Roller screening, eddy current, and photoelectric sorting technology are used for three-dimensional preciseimpurity remova, removing soil, metal, mixed color bottles, and aging bottles.The high-temperature wholebottle hot washing and deep friction cleaning form a dual cleaning mechanism, thoroughly peeling off adhe.sive, ink, and surface impurities, ensuring that the cleanliness of bottle raw materials meets food gradestandards.

The melting section is equipped with a precision laser microporous filter screen, which is combined with apulse recoll device to achieve automatic cleaning and completely remove non melting impurities from themelt.

By adopting advanced solid phase polymerization technology and utilizing devolatilization technology theintrinsic viscosity of recvcled PET is increased (up to 0,82-1.0 dl/g),while simultaneously achieving deepseparation of impurities, enabling rPET pellet products to meet the food grade standards of native plastics.
