Petfood and Animal Feed Testing



 ottawa-cell  three-point-bend-rig-dog-biscuit  back-extrusion-petfood
Ottawa Cell
Used for determining the
compressibility, and therefore the
ease of chewing, of dry petfood
in a bulk compression test.
Three Point Bend Rig
This rig reveals the break point,
demonstrating hardness and
brittleness or flexibility of dog
biscuits or snack sticks.
Back Extrusion Cell
This test makes unpleasant manual
assessments obsolete by providing
an objective imitative assessment
of faecal consistency.
 cylinder-probe-petfood  kramer-shear-cell  multiple-puncture-probe-petfood
Cylinder Probes
Compression of cat food or fish
pellets tests for product hardness
or softness which may be vital to
Kramer Shear Cell
Multiple shearing tests overcome
sample variability in meat based
Multiple Puncture Probe
This probe has an averaging effect
on products of variable particulate
size or texture without the need for
very high forces to be applied.
Acoustic Emission and 
Video Playback
Allow the collection of acoustic
data during a test and the
synchronisation of force data with
video frames - of particular interest
for the testing of brittle products.
