The BACK EXTRUSION RIG (A/BE) is comprised of a sample container which is centrally located beneath a disc plunger.
The disc plunger performs a compression test which extrudes the product up and around the edge of the disc.
This test measures the consistency of viscous products, such as yoghurt, creams and sauces, processed fruit and vegetables, or moisturising creams, shampoo and hair gel products.
The 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.
