Almi uses Sesotec X-ray inspection system
The manufacturer of spice blends and additives for sausage, ham, meat and fish products has the Raycon Bulk at its production site in Oftering near Linz, Austria.
For contaminant detection they already use inductive metal detectors, magnets and camera systems.
Almi wanted to remove contamination that is optically indistinguishable from coarse spices and dried vegetables.
The firm had already completed several projects with Sesotec.
Raycon Bulk can detect metal particles enclosed in products, dark stones in black pepper, stones coloured red by red paprika or green glass fragments in green dried herbs.
It will detect metal contaminants down to 0.6mm, small stones, or glass fragments from 1mm.
The reject unit has a series of mechanical flaps across an inspection width of 580mm, to minimise the loss of good material.
