Kramer cell is used for the analysis of multi-particle products such as corn, olives or peas. During the test, thanks to the design of the cell, there is a combination of compression, shearing and extrusion.
During the test, 50g of canned drained corn are placed inside the Kramer cell. Firstly, the comb is aligned with the cell. Then a 50mm compression test is launch at 1mm/s. The 500N sensor is used in order to prevent any saturation. A 250N sensor can be used with softer samples.
This compression test conducts inside a Kramer cell allows us to characterize the difference in consistency between types of corn.
Maximal strength (Fmax) can be correlated to the consistence of the product. We can see that there is only a very small difference between the crispy one and the soft one. This apparatus demonstrate its ability to determine difference between two different samples.
Thanks to the TX-700 equipped with this cell, it becomes easy to compare and rank a wide variety of small and disparate food products such as corn.
