PRODUCT DESCRIPTION

Transform Post-Consumer PET Bottles into Food-Grade PET Flakes

Our PET Bottle Washing Line is a high-performance recycling solution engineered to convert post-consumer PET bottles into premium-quality recycled PET (rPET) flakes with outstanding purity and consistency. The system integrates advanced separation, hot washing, rinsing, drying, and optical sorting technologies to effectively remove labels, caps, adhesives, metals, and other contaminants. Designed for continuous industrial operation, it delivers high production efficiency, maximum material recovery, and low water and energy consumption, ensuring reliable performance with reduced operating costs.

High Automation & Reliability

Multiple Capacity Options

PROCESS OVERVIEW

Bale Opening & Pre-Screening

Compressed PET bales are separated into individual bottles and passed through a Trommel Screen to remove loose contaminants like sand, glass, and oversized debris.

→

Pre-Washing & Primary Sorting

Bottles undergo mechanical pre-washing to remove surface dirt, followed by primary sorting to eliminate PVC, metals, colored plastics, and foreign objects.

→

Delabeling & Granulation

A dedicated system efficiently separates labels and adhesives. After secondary inspection, a heavy-duty Crusher reduces the bottles into uniformly sized flakes.

→

Density Separation & Hot Washing

Floating tanks remove lightweight PP/PE caps and rings. Flakes then undergo intensive hot washing with chemical dosing to eliminate glue, oils, and stubborn impurities.

→

Rinsing & High-Speed Drying

Multiple rinsing tanks eliminate detergent residues, while centrifugal spin dryers and pneumatic systems efficiently remove excess water to reduce thermal energy demand.

→

Final Sorting & Packaging

Air separators remove fine dust, while advanced optical sorters ensure high-precision color separation. The finished food-grade PET flakes are then collected in a silo for packaging.

PROCESS STAGES

#	Stage	Process	Description	Machines Involved
1	Material Feeding & Initial Preparation	Bale Opening & Pre-Screening	Compressed PET bottle bales are broken apart and oversized debris, dust, sand, and loose contaminants are removed to prepare the bottles for washing.	Bale Breaker → Trommel
2	Pre-Washing & Primary Sorting	Initial Cleaning & Contaminant Removal	Bottles are conveyed, pre-washed to remove surface dirt, and sorted to eliminate non-PET materials and visible contaminants.	Twin Screw → Pre Washer → Sorting Belt
3	Label Removal & Size Reduction	Delabeling, Inspection & Flake Production	Labels are removed, bottles are re-inspected for contaminants, and then crushed into PET flakes for efficient washing.	Label Remover → Sorting Belt → Crusher
4	Intensive Washing & Drying	Flake Washing, Separation & Rinsing	PET flakes undergo density separation, hot washing, multiple rinsing stages, and intermediate drying to remove glue, dirt, labels, organic residues, and other impurities.	Floating Tank → Spin Dryer → Hot Washer → Spin Dryer → Rinsing Tank → Spin Dryer → Rinsing Tank → Spin Dryer
5	Final Drying & Purification	Moisture Removal & Flake Purification	Remaining moisture, dust, fines, and lightweight contaminants are removed to produce clean, dry PET flakes.	Pneumatic Drying System → Zig Zag Separator
6	Quality Inspection & Packaging	Quality Sorting & Storage	PET flakes are optically sorted by color to ensure product quality and then transferred to a storage silo for packaging or dispatch.	PET Flake Color Sorter → Packaging Silo
