  • Apparatus and method for removal of liquids
    Patent number: 5292421
    Abstract: A first electrode arrangement and a transport element are movable relative to a support. A working space is disposed between the movable elements for advancing moist material along a processing path. As the moist material advances, electrical current is passed through the material between the first electrode arrangement and a second electrode arrangement adjacent the transport element. An acoustic transducer arrangement disposed adjacent the working space simultaneously subjects the moist material to an acoustic field as the material moves along the processing path. The acoustic field is generated by an array of acoustic transducers spaced along part of the processing path.
    Type: Grant
    Filed: February 25, 1992
    Date of Patent: March 8, 1994
