The high shear mixing device comprises a first screw kneader and a second screw kneader; a first rotation driving mechanism configured to rotate the first screw kneader and a second rotation driving mechanism configured to rotate the second screw kneader; a revolution driving mechanism including the first rotation driving mechanism and the second rotation driving mechanism rotatably installed therein; a driving mechanism body including the revolution driving mechanism installed therein; and a mixing tank. Each of the first screw kneader and the second screw kneader comprises a shaft having one end connected to the rotation driving mechanism; and three or more blades having one end fixed to the shaft and having a helically curved body along the longitudinal direction of the shaft, and the first and second screw kneaders rotate in opposite directions with their blades overlapping each other.

Described is a stirrer for liquid, semi-liquid or semi-solid products, including at least the following, in combination: a central shaft; a plurality of radial supports, connected to the central shaft; a plurality of mixing and centring elements, each configured to be connected to a radial support so as to define a first operating configuration for processing liquid or semi-liquid products; a plurality of vanes, each configured to be connected to a mixing and centring element so as to define a second operating configuration for processing semi-solid products.

A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.
