the globe, the trend towards discerning customers who demand top-quality food
is growing. For manufacturers of nuts, dried vegetables and dried fruit, it is
essential to detect and eliminate contaminants, impurities and quality issues.
Thanks to a wide range of different detection technologies, our systems can
efficiently and reliably live up to this task.
For decades, Sesotec has specialized in systems for industrial materials
sorting and contaminant detection. We provide a technologically perfected range
of optical food-sorting systems, metal detectors and X-ray systems for the
reliable detection and automatic removal of contaminants and products that do
not meet strict quality standards. Our machines and systems of course comply
with the special hygiene requirements of the food industry and meet the
prescribed standards for audits.
Rising incomes and changing eating habits are creating ever-higher demand for quality among consumers. Accordingly, the demands placed by increasingly globalized food brands and retailers on suppliers are growing as well. As a result, quality issues and contaminants – from discoloration to metal filings – pose an increasing risk to a company’s sales and reputation. The only way to counteract these concerns effectively and efficiently is with assistance from automatic product inspection and sorting systems.
The following are examples of contaminants that could enter the products during harvest, transport to storage, subsequent processing steps or through careless staff:
Apart from contaminants, it is necessary to prevent other forms of contamination and flaws in appearance, such as the following:
Our contaminant detection and sorting systems are used for a wide range of applications. Here are some examples that, depending on the nature of the product, can be inspected or sorted:
Metal detection and X-ray inspection
Nuts, dried vegetables and dried fruit can be inspected loose as bulk
goods. For this particular application, Sesotec offers what are known as
free-fall metal detectors. Fed in through pipes, the products undergo
inspection and the systems reliably separate out metal contaminants from the
bulk goods through reject flaps. Metal detectors with conveyor belts and, in
particular, X-ray inspection machines are also used for already packaged
products. As part of the final check, products are inspected for metal and
other contaminants to ensure optimum quality before being shipped out.
Color, infrared wavelengths, dimensions and thickness are key criteria used to distinguish nuts, dried vegetables and dried fruit from one another and from contaminants for safe sorting. Depending on the specific application, our systems can be equipped with the following detection technologies:
Thanks to our many years of experience with materials sorting and
contaminant detection, we cover the entire range of technology with proficiency
and professionalism. Based on our modular designs, we can find a tailored,
economical solution for your particular need. Simply contact us − we would be
happy to advise you!
