Product inspection of nuts, dried vegetables and dried fruit

Across 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. Thanks to a wide range of different detection technologies, our systems can efficiently and reliably live up to this task.

For decades, Sesotec has specialised in systems for industrial contaminant detection. We provide a technologically perfected range of metal detectors and X-ray systems for the reliable detection and automatic removal of contaminants. Our machines and systems of course comply with the special hygienic requirements of the food industry and meet the prescribed standards for audits.

Why is product inspection important with regard to nuts, dried vegetables and dried fruit?

Rising incomes and changing eating habits are creating ever-higher demand for quality among consumers. Accordingly, the demands placed by increasingly globalised food brands and retailers on suppliers are growing as well. As a result, quality issues and contaminants 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 systems.

What are the advantages of automatic systems?

Compared to sorting products by hand, machine-based systems are able to sort out and eliminate contaminants and impurities with much greater precision and consistency. Sesotec systems stand out here for their excellent quality. Thanks to their high capacity level, reliability and low operating costs (energy consumption, wear parts), they amortise quickly. In addition, they help optimise downstream processes, for example by protecting processing machines from damage caused by contaminants. Finally, our systems follow the plug-and-play principle. As a result, they are extremely user-friendly, which is a great benefit to operating staff.

What kinds of contaminants could appear?

The following are examples of contaminants that could enter the products during harvest, transport to storage, subsequent processing steps or through careless staff:

  • Stones
  • Metal
  • Glass

 

What products are inspected?

Our contaminant detection systems are used for a wide range of applications, such as for sorting the following:

  • Almonds
  • Hazelnuts
  • Walnuts
  • Ground nuts
  • Cashews
  • Peanuts
  • Macadamia nuts
  • Pecans
  • Pistachios
  • Apple chips
  • Banana chips
  • Apricots
  • Cranberries
  • Dates
  • Figs
  • Cherries
  • Plums
  • Raisins
  • Beans
  • Peas
  • Lentils
  • Corn


What kinds of technology are used?

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 are also used with conveyor belts, in addition to X-ray inspection machines in particular 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.

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!

How artificial intelligence contributes to sustainable and profitable food processing

Despite the breadth of technology available for foreign object detection, certain types of food products remain difficult to inspect via conventional methods. The reason for this is that some foods have high levels of product effect, which can interfere with metal detection. This white paper examines the phenomenon of product effect, the problems it can cause, and why artificial intelligence offers an innovative and promising solution.

X-ray inspection systems ensure top quality in MANNER products

Founded in 1890, the Josef Manner & Comp. AG is the number one specialist for wafers, dragées, and marshmallow products in Austria. As a leading manufacturer of product inspection technology, Sesotec supplied Manner with three RAYCON x-ray systems to help them renew their IFS certification in 2019. The solution was a success: their IFS certificate was renewed and both production sites continue to operate at the highest level of accreditation.
