multi-head weigher stops and the operator can then intervene manually.
In the version of the ShredScan that has just been installed,
which like its predecessors was realised together with Groba, the
conveyor belt can also be put into reverse so that the affected part
of the grated cheese stream can be discharged. The first two versions
of the control process still throw the grated cheese through

the camera channel via an overhead conveyor belt; the two more
recent lines already work with a vibrating conveyor that enables
a finer and more even distribution of the product over the drop
section. Among other things, this is what Groba contributed to
the project from its experience as a supplier of grated cheese lines.
Reliable monitoring
Despite the high line output of 2,500 kg/h, the ShredScan works
so reliably that the complaint rate for grated cheese from the
Radeberg plant has dropped to almost zero. Clemens Richter,
Technical Manager of the cheese dairy: "We can rely on the Shred-
Scan around the clock in our production. Since we started using it,
I sleep better". Any foreign objects found are precisely documented:
the photo from the ShredScan is saved with date and time
information so that batch allocations can be traced in the event
of a complaint later on. The removed foreign bodies are physically
archived in accordance with the IFS standard with the corresponding
information.
Heinrichsthaler Dairy Works
Heinrichsthaler Milchwerke processes around 800,000 litres of
milk a day into cheese at its plant in Radeberg. Including boughtin
products, the total sales volume is 50,000 tons, of which about
a third is marketed as grated cheese. All cheese is portioned and
packed in-house. The range of hard and semi-hard cheeses is
marketed under both trade and own brands, and 30% is currently
exported to third countries. The 320 employees of Heinrichsthaler
Milchwerke generate a turnover of € 250 million.
