Basket extruder for pilot-scale pellet production

The laboratory-scale vertical pelletizing extruder is designed for R&D environments and pilot-scale production. Compact, lightweight, and easy to operate, it efficiently transforms wet, cohesive mixtures of powders, excipients, and binders into uniform cylindrical extrudates. Material is fed by a rotating shaft feeder into the extrusion chamber, where it is compressed through a perforated die plate to form consistent, dense pellets.

Features

Continuous and efficient operation
Enables continuous feeding, extrusion, and shaping in one process, improving productivity and ensuring uniform output.
Uniform extrusion with high yield
Ensures consistent pressure distribution across materials, producing dense, evenly shaped extrudates with yields above 99%, minimizing material loss.
Low-temperature, friction-free extrusion
Utilizes a rotary extrusion mechanism rather than screw-based friction, preventing heat buildup during operation. Ideal for heat-sensitive materials such as pharmaceuticals or biological formulations. Unlike twin-screw extruders, it requires no cooling system, reduces energy consumption, and eliminates die plate cracking risks.
Stable and safe operation
Integrated overload protection ensures reliable performance and low operational noise (<45 dB), creating a safer and more comfortable working environment.
Flexible die configuration
Equipped with multiple die plate sizes (Ø0.4mm–3.0mm), capable of producing cylindrical extrudates from 0.5mm to 3.0mm, meeting both laboratory and small-scale production needs.
Compact and user-friendly design
The small footprint and simple control system make it ideal for laboratories, universities, and research institutes performing formulation trials and scale-up studies.

Typical Applications

Effect after extrusion
Extrusion effect of herbal extract powder blended with microcrystalline cellulose and lactose
