われことが望ましい特徴をもっている。On the other hand, batch-type horizontal high-viscosity liquid processing equipment calculates the raw material to be processed one time, charges it into a casing, discharges it after the desired treatment is obtained, and then newly processes the next raw material. Therefore, in such a batch method, the degree of reaction changes with the passage of processing time, and for a certain processing time, there is no uniform reaction at any position within the casing. It has the characteristic that it is desirable that they be carried out at the same time.

撹拌・混練されながら進むことになる。That is, the low-speed shaft 2 employs a low-speed stirring blade 4A having fan-shaped blades 5A substantially similar to the low-speed stirring blade 4 shown in the first embodiment, and the high-speed shaft 3 employs a stirring blade 4A having a fan-shaped blade 5A similar to the low-speed stirring blade 4 shown in the first embodiment. A fan-shaped blade 10 similar to the fan-shaped blade 10 of the first embodiment shown in FIG.
Adopts high-speed stirring 3114 with A skewered, and
The direction of the slope of the sector blade 5A of the low-speed stirring blade 4A is the same as the direction of the slope of the sector blade II OA of the high-speed stirring blade 14. Furthermore, a scraping rod 15 is arranged in a continuous spiral at the outer peripheral end of the fan-shaped blade 5A of the low-speed stirring blade 4A, as in the first embodiment. On the other hand, the high-speed stirring blades 14 are sequentially attached to the high-speed shaft 3 with a phase difference of 90°, and these high-speed stirring blades 1
One end of a scraping rod 16 is fixed to the outer peripheral end which becomes the leading side when the No. 4 sector blade 10A rotates, and the other end of this scraping rod 16 is connected to the outside P1 on the leading side of the other adjacent sector blade 10A.
Since it is fixed at the end, the scraping rod 16 is arranged in a discontinuous spiral. Therefore, the high viscosity liquid supplied from the inlet advances in the direction of the arrow a° toward the outlet while being continuously stirred and kneaded.

うに剪断し混練が更に助勢できる。According to the present invention, since the stirring blades rotate between the shafts so as to bite into each other from above, the high viscosity liquid is pushed into the bottom of the casing between the two shafts, and as a result, both sides of the casing in the axial direction It is lifted along the wall side, and the slope of the fan-shaped blade, which has a circular disk cut out, transports the liquid by the thickness of the blade, and the liquid is drawn in by the negative pressure generated on the slope on the opposite side, so it is stirred and kneaded with a simple structure. Moreover, since the tip of the leading side of the fan-shaped blade has an acute angle, it can shear the high viscosity liquid to further assist in kneading.
加えて、厚肉撹拌翼であるため、その内部に熱処理用ジ

更に、断面平行四辺形の羽根であるので、スクレーピン
