A METHOD AND DEVICE FOR MEASURING MOISTURE CONTENT DURING OPTIMISING OF A DRYING PROCESS

摘要

A method for measuring the moisture content during drying of an organic material, by which the moisture content in the material is determined based on the dielectric properties of the material, and by which electromagnetic radiation is emitted towards a surface of the material, and the determination of the moisture content is based on the effect of the material on said electromagnetic radiation. A change of the effect of the material on the electromagnetic radiation versus time is detected, and data input to a mathematical model for determining the moisture content of the material during the drying is determined based on the amount of energy consumed for the evaporation of liquid in connection to the drying process during a given time period.
