Stainless Steel VPMC SWIR Color Sorter Plastic Flakes Sorting Machine

Dual Detection, One-Step High-Precision Sorting

Unlike traditional single-dimensional sorters (color-only or material-only), this machine simultaneously captures molecular composition (material) + visual color data for each flake. It delivers unprecedented sorting accuracy and purity—ideal for high-standard scenarios like food-grade PET recycling.

Precision Separation, Maximize Recycling Value

Its core goal is to precisely remove non-PET polymers (e.g., HDPE/PP/PS) and off-color PET from PET flakes. This drastically boosts the purity of final PET bottle flakes, directly increasing product value.

The equipment’s high performance stems from two parallel, synergistic top-tier detection systems:

Premium Industrial SWIR Detection System

• Core Component: Dual-band InGaAs SWIR camera
• Working Principle: Different polymers have unique "molecular fingerprint" absorption spectra in the SWIR band—like conducting a "DNA test" for plastics. It accurately distinguishes over 7 common polymers (PET, HDPE, PP, ABS, PC, PS, PMMA, etc.).
• Stability Assurance: A dedicated air cooling system ensures the core sensor and halogen light source operate stably in high-temperature environments for long hours, maintaining consistent data accuracy.

High-Resolution RGB Color Detection System

• Core Component: High-resolution industrial color camera
• Working Principle: Paired with a high-intensity LED lighting system, it captures true color details of flakes—identifying subtle color variations (e.g., different PET bottle colors, label residues, yellowed 焦化 parts) and impurities invisible to the naked eye.
• Core Value: Beyond color sorting, it eliminates off-color contaminants, further enhancing the visual uniformity and quality grade of the final product.

Innovative Feeding System

A 2-layer vibratory feeder evenly spreads flakes into a single layer. This physically prevents misjudgment/missed detection caused by overlapping materials—laying the foundation for high-precision inspection.

Strong Environmental Adaptability

• Sealed Dust Protection: Fully sealed scanning and control enclosures block dust intrusion, protecting precision optical components.
• Integrated Dust Control System: Built-in dust removal module reduces dust in the scanning area—ensuring clear inspection visibility, lowering equipment cleaning frequency, and improving operational efficiency/stability.

Flexible Modular Architecture

Vertical frame design supports 4/6/8 channel configurations. It can be tailored to current throughput, budget, and future capacity expansion needs—balancing investment cost-effectiveness and long-term scalability.

The VPMC SWIR SorterPremium is not just a sorter—it’s a complete solution integrating cutting-edge spectral imaging, advanced mechanical engineering, and intelligent algorithms. With the dual safeguards of "material identification + color sorting," it provides plastic recyclers with a reliable tool to produce ultra-high-purity rPET (recycled PET). It directly helps customers:

• Upgrade product grades
• Increase profit margins
• Reduce operating costs
• Meet stringent environmental regulations

It is one of the core pieces of equipment for modern, intelligent recycling production lines.
