ABSTRACT:
A sealing device adapted for use in mixing equipment includes a cylindrical packing mantling an end portion of the rotating shaft of the mixing blade with a clearance interposed therebetween, the mixing blade including a shoulder from which the rotating shaft thrusts into a side wall of the bowl, the shoulder having a ring-shaped gasket filled in its surface, the cylindrical packing being extended sufficiently to emerge from the side wall of the bowl, and means for pressing the cylindrical packing against the side wall of the bowl so as to enable the cylindrical packing to come into constant abutment with the ring-shaped gasket, thereby allowing no gap to occur therebetween.
