Why is product inspection and sorting important with regard to spices and seasonings?

The production of spices and seasonings is a complex process. The aim is to produce and deliver pure products. Sorting systems and product inspection systems increase product safety and ensure top quality.


What purpose do Sesotec product inspection and sorting systems serve?

The sorting and inspection of unpackaged spices and seasonings, as well as packaged products such as salt and sugar, target impurities and contaminants. Ranging from optical sorting to contaminant detection using magnets, inductive metal detectors and X-ray technology, many different methods are available to inspect and sort spices and seasonings for a variety of impurities and contaminants.


Benefits of Sesotec sorting systems and contaminant detection in the food industry:

  • Precise detection and removal of contaminants
  • Precise removal of impurities
  • Consistent performance (in contrast to sorting by hand)
  • User-friendly operation (plug-and-play principle)
  • Reliable functionality
  • Designed for high capacity levels
  • Low total cost of ownership (energy consumption, wear parts)
  • Rapid amortization
  • Optimization of downstream processes (machine protection)

What kinds of contamination and quality issues could occur?

Potential contamination and quality issues with regard to spices and seasonings can occur during processing as well as due to staff carelessness. Common examples include stones, metal and glass, although our machines can detect and remove many other contaminants.


What spices and seasonings are inspected and sorted?

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:

  • Salt
  • Sugar
  • Spice mixes
  • Baking agents
  • Yeast
  • Pudding powder
  • Potato flour
  • Read-to-drink tea/coffee
  • Much more


What kinds of technology are used in Sesotec systems?

Sesotec possesses sound expertise across a wide range of technology. Thanks to our carefully considered combination of sensors and software, we achieve outstanding results when it comes to product inspection and sorting. The systems function using the following sensors, among others:

  • Inductive metal detectors
  • X-ray technology (e.g. analysis of thickness, chemical composition, etc.)
  • Latest camera technology (color analysis similar to the human eye)
  • Shape recognition (analysis of geometrical shapes)
  • InGaAs technology (detection of foreign materials such as stones)


How do producers of spices and seasonings use our machines?

Optical sorting systems are mainly used in the production process to sort unpackaged products based on a range of criteria. As a result, our sorting systems ensure a high level of quality throughout the entire process and can be adjusted precisely to your needs.

In contrast, Sesotec product inspection systems are normally used in the outgoing goods area and ensure as part of the final step that only flawless goods are delivered to the customer.
