Description

Product Overview

 

The automatic high-efficiency food grade pet bottle washing recycling line is an integrated recycling system designed to process post-consumer PET bottles and convert them into clean,high-quality PET flakes for reuse in plastic manufacturing.With configurable capacities from 500 to 6,000 kg/h,the line is suitable for small,medium,and large-scale plastic recycling operations.

 

The FDA approved rPET flakes washing line combines automated sorting,size reduction,hot and cold washing,friction cleaning,rinsing,dewatering,drying,and flake separation in one continuous production line.It is engineered for reliable operation,efficient contaminant removal,reduced water consumption,and consistent output quality.

 

When operated with appropriate process controls and validated materials,the food grade PET Bottle Washing Line can produce PET flakes suitable for demanding recycling applications,including fiber,strapping,sheet,thermoforming,and other downstream processes.Additional food-contact compliance requirements depend on the complete system design,decontamination process,input material,operating conditions,and applicable local regulations.

The system can be configured to remove common contaminants such as caps,rings,labels,adhesives,dirt,sand,beverage residue,organic matter,and other lightweight plastics.

 

4. Food-Grade-Oriented Washing Process

 

The washing section can be configured to support high-purity PET flake production through multiple cleaning stages,including:

 

- Pre-washing

- Crushing or wet granulation

- Hot washing with controlled temperature and detergent

- Hot washing helps loosen oil,grease,adhesives,and organic contamination

- Float-sink tanks separate PET from PP and PE bottle caps and closures

- Multiple rinsing stages reduce detergent and contaminant carryover

- Label and dust separation systems improve flake purity

- Optional optical sorting can further separate colors and non-PET materials

 

6. Durable Industrial Construction

 

- Heavy-duty carbon steel or stainless-steel construction,depending on the equipment section

- Wear-resistant components in high-friction areas

- Corrosion-resistant materials available for hot washing and rinsing equipment

- Reinforced shafts,bearings,blades,and screens for continuous operation

- Easy-access doors and inspection points for maintenance and cleaning

 

Typical PET Bottle Washing Process

 

A standard plant configuration may include the following stages:

 

1. Bale Breaker or Raw Material Feeding

 

Baled or loose PET bottles are introduced into the food grade PET bottle recycling line through a bale breaker,belt conveyor,or automatic feeding system.The feeding unit provides a steady and controlled material flow to the sorting section.

 

2. Manual or Automatic Pre-Sorting

 

Large contaminants,non-PET bottles,metal objects,heavily contaminated materials,and unwanted colors can be removed before crushing.Optional automatic sorting equipment can be installed for higher purity and improved labor efficiency.

 

3. Label and Cap Removal

 

A label separator removes loose labels and lightweight materials from the bottle stream.Depending on the configuration,caps and rings may be removed during the separation and washing stages.

 

4. PET Bottle Crushing

 

A heavy-duty PET crusher reduces whole bottles into uniform flakes.Consistent flake size improves washing efficiency,separation performance,and drying results.Screen size can be selected according to the required output specification.

 

5. Pre-Washing

 

The pre-washer removes loose dirt,sand,stones,beverage residues,and other surface contaminants before the material enters the intensive washing section.This helps reduce the contamination load and improves overall water and energy efficiency.

 

6. Hot Washing

 

The hot-washing tank in B2B food grade cleaning system uses heated water and,where required,an approved cleaning agent to remove difficult contaminants such as:

 

- Adhesive residue

- Oil and grease

- Beverage deposits

- Organic matter

- Fine dirt

- Surface coatings

 

Temperature,washing time,and detergent concentration can be adjusted according to the incoming material and final product requirements.

 

7. Friction Washing

 

A high-speed friction washer creates intensive mechanical cleaning action.The friction between the PET flakes,rotor,screen,and wash water helps remove stubborn dirt and residual labels.

 

8. Float-Sink Separation

 

The float-sink tank separates materials according to density:

 

- PET flakes generally sink

- PP and PE caps,rings,and floating plastics rise

- Lightweight contaminants can be skimmed and discharged

 

This stage is important for improving PET purity and reducing polyolefin contamination.

 

9. Rinsing

 

Clean-water rinsing removes residual detergent,suspended particles,and remaining contaminants.The FDA approved B2B PET bottle washing line may include single or multiple rinse tanks,depending on the required product quality and water-reuse system.

 

10. Dewatering and Drying

 

A centrifugal dewatering machine removes most surface moisture from the PET flakes.Thermal drying,hot-air drying can then reduce the final moisture content to the required level.

 

11. Air Separation and Flake Collection

 

An air classifier separates dust,labels,and lightweight particles from the PET flakes.The cleaned flakes are then conveyed to storage silos,big bags,or an automatic packing system.

 

12. Optional Color and Quality Sorting

 

For applications requiring higher purity,the food grade B2B PET bottle washing line can be equipped with:

 

- Optical color sorters

- Near-infrared material sorters

- Metal detectors

- Final flake inspection systems
