PET Edible Oil Bottle Flake Granulator

Product Overview

The PET edible oil bottle flake granulator is a customized low-temperature extrusion granulation machine specially developed for PET bottle flake waste. It can be tailored to meet customers’ production requirements and has no fixed price. The equipment employs a single-screw extrusion process, paired with a segmented precision temperature control system and a multi-stage vacuum degassing structure, enabling melt plasticization within a low-temperature range of 240–270°C. This minimizes PET thermal degradation, preserves the material’s characteristic viscosity, and produces high-purity PET recycled pellets after multi-stage high-precision filtration. The resulting pellets are uniform, transparent, and have stable appearance, meeting reuse requirements in spinning, injection molding, and other applications. The equipment is branded as PURUI, originates from NANTONG, and its overall performance and configuration comply with the stringent standards of high-end recycled plastics processing.

Technical Principle

This granulator operates on a single-screw extrusion principle and is compatible with various types of PET bottle flake raw materials that have been cleaned and dried. Equipped with a segmented precision temperature control system, it strictly maintains the processing temperature within the low-temperature range of 240–270°C, ensuring complete melt plasticization at this temperature. This effectively reduces thermal degradation of PET material and prevents significant loss of characteristic viscosity. Additionally, the machine features a multi-stage vacuum degassing structure that efficiently removes residual moisture and low-molecular substances, further guaranteeing the purity of the recycled pellets. After plasticization, the material passes through a multi-stage high-precision filter die with a maximum filtration accuracy of 150 mesh, thoroughly removing fine impurities. Finally, depending on customer needs, it can be configured with either water-cooled strand cutting or underwater pelletizing, ensuring that the produced pellets meet stable quality and performance standards.
