How BSI+ detects the tiniest pinhole damage in almonds

The most frustrating challenges for almond producers lie around detecting the tiniest defects and removing these nuts from production. Many inspection systems simply are not sensitive enough to spot the tiniest pinhole damage, making rework by human inspectors unavoidable.

How BSI+ Technology detects tiny embedded almond shell fragments

Fragments of shell becoming embedded in almond flesh is an unavoidable effect of the shelling process. Some types of almonds are more prone than others due to water content of the nut and hardness of shell.  Unfortunately for processors, embedded shell is classified as foreign material.  With confectionary companies demanding less and less foreign material, embedded shell has become one of the most focused on defects to remove.  Many confectionary companies require less than 5 pieces of foreign material per ton.  To put this into perspective, there are approximately 1 Million almonds in one metric ton, so to ask for less than 5 pieces to have embedded shell is an enormous request.
