**PLA Plastic Crystallizing Dehumidifying Dryer (4500KG/H)**
### **MegaDry™-PLA 4500: High-Throughput Crystallization & Drying System**
**Designed for Industrial-Scale PLA Processing**
*Capacity: 4,500 kg/hr | Dew Point: -50°C | Energy Efficiency: 0.25 kW/kg*
---
### **Core Technology Highlights**
#### **1. Dual-Stage Crystallization Reactor**
- **Pre-Crystallization Zone**:
- Infrared preheating to 80°C (±2°C) → Initiates crystal nucleation
- Residence time: 45-60 mins (adjustable via HMI)
- **Main Crystallization Zone**:
- Precision ramping to 105-110°C → Optimizes α-crystal formation
- Agitation system ensures >98% crystallinity uniformity
#### **2. Military-Grade Dehumidification**
| Component | Specification |
|-----------|---------------|
| **Desiccant Towers** | Twin-tower molecular sieve (13X type) |
| **Dew Point** | -50°C stable at 100% load |
| **Airflow** | 25,000 m³/hr (variable frequency control) |
| **Moisture Removal** | <80 ppm residual humidity |
#### **3. Energy Recovery System**
- **Heat Reclaim Technology**:
- Recovers 75% waste heat from crystallization zone → Pre-heats drying air
- Reduces energy consumption by **42%** vs. conventional systems
- **Zero-Emission Design**:
- Closed-loop N₂ purging prevents PLA oxidation (MW loss <5%)

### **Technical Specifications**
| Parameter | Value |
|-----------|-------|
| **Throughput** | 4,500 kg/hr (108 tons/day) |
| **Power Consumption** | 1,125 kW (at full load) |
| **Hopper Volume** | 15 m³ (stainless steel 316L) |
| **Thermal Uniformity** | ±1.5°C across material bed |
| **Residual Moisture** | ≤100 ppm (ISO 15512 certified) |
| **Footprint** | 12m(L) × 5m(W) × 8m(H) |
---
### **Industry-Leading Innovations**
#### ▶ **AI-Driven Process Control**
- Real-time crystallinity monitoring via **NIR spectroscopy**
- Auto-adjusts parameters based on:
```python
if PLA_MFI > 15g/10min: # High-flow grade
set_temp = 100°C
set_time = 50min
else: # High-strength grade
set_temp = 110°C
set_time = 70min
```
#### ▶ **Hydrolysis Prevention System**
- N₂ inert atmosphere (<50 ppm O₂)
- Moisture sensors trigger emergency purge if >150 ppm detected
#### ▶ **Continuous Operation Design**
- Dual-hopper switching → Zero downtime during material change
- Self-cleaning heat exchangers (prevents lactide buildup)
