Patent ID: 8811569

Claim:
A method for estimation of dry mass flow rate in a biological material in an automated procedure, comprising the steps of: conveying the biological material through a measuring station; scan the biological material conveyed through the measuring station with electromagnetic radiation of at least two different energy levels; determine the amount of radiation transmitted through said biological material at said two energy levels; summing, for each of sad two energy levels, the radiation transmission values over a time frame to summed radiation transmission values; estimate a wet dry mass flow rate, M_wet, based on the summed radiation transmission values for said two energy levels; estimate the moisture content, MoistC, of said biological material based on said determined amounts of radiation transmitted through the biological material; and scaling the estimated wet dry mass flow rate, M_wet, in accordance with said estimated moisture content, MoistC, of the biological material, thereby providing an estimate of the dry mass flow rate, M_dry.
