What is the Granular Inspection System (GIO series)?

The Granular Inspection System (product name VISCANNER GIO series) is an optical inspection system for automated foreign object and quality inspection of granules, fine granules, and powders.

Typical areas of application:

  • Pharmaceutical products (active ingredient granulates, excipients)

  • Foodstuffs and additives

  • Chemical and functional powders

  • High-quality industrial granulates


The aim is to reliably detect and sort out contaminated particles before the material is further processed or packaged.

Basic principle & structure

The process consists of several clearly defined steps:

  1. Material feed

    • Granulate/powder is fed in via a granule hopper.

    • A constant volume feeder ensures a uniform material quantity.

    • A distribution feeder spreads the material thinly and evenly.

  2. Inspection

    • The material runs on an inspection conveyor belt.

    • High-performance stroboscopic LED lighting from above and below.

    • 3CCD color cameras continuously capture high-resolution images.

  3. Image processing

    • Evaluation is performed using the proprietary VISCANNER GUID system.

    • Combination of:

    • Color processing

    • 3-dimensional full-color analysis

    • Special filter algorithms for foreign object detection

  4. Ejection

    • Detected foreign particles are ejected via an ejection nozzle

    • Defects are sucked out and collected in a separate container

    • Good goods leave the machine separately

What can the system detect?

Detectable foreign objects

  • Black particles

  • Colored particles

  • Hair, fibers, dust agglomerates

  • Metal (optional with magnetic separator)


Inspection performance

  • 100% detection of black foreign objects ≥ 100 µm

  • Minimum detectable particle size: 50 µm

  • Colored foreign objects are reliably detected using color processing

Particular strengths

High inspection reliability

  • Specially developed diffuse lighting for powders and granulates
  • Stable detection algorithms with low error rate


Low operating costs

  • LED stroboscopic light with long service life
  • Reduced rejection rate thanks to precise ejection nozzles


Easy to maintain and clean

  • Tool-free disassembly
  • One-touch quick-release mechanisms
  • Optional washable design (S series)


Traceability and validation

  • Storage of up to 3,000 error images per camera
  • Export as JPEG to USB
  • Reprocessing of stored images for validation and audit purposes
