Vertical Pelletizing Extruder (Production-Scale)

Basket extruder for large-volume pellet manufacturing

Vertical Pelletizing Extruder (Production-Scale)

The production-scale vertical pelletizing extruder is designed for large-volume manufacturing of uniform cylindrical pellets. It processes blended mixtures of powders, excipients, and wet binders into dense, consistent extrudates through a rotary extrusion mechanism. The material is evenly fed into the extrusion chamber by a rotating shaft feeder and compressed through the die plate to achieve smooth and continuous extrusion.

Features
  • Continuous and efficient operation
    Supports uninterrupted feeding, extrusion, and shaping within an integrated process, ensuring high throughput and stable production.
  • Uniform extrusion with high yield
    Maintains consistent pressure distribution for even density across extrudates, achieving a finished product rate of ≥99% and minimizing waste.
  • Low-temperature, friction-free extrusion
    Employs a rotary extrusion mechanism that prevents heat generation during processing, ideal for heat-sensitive materials such as pharmaceuticals or biological formulations. Compared with twin-screw extruders, it requires no external cooling, reduces energy use, and eliminates die plate cracking risks, simplifying maintenance and operation.
  • Safe and stable performance
    Equipped with overload protection and low-noise operation (<45 dB), ensuring operational safety and a comfortable working environment.
  • Flexible die configuration
    Offers multiple die plate sizes (Ø0.4mm-3.0mm), capable of producing uniform cylindrical extrudates from 0.5mm to 3.0mm, meeting diverse production-scale requirements.
Typical Applications

Compatible Equipment

This extruder is typically paired with a spheronizer to form a complete pelletizing system.
Granulation and Pelletizing Equipment

This extrusion equipment is designed for pharmaceutical, chemical, and food applications. It processes blended mixtures of powders, excipients, and wet binders into soft, moldable materials. Typical examples include:

  • Pharmaceuticals: soft material mixtures, pellet precursors
  • Chemicals: catalyst carriers, granular additives
  • Food: nutrient enhancers, flavoring bases
Its extrusion system is particularly suitable for continuous production of cylindrical extrudates with high uniformity.

The vertical palletizing extrusion equipment fully complies with GMP and CIP standards:

  • Design: modular structure with easy disassembly and polished internal surfaces free of dead corners
  • Material: all contact parts made of 316L stainless steel
  • Validation: DQ/IQ/OQ documentation templates provided for qualification and verification.
