PET Bottle Recycling Washing Line Integrated PET Granulation and SSP for Food Grade or Fiber Industry

Our PET bottle washing line is a comprehensive solution designed to handle PET bottle recycling efficiently. The system includes a pre-shredder, hot washing unit, various sorting equipment, and a friction washer, all working together to produce high-quality PET flakes.

One of the key features is the Zig-Zag label remove machine. The C-flakes consist with a lot percentage of labels as well as caps and rings which with newly design of Zig-Zag label machine, it were able to reduce roughly around 92% of the label or removed impurity through just one machine.

Intensive hot washing machine with the ability to soak to do the low friction as well as high speed friction, it will be able to guarantee for the glue as well as the label and other impurities to be able to peel off from the surface of the bottle

Different colors of PET flakes affect the final product, In Order to guarantee the quality of PET flakes, we suggestion choose different sorter.

Choose flak sorter have a few different functions, such as color sorting , color sorting use a CCD-based camera for detection as well as we have optical sorting. For optical sorting use NIR-based (near infrared rinsing )sensor for detection, that is once the impurities are detected, we use compressed air to blow the impurity away from the mainstream

After completing the PET bottle washing process, the resulting PET flakes are of high quality and suitable for various applications, including fine-denier filament production and even food-grade materials.

And more, After the process of PET bottle washing line, the flakes will come out and then we will be introducing that to the pelletization as well as Solid State Polycondensation for food- grade application

Granulation and SSP processing

The granulation machine we design with a compactor with single screw extruder recycling machine, with such design it has a few characteristic:

1.the compactor function same as a hot dryer and crystallization, which stirring hot air drying unique pre drying technology, that is the material first in and first out principle of pre-dryer. Preheating and drying by mean off the hot air. Make the moisture and ensure the VOCs in the after process the flakes vaporize and escape more quickly.

2. It has a higher capacity for low density material as well as low consumption energy cost.

3. With compactor special design the balds to make sure keep the Viscosity not drop

Technical Parameter:

Cutting system choose underwatering cutting system which provides a round type(spherical) of pellets

When we introduce the materials to the after process and the reason behind that is because when we pelletize the pellets, the temperature will still be able to maintained at a higher 150degree centigrade, as though for this type of temperature will be easier to utilize in the after process which is SSP

A dryer and an online crystallization bed

Pre-heating is a mechanical agitation, this with the hollow-disc as well as the material touching the vessel surface creates heat to heat up the material. With this special design, we were able to reduce about 50% of energy consumption. This unite also gives a precise heat control and this will allow the material to be crystallized in this unit.

Reactor-tall silo main purpose is to keep a consistent heat as well as a low oxygen level where these two together will be able to achieve increasing in viscosity as well as reduce the contamination. The reactor also has a first in and first out mechanism and with mechanical discharge. We can assure that this will have no arch during production. Also with a purification for nitrogen circulation system as well as a heat recovering system for the pellet cooling. We were able to reduce the energy consumption for this unit. Ultimately, though all the designs, we are able to reduce the VOC as well as AA value to be under 1ppm which meets the food-grade regulation for our PET
