Product Description
The PET Hot Washer Machine is an essential cleaning system in modern PET bottle recycling lines. It is specially designed to remove stubborn contaminants such as oil, glue, labels, grease, mud, and organic residues from PET flakes through high-temperature chemical washing.
Widely used in PET bottle washing plants, plastic recycling factories, and food-grade PET recycling systems, the hot washer significantly improves the cleanliness and quality of recycled PET flakes before drying and pelletizing.
At Zhangjiagang Chenxing Machinery Co., Ltd., we manufacture durable and energy-efficient PET hot washing equipment suitable for different recycling capacities and contamination levels.
A PET hot washer is a thermal cleaning machine used in PET bottle recycling systems. During the washing process, PET flakes are mixed with heated water and chemical detergents inside a stainless-steel drum.
The rotating paddles continuously stir the material, allowing PET flakes to rub against each other while dissolving glue residues, oil contamination, and dirt from the surface.
Compared with traditional washing systems, the continuous-operation hot washer offers:
Higher washing efficiency
Better cleaning consistency
Reduced reaction time
Lower water consumption
Improved production capacity
This machine is especially suitable for highly contaminated PET bottle flakes collected from post-consumer waste streams.
The PET hot washer is commonly used for:
PET bottle recycling lines
Food-grade PET flakes recycling
Mineral water bottle recycling
Beverage bottle recycling plants
PET sheet recycling systems
Polyester flakes cleaning systems
Plastic washing and recycling factories
Suitable materials include:
PET bottle flakes
PET sheet scraps
Crushed PET plastics
Post-consumer PET waste
The PET flakes enter the hot washing tank through a screw conveyor or feeding system. Inside the tank:
Water and chemical detergent are heated to a controlled temperature.
Rotary paddles continuously stir the flakes.
PET flakes rub against each other to remove surface contamination.
Oil, glue, labels, mud, and organic residues are separated.
Clean PET flakes are discharged to the next washing or rinsing stage.
The continuous-running structure ensures stable production capacity and reliable cleaning performance.
The combination of hot water and chemical washing effectively removes:
Oil residues
Adhesive glue
Labels
Grease contamination
Surface dirt and mud
Unlike traditional batch systems, this hot washer supports continuous operation for higher throughput and lower downtime.
The drum and main contact parts are made of SUS304 stainless steel for:
Corrosion resistance
Long service life
Easy maintenance
Stable operation in high-temperature environments
The rotary paddle system increases friction between PET flakes, improving washing quality without damaging materials.
Different drum diameters and motor configurations are available to match various recycling capacities.
