Apparatus for producing emulsions or suspensions

Claim 1

In a centrifugal homogenizing machine for the production of emulsions or suspensions of one material in another material, comprising: a. a housing, b. a rotor rotatably mounted in the housing, and having an end face coaxial with the rotor, rotor ribs projecting axially outwardly from the end face, in concentric and spaced relation defining recesses between successive ribs, c. housing ribs mounted on the housing projecting into the rotor recesses for cooperation of the rotor and Housing ribs for the homogenizing upon rotation of the rotor, d. two supply pipes disposed for concentric introduction, respectively, of said materials centrally towards the end face of the rotor for passage of the material between the rotor and housing ribs, said supply pipes being axially spaced from the end face of the rotor providing a gap between the supply pipes and the end face, e. a housing outlet for effluent from between the rotor and housing ribs, the improvement which comprises: f. said supply pipes being adjustably mounted on the housing permitting adjustment of the axially extended gap between the supply pipes and end face of the rotor.
