Near-Infrared (NIR)

In-line NIR & Camera Instrument - DA 7350

The DA 7350™ is an advanced, modern and versatile in-line NIR instrument for measurement of bulk products such as powders, grains, meals, granules, pellets, slurries and pastes in pipes, chutes, chain conveyors and similar.

It performs real-time multi-constituent measurements of a product in a processing line providing information for process control and quality monitoring.

Continuous real-time in-process measurements helps users increase efficiency and reduce scrap and re-work while improving product consistency and quality. The instrument performs simultaneous measurement of parameters such as moisture, protein, fat, ash, fiber and many others. The core diode array technology provides many benefits including durability, stability, accurate measurement of moving products and the ability to track process changes.

  • Real-time measurements - Monitor, adjust, and optimize your production processes in real-time to save costs, increase yield and improve product consistency.
  • Industry 4.0 Ready - Web based software for easy operation and maintenance.
  • Integrated camera gives production insights - Camera applications are available for color measurements and image analysis for speck counting. Display snap-shots of the production at your operator station.
  • Rugged design to suit production environments - The instrument is designed for the harsh environments of production facilities. It has IP67 & IP 69k ingress protection as well as ATEX and IECEx classifications for installations in potentially dust explosive environments.
  • IoT compatible communication interfaces for easy integration - Industry standard, open communications protocols including OPC UA, PROFINET, ModBus TCP as well as a range of Fieldbuses enable fast and simple information integration with existing plant systems.

  • Measure granules, pellets, powders, pastes, syrups, flakes, liquids and more.
  • Common parameters include moisture, protein, ash, fat/oil, fiber and starch.
  • Many options are available for mounting - all designed for specific uses and products. The DA 7350 can be mounted on pipes, hoppers, conveyors, mixers, before or after dryers, after blending points, before packaging or at other critical points in the process.
  • The DA 7350 builds upon the extensive experience of its predecessor, the DA 7300 which is installed and used at many agri & food production sites worldwide. These are a few examples of its applications.


  • Flour Milling - Maximize flour extraction through accurate real-time ash measurements. Blend wheat and flour streams to reach target specification and use a least-cost raw material. Optimize gluten addition.
  • Starch Production and Corn Milling - Optimize moisture content in meal, starch, bran and germ as well as the use of energy by monitoring and controlling the dryers, control starch-gluten separation stages and ensure consistent product quality.
  • Oilseed Processing - Measure moisture, protein and oil in grain for pricing and binning. Monitor and optimize extraction and drying.
  • Feed milling - Control moisture & fat in mixer. Control the water activity of the end-product. Higher productivity by increasing yield and avoiding faulty batches and rework. Control moisture loss in cooling and additions of molasses/oil.
  • Dairy Processing – Optimize moisture inclusion and reduce energy costs when spray drying milk powder by monitoring product moisture in real-time. Minimize grade change-over time and reduce waste; monitor black particles. Optimize the fat /moisture content of butter.
