How JD Cold Chain Achieves 45,000 Orders/Day with Automated Sorting Systems (2020 Tech Breakdown)

Cold chain automated sorting system

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)
