Single Screw Extruder 19/25
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.

    Principle

    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.
