MAS DRD Dry Cleaning Machine For Waterless Plastic Cleaning

When Is DRD The Right Cleaning And Drying Route?

DRD is a candidate for pre-shredded plastic fractions with separable loose dust, sand, soil, fines, residual moisture and selected dense foreign matter. Suitability depends on material geometry, bulk density, heat sensitivity, contaminant attachment and the discharge target.
Wet washing or another process may be needed for strongly adhering, oily, sticky, organic, soluble or odorous contamination, or when the downstream specification cannot be reached by dry separation. Source segregation or direct processing may be better when contamination is avoidable or sufficiently low.

Waterless Cleaning At The DRD Stage

The DRD stage uses mechanical movement, heated airflow and dry separation without adding process water. This can avoid wash-water and wastewater-treatment equipment for suitable streams.

The technology can be used where materials cannot, should not or do not need to be washed wet. For more demanding streams, the DRD can complement a conventional washing line as a pre-cleaning or post-cleaning stage.

How the DRD Dry Cleaning Process Works

The DRD combines mechanical movement, heated airflow and staged separation to remove moisture, fines and heavy contaminants from plastic feedstock.

Feed + Rotor

Separate and expose pre-shredded material.

➔

Turbulent Air Drying

Reduce suitable moisture and loosen contamination.

➔

Fine/Heavy Separation

Remove selected fines, dust, sand and heavy particles.

➔

Optional Second Stage

Add cleaning/drying duty only when validated.

DRD Input And Output Conditions

The published DRD process schematic describes the following material conditions. Actual results depend on polymer type, particle geometry, incoming moisture, contamination and machine configuration and should be confirmed through application testing.

Single-Stage Or Two-Stage DRD Configuration

Single-Stage Cleaning And Drying

A compact configuration for simultaneous drying and removal of loose contamination. It is suitable when the material condition can be handled in one chamber or when a second fine-cleaning stage is unnecessary.

Two-Stage Cleaning And Drying

The first stage dries and cleans contaminated, moist material with heated airflow. A second chamber without heating can provide additional fine cleaning for demanding material streams.

Post-Washing Drying And Fines Removal

After wet washing, the DRD can reduce residual moisture and remove remaining fines before extrusion, improving preparation of the washed fraction for downstream processing.

Key Advantages Of DRD Dry Cleaning


Dry cleaning and drying take place without process water or wastewater treatment, reducing plant complexity for suitable material streams.


The DRD is designed for effective material preparation with comparatively low space requirements and can be integrated into new or existing lines.


Fully automated control supports straightforward operation. In batch operation, a defined moisture level can be set according to the process requirement.


Removing abrasive contaminants before extrusion helps reduce wear on screw, barrel and downstream components and can lower maintenance demand.


The technology can process films, flakes, fleece, woven bags, artificial turf, geotextiles and selected production waste in application-specific configurations.


Use the DRD as a stand-alone system, as pre-cleaning before wet washing or as drying and fine-cleaning after washing.


A robust and stable system concept is intended to keep maintenance requirements low and support reliable operation.


DRD systems are available in different diameters so the equipment can be configured around the application and required capacity.
