<p>A method and an apparatus for measuring dry mass flow rate for a biological material in an automated procedure is disclosed. The method comprises the steps of conveying the biological material through a measuring station, scanning the biological material with electromagnetic radiation of at least two different energy levels, determining the amount of radiation transmitted through the biological material at said two energy levels, and summing, for each of sad two energy levels, the radiation transmission values over a time frame to summed radiation transmission values. Further, a wet dry mass flow rate, M_wet, is estimated based on the summed radiation transmission values for said two energy level. The moisture content, MoistC, of the biological material is estimated based on said determined amounts of radiation transmitted through the biological material. Finally, the estimated wet dry mass flow rate, M_wet, is scaled in accordance with the estimated moisture content, MoistC, of the biological material, thereby providing an estimate of the dry mass flow rate, M_dry.</p> |
