A thin-layer evaporator particularly suited for treating high-viscosity fluids, including a treating chamber surrounded by a heating or cooling shell, and a rotor equipped with feed and thrust elements. The feed and thrust elements include at least two axial, equidistant and staggered rows of blade members having the same pitch and sloping with respect both to the rotor axis and to the axial plane passing through their connection line; each member being offset, with respect to the members of the adjacent rows, by a space equal to the half pitch of the member.
