Dry Smokeless Granulation Demystified: Why Foshan Jiuxin Fits SME Plastic Plants



For small and medium-sized plastic recycling enterprises (SMEs), traditional wet pelletizing systems have become a major operational burden. Conventional wet extrusion relies heavily on massive water bath cooling and intense high-heat melting, resulting in toxic airborne smoke, expensive wastewater treatment overhead, and large factory floor requirements.

To meet increasingly stringent global environmental regulations and reduce utility expenses, forward-thinking recycling facilities are transitioning toward dry smokeless plastic granulation.

Foshan Jiuxin Machinery has engineered an advanced dry plastic granulator that combines low-temperature gentle extrusion with waterless air-cooling technology—delivering high-yield, non-polluting performance specifically tailored for small and medium processing plants.

The Bottlenecks of Traditional Wet Granulation Systems


Traditional wet recycling lines process plastic waste through high-shear thermal melting followed by long water cooling troughs. This outdated approach creates severe operational bottlenecks:

  • High Industrial Wastewater Discharge: Water tanks collect water-soluble inks, microplastics, and dirty residues, requiring costly in-house wastewater filtration or risking heavy municipal fines.


  • Toxic Plastic Smoke & Acrid Odor: Scorching polymers at high temperatures generates thick plastic smoke and volatile organic compounds (VOCs), making it nearly impossible to pass Environmental Impact Assessments (EIA compliance).


  • Massive Workshop Footprint: Long water cooling channels and secondary drying centrifuges take up 15–20 meters of factory length, constraining SME production capacity.


  • Moisture-Induced Pellet Defects: Incomplete drying leaves residual surface water on granules, causing air bubbles, void spots, and poor structural density in recycled resin.


Technical Breakdown: How Foshan Jiuxin Dry Smokeless Granulation Works


At Foshan Jiuxin Machinery, our dry smokeless plastic granulators redefine plastic compounding and recycling through four core technical innovations:

1. Precision Low-Temperature Extrusion (Stops Smoke at the Source)

Instead of forcing raw material to melt through extreme friction and high barrel heat, Jiuxin extruders utilize custom-engineered L/D modular screws. By gently melting PE film, PP bags, and technical scrap at strictly regulated lower temperature thresholds, the machine stops thermal oxidation and smoke generation before it starts.

2. Multi-Stage High Vacuum Degassing

To handle printed films or residual surface glue, the extended barrel features multi-stage high vacuum degassing vents. These vents aggressively pull out deep-seated moisture vapor and organic volatile fumes, guaranteeing dense, gas-free output granules.

3. Waterless Air-Cooled Die-Face Pelletizing

Filtered molten resin passes through a precision die-head and is instantly cut by high-speed rotating blades. Powerful air-cooling blowers immediately solidifies the hot pellets without using a single drop of cooling water.

4. Compact All-in-One Modular Layout

By eliminating lengthy cooling troughs, water pumps, and centrifugal dryers, the entire Jiuxin dry granulator line fits within a compact footprint of 30–45 m², saving up to 60–75% of workshop space.
