Product Overview
From Collected Bottles to a Defined PET Flake Product
A PET bottle washing line prepares collected bottles for reuse as recycled flake. It brings material preparation, size reduction, washing, separation and water removal into a coordinated equipment package.
The right starting point is your input stream: loose bottles or bales, color mix, label construction and the level of non-PET material. The output target matters just as much. A fiber application and a sheet application may require different sorting and cleaning decisions.
This line produces washed flake. Any further processing, testing or approvals needed for a particular end use should be specified as part of the wider project.
Your Production Challenges
Match the Equipment to the Problem
Adhesive and residues survive a basic rinse
Review hot washing, friction cleaning and subsequent rinsing against the actual bottle contamination and buyer requirements.
Irregular flake size makes later stages harder to control
Select the crusher, screen and material feed together so the washing and drying equipment receives a more consistent particle stream.
One stage limits the whole plant
Balance the feed, wash, drying and storage capacities, with buffer points and access for routine cleaning.

Core Advantages
Coordinate the Bottle-to-Flake Process
Bottle preparation before intensive washing
Separate unwanted items early and select bale opening or pre-cleaning where the incoming collection stream requires it.
Washing stages with distinct jobs
Use each cleaning stage for a defined contaminant rather than assuming a longer line alone guarantees the required flake quality.
Matched separation and rinsing
Review density separation, transfer and rinse arrangement together so removed contaminants do not re-enter the product stream.
Accessible wear and cleaning points
Specify access to the crusher, screens, washing internals and drains for the service routine your operators will follow.
Utilities planned with the equipment
Clarify water, heating and power interfaces during layout review so missing infrastructure does not delay installation.
Flake quality tied to your market
Set measurable output acceptance criteria and identify the downstream process before finalizing the line.
Process Flow
PET Bottle Washing Process Flow
Each stage has a specific job. The final sequence is selected for your feedstock and plant layout.
- 01
Bottle Feeding
Open bales where required and meter bottles into the preparation stages.
- 02
Pre-sorting
Remove unsuitable polymers, metal and oversized foreign objects.
- 03
Label Removal
Separate loose label material before the bottle stream is further reduced.
- 04
Crushing
Reduce prepared bottles to the selected flake-size range.
- 05
Washing & Separation
Wash the flake stream and separate PET from selected cap and ring material.
- 06
Hot Washing
Treat persistent adhesive and residues where the agreed cleaning route requires it.
- 07
Rinsing & Dewatering
Rinse the flakes and remove process water for the next drying step.
- 08
Drying & Collection
Prepare flakes for inspection, storage and the agreed packing method.
The process shown is a planning route. Sorting position, wash sequence, hot-wash scope and water treatment are reviewed against bottle condition, site utilities and your output specification.
Materials & Applications
Is This Line Right for Your Material?
Water & beverage bottles
PET collection streams with known label, cap, color and contamination profiles.
Baled bottle streams
Collection-center material that needs bale opening, sorting and controlled feeding before washing.
Flake supply projects
Feedstock preparation for buyers in fiber, sheet or strapping applications, subject to their material specifications.
Who This Line Is For
Plan Around Your Business
Bottle recycling plants
Operators developing a complete bottle-to-flake process or replacing a bottleneck in an existing plant.

PET Bottle Hot Washing Project in Nigeria
- Location
- Nigeria
- Commissioned
- August 2025
- Reference capacity
- 3,000 kg/h project reference
Project requirement
A bottle recycler sought a higher-throughput hot-washing line after its previous equipment no longer met the production requirement.
Equipment configuration
A project-specific PET hot-washing route was arranged around a 12 mm flake target.
Project focus
The published reference focuses on increasing production capacity and improving the consistency of washed flakes.

Know the Parts That Keep You Running
Crusher Rotor, Blades & Screens
Match the cutter and screen specification to PET bottle feed. Agree adjustment, sharpening or replacement procedures and the initial spare screen and blade package.
Friction Washing Assembly
Confirm access to the rotor, screens, seals and discharge areas. Cleaning access helps the team inspect buildup and identify wear before it affects material transfer.
Dewatering & Control Interfaces
Review bearing and seal inspection, electrical protection, interlocks and PLC documentation for the selected equipment. Confirm component brands in the equipment schedule.

- Export packing
- Packing is selected for the equipment dimensions and transport route. Confirm corrosion protection, protected electrical cabinets, marked assemblies and the packing list before dispatch.
- Warranty & wearing parts
- Ask for the warranty period, coverage, claim procedure and wearing-parts exclusions in the sales agreement. Replacement blades, screens, seals and other consumables are quoted separately unless included.

Delivery & service scope
Shipping terms, packing, commissioning, training and the initial spare-parts package should be compared on the same basis in every quotation.
Frequently Asked Questions
Before You Choose Your Line
Does a PET washing line automatically produce food-contact material?
Food-contact suitability is a separate project requirement. It depends on input controls, decontamination and downstream processing, validation and the applicable approvals. Define this requirement before selecting the line.
How are bottle caps separated from PET flakes?
The line can include density separation after size reduction. Review cap and ring material, label construction and the required output cleanliness when selecting the separation and rinse stages.
How do I get an accurate quotation?
Send photos or a sample description of your incoming material, target capacity, desired output, local electrical supply and available floor space. Include the required delivery location and any existing machines.
Can the line fit an existing factory?
Provide a dimensioned floor plan with doors, columns, clear height, utility points and maintenance access. The process layout and connection heights can then be reviewed before the equipment schedule is finalized.
Are certification and warranty documents included?
Confirm the required documents, their scope, warranty period and service responsibilities in the quotation and sales agreement. A document for one component or project does not automatically cover every configuration.
Can I order spare parts with the line?
Request an initial spares list based on the selected machine models, material abrasiveness and operating hours. Confirm part numbers and wear limits so replacements match the installed equipment.
