  • Method of removing solid particles from a mixture comprising a viscous liquid, and separator for the carrying out of this method
    Patent number: 3972813
    Abstract: A method and separator for removing sugar crystals from a syrup. The syrup is continuously delivered to a space defined by an inner conical first perforated wall subjected to air pressure and an outer conical second perforated wall coaxial with the inner conical wall and subjected to a vacuum from outwardly of the space containing the syrup. The perforations subjected to a vacuum are restricted by projections on a plate that extend axially into corresponding perforations and are movable axially therein to maintain these perforations unobstructed by sugar crystals. Rotationally driven scrapers scrape the inner surfaces of the second perforated wall in synchronism with the projections extending into the perforations.
