Energy-Saving Effect Calculation
Taking a medium pneumatic rice huller with 6 tons/hour capacity as an example:
| Energy-Saving Measure | Energy Saving | Annual Electricity Cost Savings (300 days) | |----------------------|---------------|-------------------------------------------| | High-Efficiency Motor | 8% | Approx. 3,000 RMB | | Variable Frequency Speed | 5% | Approx. 1,800 RMB | | Intelligent Airflow Control | 15% | Approx. 2,000 RMB | | Process Optimization | 5% | Approx. 1,800 RMB | | Total | Approx. 25% | Approx. 8,600 RMB |
Above data is estimated; actual energy savings vary by operating conditions.
