Temperature Network
Our solution was a distributed network of three distinct temperature zones, each designed for specific product categories and workflow stages:
| Zone Type | Temperature Range | Primary Function |
|---|---|---|
| Cold Storage & Sorting Center | 0-4°C | For vegetables, dairy, meat, and fresh produce requiring immediate chilling. |
| Constant Temperature Reserve | 15-20°C | For dry goods, beverages, and heat-sensitive non-perishable items. |
| Finished Product Freezer | -18 to -23°C | For frozen meats, seafood, ice cream, and prepared frozen meals. |
This multi-zone design allows for simultaneous storage of diverse SKUs and enables an efficient, assembly-line approach to order picking.
Technical Configuration for Scale and Speed
| Component | Specification |
|---|---|
| Total Network Volume | 170,000 m³ |
| Refrigeration (>0°C Zones) | Emerson Copeland Scroll Compressor Units (chosen for high efficiency and reliability in frequent-access environments). |
| Refrigeration (<0°C Zones) | Bitzer Compressor Units (selected for robust low-temperature performance). |
| Air Coolers | Mixed supply from Zhejiang Gaoxiang, Meileke, and Kaileli, ensuring optimal airflow for rapid temperature recovery. |
| Insulation | 100mm & 120mm B1/B2 Fire-Rated Polyurethane Panels, minimizing energy loss and ensuring long-term operational savings. |
| Control System | Imported fully automated controls with mobile app monitoring, data logging, and multi-level alarms for 24/7 remote management. |
