Our complete PET bottle washing line is an ideal solution for anyone looking to start or improve their plastic bottle recycling business. This fully automated, turnkey solution processes baled PET bottles into contaminant-free PET flakes. These plastic flakes can be sold for high prices to manufacturers of polyester staple fiber or can be pelletized into granules for use in manufacturing other PET products.

While our standard PET bottle washing lines are sufficient for most facilities, custom setups with additional machinery and increased capacity can be designed for your specific needs.
Our turnkey PET bottle washing line consists of a series of our plastic recycling machines connected using various types of conveyor systems.
Debaler Machine: The first step in our plastic bottle washing line is to break the compacted bales of PET bottles into a free flowing stream. Once the bales are “busted”, the bottles can move freely onto the next machine.
Trommel: An optional piece of equipment, the trommel is a slowing rotating tunnel lined with small holes. The holes are slightly smaller than the PET bottles so small pieces of contamination (such as glass, metals, rocks/dirt, paper, etc…) can fall through while the PET bottles move onto the next machine.
Wet Plastic Granulator: Sometimes referred to as a plastic crusher, our plastic granulator machine cuts the PET bottles into small flakes between 10-15mm in size. With water constantly spraying into the cutting chamber, this wet granulation process pre-treats and partially cleans the material before moving onto the next equipment.
Air Classifier: Air classification is a way to separate lighter materials from heavier ones. The main purpose of using the air classifier is to remove contaminations such as paper, cardboard, and plastic labels away from on PET flakes.
Sink / float Separation Tank: Using water as a medium, materials that float are separated from materials that sink. In the case of plastic bottle recycling, PET plastic will sink while plastic film (bottle labels) and PP/PE plastic (bottle caps) will float. A screw conveyor at the bottom of the sink float separation tank moves the PET plastic to the next piece of equipment.
Hot Washer System: Hot washed PET flakes are of higher value because this process dissolves glues (used to glue labels onto the bottles) and leftover beverages/foods that are difficult to remove in a cold wash process. Although you can just use water in the hot washer system, adding washing agents can added for better results.
Friction Washer: A efficient piece of cold water washing equipment, the high speed friction washer uses friction as a mechanical way to remove any hard to remove dirt and debris from the PET flakes.
Contact us to discuss your requirements of bottle plastic washing line. Our experienced sales team can help you identify the options that best suit your needs.
Dewatering Machine: The first step in the drying process, our centrifugal dewatering machine uses centrifugal force to remove a large portion of water within the PET flakes before moving forward onto our thermal dryers.
Thermal Dryer: PET flakes are vacuumed out of the dewatering machine into the thermal dryer where it travels down a series of stainless steel tubes mixed with hot air. This process removes any remaining moisture by dehydration. An attached cyclone separator mixes the PET flakes with cool air preparing it for storage in the product silo.
Product Silo: A storage tank for the clean, dry PET flakes.
Pelletizer / Extruder: For the most part, PET flakes are used as is particularly in manufacturing polyester fibers. However, we do have customers requiring plastic pelletizing machines such as our single-screw extruder pelletizers and twin-screw extruder pelletizers.
Our PET washing line produces high-quality PET flakes that are clean and contamination free. Below are typical benchmarks for PET flakes produced from this recycling line:
All recycling machinery comes with a limited warranty
We offer installation packages where our engineers travel to your facility to guide your through the installation process the. Routine maintenance teams and operations consultants can also be arranged to ensure your PET recycling plant runs smoothly year and year.

Ⅲ Characteristics of plastic cleaning line
Overview
Plastic cleaning line is a general term for plastic cleaning, and is also often called waste plastic cleaning line equipment. The main purpose is to clean and recycle plastic environmental protection equipment. Plastic cleaning lines are mainly divided into two categories according to materials, one is soft plastic cleaning line equipment, and the other is hard plastic cleaning line equipment.
Soft materials include agricultural films, films, shade nets, fishing nets, PP woven bags, plastic bags, cement bags, etc., while hard materials usually include plastic housings for home appliances, plastic bottles, plastic buckets, plastic safety helmets, and computer housings. , TV plastic casings, plastic tables and stools, plastic pipes, etc. These soft and hard waste plastics can be recycled and processed, which not only saves resources but also protects the environment and increases economic value, which is of great significance.
Plastic cleaning process
There are differences in the process of processing waste plastic bottles and processing plastic films. Usually, they have different names. The processing of plastic bottles is usually called plastic bottle cleaning line, daily miscellaneous plastic crushing and cleaning line, and waste HDPE/PET bottle crushing. Cleaning line, etc.; for film processing, there are waste PE film cleaning line, waste PP woven bag cleaning line, ton bag crushing cleaning line and so on. The main process flow is as follows:
Waste PE film recycling and cleaning line process:
Feeding conveyor belt - uniform feeding - shredder with water to shred into bundles or loose woven bags, and pre-washing at the same time - screw washer 1 - conveying and cleaning - pre-washing machine - removing sediment and possible small stones Such foreign matter - screw cleaner 2 (transport and clean) - rinse sedimentation tank 1 (clean material, remove sediment and impurities) - crusher (pulverize and clean with water) - screw cleaner 3 (transport and clean) - horizontal Type friction cleaning machine 1 (cleaning materials, removing sediment and impurities) — rinsing sedimentation tank 2 further (cleaning materials, removing impurities) — horizontal friction cleaning machine 2 (cleaning materials, removing sediment and impurities) — centrifugal dehydrator ( Material dehydration) - hot air drying system (further drying) - bagging system - control electric box
Waste HDPE bottle recycling cleaning line process:
Bale opening machine (break up the compacted and packed PET bottles) - disc sorting machine (remove stones, small pieces of metal and falling bottle caps that may be contained) - manual selection platform (manually select PET bottles with different colors)-- --Metal detector (to detect the metal that may be contained in the material)-shredder (with water to break the HDPE bottle)-pre-washer (remove part of the sediment and the remaining liquid in the bottle, rub and rub the label to make it fall off)- ---Rinse sedimentation tank 1 (clean the bottle flakes, remove part of the sediment and impurities, protect the cutter of the pulverizer) - Crusher (with water to crush HDPE bottle flakes) - Spiral washing machine (transport and clean) - Rinse sedimentation tank 2 ( Wash bottle flakes, remove part of sediment and impurities) - centrifugal dehydrator (wash and dry HDPE bottle flakes) - de-labeling system (remove possible remaining labels) - bagging system - control electric box
