China's Fresh E-commerce Boom
The Chinese fresh food e-commerce market skyrocketed from ¥200B (2018) to ¥300B (2019), projected to hit ¥400B by 2020 with 30% YoY growth. This explosive expansion demands advanced cold chain solutions – precisely where JD Logistics' automated sorting systems shine.
JD Cold Chain Evolution
Born from JD Logistics' 2014 infrastructure initiative, JD Cold Chain became a standalone brand in 2018. The COVID-19 pandemic proved its nationwide network resilience through:
✅ Tech-driven operations (Automated sorting capacity: 4,500 units/hour)
✅ End-to-end cold chain services (-25°C to 15°C temperature control)
✅ Smart platform integration (60% lower energy consumption vs traditional systems)
Automated Sorting Workflow
1. Warehouse Discharge
Integrated conveyor belts directly transfer temperature-sealed packages (-18°C environment) from storage to sorting centers.
2. Package Separation
Automated splitter separates:
- Original packaging (20% volume) → Manual sorting lines
- Insulated containers (80% volume) → High-speed tilt-tray sorter
3. Two-Stage Sorting
| Stage | Equipment | Capacity | Accuracy |
|---|---|---|---|
| Primary | Changheng Tilt-Tray Sorter | 4,500 units/hr | ±5mm |
| Secondary | Branch Line Sorter | 2,500 units/hr | 99.98% |
4. Robotic Palletizing
6-axis robots stack containers into ISO-compliant pallets (Max load: 1,000kg) with <2mm positioning error.
5. AGV Delivery
Driverless vehicles (1-ton capacity) transport pallets to loading docks via:
- Laser navigation (±5cm positioning)
- Smart charging (Auto-dock when battery <30%)
- Collision prevention (3-layer safety protocols)
