This recently updated, advanced continuous hot washer system offers unparalleled efficiency and cleaning abilities for PET flakes, HDPE flakes and other plastic regrinds. Traditional hot washing systems are operated by batch making it slow and difficult to calculate the washer’s capacity. Our newly improved system operates continuously and extremely effective at removing oils and other stubborn contaminants from heavily soiled plastic streams with just a single wash cycle.
WORKING PRINCIPLE
Plastic flakes or regrinds are stored in the hot washing tanks where they are mixed within a hot chemical bath where contaminants are partially dissolved and loosened. The specially designed rotary paddles inside spins at high speeds forcing the plastic pieces to rub against each. The friction generated helps with removing any leftover dirt on the surface including glue, mud, oil, and more.
To further improve upon the quality of your final product, attach a cold washing system directly after the hot washer.

Frequently Asked Questions
How does the continuous hot washer clean plastic flakes?
Plastic flakes or regrinds are stored in hot washing tanks and mixed within a hot chemical bath, where contaminants are partially dissolved and loosened. Specially designed rotary paddles spin at high speeds, forcing the plastic pieces to rub against each other — the resulting friction removes leftover dirt from the surface, including glue, mud, and oil.
What materials can it process?
The system handles PET flakes, HDPE flakes, and other plastic regrinds. It is especially effective on heavily soiled plastic streams, removing oils and stubborn contaminants with just a single wash cycle.
How is continuous operation better than batch hot washing?
Traditional hot washers operate in batches, which is slow and makes it difficult to calculate the washer’s capacity. The continuous system feeds material through without stopping between cycles, delivering steady throughput and consistent cleaning quality — a major advantage for high-volume recycling lines.
What are the technical specifications?
Mixer motor power comes in 7.5 kW, 11 kW, and 15 kW options with drum diameters of 1500 mm, 1800 mm, and 2000 mm respectively. The unit is built from SUS304 stainless steel, and the rotary valve runs at 50 RPM. CE certification is available, and larger, more powerful models can be built on request.
What should follow the hot washer in the line?
To further improve final product quality, attach a cold washing system directly after the hot washer. The cold rinse removes residual chemicals and loosened contaminants before the flakes move on to dewatering and drying.
What contaminants does it remove?
The combination of hot chemical bath and high-speed mechanical rubbing removes oils, glue residues, mud, and other stubborn surface contaminants — even from heavily soiled streams — in a single wash cycle, raising flake purity for downstream processing.
