This invention relates to a method for producing spherical powder.

種々提案されている。BACKGROUND ART Conventionally, various methods have been proposed for producing oily substance powder by cooling and solidifying oily substance particles using a liquid as a refrigerant.
例えば、芯物質としての粉末を分散したワックスを水中

報）が知られている。For example, a method of manufacturing a capsule body by pouring wax in which a powder as a core material is dispersed into water and stirring the resulting atomized wax containing the core material is cooled and solidified with water (U.S. Pat. No. 3,856,699) is known.
しかし、この方法は、比重の大きい水中に比重の小さい

質が限定されるという問題がある。However, this method has the drawback that since wax particles with a low specific gravity are placed in water with a high specific gravity, the wax particles do not settle and are not sufficiently cooled by the water. However, in order to cause wax particles to settle in water, it is necessary to select a core powder with a high specific gravity to be dispersed in the wax, which poses the problem that the core materials that can be used are limited. .

にならないという欠点がみられる。In addition, when the oily substance particles are in the form of capsules, Japanese Patent Publication No. 51-8875, Japanese Patent Application Laid-open No. 51-8176
Methods such as those disclosed in Japanese Patent Application Laid-Open No. 51-8177 and Japanese Patent Application Laid-open No. 51-8178 are known. In these methods, a cylindrical composite jet stream is extruded into a cooling liquid to atomize the particles, and the capsule wall material is cooled and solidified while the fine particles are precipitated together with the cooling liquid to form a capsule body. However, these methods have the disadvantage that the droplets do not become spherical when the interfacial tension between the cooling liquid and the capsule wall material is small.

置の大型化が避けられないという欠点がある。On the other hand, in recent years, a method has been proposed for producing capsules of oil-based substances by using a gas such as air, nitrogen, or carbon dioxide as a refrigerant (Japanese Patent Laid-Open No. 62201635). The method consists of atomizing core material and molten fat into a cooling gas using a triple cylindrical nozzle to solidify the wall material and form a capsule body. However, although this method is effective when producing capsules with small particle sizes, it has the drawback that as the particle size increases, the cooling efficiency deteriorates, making it unavoidable to increase the size of the apparatus.

利に製造するための方法を提供することを課題とする。The present invention has been made in order to solve the problems seen in the above-mentioned prior art, and has good cooling efficiency for forming oily substance particles. It is an object of the present invention to provide a method for efficiently and advantageously producing a powder or granular material of an oily substance, in which the magnitude of interfacial tension can be easily adjusted.
以下本発明の詳細な説明する。The present invention will be explained in detail below.
課 を” するための−
本発明の特徴は、加温溶融した油性物質からなる粒子を
冷却、固化して油性物質の球形粉粒体を製造するに際し
、有機液体またはその水溶液を冷として用いることにあ
る。A feature of the present invention is that an organic liquid or an aqueous solution thereof is used as a cooling agent when producing spherical powder particles of an oily substance by cooling and solidifying particles made of a heated and molten oily substance. It is in.
ここで冷媒として用いる有機液体は、例えばアセトン、
イソブチルアルコール、エタノール、メタノール及びブ
タノール等を包含し、本発明ではこれらの水溶液も冷媒
として用いることができる。The organic liquid used as a refrigerant here is, for example, acetone,
Examples include isobutyl alcohol, ethanol, methanol, butanol, and the like, and aqueous solutions of these can also be used as refrigerants in the present invention.
本発明では、これらの有機液体及びその水溶液を含めて
“有機溶液”ということにする。In the present invention, the term "organic solution" includes these organic liquids and their aqueous solutions.
本発明において冷媒として用いるこれらの有機溶液は、
油性物質の粒子との界面張力が十分に大きいので該粒子
を効率よく球形にすることができる。また、本発明では
、有機溶液が単一成分からなっていてその界面張力が十
分に大きくならない場合には、さらに界面張力の大きい
有機溶液や水などを加えて混合溶液にして上記粒子との
界面張力を大きくする等の調整が可能である。These organic solutions used as refrigerants in the present invention are:
Since the interfacial tension with the particles of the oily substance is sufficiently large, the particles can be efficiently made spherical. In addition, in the present invention, if the organic solution is composed of a single component and its interfacial tension is not sufficiently large, an organic solution with a larger interfacial tension, water, etc. is added to form a mixed solution, and the interfacial tension with the particles is increased. Adjustments such as increasing the tension are possible.
因に、上記有機溶液の界面張力の大きさは、油性物質粒
子を冷却、固化して粉粒体に形成する際、粉粒体の形状
を決定する重要な因子であって、前述したごとく、上記
界面張力が小さい場合には粒子は冷却、同化によって球
形を形成しなくなる。Incidentally, the magnitude of the interfacial tension of the organic solution is an important factor that determines the shape of the powder when the oily substance particles are cooled and solidified to form the powder. If the interfacial tension is small, the particles will no longer form a spherical shape due to cooling and assimilation.

Is the oily substance dissolved in the above organic solution? It is ejected as a jet stream into fl and atomized in the liquid.

なる。The particles of the oily substance thus introduced into the organic solution are formed into spherical shapes by the interfacial tension of the organic solution, and are cooled and solidified while settling or floating in the liquid to become spherical powder particles.
