Abstract
Official abstract text for this publication.
A method for determining and/or monitoring a concentration of maltodextrin and/or maltose in a mashing process comprises method steps as follows: providing a mash, heating the mash to at least one predeterminable temperature, determining the density of the mash determining the velocity of sound in the mash, ascertaining a concentration of maltodextrin and maltose in the mash, and ascertaining the concentration of maltodextrin and/or maltose in the mash.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for determining and/or monitoring a concentration of maltodextrin and/or maltose in a mashing process, comprising: providing a mash; heating the mash to at least one predeterminable temperature; determining the density of the mash; determining the velocity of sound in the mash; ascertaining a concentration of the sum of maltodextrin and maltose in the mash based on the density; ascertaining a ratio of maltodextrin and maltose based on the velocity of sound; and ascertaining the concentration of maltodextrin or the concentration of maltose based on the ratio; wherein a sensor unit is excited by means of a excitation signal to execute mechanical oscillations, the mechanical oscillations are received by the sensor unit and converted into a first received signal, a transmitted signal is transmitted from the sensor unit and a second received signal received by the sensor unit, and density is ascertained based on the first received signal and velocity of sound is ascertained based on the second received signal; wherein the mechanical oscillations and the transmitted signal are produced by the same piezoelectric element of the sensor unit; wherein the first received signal and the second received signal are different signals. 2 . The method as claimed in claim 1 , further comprising: determining a temperature of the mash. 3 . The method as claimed in claim 2 , wherein an influence of temperature is taken into consideration in determining density and/or velocity of sound. 4 . The method as claimed in claim 1 , further comprising: comparing at least one value for the velocity of sound in the mash with at least one reference value or with a value of a characteristic line for the velocity of sound of maltodextrin and/or maltose as a function of concentration of maltodextrin and/or maltose.
