PET結(jié)晶干燥機PET crystallization dryer，PET干燥機

**PET結(jié)晶干燥機 / PET Crystallization Dryer**  
**概述 / Overview**  
PET結(jié)晶干燥機是專為聚對苯二甲酸乙二醇酯（PET）原料設(shè)計的集成化處理設(shè)備，通過精準(zhǔn)控制結(jié)晶與干燥工藝，提升PET顆粒的結(jié)晶度并深度去除水分，確保后續(xù)加工（如注塑、吹瓶、紡絲）的穩(wěn)定性和成品質(zhì)量。該設(shè)備廣泛應(yīng)用于飲料瓶坯、薄膜、纖維等高附加值PET制品的生產(chǎn)，尤其適用于再生PET（rPET）的高效回收利用。  
*The PET Crystallization Dryer is a specialized integrated unit designed for polyethylene terephthalate (PET) materials. By precisely controlling crystallization and drying processes, it enhances PET pellet crystallinity and achieves ultra-low moisture content, ensuring stability in downstream processing (e.g., injection molding, blow molding, spinning) and final product quality. It is widely used in high-value PET production, including beverage preforms, films, fibers, and recycled PET (rPET) processing.*  
**核心功能與優(yōu)勢 / Core Features & Advantages**  
1. **分階段工藝控制 / Multi-Stage Process Control**  
   - **預(yù)結(jié)晶階段**: 低溫勻速加熱（120-150°C），消除PET顆粒粘連風(fēng)險，初步提升結(jié)晶度至30%-35%。  
   - **深度干燥階段**: 高溫低濕環(huán)境（160-180°C，露點≤-40°C），將含水率降至≤30 ppm，同時結(jié)晶度達(dá)45%以上。  
   - *Pre-crystallization: Low-temperature heating (120-150°C) prevents pellet agglomeration and initiates crystallinity (30%-35%).*  
   - *Deep Drying: High-temperature dry air (160-180°C, dew point ≤-40°C) reduces moisture to ≤30 ppm and crystallinity to ≥45%.*
