Visualization of a field being dried in a model saturated 
sample has been carried out. It has been shown that the process of 
moisture extraction under the acoustic action is faster compared to 
the convective action. Criteria dependences of the dimensionless relaxation 
time on the Biot criterion have been obtained. It has been found that 
the acoustic action decreases the coefficient in this dependence without 
changing the exponent
