を低下させるものである。 Conventionally, this type of granulation method includes the freeze-drying granulation method, but the equipment used in this method is one in which the slurry to be frozen is placed in a pressure vessel, pressure such as air is applied, and the slurry is ejected from a nozzle. Large equipment is required, and atomization requires diluting the slurry and applying high pressure, which consumes a large amount of energy. In addition, the nozzles are difficult to clean and easily clog, the slurry adheres to the stirring shaft, resulting in poor yields, and the spray becomes localized, reducing refrigeration efficiency.

ある。 This invention improves the shortcomings of the conventional equipment as described above, and creates a stirring granulation equipment that is simple in construction and highly efficient, by uniformly dispersing the slurry into fine particles in the stirred vortex-shaped refrigerant liquid. This is what you get.

The propeller screw 3 at the tip rotates and simultaneously rotates the atomizer 2 attached to the center of the shaft 1. The atomizer 2 is disk-shaped and has a wall around it, and a plurality of holes 5 of a predetermined shape are bored in the surrounding wall, and the slurry flowing into the center of the atomizer 2 is blown to the surrounding wall by centrifugal force.
The particles are dispersed and atomized through the holes 5.

状に凍結をされる。 FIG. 3 shows a frozen granulation device using this granulation device, and the granulation device of this invention is inserted into a container 11 containing a refrigerant liquid 9 such as n-hexane, and is operated. . A container 6 containing a cryogen 7 made of ethanol and dry ice is provided outside the container 11, and the refrigerant liquid 9 is cooled by the cryogen 7. As the granulating device operates, the propeller screw 3 rotates, stirring and rotating the refrigerant liquid 9 to generate a vortex around the screw 3. On the other hand, as the shaft 1 rotates, the atomizer 2 also rotates, and the aqueous slurry 8 stored in the container 10 flows onto this disk. This slurry 8 is pushed around the disk by centrifugal force, scatters outward from the holes 5, and at the same time becomes granular. It is evenly distributed almost horizontally into the vortex-rotating refrigerant liquid, and is frozen into granular form while being stirred. be done.
