きる。With such a structure, the cylindrical trough 1
The material to be kneaded 7 introduced from the inlet 5 of the cylinder 6 forms a predetermined layer thickness S along the inner surface 1A of the cylindrical trough 1 while being conveyed to the downstream side by the screw 6, and while rotating in this state, the upstream region L1 It is sent to the stirring blades 4, 4. In the upstream region L1, a forward conveying force is applied by the stirring blades 4, 4, ...
Inner surface 1 of cylindrical trough 1 while maintaining a predetermined layer thickness S
While swirling along A, it is conveyed at high speed at a conveying speed corresponding to 4 pitches per one rotation, and in the conveying process is primarily kneaded and sent to the downstream region L2. A backward conveying force is applied to the material to be kneaded 7 sent to the downstream region L2 by the stirring blades 4, 4, ...
Therefore, with the layer thickness S increased (about a little more than twice), while turning along the inner surface of the cylindrical trough, 1 every 3/4 rotation.
It is conveyed at a low speed corresponding to the pitch, is secondarily kneaded in the conveying process, and is then discharged from the outlet 8 by the turning of the stirring blades 4, 4 ... Corresponding to the outlet 8. Thus, after the primary kneading in the upstream area L1, the downstream area L
Since the secondary kneading is performed in the state where the layer thickness S is increased by decelerating the transport speed in No. 2, effective kneading is performed particularly in the downstream region L2. Therefore, since the kneading efficiency is greatly improved, if the inner diameter of the cylindrical trough 1 is the same, the axial dimension of the kneading shaft 2 is shortened by half that of the conventional one, and the number of the stirring blades 4, 4 ... As a result, the size of the device can be reduced and the device price can be reduced.

る。As described above, according to the present invention, the stirring blade mounted on the spiral locus in the feeding direction applies a forward conveying force to the material to be kneaded from the inlet side to the middle of the outlet, thereby increasing the speed. In the state of increasing the layer thickness, after carrying, primary kneading in the carrying process and sending to the downstream side, the backward carrying force is applied by the stirring blades mounted on the spiral locus in the anti-feed direction. Effective kneading is performed because the material is conveyed at a low speed and secondary kneading is performed in the conveying process. Therefore, since the kneading efficiency is greatly improved, if the cylindrical trough has the same inner diameter, the axial dimension of the kneading shaft becomes
It is possible to shorten the size of the device by reducing the number of the stirring blades by 2 and reducing the number of agitation blades to be attached.
