Washing Line Process Flow

A typical plastic washing line passes material through sequential stages to achieve food-grade or industrial-grade cleanliness standards.

1 — Pre-Washing

Initial cold-water rinse tank with mechanical agitation removes loose surface contamination and labels from incoming flake.

2 — Hot Friction Wash

High-temperature friction washer (60–85°C) with detergent removes adhesives, oils, and organic contamination from plastic surfaces.

3 — Float-Sink Separation

Water-density separation tank removes PVC, rubber, and heavy contaminants from buoyant PE and PP fractions.

4 — Centrifugal Drying

Mechanical centrifuge removes bulk moisture (output: <2% moisture). Suitable for direct feed to extruder or pelletising unit.

5 — Thermal Drying

Hot-air thermal dryer reduces moisture content to <0.3% for demanding pelletising applications. Adjustable temperature 60–120°C.

6 — Dry Flake Output

Clean, dry flake discharged to silo or bulk bag station. Output quality suitable for re-extrusion, fibre spinning, or direct moulding.
