ABSTRACT OF THE DISCLOSURE Novel and improved methods and apparatus for processing liquid or viscous materials. Essentially, the methods and apparatus involve feeding liquid materials to an annular processing passage for controlled processing. The annular processing passage is provided by two elements. One is a rotatable element carrying at least one processing channel. The other element is stationary and provides a complementary coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material from the passage, an element near the outlet providing a material collecting end wall surface and an element positioned between the inlet and outlet providing a liquid material spreading surface. Rotation of the rotatable element toward the spreading surface provides a coaction between the rotatable element and the spreading surface so that relative movement is established between the rotating inner channel walls and liquid material between the inlet and the spreader surface. Because of the relative movement, the liquid material is spread toward the walls and dragged by the walls through a clearance between the sides of the spreading surface providing member and the side walls as thin layers providing central spaces of the passage downstream of the spreader surface which are free of liquid material. Means are arranged for communicating with the free central spaces to add materials to or withdraw materials from the free central space.
