Together with partner company SWAT
Automation, Groba has developed
the ShredSCan control system (patent
pending), which detects previously undetectable
foreign bodies and impurities
in grated cheese, thus preventing
product contamination. The system optically
inspects a falling stream of grated
cheese and can detect foreign bodies
and impurities made of plastic and
other materials from a size of 2 mm.
The cheese coming out of the grating
machine falls through a light channel
onto a conveyor belt. The camera
system is mounted directly in front
of the product stream and a contrast
plate, the detection field in the product
stream is uniformly illuminated. A
detected foreign body leads to a visual
display and an alarm signal, which
is used for an evaluation adapted to
the system, e.g. system stop. The de-
With its new MCV multi-cheese vat,
NDT is presenting what it describes
as a groundbreaking development.
The vat can produce everything
from cottage cheese to traditional
yellow cheese to vegetable substitutes
without compromise.
The MCV vat (sizes 4,000 - 20,000 l)
is supplied as standard for one
cheese category and with one cutting
format. Expansion to another
type requires a plug-in consisting of
a control unit and a "quick-change"
knife set for the respective curd format.
A new generation of the control
system creates full flexibility in
terms of filling level, stirring, cutting,
discharging while stirring, temperature
control (temp. over time
and delta T) and unlimited number
of recipes.

by the operator.
The ShredScan system has been in development
since 2018 and is already working
reliably on several production lines.
