  • Patent number: 8961001
    Abstract: Provided are an agitator and an agitating hook provided therein. The agitator includes a rotary shaft rotatably installed in a reactor, rotor blades installed at an outer circumference of the rotary shaft and rotated with the rotary shaft to agitate a material therein, and an agitating hook constituted by a pair of members spaced apart from each other at an inner wall of the reactor and through which the rotor blades pass. Here, a gap between the agitating hook is larger at an outlet port through which the rotor blade leaves than at an inlet port through which the rotor blade enters. Since a pressure is uniformly applied from the inlet port through which the rotor blade enters to the outlet port through which the rotor blade leaves, a torsional moment applied to the agitating hook is minimized. Therefore, it is possible to improve durability of the agitating hook and increase reliability of products.

The outer surface of the blade and the second end define an inside blade diameter “ID” and the outer surface of the blade and the first end define an outside blade diameter “OD”. The blade is positioned within and coaxial to the vessel. A scotch yoke, operatively connected to the blade by a shaft, effects reciprocating longitudinal movement of the blade through a stroke “S”, with a duration “T” for each stroke, wherein 175?0.36×OD2/ID2×S/T?250 when OD, ID and S are expressed in inches, and T is expressed in minutes.

  • Patent number: 7271237
    Abstract: A method for drying a material such as a polymer hydrogel which passes through a cohesive phase as it dries is disclosed. The method comprises agitating a composition while removing liquid until the solids content of the composition reaches a level at which the composition enters a cohesive phase, halting agitation, removing liquid from the composition in the absence of agitation, and resuming agitation. Practice of the present invention can eliminate the problems associated with adhesion of a material to itself and to process equipment during the cohesive phase.
