Our complete PET bottle washing line is the ideal solution for anyone wishing to start or improve their plastic bottle recycling business. This fully automated, turnkey solution processes baled PET bottles into contamination-free PET flakes. These plastic flakes can be sold at high prices to polyester staple fibre manufacturers or can be made into pellets for the manufacture of other PET products.
While our standard PET bottle washing line is sufficient for most facilities, customised setups with additional machinery and larger capacities can be designed to suit your specific needs.
Working principles
Our turnkey PET bottle washing line consists of our range of plastic recycling machines, which are connected using various types of conveyor systems.
Unpackers: The first step in our plastic bottle cleaning line is to break up the compacted PET bales into a free-flowing stream. Once the large bales have been "broken", the bottles are free to move to the next machine.
Tumbler screen: An optional piece of equipment, the tumbler screen is a slowly rotating tunnel lined with small holes. These holes are slightly smaller than the PET bottles, so that small pieces of contamination (e.g. glass, metal, rock/dirt, paper etc.) may fall out when the PET bottles are moved to the next machine.
Wet plastic granulator: sometimes referred to as a plastic crusher, our plastic granulator cuts PET bottles into small 10-15 mm sized flakes. With a constant spray of water into the cutting chamber, this wet granulation process pre-treats and partially cleans the material before transferring it to the next machine.
Air Classifier: Air classification is a method of separating lighter materials from heavier materials. The main purpose of using an air classifier is to remove contaminants such as paper, cardboard and plastic labels from PET flakes.
Sink/float separation tanks: Using water as a medium, the floating material is separated from the sinking material. In the case of plastic bottle recycling, the PET plastic sinks while the plastic film (bottle labels) and PP/PE plastic (bottle caps) float. A screw conveyor at the bottom of the sink and float separation tank moves the PET plastic to the next machine.
Hot wash system: Hot washing PET flakes is of higher value as this process dissolves the glue (used to adhere the label to the bottle) and any remaining drinks/foodstuffs that are difficult to remove in the cold wash process. Although you can use only water in a hot water washing system, adding detergent will give better results.
Friction washer: An efficient cold water washing machine, the high speed friction washer uses friction as a mechanical way to remove any hard to remove dirt and debris from PET flakes.
Dehydrator: The first step in the drying process, our centrifugal dehydrator uses centrifugal force to remove most of the water from the PET flakes before they are fed into our thermal dryer.
Hot dryer: The PET flakes are evacuated from the dehydrator into the hot dryer, where they travel along a series of stainless steel tubes mixed with hot air. This process removes any residual moisture through dewatering. An attached cyclone mixes the PET flakes with cold air in preparation for storage in a product silo.
Product silo: storage tank for clean, dry PET flakes.
Pelletizer/Extruder: In most cases, PET flakes are used especially for the manufacture of polyester fibres. However, we do have customers who require plastic pelletizers, such as our single-screw extrusion pelletizers and twin-screw extrusion pelletizers.

Customised PET bottle recycling lines
Depending on the contaminants in the PET bottle package, additional equipment may be required, such as separation tables for manual sorting, metal detectors and removal, PVC heat separation, etc. ASG offers customised PET cleaning lines to your specifications. Let us know your requirements, including the capacity, the type of PET bottle and its packaging method and the type of contaminants you expect and let our team of specialist engineers handle the rest.
Installation packages are available and our engineers will travel to your plant to guide you through the installation process. Daily maintenance teams and operational consultants can also be arranged to ensure that your PET recycling plant runs smoothly year after year.
PET recycling line specially designed for pet bottles. The whole process includes de-baler, de-labeling, crushing, water washing, friction washing, hot washing and drying with water washing system; plasticizing, granulating and drying through the granulating system. The PLC intelligent system realizes a high degree of automation, and the entire production line only needs 3-4 people to operate. With years of recycling experience, Fangtai has not only mastered key technologies, but also improved machine designs to address specific product functions. Fangtai provides high yield and low energy consumption PET recycling solutions.
PET bottle washing line is used to mechanically separate the non-PET cap, seat bottom, label, and other impurities from the packaged PET plastic bottles, and then crushed, washed, and processed into non-polluting PET flakes, which can be made into recycled pellets for making other PET products, or sold to chemical fiber manufacturers.
Plastic shredders play a key role in plastic recycling plants and production facilities. It offers several benefits in addition to processing plastics that are used as raw materials for other products like storage containers, toys, packaging bags, and consumer electronics.
With the extensive growth of the plastic industry and the growth of the population, there is some increase in plastic products. Once the plastic product is in utilization, there is an important thing that comes here is plastic recycling.
The plastic granulating machine has a wide development space. With the continuous increase in the price of plastic chemical raw materials and the development of the economy, the world is vigorously supervising the development and transformation of the occupation of plastic granulating machines in recent years.
