Electric Heating / Steam Heating Plastic Bottle Recycling Line Pet Bottle Washing Machine

Expertly Designed Plastic Washing and Recycling machine for PET Bottle Washing line

with advanced PET bottle recycling and cleaning, ensuring the production of superior- quality recycled PET flakes. by leveraging our understanding of the unique attributes of PET bottle bales .

PET bottles that are compressed to bales or briquettes. In order to have clean flakes, the PET bottles have to pass through a complex and multi-stage several procedures.

Knowing main points to helps you in good results before choose advanced PET bottle washing machine

shredding or crushing or granulators: in this step, pre-shredding a compressed PET or briquettes directly, make sure the blades are always sharp is a top priority in PET recycling. This practice not only improves the efficiency of the granulation process but also helps to maintain the overall quality of the recycled PET flakes.

Pre-washing: The 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 water or buffer tank to be dosed into first sink-float tank for separation.

Floating washing: The 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.

Drying or Centrifugal drier : In PET recycling, effective drying of the plastic flakes is crucial for achieving high-quality results. It will remove moisture with in 5% by drying system or centrifugal drier.

Friction washing: when do PET bottle washing, it need to add the caustic soda to go in touch with the glue and detach it from the surface of bottle and, using the proper water flow carry it out caustic soda from the machine. By the friction of the rotor are making, water or caustic heats up increasing the effect of caustic and therefore decreasing the residence time needed to remove the glue. All remaining labels which are still around, are detached from PET and come loose therefore a second sink-float tank is required to complete the washing steps.

Technical Parameter:

Notice: the power and requied area have changed, it will according to the whole production line design. 

PET flakes quality reference table:

we make and design Washingplants for wet recycling of plastics consisting of cutting units / wash units / separation units / drying units) which located in zhangjiagang city china manufactures and sells complete washing lines for the recycling of plastics waste. Prior to re-pelletizing the plastic waste must be size reduced, washed and if necessary foreign materials separated.

Plastic washing lines, produce granules or flakes with a high quality even at today`s required outputs. Materials which can be recycled are for example:

industrial, agriculture, domestic, thin and stretch films

PET bottles

bottles and containers made of HDPE

tanks, bottle cases, rubbish bins

PVC window profiles, car battery cases
