System Configuration and Working Process
ACERETECH PET Bottle Recycling System integrates sorting, washing, drying, pelletizing, and SSP technologies to transform post-consumer PET bottles into high-quality food-grade rPET pellets through a complete closed-loop recycling process.
1. Bale Opening & Label Removal
The recycling process starts with unpacking compressed PET bottle bales. The label removal system efficiently separates labels and lightweight contaminants from PET bottles, improving the efficiency of downstream sorting and processing.
2. Bottle Sorting & Material Preparation
Advanced sorting technologies are applied to remove non-PET materials, colored bottles, and foreign contaminants, ensuring stable feedstock quality before crushing.
3. Crushing & Multi-stage Washing System
PET bottles are crushed into flakes and processed through an advanced washing system. The combination of specially designed cold washing and hot washing technologies effectively removes surface contaminants, adhesives, organic residues, and other impurities from PET flakes.
4. Flake Drying & Advanced Sorting System
After washing, PET flakes are efficiently dried and processed through advanced sorting systems. The system separates remaining non-PET materials, lightweight contaminants, and different colored flakes through precise material and color sorting technologies, ensuring high purity, consistent quality, and stable feedstock performance for downstream pelletizing.
5. Dehumidification, Decontamination & Odor Removal System
Designed for food-grade rPET production, the advanced treatment system integrates dehumidification, decontamination, and odor removal technologies to effectively reduce residual moisture, volatile substances, contaminants, and unpleasant odors in PET flakes.
By improving flake purity and ensuring stable material conditions before extrusion, the system provides essential support for producing high-quality recycled PET pellets that meet demanding bottle-to-bottle and food-contact applications.
6. Extrusion Pelletizing System
Dried PET flakes are melted, filtered, and pelletized under controlled processing conditions. Advanced filtration and vacuum degassing technologies ensure stable melt quality and produce high-quality recycled PET pellets.
7. SSP Solid State Polycondensation System
The rPET pellets are further processed through SSP technology to increase intrinsic viscosity (IV), improve material performance, and achieve the quality requirements for food-grade recycled PET applications.
Through the complete process from waste PET bottles to food-grade rPET pellets, ACERETECH provides a reliable recycling solution.
