Milling industry

Infracont grain and flour analyzers provide flour mills with essential support for grading raw materials at intake and for in-process quality control of flours.

From raw material intake to in-process flour control

Infracont's instruments are widely used in the milling industry. The instruments can be used for several purposes: for the quality control of raw materials (wheat, durum, rye, etc.) at the time of receipt, and for the quality control of flours (wheat flour, rye flour, durum flour, etc.) during production.

For the quality control of the raw material, we recommend the Infracont XGrain model, as it has a hectolitre weight module, from which the flour yield of the wheat can be deduced (a higher test weight is often associated with better grain filling and milling characteristics). For the control of flour during production, we recommend the Infracont SGrain, as during flour production it is no longer necessary to use an instrument with a hectolitre weight module, so it is a more affordable solution.

Flours can be measured in cuvettes with the Infracont instruments. In addition to moisture, the gluten, ash and protein content of wheat flour can be measured.

Frequently Asked Questions

Which Infracont analyzer should a flour mill choose: XGrain or SGrain?

The Infracont XGrain is recommended for raw material control at intake, and the Infracont SGrain for in-process flour control. The XGrain has a built-in hectolitre weight module, so it measures the test weight of wheat together with its composition in a single step, from which the expected flour yield can be estimated. In-process flour testing does not require a hectolitre weight module, so the SGrain is the more affordable solution there.

Why is measuring hectolitre weight important when wheat is received at the mill?

Because the flour yield of wheat can be estimated from its hectolitre weight: a higher test weight is often associated with better grain filling and milling characteristics. The built-in hectolitre weight module of the Infracont XGrain measures test weight and composition (moisture, protein, gluten) in a single step, so it can be decided without a separate measurement whether a delivered batch meets the milling requirements.

How can flour quality be measured with a NIR instrument, and which parameters can be determined?

Flour is measured with Infracont NIR instruments by filling it into a cuvette, without chemical sample preparation. In wheat flour, protein, gluten and ash content can be determined in addition to moisture, and the instruments are also suitable for measuring rye and durum flour. The portable Infracont SGrain is one of the few portable analyzers that can also measure flour.
