されている。[Prior Art] Solid iodine is handled in its own distinctive state, such as by cooling and solidifying its melt into flakes, sublimated crystals, lumps, powders, granules, etc. Among these, granulated products have advantages such as convenience in packaging and handling during use, and uniform reaction. And, granulation is
The method disclosed in Japanese Patent No. 4427 is to cool and solidify on a rotating disk or cylinder to form flakes, or to cool and solidify into lumps, and then crush them to form granules.
しかし、前記方法は比較的装置や操作が複雑で
困難を招き易い。更に又出来上がつた粒状製品の
表面に一部昇華して粉末化したヨウ素が付着し、
製品価値を下げたり、又これら粉末化物が包装後
にケーキングの原因となる等の欠点がある。 However, the method requires relatively complicated equipment and operations and is likely to cause difficulties. Furthermore, some sublimed and powdered iodine adheres to the surface of the finished granular product,
There are drawbacks such as lowering the product value and causing caking after packaging.
そこで、本件特許出願人は先に特開昭58−
124528号として、溶融ヨウ素を落下させ、途中で
冷却水を霧状に噴霧してヨウ素を球状に固化させ

せる。[Problem to be solved by the invention] In the above method, since cooling is performed using a liquid,
A drying step to remove moisture is required as a post-treatment. Then, during drying, it sublimes, making the surface of the spherical object uneven and losing its metallic luster, reducing its commercial value.
又、得られた球状化物は急激な溶解はせず、安
定した溶解速度をもつという特長を有するもので
はあるが、溶解に時間を要するという問題点があ

更に又、この球状化物は比重が大きいため、液
体と反応させる際液体の底部に沈殿してしまい、
反応が均一に行われ難いという問題点がある。 Furthermore, since this spheroid has a high specific gravity, it precipitates at the bottom of the liquid when reacting with the liquid.
There is a problem that it is difficult to carry out the reaction uniformly.
