A mixing apparatus includes a mixer configured to mix a material including a rubber or a resin in the presence of a working fluid that is in a supercritical state or a subcritical state. The mixer includes a chamber that forms a flow passage for the working fluid and the material, and a mixing blade disposed in the chamber and fixed to the chamber.

Mixing apparatus

The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.

Apparatus for mixing materials dissolved in a high-pressure working fluid

A screw extruder which extrudes a kneaded material includes a screw having a helical flight provided on an outer peripheral surface of a shaft portion thereof, and a chamber housing the screw. In the screw extruder, a flight thickening portion is provided at a part which is a tip portion of the flight and is on the reverse side of a rotation direction of the flight.

Screw-type extruder

A sealed kneading machine includes a kneading chamber to which a material to be kneaded is supplied, and a rotor disposed in the kneading chamber to be able to rotate about a rotor shaft. The rotor includes a plurality of kneading blades for kneading the material to be kneaded, and the length of all the kneading blades in the rotor shaft direction of each thereof is 45% or less of the total length of the rotor in the rotor shaft direction.
