SMART PRODUCTION

The Overall Equipment Effectiveness on the equipment, machines, and
(OEE) is generally known as a quality services from the sellers who are
diagnostic tool. It is sometimes knowledgeable in their products
and can provide excellent after-sale
considered, yet equivocally, as one of services will help control and
the factors that may compromise the enhance the OEE in a constant
production capacity. In reality, a good manner. Additionally, a good device
or equipment should have features
quality monitoring device can boost that allow users to check operational
the manufacturing capacity, enhance information at any time so that the
the quality control processes, and retrieved data can be used for
further analysis, which can
ultimately help achieve optimum contribute to future improvement or
standards. prevention of any situations that
may affect the OEE.
In the food manufacturing industry, a metal
detector is undeniably indispensable. If such
device is inefficient or has unsuitable qualities,
there will be direct negative impacts on the
overall quality and production.

How Does a Metal Detector Affect
OEE?
As seen in the aforementioned table 1., there
are many circumstances that can influence
OEE. With the help of the modern technology,
however, such undesirable events can be
prevented.
A self-reliant effectiveness monitoring
technology, with indicators that inform users of
its operational status or warn them of possible
problems, will help reduce any unnecessary
disruptions of the production lines.
Frequent disruptions of the manufacturing
processes due to routine performance
monitoring of metal detectors are one of the
causes that dramatically impact the OEE. With
the help of the modern-day technology and
software, a machine’s effectiveness can be
checked and confirmed while the frequency of
the disruptive routine performance monitoring
can be lessened. Besides, the shortened
duration of such monitoring activities is also
another beneficial factor that helps improve the
overall effectiveness of metal detectors. Such
technology, which is known as the Auto Test,
involves additional accessories installed on
metal detectors and can cut down the length
of performance monitoring process by more
than 80 percent. It is also the only way that can
truly confirm the effectiveness of contaminant
detection at the middle section of a metal
detector’s tunnel.
An important problem in the food
manufacturing processes that shouldn’t be
overlooked is the Fault Reject Rate (FRR)
deriving from metal detectors, which falsely
detect good products as substandard. This is
especially important for snacks or bakery
products as they can considerably affect the
effectiveness and functions of a metal detector
(AKA product effect). An unfit or ineffective
device can hugely compromise the OEE.
The key to constantly maintaining or
improving the OEE rate is the correct and timely
maintenance of machines or equipment.
Preventative maintenance should be clearly
scheduled and carried out accordingly. Relying LINE @MTTH
