Single Screw Extruder 19/25 – Test extrusion properties

Intended use

Use the Single Screw Extruder 19/25 in combination with one of the Do-Corder ‘Plus’ or Lab-Station drives to test the extrusion properties of various materials, such as snacks, pasta, breakfast cereals, animal feed and rice at laboratory scale, so that you can optimise your recipes.

Comprehensive features and modularity for comprehensive materials analysis

The modular system construction opens up comprehensive materials analysis options. Depending on the application, you have a broad range of configuration options at your disposal: choose between the Do-Corder ‘Plus’ and/or Lab-Station drives and the measuring heads appropriate for your analysis.

This solution leaves the way open for expansion options, such as connecting a Twin Screw Extruder in combination with the Lab-Station drive and/or use of the Planetary Mixer P 600[h3].

The grooves in the cylinder interior guarantee good shearing behaviour, as well as optimum materials handling. When manufacturing pasta/noodles, the device scores extra points thanks to an additional opening near the raw materials dosing area, with which a liquid pump can be used.

The sample is inserted via a dosing opening and then extruded. During the analysis, sensors and controllers measure relevant values, such as temperature and pressure. You are presented with clear values that you can use to form a correlation between the process and the product. This enables you to set specific product characteristics and so optimise your extrudate.

The user-friendly Windows software allows operating data to be logged and for measurement results to be evaluated according to the latest standards. Online diagrams provide a quick overview of measurement data and evaluation results, even during an ongoing measurement.

The features of the program include:

  • Logging of experiment conditions
  • Description of the material being examined
  • Control and data collection
  • Representation and online printout of experimental data
  • Graphical representation of experimental data obtained
