Abstract
A rotor-stator assembly having a stator and a rotor for mixing and emulsifying materials in which the rotor includes wedge-shaped rotor blades and the stator includes generally V-shaped openings which together impart additional and increased high speed shearing forces and/or pressures on the mixture thereby resulting in a finer reduction of agglomerates and mixture uniformity. The rotor blades preferably comprise a wedge-shaped leading edge and desirably the blades have a V-shaped cross-section. The stator preferably includes a first plurality of elongated, spaced-apart slots, and a second plurality of spaced-apart slots. The slots are disposed so as to define a generally V-shaped configuration around the circumference of the stator.
Claims24
A rotor-stator assembly for mixers and emulsifiers, said rotator-stator assembly comprising:
- a stator comprising a plurality of openings, said plurality of openings being generally arranged in pairs in a generally V-shaped pattern;
- and
- a rotor rotatable relative to said stator, said rotor comprising a plurality of blades and means for supporting said blades for rotation about an axis of rotation, wherein at least one of said blades comprises a surface disposed at an oblique angle relative to said axis of rotation.
A stator for mixers and emulsifiers, said stator comprising:
- a generally cylindrical sidewall within which a rotor is rotatable about an axis of rotation, said sidewall comprising a plurality of openings extending therethrough and arranged generally in pairs to define a generally V-shaped pattern.
