Model Accuracy & Validation
The core of this research is a robust prediction model for the entire moisture chain. It has been meticulously validated to ensure high accuracy and reliability across various production conditions and seasons.
90%
Achieved Prediction Qualification Rate
Validation across no less than 30 consecutive production batches on two lines, and evaluation across different seasons (February to April, May to July, August to October, November to January) and various grades, confirmed the model's wide applicability. The deviation range between predicted and actual dryer drum wall temperature remained within ±3°C, consistently meeting qualification criteria.
Comprehensive Data Integration
A sophisticated data acquisition and processing framework is essential for the model's success. Data from diverse sources are unified and refined to ensure high-quality inputs.

Machine Learning Algorithm Selection
Several machine learning algorithms were evaluated to find the most suitable one for predicting moisture chain dynamics, with Random Forest Regressor emerging as the optimal choice due to its superior accuracy and robustness.
| Model Name | Training Set Score | Test Set Score |
|---|---|---|
| Random Forest Regressor | 0.9755 | 0.8390 |
| MLP Regressor | 0.9076 | 0.5772 |
| Lasso | 0.5869 | 0.4711 |
| Ridge | 0.5690 | 0.5291 |
| Linear Regression | 0.5654 | 0.5479 |
The Random Forest Regressor demonstrated the highest scores across both training and test sets, indicating strong generalization ability and suitability for complex, non-linear relationships inherent in moisture prediction. This ensemble method integrates multiple decision trees, mitigating overfitting and providing high accuracy.
Intelligent Production Guidance
The developed system is not just a theoretical model; it's a practical tool designed to guide daily production, replacing manual, experience-based control with precise, data-driven insights.
Case Study: Guangzhou Cigarette Factory Implementation
At Guangzhou Cigarette Factory, this system directly addresses batch-to-batch fluctuations in inlet moisture and dryer temperature. It offers two primary prediction modes:
- Mode 1: Dryer Drum Wall Temperature Prediction: Proactively forecasts the temperature required for optimal drying outcomes.
- Mode 2: Drying Machine Inlet Moisture Prediction: Predicts the moisture content at the drying process entrance, allowing for upstream adjustments.
The system provides comprehensive data reports across all pre-drying stages, including moisture chain data, environmental conditions, weather forecasts, leaf storage times, and model predictions, all visualized through charts. This capability ensures consistency, reduces resource waste, and enhances overall product quality by achieving an inter-batch temperature range of the drying machine drum wall for the same grade within 5°C and maintaining inlet moisture stability within ±0.2%.
