Abstract:
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.
