The fixed blades spread the wet feed in a thin layer over the heated wall. The thickness of the layer </ins>is <ins style="font-weight: bold; text-decoration: none;">defined by the clearance between the blade and the heated wall</ins>. <ins style="font-weight: bold; text-decoration: none;">A highly agitated bow wave is formed in front of the rotating blade. The turbulence increases as the </ins>product <ins style="font-weight: bold; text-decoration: none;">passes through the clearance. The volatile component evaporates continuously. The product layer is a few millimeters in thickness.
