Sorting unit
Label Removal
remove labels and other sundries and collect separately
Automatic Sorting
Recognize bottles through near-infrared spectroscopy analysis technology, high-speed CCR camera recognition and metal sensing technology to remove impurities such as the variegated, non-PET and metal, etc.
Manual Sorting
The impurities missed by automatic sorting are removed by manual inspection to ensure that high-purity PET bottles are obtained to start the next process.
Cleaning unit
Cleaning the Reactor
Intermittent cleaning and multi-stage continuous cleaning to ensure cleanliness and improve cleaning efficiency
Flotation Reactor
Separate PET and PP/PE by density method
Rinse Reactor
Multi-stage rinsing to remove the cleaning agent, flotation agent, impurities, etc. in the debris
Extrusion unit
Belt Weighing Device
Weighing and feeding to ensure stable feeding to avoid increasing screw torque and causing blockage of the feeding port
Extruder
Automatically control the balance of screw speed and torque to minimize PET degradation. The ring-shaped screw structure allows water to be discharged in a short time and reduces hydrolysis factors.
Vacuum System
A moderate vacuum system to ensure high-efficiency removal of volatile impurities
Melt Filter
The high-precision filter screen removes small solid impurities, and the automatic rotating backwash filter ensures continuous work during the screen replacement.
Solid phase viscosity increasing unit
Reactor
Take circulate nitrogen as a medium, heat the pellets in the reactor to perform solid phase polycondensation, and remove organic impurities through nitrogen
Catalytic reactor
Purify organic impurities in nitrogen through catalytic reaction to ensure that nitrogen can be recycled.
