What is a Flake Sorter?

The Flake Sorter Machine is an optical sorting system engineered to identify and remove polymer, color, and contamination defects from recycled plastic flakes. Integrated into PET bottle-to-bottle and polyolefin recycling lines, these machines ensure food-grade purity and consistent product quality.

Through partnerships with Bühler SORTEX, Arcler delivers fully integrated flake sorting solutions that boost recovery rates and guarantee compliance with EPR and circular-economy standards.

Working Principle of Disc Screen

Include Bühler’s PolyVision + SmartEject + ProSortX 4.0 references.
Feed: Cleaned plastic flakes are evenly distributed onto the chute.
Detection: NIR, color, and polymer sensors (PolyVision, PolyCam) analyze each flake for chemical composition, transparency, and contamination.
Classification: The system distinguishes PET from PVC, PP, PE, PS, PA, rubber, and silicone.
Ejection: SmartEject™ air valves remove impurities with millisecond precision.
Monitoring: SortControl & Bühler Insights provide live data on sorting quality and throughput.

This makes the disc screen recycling process ideal for high-capacity operations that require accuracy, reliability, and low maintenance.
