The present invention comprises an in-line mixer apparatus for creating output emulsions, homogeneous blends, suspensions and dispersions of pharmaceutical, biological, cosmetic, chemical and food compositions. The mixer includes a drive motor arranged around a support, the motor having an output shaft extending therefrom which is connectable to a drive head. A seal hub is arranged around the shaft, and a plurality of alternation foraminous stator plates and rotors are also arranged about the shaft. An inlet and an emulsion or dispersion discharge is arranged in the drive head. Each of the rotors comprises a plurality of projections for improved compound flow therepast, each projection having a leading cutting edge blade arranged at an acute angle with respect to a frame portion of said rotor member.

1. An in-line mixer apparatus for creating output emulsions and dispersions of pharmaceutical, biological, cosmetic, chemical and food compositions, said mixer arranged to be powered by a drive motor, said mixer comprising: a seal hub arranged around a shaft and disposed in a housing, said shaft arranged to be powered by said motor; an alternating plurality of rotors and foraminous stator plates arranged about said shaft, said rotors and stator plates disposed within said housing, each of said rotors having a radius and an axis of rotation, said rotors each having an arrangement of at least two projections thereon, each of said projections having a leading edge, a trailing edge and a sloped surface between said leading edge and said trailing edge, each of said sloped surfaces sloping in the same direction, said leading edge arranged to be out of alignment with said radius and disposed to scrape by the foramen of one stator and provide a disorienting force whereby to draw material into a throat formed between said leading edge and said trailing edge, said trailing edge being arranged to scrape by the foramen another stator and force emulsions and dispersions into the foramen of an adjacent foraminous stator plate whereby to provide shear and turbulence thereby increasing dispersion and emulsification; and a feed tube disposed on a distal end of said housing and an emulsion or dispersion discharge means arranged through a proximal end of said housing. 2. The in-line mixer apparatus as recited in claim 1 wherein each of said rotors has a frame edge defining a side of said throat, and each said leading edge is arranged at an acute angle with respect to said frame edge. 3. The in-line mixer apparatus as recited in claim 1 wherein said leading edge is parallel to and spaced apart from the radius of rotation of said rotor. 4. The in-line mixer apparatus as recited in claim 1, wherein further including small vanes in the crotches between adjacent projections whereby to enhance turbulance between said projections.
