          ### **PET Plastic Dehumidification, Stirring & Drying System**  

          **—Integrated Solution for High-Precision Polymer Conditioning**  


          ---


          #### **Core Technology**  

          1. **Triple-Function Integration**  

            - **Dehumidification**: Dual-layer molecular sieves (4A + 13X) achieve a **-45°C dew point**, reducing moisture to **≤30 ppm** (ISO 15512 compliant).  

            - **Stirring**: 3D helical agitator with variable-speed drive (5–35 RPM) ensures uniform thermal distribution (±1.2°C variance).  

            - **Drying**: Multi-zone hot air circulation (80–160°C) optimizes crystallinity (25–50%) for downstream processing.  


          2. **Smart Process Control**  

            - Real-time monitoring via:  

              - NIR moisture sensors (±5 ppm accuracy)  

              - DSC-based crystallinity prediction algorithm  

              - IoT-enabled PLC with remote diagnostics  


          ---


          #### **System Configuration**  

          | Module | Key Components | Functionality |  

          |--------|----------------|---------------|  

          | **Pre-Treatment** | Vibratory sieve + magnetic separator | Removes fines (≤0.5mm) and metal contaminants |  

          | **Dehumidifier** | Rotor adsorption wheel (PVDF-coated) | Maintains ≤30 ppm moisture |  

          | **Stirring Chamber** | PTFE-coated blades + anti-static lining | Prevents pellet bridging |  

          | **Drying Tower** | Energy recovery heat exchanger | Reduces energy use by 35% |  


          ---


          #### **Technical Specifications**  

          | Parameter | Value |  

          |-----------|-------|  

          | Capacity | 0.5–12 tons/hour |  

          | Power Consumption | 0.15–0.28 kWh/kg |  

          | Residual Oxygen | <300 ppm (optional nitrogen purge) |  

          | Pellet Damage Rate | <0.05% |  

          | Noise Level | ≤50 dB(A) |  


          #### **Innovative Features**  

          - **Anti-Bridging Design**: Air cushion-assisted material flow prevents clogging.  

          - **Self-Cleaning Mechanism**: Automatic compressed air purge (2–10 bar adjustable).  

          - **Hybrid Heating**: Combines electric + steam heating for flexible temperature control.  


          #### **Industrial Applications**  

          1. **Bottle Preform Production**: Ensures IV drop ≤0.02 dl/g, meeting Coca-Cola PET PCR 50+ standards.  

          2. **Sheet Extrusion**: Reduces fish eyes to <3 pcs/m2 in APET/CPET sheets.  

          3. **Recycled PET (rPET)**: Processes post-consumer flakes with ≤0.3% contamination.  


          #### **Certifications & Compliance**  

          - **CE Mark** (EN 60204-1)  

          - **FDA 21 CFR §177.1630** (food-contact approval)  

          - **ISO 50001** (energy efficiency)  

          - **ATEX Zone 22** (explosion-proof option)  


          #### **Operational Benefits**  

          - **Energy Savings**: Cuts annual CO? emissions by 150+ tons (vs. conventional systems).  

          - **Quality Improvement**: Increases product yield from 88% to 98.5%.  

          - **Downtime Reduction**: Predictive maintenance alerts slash unplanned stops by 60%.  


          **Case Study**:  

          A North American PET bottle manufacturer achieved:  

          - 30% faster production line speed  

          - $220,000/year energy cost reduction  

          - ROI within 14 months  


          Globally deployed in 80+ facilities, this system guarantees ≤50 ppm moisture consistency for 99.8% of production batches.
