  • Patent number: 10173191
    Abstract: A controlled cavitation reactor is disclosed that is particularly suited to the treatment of abrasive fluids and slurries with a minimum of erosion and mechanical failure caused by abrasion. The reactor includes a generally cylindrical housing having a peripheral wall that extends between end plates. A rotor is rotatably disposed in the housing and has at least one outer peripheral surface spaced from the peripheral wall to define a cavitation zone therebetween. A plurality of bores extends through the peripheral surface of the rotor. The rotor may be formed with a central void zone between two lobes of the rotor with each lobe defining a separate cavitation zone with the peripheral wall of the housing. One or more inlet ports is arranged to introduce fluid to the housing tangentially and within one or more void zones. One or more exit ports is arranged to receive fluid from the housing tangentially within another void zone.
    Type: Grant

  • Patent number: 7507014
    Abstract: A controlled cavitation device for mixing and heating of fluids in industries where sanitary conditions must be maintained. The device is easily disassembled for thorough cleaning and then easily assembled for continued operation. All internal surfaces are devoid of angles and are polished to food industry standards to maintain sanitary operation. The controlled cavitation device includes a cylindrical bearing housing for supporting a drive shaft that extends through each end of the bearing housing. An interior end plate is mounted to a C-face mount adjacent to the bearing housing and has a plurality of threaded bores around a periphery. A rotor is mounted adjacent to the interior end plate on the C-face mount. A housing assembly includes a cylindrical housing wall and is mounted on a swing arm assembly that is secured in place adjacent to the rotor.
