Product Overview
What This Product Does
- Our PET hot washing pot serves as an essential cleaning unit within PET bottle recycling lines. It removes stubborn adhesive residues and label contaminants from PET bottle flakes by hot-water soaking paired with continuous agitation. Working at roughly 90°C, its 12 rpm slow-speed agitator keeps the material fully mixed; loosened labels float to the water surface and get discharged via the side outlet.
- The standard washing cycle lasts about 45 minutes. The system commonly uses hot water blended with around 2% sodium hydroxide and special PET cleaning powder, where chemical dosage is adjusted based on water volume and cleaning demands. This unit supports multiple heating methods including steam boiler, steam generator and electromagnetic induction heating.
Match the Machine to Your Material
Unstable Flake Purity
Single washing process cannot fully remove contaminants, resulting in inconsistent flake cleanliness.
It works well with friction washing, sink-float separation and fresh water rinsing to raise final flake quality.
High Cost for Full Line Rebuild
Customers want hot washing function but cannot afford to replace their whole existing recycling line.
This hot washing tank can be retrofitted into your current PET washing line after capacity and layout evaluation.
Limited Local Heating Options
Restricted power or steam supply makes it hard to find a compatible heating setup for recycling equipment.
Multiple heating modes are available — steam boiler, steam generator or electromagnetic heating for your site conditions.
Key Features
Built Around the Process
Efficient Glue Removal
Our hot washing process softens and strips stubborn adhesive residues from PET bottle flakes.
Stable Agitation & Label Separation
The 12 rpm low-speed agitator ensures even soaking. Loosened label scraps float and discharge through the side outlet.
Multiple Heating Choices
Support steam heating, electromagnetic induction heating and other heating solutions to match your site conditions.
Customizable Build
Tank size, capacity and heating setup can be customized to fit your specific recycling project.
