Online moisture measurement on cereal, grains and powders

For food products produced by the grain industries, moisture is a crucial issue throughout the manufacturing process. Too little or too much moisture at different stages of production can affect the quality of the final product and the optimisation of production costs. By using microwave technology, it is possible to monitor moisture online, allowing trend analysis and early intervention when necessary. The Berthold moisture systems can measure grain moisture when harvested, throughout processing, and before storage and sale. This significantly reduces production costs and improves product quality. For example, as a rule the moisture content of couscous must not exceed 13.5%.

Early recognition of fluctuations

The MicroPolar system provides real-time, continuous measurement of moisture or dry matter content in a wide range of products. The measurement is performed directly on the main production line. This microwave measurement is nonintrusive; no sensor comes into contact with the product to be measured, which reduces maintenance. The measurement is not influenced by the colour, viscosity or inhomogeneity of the product. Moreover, the measurement is carried out on the entire product. The MicroPolar system is easy to install. The processing unit has a large display and a user-friendly interface. Calibration can also be performed on site.

These are the advantages of Berthold’s moisture measurement used for the food industry:

  • Measures moisture across a representative product path
  • Energy reduction in drying processes
  • Increased yield through reduced amount of rejects
  • Free of wear and maintenance
  • Online process control for real-time process information
  • Highly representative due to transmission principle
  • Easy to install on existing pipelines, vessels, and conveyors
