ABSTRACT:
A basket is so disposed that a portion of the outer periphery thereof is faced to the inner peripheral wall on one side of the tank. The starting materials thrown from the hopper portion formed on the other side of the tank which is opposite to the above inner peripheral wall, are efficiently premixed by the secondary vanes that are rotating near the center of the tank under the basket. The grains of the blend are dispersed by the primary vanes that are rotating in the basket 20 and pass through the slits formed by numerous wires having a circular shape in cross section in the side wall of the basket. Due to the whirling current or vortex current in the basket near the opening and in the tank produced by the stirrer means made up of grooves and/or vanes under the top cover that is provided at the upper portion of the side wall of the basket, the blend near the opening is introduced again into the basket from the inclined surface of the top cover that is downwardly inclined toward the center of the opening together with the dispersing media that have flown from the basket, and is dispersed again.
