Multiple Puncture Probe
This probe quantifies the firmness and
hardness of products such as ‘thick cut’
marmalades or ice cream that contain
particulates. For example, these can be
meringue pieces, chocolate chips or fruit
chunks. These products can be difficult to
measure as the number, size, shape and
distribution of particulates is usually random
within each container.
While it is relatively easy to quantify the
firmness of a homogeneous sample using
standard penetration probes this method is
extremely difficult when the sample contains
particulates. A standard penetration test on
such a non-uniform product is expected to
have low reproducibility.
The use of a Multiple Puncture Probe
that penetrates the sample in several regions
serves to create an averaging effect and is
therefore usually more repeatable
This rig measures the force to
simultaneously penetrate up to 18 samples.
The insert has 18 indentations surrounding
a cone which allows the samples to easily
locate into the test positions. Puncture
strength and penetration force are
measured and the penetration distance set
so that the probes penetrate completely
through the sample.
Other applications using this rig include
beans and confectionery samples.
This rig measures the force obtained by the
penetration of a multiple sample of chips
(known in some countries as French fries). Up
to 10 chips can be tested at any one time and
the rig ensures that each chip is completely
penetrated by a 2mm diameter probe.
The probe head has a fast release
adapter to enable the probe to be rapidly
cleaned and relocated in the same position
and has three detent positions to allow
testing at three locations along the sample
lengths. Two adjustable stainless steel rods
are used to hold the samples in position on
the sample holder.
