Mini extruder for early development phase testing
In early development, tackling limited material availability is crucial; this compact mini extruder optimizes small-batch processing, ensuring precise control for seamless transition to full-scale production.

Processes Small-Scale Extrudates for R&D Applications
The ZE 5 HMI from Three-Tec is a compact, table-top mini extruder designed for research and development applications in pharmaceuticals, biotech, and chemical industries. Its small-scale extruder capabilities make it ideal for manipulating minimal material batches, perfect for early-stage testing where resources are limited. The ZE 5 HMI features customizable co-rotating screw conveyors, designed for specific processing needs such as conveying, kneading, mixing, compacting, pressing, decompressing, or reverse conveying. This flexibility enhances its integration into R&D labs seeking precision in testing various formulations. Equipped with options for water, air, or liquid nitrogen cooling, as well as optical pressure measurement and liquid feeding, it achieves efficient and controlled processing of products like capsule fillers, vitamin gummies, and protein supplements. Automated via a touch panel interface, it fits seamlessly into laboratory environments, allowing manual or semi-automated operation as needed. Constructed from stainless steel 316L, the ZE 5 HMI ensures durability and corrosion resistance, meeting stringent industry standards for material handling and safety.
