Abstract: A stream of ground particles is characterized by irradiating it with electromagnetic radiation and detecting electromagnetic radiation emitted from the irradiated particles. The detecting system includes an imaging system and a color image sensor for imaging the particles by way of the electromagnetic radiation emitted by the particles. The color image sensor has sensor image elements for spectrally selective detection of the electromagnetic radiation.

Abstract: A system and method for ground material characterization in a grinding system, in particular for characterizing particles in a ground material stream of ground grain products in a grain grinding system, uses an irradiation section through which at least a part of the ground material stream is fed and with irradiation means for irradiating the particles in the at least one part of the ground material stream with electromagnetic radiation; and a detection section through which the at least one part of the ground material stream is fed and with a detection means for detecting electromagnetic radiation emitted from the particles of the part of the ground material stream fed through the irradiation section. The detection means comprises an imaging system and a color image sensor for imaging the particles onto the color image sensor by way of the electromagnetic radiation emitted by the particles.

Abstract: The invention relates to a system and method for characterization of a particle flow, for example, for characterization of material for milling, in particular for milled cereals, in a roller frame with a roller passage formed by a pair of rollers whereby the system comprises a withdrawal portion after the roller passage for removal of a milled material sample from the milled material flow exiting the roller passage, a presentation section for conveying and presenting the taken milled material sample, a recording device for recording the milled material passing through the presentation section and an analytical section for analysis of the recorded milled material sample.

Abstract: The invention relates to a system for characterizing grinding material, especially milled grain, in a roll mill comprising a roll passage formed by a pair of rolls. The system comprises an extraction device which is analyzed downstream of the roller passages and used to extract a grinding material sample from the flow of grinding material leaving the roll passage; a presentation section for conveying and presenting the grinding material sample; a recording device for recording the grinding material sample conveyed through the presentation section; and an analysis device for analyzing the recorded grinding material sample.
