Abstract
An apparatus for processing materials, such as mixing or homogenizing fluids or dispersing a fluid in a viscous material, comprises a housing having bores and at least one inlet port and an outlet port disposed in the housing and in fluid communication with the bores. A pressure mechanism is disposed outside the housing and is in communication with the inlet port for introducing the materials under pressure to the bore and for forcing the materials through the bores to the outlet port. A rotor is disposed in each bore. The rotors do not contact each other. Each rotor has teeth, and the teeth of one rotor mesh with the teeth of an adjacent rotor so that the materials are squeezed in the space between two adjacent teeth of one rotor and the meshing tooth of the other rotor to impart stretching flow to the materials and to expel the materials from the interstices between the teeth of the one rotor and the other rotor.
