S32, carrying out humidity detection on the material 5 obtained in the step S2 for at least two times and recording the humidity detection as A1、A2；
S33, calculating A respectively1、A2And A0The difference A between1、A2；
S34, determining delta A1And δ A2If the difference between delta A and delta A is the same1And δ A2The same difference between them, the dryness of the mass 5 has reached the standard, if delta A1And δ A2The difference between the two is different, so that the dryness of the material does not reach the standard.
