Crystallizer dehumidifier

Crystallizer dehumidifier designed for the plastics processing industry, this integrated crystallization and dehumidification dryer combines rapid crystallization with deep drying in one innovative system. Equipped with a low-dew-point molecular sieve dehumidification system, it simultaneously removes moisture and volatile impurities during crystallization, significantly enhancing the gloss, mechanical properties, and processing stability of plastic products. Ideal for engineering plastics (e.g., PET, PA, PBT) and highly hygroscopic materials.

Core Technologies

Simultaneous Crystallization & Dehumidification
Breaks away from traditional step-by-step processing. While heating promotes molecular alignment (crystallization), a closed-loop dehumidification system rapidly adsorbs moisture, shortening production cycles and reducing energy/time costs.
Low-Dew-Point Molecular Sieve Dehumidification
Utilizes high-performance molecular sieve adsorbents, maintaining a stable dew point of -40°C to -60°C to eliminate trace moisture, preventing defects like bubbles and silver streaks for premium-quality outputs.
Intelligent Temperature Control & Airflow Circulation
Precise temperature regulation within the crystallization range, paired with uniform hot-air circulation, ensures consistent heating and avoids localized overheating or uneven crystallization, even for heat-sensitive plastics.
Energy-Efficient Regeneration System
Auto-regenerating molecular sieve modules with waste heat recovery and smart switching reduce energy consumption by over 30% compared to conventional
