tection and removal of mycotoxin contaminated
wheat and provides flexibility
in processed wheat. The system creates
a division between the heavy and light
fractions to concentrate potential contaminated
kernels.
Machines in the system include color
sorters, infestation destroyers, high efficiency
scourers and tempering water
purification. The color sorter allows for
the separation of contaminated kernels by
size, shape and color shade, which can be
set for the whole kernel or just for the defect.
The machine can be easily integrated
with new AI concepts, Galli said.

Domenico Felice, researcher at the Management
Engineering Department of the Polytechnic University
of Milan, discussed the ability to use AI to detect
drought stress in wheat roots.
Wheat cleaning systems
The second day focused on " The World Granary and its
Changes, " with speakers examining global challenges
for wheat production, the impacts of international unrest
on grain trade and alternative
cereal options. Marco Galli, technological
department director of Ocrim,
concluded the presentations with an
overview of Ocrim's wheat cleaning
systems.
The milling industry is faced with a
series of challenges, including market
globalization, market fluctuation, crop
quality, availability and food safety,
Galli said. Consumers are more sensitive
to food safety concerns, regulations
are tighter, contaminant limits
are reduced and there are advanced
tests for monitoring, controlling and
preventing contaminants in food.

Antolini, left,
chief executive
officer of
Ocrim, shares
a moment on
stage with
brother Sergio
Antolini, right,
president of
Ocrim.
This leads to higher attention to chemical and biological
contaminants and higher attention to the quality
of investments, Galli said. Mycotoxin contamination
presents a particular challenge because not all contaminated
wheat has the same characteristics or requires the
same separation process, he said.
" There is no single machine on the market today
that can identify directly the mycotoxin-contaminated
wheat, " Galli said. " The separation must be done indirectly.
This means that the separation must take place
through a process, not through a single machine. "
A high-efficiency cleaning system maximizes de56
processing
of large amounts of data images to make predictions
with high precision. The software uses the database
of images as a reference to detect impurities and
defects, looking at color and shadows, size and shape of
the grain and the defect, surface and density.
Infestation destroyers are an important step because
of the negative impact of insect-damaged kernels on
the rheological flour qualities, Galli said. It could lead
to cross contamination and infestation, and the flour
produced from infested wheat has a shorter shelf life.
The destroyer is positioned on the light fraction and
breaks the infected kernels against the static corrugated
surface. It is combined with an open channel aspirator
to ensure removal of the various fractions and avoid
cross contamination.
The high efficiency scourer is designed to reduce the
kernel's surface contamination and features a screen
with a high abrasion surface. It reduces ash, heavy
metal and pesticides, Galli said.
Tempering is essential for grinding, but it is also one
of the most critical phases regarding microbiological
contamination. Water and temperature are ideal conditions
for the development of contaminants, he said.
Using purified water is one solution, but this is not always
sufficient and may not apply to all countries.
" This is why further purification phases are applied
and the most common method is the use of chlorine, "
Galli said. " On the other hand, the use of chlorine is
increasingly restricted. "
Ocrim has decided to apply UV technology, using
a defined wavelength to destroy the molecular bonds
of the DNA of microorganisms. It is easy to install
and maintain, it does not subject the plant to corrosion
risks, has no flow rate limits and does not use chemicals,
Galli said.
