PET Bottle Washing Process

With a growing emphasis on environmental awareness, the recycling of PET bottles has never been more critical. A PET washing line is a high-throughput, high-performance recycling system, specifically designed to handle post-consumer PET bottles with caps and labels from various sources. The goal of such systems is to achieve high-purity, low-moisture, uniformly clean PET flakes.

In this article, we’ll delve into the workings of a PET washing line and how it aids us in achieving more efficient PET bottle recycling.

PET Washing Line: A Comprehensive Solution

A PET washing line encompasses multiple stages, including unpacking, pre-washing, label removal, sorting, granulating, washing and dehydrating, secondary granulating, and drying. These stages together form a comprehensive solution that can handle every part of a bottle, from the cap to the label.

Key Components of a PET Washing Line

A PET washing line is made up of various parts, each responsible for handling a specific stage of the recycling process. Here are some of the main components and their functions:

• Unpacking machine: Unpacks the tightly packed PET bottles, loosening them one by one.
• Pre-washing machine: Pre-washes the bottles with hot water to remove some contaminants.
• Label removal machine: Removes most of the labels on the bottles before shredding.
• Metal detector: Detects any metal contaminants that might be left in the bottles.
• Granulator/Shredder: Reduces the size of the material and pre-washes it.
• High-speed friction washer: Achieves good cleaning effects through the beating and spraying of blades.
• Hot wash tank/Steam washer: Washes with hot water using caustic soda to remove glue and oil.

The combination of these components ensures high purity and low moisture of the PET flakes, preparing them for the next steps in the recycling process.

Output of a PET Washing Line

Depending on the specific equipment and operating conditions, the output of a PET washing line can range between 500-600kg/h, 800-1000kg/h, 1000-1500kg/h, 1500-2000kg/h, 2000-2500kg/h, and 2500-3000kg/h. This flexibility allows PET washing lines to meet a variety of recycling needs of different scales.

Conclusion

A PET washing line provides a comprehensive, efficient solution for PET bottle recycling. With such a system, we can ensure every part of a PET bottle is utilized to its fullest while minimizing environmental impact. For those seeking to improve the efficiency of PET bottle recycling, a PET washing line is undoubtedly an option worth considering.
