Product Overview
The 500–6,000 kg/h food-grade pet bottle washing recycling line is a complete plastic recycling system designed to process waste pet bottles into clean,high-quality pet flakes for reuse in fiber production,sheet manufacturing,strapping,packaging,and other plastic-processing applications.
The food-grade pet bottle washing line integrates bottle opening,sorting,crushing,hot washing,friction cleaning,rinsing,dewatering,drying,and automatic packing into one continuous production system.It is suitable for plastic recycling plants,waste management companies,pet bottle processing facilities,and manufacturers seeking a reliable source of recycled pet raw material.
With flexible capacity configurations from 500 kg/h to 6,000 kg/h,the food grade pet bottle recycling line can be customized according to raw-material conditions,product-quality requirements,workshop layout,and investment budget.
Main Features
1. Wide Capacity Range
- Processing capacity: 500–6,000 kg/h
- Suitable for small,medium,and large-scale plastic recycling plants
- Modular design allows production capacity to be expanded as business requirements grow
- Stable feeding and continuous operation support efficient large-volume processing
2. Food-Grade PET Flake Production
The FDA approved B2B pet bottle washing line is designed to produce high-cleanliness pet flakes with effective removal of:
- Dirt and dust
- Sand and stones
- Labels and label adhesive
- Caps and rings
- Beverage residues
- Oil and grease
- Organic contamination
- Fine particles and other foreign materials
For food-contact applications,the final product must also meet applicable local regulations and may require additional processes such as advanced sorting,melt filtration,pelletizing,solid-state polycondensation,and regulatory approval.The FDA approved rpet flakes washing line provides the essential cleaning and preparation stage for producing high-quality recycled pet feedstock.
3. Complete Recycling Process
A typical pet bottle recycling process includes:
1. Raw material feeding
2. Bale breaking or bottle opening
3. Pre-sorting
4. Label removal
5. Metal detection and removal
6. Bottle crushing
7. Pre-washing
8. Hot washing
9. Friction washing
10. Floating separation
11. Rinsing
12. Mechanical dewatering
13. Hot-air drying
14. Fine separation and quality inspection
15. Automatic weighing and packing
The process configuration can be adjusted based on the contamination level and the required quality of the finished pet flakes.
4. Efficient Label and Cap Separation
The FDA approved food grade B2B pet bottle washing line separates pet bottles from labels,caps,and rings through a combination of mechanical separation,air classification,density separation,and washing.Since pet has a different density from common cap materials such as pp and hdpe,the float-sink process helps separate pet flakes from floating plastic contaminants.
5. Hot Washing and Friction Cleaning
The hot-washing system softens and removes stubborn contaminants,including:
- Glue residue
- Beverage syrup
- Grease
- Oil
- Organic deposits
- Surface dirt
High-speed friction washers provide intensive cleaning through mechanical rubbing and water circulation Washing temperature,residence time,and chemical dosage can be adjusted according to material conditions.
6. Low Moisture Content
After washing,the flakes pass through centrifugal dewatering and thermal drying systems.The drying section reduces surface moisture and improves the quality and storage stability of the finished pet flakes.
A properly configured system can be designed to achieve low residual moisture suitable for subsequent extrusion,pelletizing,fiber spinning,or other plastic-processing operations.
7. Energy- and Water-Efficient Operation
The food safe pet bottle recycling machine can be equipped with:
- Water circulation systems
- Multi-stage water filtration
- Wastewater collection and treatment
- Heat recovery systems
- Variable-frequency drives
- Automatic water-level control
- Insulated hot-washing tanks
- Optimized pump and motor selection
These features help reduce operating costs and improve overall plant efficiency.
8. Automatic and Continuous Production
The FDA approved food grade pet bottle recycling machine uses conveyors,sensors,control cabinets,and automatic feeding systems to support continuous operation.Depending on the configuration,the system may include:
- Plc automatic control
- Touchscreen operation interface
- Motor overload protection
- Temperature monitoring
- Water-level monitoring
- Emergency stop systems
- Metal detection
- Automatic packing and weighing
The degree of automation can be selected based on labor availability,production requirements,and budget.
Typical Equipment Configuration
A complete pet bottle washing machine may include the following equipment:
Raw Material Feeding System
The feeding conveyor or bale opener transfers waste pet bottles into the washing machine.A controlled feeding system helps maintain a consistent material flow and prevents equipment overload.
Pre-Sorting Conveyor
Operators or optical sorting equipment remove unsuitable materials such as pvc bottles,metal,rubber,large stones,and heavily contaminated waste.Effective pre-sorting improves product quality and protects downstream equipment.
Label Remover
The label remover machine separates loose labels and reduces the amount of paper and adhesive entering the plastic crusher machine and washing system.This improves the cleanliness of the pet flakes and reduces water contamination.
Bottle Crusher
The pet crusher cuts whole bottles into uniform flakes.The cutting size can be adjusted according to the downstream washing and drying requirements.A heavy-duty rotor and replaceable blades support long-term operation.
Pre-Washing Unit
The pre-washer removes loose dirt,sand,and residual contents before the material enters the hot-washing section.This reduces the contamination load and helps lower hot-washing energy consumption.
Hot Washing Tank
The hot-washing tank uses heated water and suitable cleaning agents to remove oil,glue,beverage residues,and other difficult contaminants.It is typically manufactured from corrosion-resistant materials for reliable operation.
Friction Washer
The friction washer provides intensive cleaning by rubbing the pet flakes against the rotor and screen surface.It also helps remove fine dirt and remaining label particles.
Float-Sink Separation Tank
The density separation tank uses water to separate pet flakes from floating pp and hdpe caps,rings,and other lightweight materials.Proper water flow and tank design improve separation efficiency.
Rinsing Tank
Multiple rinsing stages can be added to remove detergent,suspended particles,and residual contaminants.Clean rinsing water improves the appearance and quality of the final flakes.
Centrifugal Dewatering Machine
The centrifugal dewatering unit removes most of the free water from the washed pet flakes.It also provides additional friction cleaning during the dewatering process.
Hot-Air Drying System
A hot-air pipeline or thermal drying system further reduces moisture.The drying temperature is controlled to avoid excessive heat exposure and material degradation.
Air Classifier and Fine Separator
Air separation removes lightweight materials such as labels,films,dust,and fine non-pet particles.This improves the purity of the finished flakes.
Packing System
The finished pet flakes can be packed in woven bags,jumbo bags,or automatically weighed and compressed for storage and transportation.
Suitable Applications
The recycled pet flakes produced by this FDA approved rpet bottle washing machine can be used as raw material for:
- Polyester staple fiber
- Filament yarn
- Pet strapping
- Plastic sheets
- Thermoforming products
- Injection-molded products
- Non-food packaging
- Recycled PET pellets
- Extrusion and compounding
- Further purification and bottle-to-bottle recycling processes
The final application depends on the purity,intrinsic viscosity,moisture content,color,and contamination level of the flakes.
