Introduction to Andrographis paniculata Drying
Andrographis paniculata , a revered herb in traditional medicine, requires precise drying to preserve its active compounds like andrographolides. Traditional sun-drying methods risk contamination and inconsistent quality, while conventional thermal drying often degrades heat-sensitive bioactive components. MeiYa Air Source Heat Pump Dryers address these challenges through intelligent temperature-humidity control, ensuring pharmaceutical-grade drying outcomes while maintaining GMP compliance.
MeiYa Heat Pump Dryer Advantages
- Energy Efficiency Redefined
Utilizing reverse Carnot cycle technology, MeiYa dryers recover 85% of latent heat – consuming only 25% of the energy required by conventional dryers. Our dual-stage dehumidification system maintains optimal drying conditions even in high-humidity environments. - Precision Phytochemical Preservation
Patented PID control maintains temperatures at 35-45°C (±0.5°C) with relative humidity stabilized between 15-25%, preventing thermal degradation of bitter glycosides while achieving 12% moisture content uniformity. - Smart Automation
IoT-enabled systems automatically adjust drying parameters through 6-stage programs. Real-time moisture sensors eliminate manual sampling, reducing labor costs by 70% compared to traditional methods.
Phase-Controlled Drying Protocol
Phase 1: Pre-Treatment
- Sort leaves/stems within 2hrs post-harvest
- Initial moisture reduction to 35% using 38°C air circulation
Phase 2: Primary Drying (0-18hrs)
- Progressive temperature ramp: 40°C → 43°C
- Airflow velocity: 1.2-1.5m/s (horizontal laminar flow pattern)
- Continuous dehumidification to 20% RH
Phase 3: Final Conditioning (18-24hrs)
- Temperature stabilization at 45°C
- Moisture equilibrium control (MEC) system activation
- Final product moisture: 8-12%
Post-Processing
Automated cooling to ambient temperature before nitrogen-flushed packaging.
Performance Comparison
| Parameter | Traditional Methods | MeiYa Dryers |
|---|---|---|
| Drying Cycle | 48-72hrs | 24hrs |
| Energy Cost | $1.2/kg | $0.28/kg |
| Labor Requirement | Continuous monitoring | Fully automated |
