Design principle of Zongzi high pressure steam cooker

The high-pressure steamer for cooking zongzi offers several key advantages and design features:

1. **Uniform Heating**: Indirect heating through coil circulation ensures an even temperature throughout the pot.

2. **Energy Efficiency**: The broth remains in the pot during cooking, enabling continuous use and conserving energy.

3. **Safety and Insulation**: The pot's exterior is insulated to prevent heat loss and protect operators from burns.

4. **Quick-Opening Door**: The hydraulic quick-opening door design, equipped with photoelectric limiters and interlocking features, enhances safety and ease of use.

5. **Airtight Sealing**: The door is airtight and includes a viewing mirror for monitoring and replenishing broth as needed.

6. **Shared Hydraulic System**: Multiple units can share a single hydraulic station, reducing space requirements and operational costs.
