title: [Hydrodynamic study of a centrifugal differential-contact extractor].
abstract: Centrifugal extractors of the differential-contact type are widely used all over the world in production of antibiotics. Lately, new extractors were developed by Hitachi (Japan). Model E is of a special interest. In the present study the values of the working zone of the Hitachi extractor, EP-02 Ultrex were determined by the pressure levels and the effect of the main parameters characterizing the apparatus hydrodynamic conditions on the minimum and maximum critical pressure was estimated. The results of the study provide wide variation of the hydrodynamic parameters in determination of the most rational extraction conditions.
