remove labels and other sundries and collect separately
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.
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 the Reactor
Intermittent cleaning and multi-stage continuous cleaning to ensure cleanliness and improve cleaning efficiency
Separate PET and PP/PE by density method
Multi-stage rinsing to remove the cleaning agent, flotation agent, impurities, etc. in the debris
Belt Weighing Device
Weighing and feeding to ensure stable feeding to avoid increasing screw torque and causing blockage of the feeding port
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.
A moderate vacuum system to ensure high-efficiency removal of volatile impurities
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
Take circulate nitrogen as a medium, heat the pellets in the reactor to perform solid phase polycondensation, and remove organic impurities through nitrogen
Purify organic impurities in nitrogen through catalytic reaction to ensure that nitrogen can be recycled.
