Almi uses RAYCON BULK sorting system


Almi GmbH & Co in Austria uses the Sesotec X-ray Inspection System RAYCON BULK to remove contaminants from spices


  About Almi

Almi GmbH & Co whose headquarters and production site is in Oftering near Linz in Austria is one of the leading global manufacturers of high-quality spice blends and additives for sausage, ham, meat, and fish products.


Almi uses high-quality raw materials and attaches special importance to comprehensive inspection; they continuously monitor current developments in the raw material market and in production processes. There is complete production traceability and all products undergo final inspection. Numerous certificates (ISO 9001:2008, ISO 22000:2005, HACCP, IFS version 6, HALAL CONTROL e.K., organic certificate, kosher certificate, Austria certification mark, and others) confirm that Almi has a comprehensive quality management system. They already use, for contaminant detection, inductive metal detectors, magnets, and camera systems.


Almi was looking for the technologically optimum solution specifically for the removal of contamination that is optically indistinguishable from coarse spices and dried vegetables. In September 2012 Almi installed a Sesotec RAYCON BULK x-ray food sorting system. When choosing the system Almi, apart from high-precision inline detection of contaminants such as metal, glass fragments, ceramic particles, small stones, etc., were concerned that the system should be easy to use for non-technical staff, and offered a hygienic, easy-to-clean and easy-to-maintain design.

Among other reasons Almi chose Sesotec because they preferred a system supplier close to their location, and were particularly attracted to a solution "Made in Germany". They have already successfully completed several projects together with Sesotec , and were impressed that Sesotec has more than 30 years of experience in the type of sorting technology implemented in the RAYCON BULK system.



Almi uses the RAYCON BULK food sorting system to inspect incoming bulk materials and remove contaminants before they reach production.


X-ray technology is ideally suited for applications where conventional food optical sorting systems have reached their limits. When contaminants have the same colour as the good material then optical sorting will not work and additionally metal particles enclosed in products, dark stones in black pepper, stones that are coloured red by red paprika, or green glass fragments in green dried herbs, are all examples of contaminants that are invisible to optical colour sorting machines, but are detected by the RAYCON BULK system.



RAYCON BULK will consistently detect metal contaminants down to 0.6 mm, small stones, or glass fragments starting from as small as 1.0 mm. The integral reject unit comprises a series of mechanical flaps across an inspection width of 580 millimetres, to minimise the loss of good material.


The real-time operating system permits timing with millisecond accuracy, and the user interface is highly intuitive in operation. RAYCON systems requires minimum maintenance and operate at a high level of efficiency.

For Almi hygienic design of the sorting system is important and the system design permits the complete conveyor belt to be removed from the front for easy cleaning and replacement.



For Almi the RAYCON BULK offers major advantages for reliable customer protection and the reduced loss of high-quality end products.
