Optimized Andrographis paniculata (Chuanxinlian) Drying Solutions with MeiYa Heat Pump Technology​

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

1. ​​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.
2. ​​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.
3. ​​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
Color Retention	60-75%	92-95%
Andrographolide Content	2.1-2.4%	2.8-3.2%

Conclusion

MeiYa’s pharmaceutical-grade drying solutions enhance Andrographis paniculata quality while achieving 62% operational cost reduction. Our modular dryers accommodate batches from 600kg (MY-HP700 model) to 1,200kg (MY-HP1400) fresh material, with optional GACP-compliant control systems for export-grade production.
