Patent ID: 8267572

Claim:
Method for the mechanically protective production of finely dispersed micro-/nanoemulsions with narrow droplet size distribution, comprising: providing a rotating filter fabric unit or a membrane unit with pores within and spaced from an inner wall of a housing by a gap having a varying gap width; forcing a first liquid phase from inside the rotating filter fabric unit or a membrane unit through the pores to the gap between the rotating filter fabric unit or membrane unit and the inner wall of the housing; and flowing a second liquid phase immiscible with the first liquid phase through the gap between the rotating filter fabric unit or membrane unit and the inner wall of the housing such that the drops of the first liquid phase are detached from an outer surface of the filter fabric or membrane unit by their inherent motion in the second liquid phase immiscible with the first liquid phase while superimposed shear flow components are produced by the flow of the second liquid phase and pronounced stretching flow components are produced in the gap due to the varying gap width.
