01
The consumer PET flakes will be conveyed to the feeding hopper of the IR-safe flake system and fed into the rotary drum via the volumetric metering system.
02
The internal helix welded into the rotary drum ensures a homogeneous mass flow with a defined residence time (the first-in / first-out principle). Due to the rotation of the rotary drum and mixing elements integrated in the coils, the material is continuously mixed with simultaneous, constant surface exchange.
03
The infrared module installed above the material bed heats the material quickly and directly to a high temperature level.
04
The moisture-laden air is discharged from the rotary drum through a constant air stream. After minutes, rather than hours, the material exits the rotary drum and is available for the next process step.
05
The combination of the Infrared cleaning system with a finisher in the form of a desiccant dryer enables a further reduction of contamination, and has the added benefit of reduction to < 50 ppm of residual moisture.
Frequently Asked Questions
How does the infrared module work?
The module is installed above the material bed, heating the PET flakes quickly and directly to high temperatures for efficient processing.
What is the advantage of the rotary drum?
It ensures a homogeneous mass flow with a defined residence time and continuous material mixing via integrated elements.
How is moisture removed from the system?
Moisture-laden air is effectively discharged from the rotary drum through a constant, controlled air stream.
What is the benefit of the desiccant dryer finisher?
It provides further reduction of contamination and helps achieve residual moisture levels below 50 ppm.
Is this process time-consuming?
No, the material is processed in minutes rather than hours, significantly increasing production efficiency.
