Pre-WashThe pre-washing machine convert most, if not all, paper into pulp which will go with the water through the final screen. Pre-Wash on bottles can remove most dirt and contaminant efficiently and save a lot of water cost and chemical cost downstream in flakes wash; On the other side, pre-wash on the flakes, it enables flakes come out with paper and surface dirt almost free, before going to a buffer tank to be dosed into first sink-float tank for olefins separation.
Flakes WashingThe meaning of washing is take a flake, and heavily brush it with something, for a certain period of time, better if using hot water and some detergents. A caustic solution is also needed for a better removal of contaminants such as glues and oils.
Glue itself is not a contaminant but, leaving it into, makes turning the color during extrusion to brown, because melting point is a lot lower so its removal is compulsory. Washing is performed using a caustic solution plus the friction applied by a washing machine. This machine detaches the glue that is conveyed outside by means of the caustic solution continuously filtered by a filtration system kept at the desired processing temperature by a heat exchanger.
The difference between PET cold washing line and hot ...
A PET bottle washing line is a system used for cleaning and recycling PET plastic(polyethylene terephthalate) from PET bottles to PET flakes.
PET bottle washing lines are typically divided into two main types: cold washing lines and hot washing lines.
As the names suggest, the key difference between these two types of washing lines is the temperature of the water used in the washing process.
In a cold washing line, the water used is at room temperature or slightly chilled.
This has several advantages, including reduced energy consumption, reduced risk of heat damage to the bottles, and increased effectiveness at removing certain types of contaminants.
In a hot washing line, the water is heated to a high temperature by hot washer. This can be more effective at removing certain types of contaminants, such as bacteria and pathogens.
It can also help to dissolve and remove stubborn stains and residues from the bottles.

There are several important factors to consider in order to ensure that the PET bottle washing line produces high quality PET flakes:
Keep The Materials To Be Pure
Sorting bottles before entering the washing line, such as removing non-PET bottle materials
Remove the materials such as PVC bottles, plastic film, bottle caps, small pieces of metal, gravel, etc.
Our specific approach is to add a metal detector to the sorting table.
While obvious non-PET materials are manually removed, metal detectors can also detect small pieces of metals and prompt workers to pick them out.
Reduce The Impurity Content Of PET Flakes
Don't skimp on using the label scraping machine, hot washing system and Zig-Zag label remover in recycling line
Removal of labels and glue is crucial in ensuring clean PET plastic.
Invest in a high quality label scraping machine, as it can help to effectively remove the labels without damaging the PET flakes.
Hot washing system allows for a great deal of further cleaning of the PET plastic to remove glue residues from the PET plastic surface.
In the process of selling PET plastic flakes, you will easily find that PET flakes that have undergone the hot cleaning process sell for $100-200 per ton more than PET plastic flakes that have not undergone the hot cleaning process''
Reducing The Water Content Of PET Flakes
Invest in a good dewatering machine and drying system
Reliable dewatering machines can remove a significant amount of water from PET bottle flakes, reducing the weight and cost of transportation.
In addition, the moisture content of the PET raw material also affects the subsequent extrusion and pelletizing process.
If you are producing clean PET plastic flakes for extrusion and pelletizing, we recommend that the moisture content be as low as possible, not exceeding 6% at most.
High Quality PET Flake Materials Must Be Consistent In Color
Maintaining color consistency can usually be achieved by manually selecting PET bottles with consistent color into the cleaning line through a sorting platform.
When faced with large production capacity requirements of 2 or 4 tons per hour, We need to match the color sorting machine to the production line.
The color sorting machine can ensure that only PET bottles or flakes with consistent colors are sent to the washing line, and automatically remove contaminants or PET bottles or flakes with different colors.
Following these guidelines will help to ensure that your PET bottle washing line produces high quality PET flakes that fetch higher prices in the market.
