PURPOSE:To mix and rectify a molten material in an axis extension of a screw and manufacture a flat extruded material without burning or the like by mounting a breaker plate of special structure between a barrel and a die section of a biaxial screw extrusion dryer. CONSTITUTION:A breaker plate 3 is mounted between a die section 1 and a barrel 2. Guide wings 6 are provided vertically and laterally from the peripheral edge in an oblong space 5 of same shape as the inner shape of the barrel of said breaker plate 3, and both faces of said wings 6 are constituted of wing faces in parallel with a screw shaft. The wings are crossingly connected with each other, and crossing sections 7 are positioned on the axis center extensions of respective screws 4 of the biaxial screws. As the guide wings 6 of the breaker plate 3 are crossed at the ends of respective screw shafts, the axis core extensions of a molten material extruded from the screws 4 is guided at the crossing sections, and mixed with the surrounding molten material in a space encircled with wings 6. Therefore, a high temperature bar-shaped section required when the breaker plate 3 is not provided can by eliminated, and as the molten material is fed in the die section in the state of being sufficiently kneaded, a flat-shaped surface without any projection and recesses can be provided at the time of discharging. |
