Raw materials & end product of PET bottle washing plant

Raw materials

Suitable for bulk plastic bottles and compressed PET bottle bricks. Our plastic bottle washing recycling plant is also capable of compressing and baling PET bottle bricks. Our equipment is equipped with an advanced unpacking system that can efficiently unpack bottle bricks.

Final product

• Through professional cleaning processes, PET sheets achieve a high degree of cleanliness.
• After the drying process, its humidity is less than 1%. Humidity control is to ensure that the PET sheets do not get wet during subsequent processing and application and maintain stable physical properties.
• Application fields: Clean PET sheets can be widely used in various fields, such as the manufacturing of recycled PET bottles, fibers, films, sheets, injection molded products, etc.

PET bottle crushing washing plant machinery

The main machines of the PET bottle crushing washing plant are plastic bottle crushers, washing machines, and dewatering machines.

Plastic crusher: Once the plastic bottles enter the plastic crusher, there are rotating blades which cut the bottles into small pieces or fragments. In a bottle crushing machine, a screen is provided to control the size of the final plastic pieces. By selecting screens with different apertures, it is possible to produce a chip size that meets specific requirements.

Plastic washing machines: PET bottles enter the floating washing tank. Through the different densities of plastics and debris, water acts as an intermediary to separate light impurities (such as labels, caps, etc.) from heavy impurities (such as stones, metals, etc.) in the tank. Light impurities float to the surface of the water while heavy impurities are deposited at the bottom of the pool.

Hot water at 70-80 degrees Celsius in the hot wash tank heats the PET bottle flakes for cleaning. The addition of lye and high temperatures help remove more stubborn dirt and kill bacteria.

In a friction washer, PET chips are passed over rotating friction rollers. These brushes or rollers exert friction on the bottle surface, removing dirt and residue from the bottle surface.

Dewatering machines: Plastic is subjected to a rotational, centrifugal process in a plastic dewatering machine. These forms of motion can help to shake moisture out of the plastic, making it drier.

Hot washing or cold washing?

There are some factors that could influence the washing method and washing temperature.

Degree of contamination

If the contamination on the PET plastic bottle is light, such as only some light sand or residual liquid on the plastic bottle, a cold wash may be all that is needed. However, if the PET bottle is contaminated with more serious contamination, such as grease, food residue, paint and other stubborn adhesions, a hot wash tank may be required to ensure better cleaning results through hot washing and clearing at higher temperatures.

Area of PET application

The use of the PET bottle is also a consideration. For example, PET bottles used for food and beverage packaging may require higher washing standards to ensure that no harmful substances remain after recycling, a situation that requires consideration of how the plastic is washed.

Environmental requirements

Hot washing may require more energy, while cold washing is more energy efficient. In the pursuit of a more environmentally friendly and sustainable production process, some producers may prefer to utilize cold washing technology.
