water. If you have issues with plastics or
cardboard, X-rays are not as reliable, and
then you might want to go with vision systems, "
Mr. Zhao added. " But you only see
what's on the surface with vision systems, not
in di v id u a l
packages to full
case inspection with little or
no reduction in detection capabilities.

the same line, which saves equipment space and reduces
overall investment.
Hyperspectral imaging, which has been around for a
long time, has evolved as well.
" People now realize that they don't need full hyperspectral
imaging and highly complicated big computers
to do it, " Mr. Zhao said. " You can selectively pick
a few wavelengths in the area where most common
foreign materials are being found and use multispectral
imaging. "
Such imaging can check for moisture or fat, and more
easily identify a piece of white plastic sitting on mozzarella
cheese of a pizza, for example. He suggested multiple
systems provide complementary, and not necessarily
redundant, inspection protection.
" Metal detectors can only detect metal, and X-rays
can easily detect anything that's heavier than water and
have trouble detecting materials that are lighter than
what's underneath, so you might want to consider
X-rays or a metal detector as well to broaden the magnitude
of the contaminants you can find. "
Several inspection equipment companies reported
they are now employing new forms of artificial intelligence
(AI) as well as existing data management systems
to enhance inspection capabilities and efficiencies.
" Small and large bakeries are now looking into software
solutions that can help them gather and manage
various sources of data and use that information to
monitor, report and follow up on audits, recalls and/or
quality defects in production more efficiently than before, "
said Bernardo Zermeño, customer development
director, Rexfab. " Additionally, the pandemic has taught
companies in all fields that a high level of automation
can make the operations more robust toward unpredictable
shocks, like a global pandemic. "
The company, for instance, offers Mekitec's Data
Manager software, which collects data from each X-ray
system and enables quality assurance managers to verify
the completion of required audit validation tests or
monitor rejections at each X-ray system. Mr. Zermeño
said the use of data systems has increased since the pandemic
when businesses became more familiar with using
remote tools to identify areas for improvement with
food safety and quality control equipment.
