Meeting demands – maintaining standards The challenges of the snacks and potato processing industry

  • Keeping consumers happy

    Snacks and potato products are popular, yet the large target market is very discerning. Even the smallest variations in flavor, salt or fat content are noticeable and can lead to changes in consumption habits and outspoken feedback, as well as losses of market share and image.

  • Controlling quality constantly

    Natural raw ingredients vary. Nevertheless it is important to produce a consistent product that fulfils supplier demands, regulatory guidelines and environmental standards.

  • Reducing losses

    Variations in levels of fat, moisture, starch and flavoring can lead to batches being rejected. Precise ingredient measurement, analysis and management is necessary to make the most of your raw materials and react quickly to keep production on track.

  • Keeping production running

    On high volume snack production lines, measurement and analysis needs to be quick and happen continuously in real time. The key is being able to react immediately to variations. This keeps things moving and avoids interrupting processes and reducing productivity.

  • Producing products sustainably

    Efficient processes use fewer resources to make more product. Exact measurement and snack product analysis is necessary to ensure nothing goes to waste and snack and potato products can be made with lower levels of energy and CO2 emissions.

Our solutions for your snacks and potato products

  • Corona® extreme mounted to a downpipe using a power flange

    Corona® extreme

    Data about critical parameters for snack and potato products like fat, moisture, starch and sugar are provided instantly – even in the most challenging conditions. Optimize your production in real time and ensure you always adhere to exact recipes to deliver superior quality. Improve profitability and make better use of natural resources thanks to precise measurement.

    • Works in tough environments with dust, debris and vibration, temperatures of -15 °C to 50 °C and shocks of up to 50 g
    • Ideal for measurement at pipelines and other closed transport systems
    • Can be used in process (inline), at the line or in the lab thanks to excellent measurement performance
    • Performs reliable, near-infrared (NIR) measurement of snacks and potato products continuously
  • Corona® process over conveyor belt at tortilla chips factory

    Corona® process

    Giving you all the information you need to ensure quality stays consistent, near-infrared measurement covers ingredients, such as fat, moisture, starch and sugar, while visible measurement keeps an eye on true color values. Adjust when necessary thanks to real time data and improve yields with precise information about batches and material usage.

    • Can be used above a conveyor belt or blender directly in the production line
    • Measures ingredient composition (fat, moisture, salt) and external appearance (color) simultaneously
    • Provides increased safety, thanks to backup lamps for continuous measurement
    • Performs reliable, near-infrared (NIR) and visible measurement of snacks and potato products continuously, irrespective of the distance to the sensor to the sample
