Beschreibung
Zusammenfassung:	The invention relates to a method for determining properties of hygroscopic material in real-time during modification wherein, in the method, pieces of hygroscopic material to be modified are stacked and a batch of the hygroscopic material (15) being thereby formed is placed in a modification chamber (11) of a modification apparatus (10) wherein the pieces of the hygroscopic material to be modified are modified. In the method according to the invention at least weight, volume, amount of water in the batch of the hygroscopic material as well as average moisture content of the batch of the hygroscopic material (15) are determined before modification and/or at least once during and/or after modification of the batch of the hygroscopic material (15). The invention relates also to an apparatus for determining properties of hygroscopic material in real-time during modification of the batch of the hygroscopic material (15).
