Dingdong Maicai Case Study—Dough Divider & Rounder by Henghao Machinery

Client Background

Dingdong Maicai is a leading fresh food e-commerce platform in China, known for its 29-minute delivery promise.
As demand for ready-to-cook foods continues to grow, products such as Shengzhou-style fresh meat xiaolongbao have become top sellers. To support large-scale, standardized production, Dingdong Maicai established central food processing facilities and sought reliable automated dough processing equipment.

Challenges

• Low efficiency: Manual dough dividing and rounding produced fewer than 2,000 pieces/hour with inconsistent weight and shape.

• Quality instability: Variations in dough size and roundness affected fermentation, steaming quality, and food safety consistency.

• Limited flexibility: Multiple SKUs required fast changeovers and adaptability to different dough types.

Henghao Solution

Henghao Machinery delivered a customized Dough Divider & Rounder solution featuring:

• High-precision dividing from 15 to 100 g, with deviation controlled within ±1 g

• Integrated dividing & rounding design for smooth dough surface and uniform structure

• Quick-change molds and recipe memory, enabling rapid product switching

• Seamless integration with proofing, forming, steaming, and quick-freezing systems

Application & Workflow

The solution is deployed in Dingdong Maicai’s central kitchen frozen dim sum line, producing xiaolongbao and other dough-based products.

Process Flow:
Dough pre-processing → Precision dividing & rounding → Automatic filling & forming → Proofing & steaming → Cooling & quick freezing → Sorting & packaging

Daily output exceeds 50,000 pieces, fully supporting peak-order demand.

Results

• Efficiency +300%: Output increased to 6,000 pieces/hour

• Quality consistency: Finished product qualification rate reached 98%

• Cost reduction: Labor demand reduced by 60%, waste rate dropped from 15% to 3%

• Flexible production: Changeover completed within 30 minutes, accelerating new product launches

Conclusion

By implementing Henghao’s automated dough divider and rounder, Dingdong Maicai successfully achieved scalable capacity, stable quality, and flexible production.
This project demonstrates how intelligent food processing equipment can empower fresh food e-commerce platforms to meet high-volume demand while maintaining premium product standards.
