Texture Analysis in action: the Forward Extrusion Cell

Forward Extrusion test using the TA.XTplus Texture AnalyserThe FORWARD EXTRUSION CELL (HDP/FE*) measures the compression force required for a piston disc to extrude a product through a standard size outlet in the base of the sample container. 

The sample container can accommodate base discs with outlet diameters of 3,5,7 or 10mm diameter, their selection depending upon the consistency of the sample. 

The complete sample container is located into a centralising insert fitted into the Heavy Duty Platform and a piston disc is attached to the loadcell using a probe adapter.

Products suitable for this type of test include baking fats, sauces, pastes, gels and viscous liquids OR creams, pastes, gels and viscous liquids.
*Attachments with code prefix HDP/ must be used in conjunction with HDP/90 Heavy Duty Platform.

We can design and manufacture probes or fixtures
for the TA.XTplus texture analyser that are bespoke to your sample and its specific measurement.

Once your measurement is performed, our expertise in its graphical interpretation is unparalleled. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can also prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
