<p>In the invention, reaction raw-materials composed of a plurality of liquids are sequentially scraped with spiral grooves (7) of one line or more provided in the peripheral face of the rotation shaft (1) rotating within the cylinder wall with the discharge openings being formed therein. The reaction raw-materials (A,B) are uniformly mixed within the grooves (7) by shearing force or twist force through the rotation of the shaft (1). The reaction raw-material (A,B), if in small amount, may be precisely mixed uniformly and is sequentially discharged after the mixing operation. This is suitable for reaction raw-materials which are short in the gelatin condition time from the mixing until the hardening. </p> |
